Terms & Conditions

1. Agreement and definitions

These Terms & Conditions ("Terms") govern access to and use of Avum Calendar Sync, the avum.io website, related applications, and support services (collectively, the "Service"). "Avum," "we," "us," and "our" mean Pentatope Technologies Kft. "User," "you," and "your" mean the person or entity accepting these Terms.

By creating an account, starting a trial, completing checkout, or using the Service, you confirm that you have read and agree to these Terms. If you do not agree, do not create an account, connect a calendar, or use the Service.

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. Provisions specifically addressed to Consumers or Business Users apply only to that group. Mandatory rights under applicable law always prevail over conflicting provisions of these Terms.

Our Privacy Policy explains how Avum handles personal data and forms part of the information provided with these Terms, but it is not a substitute for them.

2. Service provider and contact details

Hosting provider

3. Eligibility and authority

You may use the Service only if you have the legal capacity to enter into a binding agreement. If the law where you live requires a parent, guardian, or other legal representative to authorize your agreement, that person must review and accept these Terms and authorize your use of the Service. Avum is not directed to children and does not knowingly invite children to purchase subscriptions.

If you use the Service for an organization, you represent that you are authorized to accept these Terms for that organization and to connect the accounts and calendars involved. In that case, "you" includes the organization, and the organization is responsible for your use of the Service.

You must provide accurate and current registration, billing, and contact information and keep it updated. We may reject a registration or require reasonable verification where necessary to prevent fraud, trial abuse, unauthorized account access, or other misuse.

4. What Avum does

Avum connects supported Google and Microsoft accounts, lists calendars available through those accounts, and applies the synchronization rules you configure. Depending on your settings, the Service may read event information and create, copy, transform, update, or delete events in a destination calendar.

You decide which accounts and calendars to connect, which calendars act as sources and destinations, and which information is synchronized. By enabling a sync configuration, you instruct and authorize Avum to carry out the corresponding calendar operations, including changes and deletions needed to keep synchronized events consistent.

Available features, usage limits, connected-account limits, and sync-rule limits depend on the plan shown at checkout or in your account. Features may also depend on provider permissions, provider APIs, and the policies or technical settings of your employer, school, or other account administrator.

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 by multiple people. 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 natural person. For example, one person may connect their own personal, work, and education accounts where they are authorized to use each account. You may not use an individual Avum account to synchronize between provider accounts belonging to different people, even with their informal permission.

One individual subscription covers one Avum account only. A subscription may cover multiple Avum accounts or multiple people only where Avum expressly offers a family, business, or other multi-user plan whose published conditions permit it. The mention of such plans does not commit Avum to make them available.

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 settings, and our Privacy Policy. You may disconnect an account through Avum and may revoke access through Google or Microsoft. Revocation, expired credentials, provider restrictions, or administrator actions can interrupt synchronization.

Disconnecting an account or deleting a sync configuration does not necessarily remove event copies already written to another calendar. You are responsible for reviewing and, where appropriate, removing those copies.

7. Calendar information and your responsibilities

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

You are responsible for:

• having all rights, permissions, and lawful grounds needed for the calendar processing you direct;
• choosing sync settings appropriate for confidential information and for other people identified in events;
• reviewing new and changed sync configurations before relying on them;
• monitoring provider warnings and Avum error messages and promptly disabling an affected rule where continued synchronization could cause harm; and
• maintaining appropriate independent records or backups where loss of calendar information would have significant consequences.

Avum is a synchronization service, not an archival or backup service. 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

To enter into a subscription, you select a plan and monthly or annual billing, choose to start the trial, review the plan and future payment obligation in Paddle checkout, enter or confirm the requested details, and submit the transaction. You can review and correct input errors in the website and Paddle checkout before submitting. Paddle confirms the transaction electronically, and Avum provides the account-access steps by email.

