General Terms and Conditions

1. Scope and status of this document

Version: 2026.08.20. Effective date: 20 August 2026.

These General Terms and Conditions apply to the VOOVO website, web app, iOS and Android apps, and the learning services available through them.

These Terms form part of the contract between VOOVO and a natural person using the service in their own name. A separate contract may apply to schools, educational institutions, content creators and other business partners; that separate contract prevails where it differs from these Terms.

The language of the contract is Hungarian. This English text is a reference translation. If the texts differ, the Hungarian version prevails. VOOVO keeps the current and previous versions available on its website.

2. Service provider

Provider: Voovo Hungary Korlátolt Felelősségű Társaság (short name: Voovo Hungary Kft.).

Registered office and postal address: 2083 Solymár, Budai Nagy Antal utca 51., Hungary.

Company registration number: 13-09-216134. Tax number: 27478583-2-13. Representative: Hermán Benedek Zsombor.

Customer service and complaints: support@voovo.study. Telephone: +36 70 415 8036.

Website hosting provider: Vercel Inc., 440 N Barranca Avenue #4133, Covina, CA 91723, United States. The mobile apps and some service components use additional contracted infrastructure providers; the Privacy Notice explains their data-processing roles.

3. Definitions

VOOVO or Service means the VOOVO website, web app, mobile apps and the learning functions available through them.

User means a natural person who uses the Service. Consumer means a natural person acting outside their trade, profession or business.

User Content means any note, document, image, question, message, flashcard, exercise, course item or other data uploaded, created or shared by a User.

Subscription means access that renews automatically for the period shown at checkout. Lifetime Access means access for a one-time fee for the period and with the remedy defined in section 10.

4. Contract formation and electronic contracting

By registering or starting to use the Service, the User accepts the terms that apply to its use. For a paid plan, a contract requiring payment is formed when the User accepts the offer shown at checkout and payment succeeds.

Before purchase, the User can review and correct the information entered. Confirmation is sent to the registered or checkout email address, or appears in the relevant app-store account.

VOOVO records contract formation and the accepted Terms version electronically. The contract is not treated as an individually filed written contract unless the parties sign a separate written agreement. VOOVO has not agreed to be bound by a code of conduct.

The User must provide accurate and current information, protect login details and promptly report unauthorised account use.

5. Age, parents and school use

A User aged 16 or older may register independently. A User under 16 may use the Service only with permission from a parent or legal guardian, or through an invitation from a school or other educational institution.

Only an adult parent or legal guardian may make a purchase for a minor. A minor may not independently take on a payment obligation for which the law requires their legal representative's consent.

For school invitations, the institution's separate agreement may define which learning data and results a teacher or institution can see. The Privacy Notice and the institution's information explain the relevant data processing.

Some functions connected to external providers may have a higher age limit. VOOVO may restrict or disable such a function for minors.

6. Service content and technical requirements

VOOVO provides functions including flashcards, notes, courses, exercises, quizzes, learning paths, revision, sharing and AI-assisted learning tools. The exact contents and limits of each plan appear at checkout.

Use requires a compatible device, supported operating system or browser and an internet connection. The User bears these costs.

VOOVO does not promise a particular learning outcome, exam result or level of knowledge. The Service is a study aid and does not replace a teacher, official course material or professional advice.

7. User Content, sharing and rights

Ownership of User Content and the intellectual-property rights in it remain with the User or the original rightsholder.

The User grants VOOVO a non-exclusive, worldwide licence, limited to what is needed to operate the Service, to store, technically copy, transform, display and transmit User Content while the account exists and for any necessary backup or legal retention period. This licence does not allow VOOVO to use the content to train general AI models.

A User may upload and share only content for which they have the necessary rights and permission. Illegal, infringing, deceptive or harmful content, or content containing another person's unnecessary personal data, is prohibited.

When a sharing code or copy function is used, the recipient can create a separate copy. Later disabling the share can prevent new imports but does not automatically delete copies previously created by recipients.

Illegal content can be reported to support@voovo.study. VOOVO may restrict or remove content when required by law or needed to protect rights, security or these Terms; unless prohibited by law, VOOVO explains the reason and provides a way to challenge the decision.

