Terms & Conditions

1. Agreement and definitions

These Terms & Conditions ("Terms") govern access to and use of Avum, including its Sync Rules and Unified Calendar, the avum.io website, related applications, and support services (collectively, the "Service"). The Service is provided by Pentatope Technologies Kft. ("Provider," "we," "us," and "our") under the Avum brand. "User," "you," and "your" mean the person or entity accepting these Terms.

By creating an account or using the Service, you confirm that you have read and agree to these Terms. If you later complete Paddle checkout, you also agree to the terms presented for that purchase and subscription. If you do not agree, do not use the Service or complete checkout.

A "Consumer" is a natural person acting outside their trade, business, craft, or profession. A "Business User" is any person or entity using the Service for professional or commercial purposes. Group-specific provisions apply only to that group, and mandatory law prevails over any conflicting term. Where you are a Business User and the Provider processes personal data on your behalf as a processor, our Data Processing Addendum forms part of these Terms and applies only to that processing. It does not apply to Consumers or to processing for which the Provider is a controller. Our Privacy Policy explains how we handle personal data.

2. Service provider and contact details

Hosting providers

3. Eligibility and authority

Each individual who uses the Service must be at least 18 years old and have the legal capacity to enter into a binding agreement. By using the Service, you represent that you meet these requirements.

If you use the Service for an organization, you represent that you are authorized to accept these Terms for it and connect the relevant accounts and calendars. In that case, "you" includes the organization. You must keep registration, billing, and contact information accurate. We may require reasonable verification to prevent fraud, unauthorized access, or misuse.

4. What Avum does

Avum connects supported Google and Microsoft accounts, lists calendars available through those accounts, applies the Sync Rules you configure, and provides a Unified Calendar. Depending on your settings, the Service may read event information and create, copy, transform, update, or delete events.

You decide which accounts and calendars to connect, which calendars act as sources and destinations, and which information is synchronized. Enabling a Sync Rule instructs Avum to carry out the corresponding operations, including changes and deletions needed to keep events consistent.

The Unified Calendar lets you view, search, and manage events using your existing provider permissions. It acts only when you request an operation. Moving an event may require creating it in the destination calendar and deleting or cancelling the source event, which may notify attendees.

The Unified Calendar uses the same connected-account OAuth tokens and provider permissions as Sync Rules and requires no additional OAuth scopes. It processes event details transiently and does not store them for this feature. Avum may retain content-free technical identifiers and operation status to prevent duplicates or recover an incomplete move. Features and limits depend on your plan, provider permissions, and relevant technical settings.

5. One user per account and subscription

An individual Avum account is personal to one natural person and may not be shared, transferred, or used jointly. You may not share authentication links, sessions, or other account access.

All provider accounts connected to one individual Avum account must belong to, or be individually assigned to, the same person. One person may connect several accounts they are authorized to use. One subscription covers one Avum account unless an expressly offered multi-user plan says otherwise.

6. Connected accounts and provider permissions

You may connect only an account you are authorized to access and use with a synchronization service. You must comply with the account provider's terms and any rules imposed by the organization that owns or administers the account. Access to a calendar through Google or Microsoft does not by itself establish that you are legally entitled to copy or disclose all information in that calendar.

You authorize Avum to use the provider permissions you grant only as described in these Terms, your Sync Rule settings, your actions in the Unified Calendar, and our Privacy Policy. You may disconnect an account through Avum and may revoke access through Google or Microsoft. Changes to authorization or provider access can interrupt synchronization and Unified Calendar features.

When you disconnect an account or delete a Sync Rule, we attempt to clean up event copies previously written to another calendar. However, external factors may prevent or limit that cleanup, and you remain responsible for reviewing and, where appropriate, removing any remaining copies.

7. Calendar information and your responsibilities

You retain any rights you hold in calendar information processed through the Service. You grant the Provider a limited, non-exclusive right to process that information only as necessary to provide, secure, maintain, and support the Service, comply with law, and enforce these Terms.

Calendar information may incidentally reveal health information, religious or philosophical beliefs, political opinions, trade-union membership, sexual orientation, or other sensitive information. Avum does not prohibit an ordinary calendar event merely because it refers to such a matter.

Avum is a general-purpose calendar service. Unless the Provider expressly agrees otherwise in writing, the Service is not offered for use that would require the Provider to act as a business associate under HIPAA or to satisfy sector-specific obligations governing a customer's regulated records, including GLBA customer information. The Provider does not currently enter into HIPAA business associate agreements. This restriction applies to regulated organizational workloads, not to personal calendar entries that happen to mention healthcare, financial, religious, political, or similarly sensitive matters.