The Avum agreement is concluded electronically in English. It is not treated as a separately signed written contract or filed by Avum as an individual paper instrument. Avum retains account records, and Paddle retains transaction records, as described in their respective notices and as required by law. The current Terms remain available on this page and can be saved or printed. Paddle may make its checkout and confirmation available in additional languages.

Before submitting, you can return to the relevant field or checkout step to correct an error. Afterward, you can update supported account or payment details through Avum or Paddle, or contact us for assistance. Avum has not subscribed to a separate voluntary code of conduct for the Service.

Paddle and recurring payments

Paddle is the Merchant of Record for all sales of Avum subscriptions.Paddle processes checkout, payment, invoicing, taxes, subscription renewals, cancellations, chargebacks, and payment refunds. When you complete a transaction, you also enter into Paddle's Buyer Terms. Those terms govern the purchase and payment relationship between you and Paddle; these Terms govern your account and use of Avum.

The plan, billing interval, price, currency, applicable taxes, trial end, and first charge are displayed at checkout. Monthly and annual subscriptions renew automatically for successive periods of the same length until cancelled. By starting a subscription, you authorize Paddle to charge the payment method provided at checkout when the trial ends and on each renewal date.

Prices may change for future billing periods. Paddle or Avum will give any notice required by law before a new price applies. If you do not accept a notified increase, you may cancel before it takes effect. Nothing in these Terms authorizes an unnotified charge or removes a cancellation right required by law.

9. The 30-day trial

Each eligible natural person may redeem one 30-calendar-day Avum trial in their lifetime. The trial begins immediately after successful Paddle checkout. Payment details are collected at checkout, but no subscription fee is charged during the trial.

Each email address may be associated with a trial only once in its lifetime. Creating or using additional email addresses, Avum accounts, identities, or payment methods to obtain another trial for the same person is prohibited. We may use reasonable account and transaction information to identify duplicate or abusive trial claims and may refuse or end an ineligible trial.

You may cancel without charge at any time before the trial ends through the Paddle buyer portal or another cancellation method made available to you. If you do not cancel in time, the monthly or annual plan you selected begins automatically, and Paddle charges the price shown at checkout.

10. Consumer withdrawal rights

Trial cancellation and statutory withdrawal are separate rights. If you are a Consumer in the European Union or another jurisdiction with a mandatory cooling-off right, you may have the right to withdraw from an online service or subscription contract without giving a reason within the period prescribed by law. In the EU, this period is ordinarily 14 days from conclusion of the relevant distance contract.

You request immediate access to Avum when you start the trial, including during any statutory withdrawal period. Access during the 30-day trial is free. Paddle's current Refund Policy also explains the withdrawal period it provides after a free trial ends and the procedure for requesting a refund.

To exercise a withdrawal or payment-refund right, submit an unequivocal request through the cancellation or support method in your Paddle transaction confirmation, the Paddle buyer portal, or email contact@avum.io. Include the email address used for the transaction and enough information to identify the subscription. If you contact Avum, we will assist with or forward the request to Paddle as appropriate.

Nothing in these Terms limits any mandatory right of withdrawal, refund, price reduction, termination, or conformity available to a Consumer.

11. Cancellation and refunds after the trial

You may cancel a paid subscription at any time through the Paddle buyer portal or another cancellation method Paddle makes available. 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.

Payments are not partially refunded merely because you stop using the Service or cancel before the end of a paid billing period. This does not affect refunds, withdrawals, remedies for a non-conforming digital service, or other rights required by law or provided under Paddle's applicable policies.

When paid access ends, active synchronization and paid features stop. Your Avum account and configuration may remain available for later reactivation, subject to our Privacy Policy and retention practices. You may request account deletion at any time. Ending an Avum subscription or account does not cancel unrelated Google or Microsoft services and does not automatically delete event copies stored by those providers.

Self-service account deletion

When you request account deletion, Avum immediately disables your sync rules, restricts normal account use, and begins best-effort removal of events Avum created. Deletion is scheduled after a seven-day grace period and may be canceled before the displayed deadline. Provider access problems can prevent removal of some Google or Microsoft event copies; after credentials are destroyed, you may need to remove those copies manually.

