Terms of Service

1. Acceptance

By creating an account or using Zenith (“the Service”), you agree to these Terms of Service. If you do not agree, do not use the Service.

2. Description of service

Zenith is an AI-powered learning platform offering spaced repetition flashcards, language conversation practice, and personalised study planning. Features vary by plan (Free and Pro).

3. Account

• You must provide accurate information when creating an account.
• You are responsible for maintaining the security of your account credentials.
• You must be at least 13 years old to use the Service.
• One account per person. Do not share your account.

4. Free and Pro plans

• Free plan: up to 200 flashcards and 3 AI card generations per month.
• Pro plan: unlimited flashcards, 100 AI generations per month, and access to premium features.
• Pricing is displayed at checkout and may change with 30 days' notice.

5. Acceptable use

You may not use the Service to:

• Violate any applicable law or regulation
• Upload or generate harmful, abusive, or illegal content
• Attempt to reverse-engineer, scrape, or overload the platform
• Share your account credentials with others

6. Your content

You retain ownership of content you create (flashcards, decks, notes). You grant Zenith a limited licence to store and process that content solely to provide the Service. We do not use your content to train AI models.

7. Disclaimers and limitation of liability

The Service is provided “as is” without warranties of any kind. To the maximum extent permitted by law, Zenith is not liable for indirect, incidental, or consequential damages arising from your use of the Service.

8. Termination

You may delete your account at any time. We may suspend or terminate accounts that violate these terms. On termination, your data is deleted per our Privacy Policy.

Inactive accounts

If you do not sign in for 18 consecutive months, we will delete your account and the data in it — including your decks, cards, study history, reading history and progress. This is not a penalty: we do not keep personal data longer than we have a reason to.

Before that happens we email your registered address three times over 30 days— 30, 14 and 3 days before the deletion date — telling you the exact date and how to stop it. Signing in cancels the deletionand resets the 18-month clock, as does clicking the “keep my account” link in any of those emails. Either one is enough, and both take one click.

So that these warnings reach you, please keep a working email address on your account. You can change it at any time in Settings, and you can export everything we hold at any time from the same page.

We will never delete an account this way while it has anything of value attached to it. Accounts with an active, paused or Lifetime plan, accounts inside a payment grace period or a period you have already paid for, and accounts holding unspent AI credits are all exempt, however long they stay unused.

9. Changes to these terms

We may update these terms from time to time. Material changes will be communicated by email or a prominent notice on the platform at least 14 days before taking effect.

10. Governing law

These terms are governed by Danish law. Any disputes shall be resolved in the courts of Denmark.