You are responsible for:

• having all rights, permissions, and lawful grounds needed for the calendar processing you direct.
• minimizing the information synchronized and choosing settings and destination calendars appropriate for confidential information and other people's data.
• reviewing Sync Rules and Unified Calendar operations before relying on or submitting them.
• acting on provider warnings and Avum errors where continued operation could cause harm.
• maintaining independent records or backups where loss would have significant consequences.

Avum is not an archival or backup service, and the Unified Calendar is not a separate store of your event details. Do not use the Service to copy information to a calendar whose viewers should not receive it.

8. Electronic contracting, Paddle, prices, and subscriptions

How the contract is concluded

Creating an Avum account and accepting these Terms concludes the Service agreement with the Provider. If you are eligible, Avum then activates a 30-day free trial without requiring payment details or a Paddle transaction.

To purchase a subscription, you separately select a plan and monthly or annual billing, review the payment obligation in Paddle checkout, and submit the transaction. You can correct input errors before submitting. Paddle's electronic confirmation concludes the purchase and subscription agreement with the applicable Paddle entity under its Buyer Terms. The subscription entitles you to continued use of Avum under your existing Service agreement with the Provider.

If you complete checkout during an active trial, Paddle creates the subscription, but the trial continues under its existing conditions until its original end date. Completing checkout does not shorten the trial, change its eligibility rules, or cause an immediate subscription charge. Unless you cancel or withdraw from the subscription before its scheduled first charge, paid billing begins when the trial ends. If you do not complete checkout, no subscription is created and no automatic charge occurs. Review the price, billing interval, first charge, renewal, and cancellation terms before submitting.

The Service agreement with the Provider is concluded electronically in English. It is not treated as a separately signed paper contract or individually filed by the Provider. Paddle provides the transaction confirmation in a durable electronic format. The Provider and Paddle retain account and transaction records as described in their notices. The version identified at checkout governs and can be saved or printed. We provide required contract information in a durable form where mandatory law requires it.

After checkout, supported account or payment details can be updated through Avum or Paddle. The Provider has not subscribed to a separate voluntary code of conduct for the Service.

Paddle and recurring payments

Paddle is the Merchant of Record and authorized reseller for all sales of Avum subscriptions. Paddle administers the purchase, billing, subscription, withdrawal, and refund processes under its Buyer Terms. These Terms govern the Provider's supply of Avum.

The Provider remains responsible for Service delivery, support, and applicable digital-service conformity. Paddle's role does not remove any non-waivable duty or remedy. Each set of terms applies to its own scope. Mandatory and expressly additional consumer rights remain unaffected.

The plan, billing interval, price, currency, applicable taxes, first charge date, and renewal terms are displayed at checkout. Monthly and annual subscriptions renew automatically for successive periods of the same length until cancelled. If you subscribe during an active trial, you authorize Paddle to charge the payment method provided at checkout when the trial ends and on each renewal date, unless you cancel the subscription before the applicable charge.

Prices may change for future billing periods. Paddle or the Provider will give any notice required by law before a new price applies, and you may cancel before an increase takes effect.

9. The 30-day trial

Each eligible natural person may redeem one 30-calendar-day Avum trial in their lifetime. The trial begins when registration is completed and Avum activates the trial. No payment details are required, no Paddle transaction is created merely by starting the trial, and no subscription fee is charged during it.

Each connected-account email address may be used with one trial only. To enforce trial eligibility, Avum compares a normalized connected-account email with a pseudonymous keyed-digest record, as explained in the Privacy Policy. We may use reasonable account, connected-account, and, where applicable, transaction information to refuse or end duplicate, abusive, or ineligible trials. A previously trialled account may still be used with a paid subscription.

The trial itself does not need to be cancelled to avoid a charge because registration alone does not create a paid subscription. During the trial, you may select a paid plan and complete Paddle checkout. Subscribing does not restart, shorten, extend, or otherwise change the trial or its original end date. If you cancel the Paddle subscription before its scheduled first charge, Paddle will not charge the subscription fee, and your free-trial access will continue under the same conditions until the original trial end date. If you do not cancel, the selected paid billing period begins when the trial ends and Paddle charges the price shown at checkout.

10. Consumer withdrawal rights

The cancellation, withdrawal, and refund terms applicable to your transaction are those set out in Paddle's terms and policies, including its Refund Policy. Any mandatory rights available to you under applicable law remain unaffected.

How to withdraw

As Merchant of Record and authorized reseller, Paddle administers purchase-side withdrawals and payment refunds. Use any online withdrawal function provided in your transaction confirmation, billing page, or Paddle buyer portal. You may also make an unequivocal withdrawal request through Paddle buyer support.