Avum protects renewal according to the live Paddle subscription state, preserves paid time, and cancels the subscription at the deletion deadline. Charges completed before the deletion request remain paid. A qualifying automatically collected recurring renewal captured while deletion is pending is refunded in full. Local account deletion is not postponed by an unresolved provider cleanup or past-due Paddle state.

12. Upgrades, downgrades, and feature limits

Plan changes take effect immediately after confirmation. Paddle calculates prorated charges or credits based on the precise time of the change, to the minute, and applies them to the subscription.

You may downgrade only when your active sync configurations and settings fit within the limits and features of the lower plan. If a rule uses a higher-tier feature, you must first disable the affected rule or remove or change the setting that is not included in the lower tier. Avum may block a downgrade until these conditions are satisfied.

If paid access ends instead of being downgraded, Avum may disable synchronization without first requiring you to change the affected rules.

13. Education discount

Where the education offer is enabled, Avum provides an education discount of at least 30% from the applicable standard subscription price. The exact percentage displayed in the Service or at checkout applies. The discount is conditional, personal, non-transferable, and may not be combined with another offer unless Avum expressly permits it.

To qualify and remain eligible, you must connect an account whose email domain matches Avum's currently configured education-domain list, connect a non-education personal account, and maintain at least one enabled sync configuration between the eligible education account and the personal account. You must be authorized to use both accounts. Domain matching indicates offer eligibility but is not an endorsement of or affiliation with the relevant institution.

If Avum detects that the qualifying education account or sync no longer satisfies these conditions, a three-calendar-month grace period begins on the date of detection. Avum will send two notices to your registered email address: an initial eligibility-loss notice and a reminder before the first non-discounted charge. Restoring eligibility during the grace period prevents removal of the discount.

If eligibility is not restored by the end of the grace period, the discount is removed and the standard price then applicable to your plan applies from the next charge. Failure to receive an email because your contact information is incorrect, your mailbox rejects the message, or a provider filters it does not extend the grace period. You may cancel before the standard price is charged.

Avum 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; or
• use the Service to harass, deceive, surveil, or cause harm to another person.

15. Account security

You are responsible for securing the email account, devices, provider accounts, and sessions used to access Avum. Notify us promptly if you suspect unauthorized access. Do not forward passwordless sign-in links or leave an authenticated session available to another person.

We may temporarily restrict access, revoke sessions, or require reconnection where reasonably necessary to protect you, other users, connected providers, or the Service.

16. Support

Support is available through contact@avum.io. We aim to respond within a reasonable time but do not promise a particular response or resolution time unless a separate written service-level agreement expressly applies.

A support request authorizes Avum personnel to inspect the account, configuration, connection status, execution history, and diagnostic information reasonably necessary to investigate that request. It is not blanket permission to browse calendar content. Human access to event content is governed by the scoped authorization and safeguards described in Section 7 of our Privacy Policy.

17. Avum intellectual property

Avum and its licensors own the Service, including its software, design, text, branding, documentation, and other materials, except for information supplied by users or third parties. Subject to these Terms and your applicable plan, Avum grants you a limited, non-exclusive, non-transferable, revocable right to access and use the Service during your account term for its intended purpose.

If you provide suggestions or feedback, you grant Avum 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

We use reasonable care and skill to provide the Service. However, synchronization can be delayed, interrupted, or affected by provider outages, rate limits, permission changes, network conditions, incorrect configuration, recurring-event complexity, or other technical conditions. No synchronization service can guarantee that every event change will be copied instantly or without error.

Google, Microsoft, Paddle, hosting providers, and other third parties operate independently of Avum. Their services, APIs, terms, and availability may change. We may adapt, suspend, or retire an affected Avum feature where reasonably necessary, including for security, legal compliance, provider compatibility, or service reliability.

We will give reasonable advance notice of a material reduction to paid functionality where practicable. If a material change prevents Avum from providing the core paid Service, Consumers retain all mandatory remedies, and other Users may cancel the affected subscription.

