Terms of Use

Effective 2 August 2026

These terms are the agreement between you and Vidira for use of the Vidira app. By downloading or using Vidira, you agree to them. If you do not agree, please do not use the app.

1. The service

Vidira is a reading app for EPUB and PDF books, with optional AI features (“Dig deeper”, Ask, Quiz, Summarize, and coaching). Reading and basic AI features are free; some features require a Vidira Plus subscription.

2. Your account

Free reading needs no account. Vidira Plus requires signing in with Apple or Google. You are responsible for activity under your account and for keeping your sign‑in secure. You must be old enough to form a binding contract in your country to subscribe.

3. Vidira Plus subscriptions

• Vidira Plus is an auto‑renewable subscription offered on a monthly or annual basis.
• Payment is charged to your Apple ID at confirmation of purchase.
• The subscription automatically renews at the then‑current price unless you turn off auto‑renew at least 24 hours before the end of the current period.
• Your account is charged for renewal within 24 hours before the end of the current period.
• You can manage or cancel your subscription in your Apple ID Settings → Subscriptions after purchase.
• If a free trial is offered, any unused portion is forfeited when you purchase a subscription, where applicable.
• Prices are shown in the app before purchase and may vary by region. Payments are non‑refundable except as required by law or by Apple’s App Store policies.

4. Acceptable use

Use Vidira only for lawful purposes. Do not attempt to disrupt or reverse‑engineer the service, circumvent usage limits, or use it to infringe others’ rights. You are responsible for having the right to read and process any content you add to the app.

5. Your content

You keep all rights to the books, notes, and highlights you add. They stay on your device. When you use an AI feature, you grant us a limited licence to transmit the specific text or image you submit, and necessary context, to our AI providers solely to generate your response.

6. AI features and accuracy

7. Intellectual property

Vidira, its name, logo, and software are owned by us and protected by law. These terms do not grant you any right in our trademarks or software except to use the app as intended.

8. Disclaimers

The app is provided “as is” and “as available”, without warranties of any kind to the fullest extent permitted by law. We do not warrant that the service will be uninterrupted, error‑free, or that AI output will be accurate.

9. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, or consequential damages, or for loss of data, arising from your use of Vidira. Our total liability is limited to the amount you paid us in the 12 months before the claim.

10. Third‑party services

Vidira relies on Apple, Google, RevenueCat, and AI providers. Your use of those services is also subject to their terms and privacy policies.

11. Termination

You may stop using Vidira and delete your account at any time. We may suspend or end access if you materially breach these terms.

12. Apple App Store

This agreement is between you and Vidira only, not with Apple. Apple is not responsible for the app or its content, has no obligation to provide support or maintenance, and is not responsible for any product warranties or claims. Apple and its subsidiaries are third‑party beneficiaries of these terms and may enforce them against you.

13. Governing law

These terms are governed by the laws of the United Arab Emirates, without regard to conflict‑of‑laws rules, except where your local consumer‑protection law grants you mandatory rights.

14. Changes

We may update these terms; the effective date above will change and continued use means you accept the update.