Withdrawal rights and procedures are subject to applicable law and Paddle's terms and policies for your transaction.

Paddle's role does not remove any separate withdrawal function or confirmation duty that mandatory law places on the Provider.

Model withdrawal statement

You may use the following statement, but its use is not mandatory: "To the applicable Paddle entity identified in my transaction confirmation and Pentatope Technologies Kft.: I hereby give notice that I withdraw from my Avum subscription contract concluded on [date]. Name: [name]. Address: [address]. Account email: [email]. Paddle transaction or subscription ID: [identifier]. Date: [date]." A signature is required only if you send the statement on paper.

Effect of withdrawal

A valid withdrawal ends the affected agreement and access may cease. Paddle administers any refund within the time and by the method required by law. Starting a free trial alone does not create a payment to refund. If you purchase a subscription during the trial, withdrawal and refund rights relating to that purchase are governed by the terms presented at checkout and applicable law. Mandatory withdrawal, refund, price-reduction, termination, and conformity rights remain unaffected.

11. Subscription cancellation, account deletion, and refunds

You may cancel a Paddle subscription at any time through the Paddle buyer portal or another cancellation method Paddle makes available. If you cancel during an active trial and before the scheduled first charge, Paddle will not charge the subscription fee. Cancelling the subscription does not cancel, shorten, restrict, or otherwise change the trial. Free-trial access continues under the same conditions until the original trial end date. If you cancel after paid billing has begun, cancellation takes effect at the end of the current monthly or annual billing period. You may continue using paid features until then, and Paddle will not charge another renewal after cancellation takes effect.

Account deletion is a separate data-removal action, not subscription cancellation. A deletion request immediately disables synchronization and restricts normal account use, even if paid time remains. Permanent deletion is scheduled after a seven-day grace period and may be canceled before the displayed deadline. We will make a best-effort attempt to remove events the Service created, but provider access problems may leave copies that you must remove yourself.

During the grace period, we take steps to prevent further renewal and cancel the linked subscription when deletion completes. If an automatic recurring renewal is completed after the deletion request but before we request cancellation, we will submit a full-refund request through Paddle. Payments completed before the deletion request remain paid, and deletion does not otherwise create an automatic refund or credit for unused paid time.

These rules do not affect any withdrawal, refund, digital-service conformity, or other right required by law or provided under Paddle's applicable policies. Ending Avum does not cancel services supplied by Google, Microsoft, or another calendar provider.

12. Upgrades, downgrades, and feature limits

If you change the selected plan or billing interval while an active trial is still in progress, the trial and its original end date remain unchanged, and the change does not cause an immediate charge. The new plan and price apply when paid billing begins, unless you cancel the subscription before the scheduled first charge. After paid billing has begun, plan changes may take effect immediately, and Paddle calculates any applicable prorated charge or credit at the time of the change.

A downgrade may be blocked until your active Sync Rules and settings fit the lower plan. If paid access ends instead, the Provider may disable affected features.

13. Education Discount

Where the Education Discount is enabled, the Provider provides an Education Discount of at least 30% from the standard price. The percentage shown at checkout applies. It is conditional, personal, non-transferable, and cannot be combined with another offer unless stated.

Eligibility requires an authorized education-domain account, an authorized personal account, and an enabled Sync Rule between them. Domain matching establishes offer eligibility only. It does not imply an institutional affiliation or endorsement.

If eligibility ends, a three-calendar-month grace period begins. We send an initial notice and a reminder before the first standard-price charge. Restoring eligibility preserves the discount. Otherwise, the current standard price applies from the next charge. Delivery failures do not extend the grace period, and you may cancel before the charge.

The Provider may require reasonable reverification and may withhold or remove a discount obtained by misrepresentation, account sharing, or circumvention of the eligibility rules. We will not retroactively charge the discount difference for a period in which the discount was applied in good faith.

14. Acceptable use

You must not use the Service to:

• break the law, infringe another person's rights, or breach a binding obligation.
• connect an account, calendar, or data source without sufficient authorization.
• share an individual account or synchronize provider accounts belonging to different people.
• circumvent plan limits, trial limits, eligibility checks, or technical safeguards.
• introduce malware, probe for vulnerabilities without written authorization, interfere with the Service, or impose an unreasonable load on it.
• resell, sublicense, or provide the Service to third parties unless an applicable plan permits it.
• reverse engineer or attempt to derive non-public source code, except to the limited extent such a restriction is prohibited by law.
• use the Service to harass, deceive, surveil, or cause harm to another person.