19. Suspension and termination

We may suspend or terminate access if you materially or repeatedly breach these Terms, fail to pay an amount when due, use the Service unlawfully, create a security or operational risk, abuse a trial or discount, 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 could expose a person, account, provider, or the Service to harm; undermine an investigation; or violate law or provider requirements.

You may stop using Avum at any time. Subscription cancellation, account deletion, and provider disconnection are separate actions. Provisions that by their nature should survive termination—including accrued payment obligations, intellectual-property protections, liability provisions, and dispute terms—continue to apply.

20. Legal conformity and disclaimers

Nothing in these Terms excludes a Consumer's 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.

Subject to those mandatory rights, Avum is provided on an "as available" basis. We do not promise that the Service will be uninterrupted, compatible with every calendar configuration, or free from every delay or error. Any description of planned or future functionality is informational and is not a commitment to release it.

Business Users are responsible for determining whether Avum meets their operational, regulatory, retention, confidentiality, and business-continuity requirements. No service-level commitment applies unless agreed separately in writing.

21. Liability

Liability that is never excluded

Nothing in these Terms excludes or limits liability where doing so would be unlawful, including liability for fraud or fraudulent misrepresentation, intentional misconduct, or death or personal injury caused by negligence, and any liability or consumer remedy that cannot legally be limited.

Consumers

Avum is responsible for loss a Consumer suffers that is a reasonably foreseeable result of our breach of these Terms or failure to use legally required care and skill. We are not responsible for loss caused by the Consumer's instructions, unauthorized use, failure to respond to a clear warning, or a third-party service outside our reasonable control, except to the extent Avum caused or contributed to that loss. Avum is not responsible to a Consumer for business losses arising from use outside their private purposes.

Business Users

To the fullest extent permitted by law, Avum is not liable to a Business User for indirect or consequential loss, loss of profit, revenue, anticipated savings, business opportunity, goodwill, or business data. Avum's aggregate liability to a Business User arising from or relating to the Service during any 12-month period is limited to the subscription fees paid or payable for that User's Avum account during the same period.

A Business User will indemnify Avum 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 Avum's own breach, negligence, or unlawful conduct.

22. Complaints and consumer dispute resolution

Send complaints about Avum to contact@avum.io or to our registered office. We will investigate written Consumer complaints and provide a substantive written response within 30 days, unless a shorter period is required by law. We retain the written complaint and our response for three years as required by Hungarian consumer-protection 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. Avum 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 body associated with Avum's registered office 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.

23. Governing law and courts

These Terms and the relationship between you and Avum are governed by the laws of Hungary and applicable European Union law, without regard to conflict-of-laws rules.

If you are a Consumer, this choice 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 courts having jurisdiction over Avum's registered office in Hungary have exclusive jurisdiction, unless applicable law requires otherwise.

24. 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 the revised Terms with a new effective date. For a material change affecting an existing paid subscription, we will ordinarily provide at least 30 days' advance notice by email or through the Service.

If you do not agree to a material change, you may cancel before it takes effect. Where law requires express consent, the change will not bind you without that consent. We may make an urgent change sooner where necessary to address a security threat, legal requirement, or provider restriction, while giving as much notice as reasonably practicable.

25. General provisions

Neither party is liable for delay or failure caused by events beyond its reasonable control, except that this does not excuse payment obligations already due or limit mandatory Consumer remedies.

You may not assign or transfer your Avum account or these Terms without our written consent. Avum may assign these Terms as part of a merger, reorganization, financing, or transfer of the Service, provided that doing so does not reduce mandatory Consumer rights.

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 plan information accepted at checkout, and any documents expressly incorporated by reference form the entire agreement about your use of Avum, without limiting rights arising under Paddle's Buyer Terms or mandatory law.

Notices may be sent to the email address registered to your account or displayed within the Service. You are responsible for keeping that address current. Questions about these Terms may be sent to contact@avum.io.