8. AI-assisted functions

VOOVO clearly indicates when a User is interacting with an AI-assisted function. An answer, title, flashcard, exercise or other output may be inaccurate, incomplete or wrong. The User must verify important information.

VOOVO does not train AI models. Private prompts, uploads, chats and learning materials are sent to contracted AI providers only to provide the feature requested by the User.

VOOVO does not use this content for general model training and does not permit providers to use it for general model training. Any future training use would require separate, explicit consent.

The User must not enter unnecessary sensitive or confidential personal data. The Privacy Notice explains the processing and the contracted providers.

9. Prices, payment, invoices and app stores

Before the order, checkout shows the total price, currency, taxes, billing period, any trial and the plan contents. VOOVO provides an electronic invoice or other legally required receipt.

For web purchases, the contract is with VOOVO and card payments are handled by the contracted payment provider Stripe. VOOVO does not store full card details.

Purchases made through the Apple App Store or Google Play are handled by that store. The store's terms and mandatory consumer law govern charging, billing, cancellation and refunds. VOOVO does not provide a separate voluntary refund right beyond the rights supplied by the store.

Mandatory consumer rights remain unaffected, regardless of where the purchase was made.

10. Subscriptions, trials, cancellation and Lifetime Access

A Subscription renews automatically for the monthly or annual period shown at purchase, and the payment provider charges the next period until the User cancels. Cancellation takes effect at the end of the paid period unless the law or the app-store terms require earlier termination and a refund.

A web Subscription can be cancelled through the Stripe customer portal linked to the VOOVO account. An App Store or Google Play Subscription must be cancelled through that store's subscription controls. Uninstalling the app or deleting a VOOVO account does not by itself cancel a Subscription.

If checkout offers a trial, its length, the price after the trial and the cancellation deadline appear before purchase. If the User does not cancel by the deadline, the trial converts into the paid Subscription shown at checkout.

Lifetime Access continues while VOOVO operates and can legally provide that purchased offering. It is not a promise covering the unlimited lifetime of the User, the company or a particular piece of software.

If VOOVO permanently removes the offering purchased with Lifetime Access for business reasons, the User receives comparable replacement access or a fair partial refund that takes account of the original price and how long the offering was available. This does not limit any further remedy required by law.

11. Performance, availability and changes

The digital service becomes available after successful registration or payment at the time shown at checkout. VOOVO may temporarily limit access for planned maintenance, a security incident, an external provider failure or another unavoidable cause.

VOOVO may update the Service for security, legal, technical or development reasons. Before a material adverse change to a paid digital service supplied for an indefinite period, VOOVO gives the Consumer advance notice on a durable medium, explains the reason clearly and provides any termination right required by law, unless the unchanged service remains available without extra cost.

VOOVO may notify the User of necessary security and operating updates. The User is responsible for installing offered necessary updates within a reasonable time.

12. Consumer withdrawal and termination

As a general rule, a Consumer may withdraw from a distance contract without giving a reason within 14 days after contract formation, or terminate it under the law after service performance has started.

If the Consumer asks VOOVO to start the service before the 14-day period ends, the Consumer may have to pay the proportionate price of the service supplied before withdrawal or termination. For a service that has been fully performed, the right ends only after the Consumer's prior express request and acknowledgement that full performance removes that right.

For digital content not supplied on a physical medium, the right ends when performance starts only if the Consumer gave prior express consent, acknowledged the loss of the right and received confirmation from VOOVO.

The Consumer may send a withdrawal or termination statement to support@voovo.study or VOOVO's postal address, or use the model form in the Annex. Where the law requires it, the “Withdraw from the contract” function on the website may also be used. Sending the statement before the deadline is sufficient.

After a valid withdrawal, VOOVO refunds the amount due within the period and by the method required by law. Paid access covered by the refund may end. For App Store and Google Play purchases, the request must be submitted through the store under its terms.

VOOVO does not provide a separate voluntary or goodwill refund right beyond refunds required by law or the relevant app store.

13. Conformity and defective performance

VOOVO must supply the digital content and digital service in conformity with the contract, including the functionality, compatibility, access and updates promised at purchase.