15. Account security

You are responsible for securing your Avum access and connected accounts. Notify us promptly if you suspect unauthorized access, and do not allow another person to use your authentication or active session.

We may take reasonable protective measures affecting account access or connections where necessary to protect users, connected providers, or the Service.

16. Support

Support is available through contact@avum.io. We aim to respond reasonably but promise no specific response time unless a written service-level agreement applies. A request authorizes inspection of relevant account and diagnostic information, not unrestricted access to calendar content. Human access is governed by Section 7 of our Privacy Policy.

17. Avum intellectual property

The Provider and its licensors own the Service and its related materials, except for information supplied by users or third parties. Subject to these Terms and your applicable plan, the Provider grants you a limited, non-exclusive, non-transferable right to use it for its intended purpose during your account term. You may not assign or transfer your Avum account or these Terms without our written consent. The Provider may assign these Terms as part of a reorganization or transfer of the Service, subject to applicable law.

If you provide suggestions or feedback, you grant the Provider a worldwide, perpetual, royalty-free right to use it without restriction or payment, provided that doing so does not identify you or disclose your confidential calendar information contrary to our Privacy Policy.

18. Availability, providers, and changes to the Service

Avum supplies an integration layer. It does not supply or control the underlying Google or Microsoft accounts, calendars, APIs, or provider services. Their availability and continued authorization are prerequisites for Avum's connected-calendar features. Avum also depends on independent cloud, payment, and communications infrastructure. These dependencies and other events outside our reasonable control, including provider or infrastructure failures, network outages, cyberattacks, government actions, or natural events, may delay or prevent Service operations. We take reasonable steps to limit the impact and resume operations but do not guarantee uninterrupted, immediate, or error-free operation.

We may modify, suspend, or retire affected functionality where reasonably necessary for security, legal compliance, provider compatibility, or reliability. A Consumer-facing change during a continuous contract will have a valid contractual reason, impose no extra cost, and be communicated clearly. If it materially and adversely affects use or access, we will give at least 30 days' durable notice, and the Consumer may terminate free of charge within 30 days after receiving the notice or the change taking effect, whichever is later. Advance notice is not required where law permits an urgent exception. All mandatory remedies remain available.

19. Suspension and termination

We may suspend or terminate access if you materially or repeatedly breach these Terms, fail to pay an amount due, use the Service unlawfully, create a security or operational risk, abuse an offer, or if a provider or competent authority requires us to act.

Where appropriate and legally permitted, we will give notice and a reasonable opportunity to remedy a breach. We may act immediately where delay risks harm, compromises an investigation, or violates law or provider requirements.

You may stop using Avum at any time. Subscription cancellation, account deletion, and provider disconnection are separate actions. Accrued payment obligations remain due despite suspension, termination, or an event outside a party's reasonable control, subject to mandatory Consumer rights. Provisions that by their nature should survive termination, including intellectual-property protections, liability provisions, and dispute terms, continue to apply.

20. Conformity, service-issue remedies, and disclaimers

Consumers retain all mandatory rights relating to digital-service conformity, re-performance, price reduction, termination, refund, or damages. If Avum does not work as required by applicable consumer law, contact us so we can investigate and provide the required remedy. During a continuous contract, we provide and notify Consumers of updates, including security updates, needed to keep Avum in conformity as required by law.

Please report a suspected Service failure promptly and provide information reasonably needed to investigate it. Where appropriate, the Provider will first seek to restore the affected functionality within a reasonable time and without charge. This reporting and cooperation request does not reduce a Consumer's mandatory rights or reverse any burden of proof imposed on the Provider by law.

Subject to mandatory law, if a verified material failure made paid Service functionality unavailable or non-conforming, the financial remedy is limited to the portion of the subscription price attributable to the period and extent of the failure. No price reduction, credit, or refund is due for an earlier period during which the Service was in conformity. If a Consumer validly terminates the contract, any mandatory refund may also include prepaid charges attributable to the period after termination.

For contractual refunds, credits, and extensions, a verified Service failure means an Avum-specific failure. It does not include a failure or restriction of an underlying provider service, provider API, connected account, authorization, external infrastructure, or network that prevents Avum from performing the integration as designed. A Business User may seek a remedy or damages for such an external failure only if a separate written service-level agreement provides one or the Provider caused or materially contributed to it. For Consumers, an external cause does not remove a conformity remedy imposed by mandatory law, but the Provider is not liable for damages where the legal conditions for exemption are met or for loss that would have occurred even if the Provider had performed correctly.

