2. Description of Service

Fair Divider is a free fair division calculator that produces envy-free allocations. The Service allows users to divide rent, expenses, goods, or other items among multiple participants. Available in standalone mode (single device), multi-device mode (multiple devices, real-time), and through native iOS and Android apps that connect to the same backend API.

3. No Warranties

The Service is provided "as is" without warranties of any kind. Specifically:

Results are approximate and are never mathematically exact.
Fair Divider does not guarantee that results will satisfy all participants or resolve disputes.
We do not guarantee uninterrupted access. Multi-device sessions require an active internet connection.

Not enter offensive, abusive, or illegal content in participant names or descriptions.
Not attempt to disrupt the Service through automated scripts, flooding, or attacks.
Not attempt to access other users' sessions without authorization.

5. Intellectual Property

The Fair Divider name, design, and software implementation are the property of the developer. The underlying mathematical principles are public domain mathematics.

6. Limitation of Liability

To the maximum extent permitted by law, Fair Divider shall not be liable for any indirect, incidental, special, or consequential damages arising from use of the Service, including financial decisions made based on results or disputes between participants. The Service is a mathematical tool, not legal or financial advice.

7. Session Data

Division sessions are temporary and automatically deleted after 7 days. Save or screenshot results if you need a permanent record.

8. Modifications

We reserve the right to modify, suspend, or discontinue the Service at any time without notice.

9. Changes to These Terms

We may update these Terms from time to time. Changes will be posted on this page. Continued use constitutes acceptance.