For a defect, a Consumer may require VOOVO to bring the service into conformity. If this is impossible, disproportionate, not completed within a reasonable time or the defect is serious, the Consumer may seek a proportionate price reduction or end the contract under the conditions set by law.

The Consumer may report a defect to support@voovo.study with the account or purchase email, a description, the affected device and any available receipt. This does not restrict any mandatory conformity, warranty or other consumer rights.

14. Account restriction, termination and deletion

The User may request account deletion through the function in the app or at support@voovo.study. Deletion does not automatically cancel a Subscription managed by Apple, Google or another payment provider.

VOOVO may restrict or close an account for a serious or repeated breach, unpaid fees, fraud, a security risk, infringement of rights or a legal obligation. Unless law, security or the protection of others requires immediate action, VOOVO first warns the User and provides a reasonable chance to stop the breach.

Unless prohibited by law, VOOVO gives the reason for a restriction or closure. The User can request a review at support@voovo.study.

After account deletion, personal data and User Content are deleted or retained according to the Privacy Notice, backup periods and mandatory accounting, consumer-protection or other retention rules.

15. Liability

VOOVO is not responsible for a fault in the User's device, internet connection, an app store or another provider outside VOOVO's control, unless the law provides otherwise.

To the extent allowed by law, VOOVO is not responsible for the legality or accuracy of User Content or damage caused by relying on an unverified AI output.

Nothing in these Terms excludes or limits liability for intentional damage, a breach harming life, physical integrity or health, or any Consumer right that cannot legally be excluded or limited.

16. Complaints

The User may send a complaint to support@voovo.study or VOOVO's postal address. VOOVO handles an oral complaint immediately where possible and gives a reasoned written reply to a written complaint within 30 days after receipt.

VOOVO keeps the complaint record, or the written complaint and a copy of the reply, for the statutory three years. A rejection explains the reason and identifies available authority or conciliation procedures.

For consumer-protection matters, the Consumer may contact the government office competent for their residence. For an individual contract dispute, the Consumer may also contact the conciliation body competent for their residence or place of stay.

The body competent for VOOVO's registered office is the Pest County Conciliation Board (Pest Vármegyei Békéltető Testület). Office: 1055 Budapest, Balassi Bálint utca 25. IV/2. Postal address: 1364 Budapest, Pf. 81. Telephone: +36 1 792 7881. Email: pmbekelteto@pmkik.hu. Website: panaszrendezes.hu.

VOOVO cooperates in a conciliation procedure as required by law. VOOVO has not made a general submission declaration, meaning that it has not accepted the board's recommendation as binding in advance beyond cases made binding by law.

17. Changes to these Terms

VOOVO may change these Terms because of a change in law, a security requirement, a new or changed feature, a change of external provider or a business reason.

Before a material change adversely affects a paid period or an acquired right, VOOVO gives clear advance notice on a durable medium. Where required by law or the nature of the change, VOOVO asks for fresh acceptance or provides a right to terminate without a fee.

A new version does not apply retroactively to performance completed before the change. Its version number and effective date, and the previous text, remain available on the website.

18. Governing law, territorial availability and languages

Hungarian law governs these Terms. This choice does not remove mandatory protection under the law of a Consumer's habitual residence that cannot be excluded by agreement. A court with jurisdiction under applicable law may hear a dispute.

VOOVO's apps can be downloaded in countries where app stores make them available. Content published online by VOOVO's partners, including on YouTube, can be viewed globally. VOOVO does not currently select or pay a partner because the partner's viewers are mainly from a particular country or local-language market.

Global app availability and online access to partner content do not by themselves mean that VOOVO targets a particular foreign country. Before starting sales or advertising directed at a particular country or local-language market, VOOVO reviews the mandatory local consumer information and required translations.

Legal documents are available in Hungarian and English. The Hungarian version prevails if the texts differ, without limiting mandatory local language or consumer rules.

19. Final provisions

If a provision of these Terms is invalid or unenforceable, the remaining provisions stay effective. The mandatory rule of law and the lawful rule closest to the provision's commercial purpose replace the invalid provision.

A failure by VOOVO to exercise a right in one case does not waive that right. Any transfer of contractual rights and obligations must not reduce Consumer rights.

The Privacy Notice governs personal-data processing. The cookie notice governs cookies and similar technologies.