Instead of a refund or account credit, the Provider may offer to extend the current subscription or defer the next renewal date by up to the verified period of material impairment. For a Consumer, an extension replaces a monetary remedy only if the Consumer accepts it and applicable law permits that choice. For a Business User, the Provider may choose between a proportionate refund or credit administered through Paddle and an equivalent subscription extension. These are the Business User's sole and exclusive remedies for Service unavailability, delay, error, or non-conformity.

Subject to those mandatory rights, Avum is provided on an "as available" basis. We do not promise uninterrupted or error-free operation or compatibility with every configuration. Future-feature descriptions are not release commitments. Business Users must determine whether Avum meets their operational and regulatory needs. A service level applies only when agreed in writing.

21. Business confidentiality

This Section applies only to Business Users. "Confidential Information" means non-public information disclosed by or on behalf of one party to the other in connection with the Service that is identified as confidential or reasonably should be understood as confidential. It does not include information the receiving party can demonstrate became public without breach, was lawfully known or received without restriction, or was independently developed without using the Confidential Information.

Each party will use the other's Confidential Information only to perform or exercise its rights under these Terms, protect it with reasonable care, and disclose it only to persons who need it for that purpose and are bound by equally protective confidentiality duties. A required disclosure is permitted if the receiving party, where legally allowed, gives prompt notice and reasonable assistance in seeking confidential treatment. These duties survive while the information remains confidential and do not limit stricter duties under the Data Processing Addendum or applicable law.

22. Liability

Liability that is never excluded

Any liability that cannot lawfully be excluded or limited remains unaffected. This includes liability for fraud or fraudulent misrepresentation, intentional misconduct, gross negligence where limitation is prohibited, death or personal injury caused by negligence, and any mandatory consumer liability or remedy.

Events outside reasonable control

Subject to applicable law, a party is excused from liability for delay or failure caused by an event beyond its reasonable control when the party could not reasonably have foreseen, avoided, or overcome the event.

Consumers

The Provider is liable to Consumers only to the extent required by applicable law.

Business Users

To the fullest extent permitted by law, the Provider has no liability to a Business User beyond the exclusive remedies in Section 20. In particular, the Provider is not liable for any direct, indirect, incidental, special, or consequential loss, loss of profit, revenue, anticipated savings, business opportunity, goodwill, or data, cost of substitute services, or a third-party claim arising from use of, inability to use, delay, error, or failure of the Service. If applicable law does not permit that exclusion in a particular case, the Provider's aggregate liability is limited to the subscription price attributable to the verified period of material impairment giving rise to the claim.

A Business User will indemnify the Provider against third-party claims and reasonable resulting costs to the extent caused by that Business User's unlawful calendar processing, unauthorized account connection, or material breach of Sections 5, 6, 7, or 14. This obligation does not apply to the extent the claim was caused by the Provider's own breach, negligence, or unlawful conduct.

23. Complaints and consumer dispute resolution

Send complaints about Avum to contact@avum.io. We will give a substantive written response to Consumer complaints within 30 days unless law requires sooner, and retain the complaint and response for three years as required by Hungarian law.

Payment, invoice, cancellation, and refund requests may also be submitted to Paddle using the contact method in your transaction confirmation or the Paddle buyer portal. The Provider will reasonably cooperate in resolving a billing complaint.

If a Consumer dispute cannot be resolved directly, a Hungarian Consumer may apply to the competent conciliation body. The competent body is:

A Consumer may also contact the consumer-protection authority competent for their residence or use the Hungarian National Trade and Consumer Protection Authority's guidance. These options do not prevent either party from pursuing a claim in court.

24. Governing law and courts

These Terms are governed by Hungarian and applicable EU law. If you are a Consumer, this does not deprive you of mandatory protections granted by the law of your country of habitual residence, and you may bring proceedings in any court available to you under mandatory consumer-jurisdiction rules. For Business Users, the competent courts in Hungary have exclusive jurisdiction, unless applicable law requires otherwise.

25. Changes to these Terms

We may update these Terms to reflect changes to the Service, pricing structure, providers, security practices, or law. We will post a new effective date and give at least 30 days' advance notice in a durable form of a material change affecting an existing paid subscription, unless an urgent legal or security reason permits shorter notice.

You may cancel before a material change takes effect. A change requiring express consent binds you only after you give that consent. Section 18 and mandatory law govern changes to the digital Service itself.

26. General provisions

If any provision is unenforceable, it will be limited or removed only to the extent necessary, and the remaining provisions will continue in effect. Failure to enforce a provision is not a waiver. These Terms, the checkout plan, and incorporated documents form the entire Service agreement without limiting Paddle or mandatory rights. Notices may be emailed to your registered address or displayed in the Service. Keep your address current. Questions may be sent to contact@avum.io.
