Terms of Service — Clarinu

Last updated: 12.08.2026

Please read these Terms of Service ("Terms") carefully before using Clarinu ("the App"), operated by Mariusz Szyszka ("we", "us"). By creating an account or using the App, you agree to these Terms.

1. Eligibility

Clarinu is intended primarily for high school students. If you are under the age of majority in your jurisdiction, you confirm that you have any consent required under applicable local law to use the App (for example, parental or guardian consent where required). If you are using the App on behalf of a school or institution, you confirm you are authorized to do so.

2. Your account

• You are responsible for keeping your login credentials secure and for all activity under your account.
• You may use Clarinu without an account ("guest mode"); in that case, your data is stored only on your device and is not backed up unless you create an account.
• You may delete your account at any time from Settings. This will permanently remove your account data from our servers, as described in our Privacy Policy.

3. Use of the App

You agree to use Clarinu only for its intended purpose — planning and tracking your own studying. You agree not to:

• Use the App to store or transmit unlawful, harmful, or abusive content
• Attempt to gain unauthorized access to other users' accounts or data
• Interfere with or disrupt the App's infrastructure (e.g. automated bulk data submission, attempts to bypass security measures)
• Reverse-engineer, decompile, or attempt to extract the source code of the App, except as permitted by applicable law
• Use the App in any way that violates applicable laws or regulations

We may suspend or terminate accounts that violate these Terms.

4. Subscriptions and payments

At the time of writing, all features of Clarinu are available free of charge. If we introduce paid subscription features in the future, additional terms describing pricing, billing, renewal, and cancellation will be presented to you before you are charged, and this section will be updated accordingly.

5. Content and data you provide

You retain ownership of the study data you enter into Clarinu (e.g. subjects, exam details, notes). By using the App, you grant us a limited license to store, process, and display that data back to you as part of providing the App's features, as described in our Privacy Policy.

6. Intellectual property

The App, including its design, branding, and underlying software, is owned by us or our licensors and is protected by intellectual property laws. These Terms do not grant you any rights to our trademarks, logos, or brand assets.

7. Disclaimers

Clarinu helps you plan and track studying, but does not guarantee academic outcomes such as improved grades or exam results. The App's study plan is generated by an automated, rules-based system and is provided as a planning aid, not professional educational or academic advice.

The App is provided "as is" and "as available," without warranties of any kind, to the maximum extent permitted by law.

8. Limitation of liability

To the maximum extent permitted by applicable law, we will not be liable for any indirect, incidental, or consequential damages arising from your use of the App. Nothing in these Terms limits any liability that cannot be limited under applicable law.

9. Termination

You may stop using the App and delete your account at any time. We may suspend or terminate your access to the App if you violate these Terms or if we discontinue the App, with notice where reasonably possible.

10. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will notify you through the App or by other reasonable means before the changes take effect. Continued use of the App after changes take effect constitutes acceptance of the updated Terms.

11. Governing law

These Terms shall be governed by and construed in accordance with the laws of Poland, without giving effect to any principles of conflicts of law.
