Terms of Use

Effective 15 November 2026

These terms apply to the Tralle apps for iOS, Android and the web (together, “Tralle”), operated by Denis Makarov (“we”, “us”). By using Tralle you agree to them. If you do not agree, please do not use Tralle.

1. Who can use Tralle

You must be at least 13 years old, or the minimum age in your country, to use Tralle. If you are under the age of majority, you need permission from a parent or guardian.

2. The service

Tralle translates and explains words and texts, keeps them in your Library, and turns them into lessons and spaced reviews. Some content is produced automatically by machine translation and artificial intelligence.

3. Your account

You can use Tralle without an account or sign in with Google or an email code. Keep access to your sign-in method secure; you are responsible for what happens in your account. One account is for one person.

4. Your content

You keep all rights to the texts and notes you add. You give us permission to store, process and show them, and to send them to our service providers, only as needed to run Tralle for you, as described in the Privacy Policy. This permission ends when you delete the content or your account, except for copies kept in backups for a short time.

Only add content you have the right to use, and do not add other people's personal data without permission.

5. Acceptable use

Do not:

6. Third-party content

Dictionary content comes from Wiktionary contributors and is available under the Creative Commons Attribution-ShareAlike 4.0 licence and the GNU Free Documentation License; see Settings › About › Sources and licenses in the app. Machine translations are provided by Google Translate.

7. Paid features

Tralle is currently free. If we introduce paid features, we will describe them before you buy. Purchases in the iOS and Android apps are handled by Apple or Google under their terms, including their refund rules.

8. Ending your use

You can stop using Tralle and delete your account at any time in the app. We may suspend or close an account that seriously or repeatedly breaks these terms, or if the law requires it. If we stop offering Tralle, we will give reasonable notice where we can.

9. Disclaimers and liability

Tralle is provided “as is” and “as available”. To the extent the law allows, we make no promise that it will be error-free or always available, and we are not liable for indirect or consequential losses, or for decisions you make based on automatic translations or explanations.

Nothing in these terms limits liability that cannot be limited by law, or your rights as a consumer under the law of the country where you live.

10. App stores

If you downloaded Tralle from the Apple App Store, Apple's Licensed Application End User License Agreement also applies. Apple and Google are not responsible for Tralle or its support.

11. Changes to these terms

We may update these terms. We will change the date at the top and, for significant changes, tell you in the app before they take effect. If you keep using Tralle after that, the new terms apply.

12. Governing law

These terms are governed by the law of Spain. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring a claim in its courts.
