These Terms of Service ("Terms") govern your use of the Syntara application and service. By registering and using Syntara, you confirm that you have read, understood and accepted all of the conditions below.

Registering for Syntara or using the service means you have entered into these Terms with us. If you do not agree with any of the conditions, do not use Syntara.

These Terms cover the Syntara mobile applications for iOS and Android, desktop clients, web interface and server infrastructure (collectively, the "Service").

5. Conduct and Objectionable Content

By using Syntara you agree not to post, transmit or distribute any content that:

• is pornographic, contains sexual violence or any other sexually exploitative material;
• contains child sexual abuse material (CSAM) — we report such cases to law-enforcement authorities;
• promotes violence, self-harm, suicide, mutilation, or threatens other people;

• infringes the intellectual-property rights of third parties (copyright, trademarks);

• contains personal data of third parties without their consent or otherwise violates applicable law.

6. User Content and Our Rights

Any messages, media or other materials you create, send or post on Syntara remain your property. To operate the Service, however, you grant Syntara a non-exclusive, royalty-free licence to store, transmit, display and process such content to the extent necessary to provide you with the Service.

Secret chat content is end-to-end encrypted (E2E) and is not accessible to us in decrypted form; the licence above applies only to the encrypted form of such content.

7. Moderation and Our Right to Act

Syntara reserves the right, at any time and without prior notice, to:

• remove any content that violates these Terms or applicable law;
• block or restrict the account of a user who breaches the rules;
• terminate an account for severe or repeated violations, including CSAM, incitement of violence and other serious breaches;
• transfer information about violations to law-enforcement authorities when legally required.

Moderation, blocking and removal decisions are taken by Syntara at its sole discretion with the interests of the community in mind.

8. Reports and Blocking Other Users

The app provides built-in tools to protect you from unwanted content and behaviour:

• Report content or a user: long-press on a message or use the menu on the other person’s profile. Report categories include spam, violence, pornography, CSAM, fraud, terrorism and others.
• Block a user: from the user’s profile or from the chat screen. Once you block a user, their messages are immediately removed from your feed and the conversation disappears from your chat list.
• Blocked list: managed in Settings → Privacy → Blocked Users.

We review all reports and take action within 24 hours of receipt. Reports flagged as urgent (CSAM, terrorism) are handled with priority.

9. Privacy

Processing of your personal data is governed by our Privacy Policy at /privacy, which is an integral part of these Terms.

10. Syntara Intellectual Property

All rights to the source code, design, logos, trademarks and other elements of the Service belong to Syntara and are protected by intellectual-property law. Using any Syntara element without written permission is prohibited.

11. Termination

You may stop using the Service at any time by deleting your account in Settings → Account → Delete Account.

We may suspend or terminate your access to the Service if you breach these Terms. Termination of access does not release you from obligations that arose prior to termination.

12. Disclaimer of Warranties

The Service is provided "as is" and "as available". To the extent permitted by applicable law, Syntara does not warrant that the Service will be uninterrupted, error-free or that it will meet your expectations.

13. Limitation of Liability

To the extent permitted by applicable law, Syntara is not liable for any indirect, incidental, punitive or consequential damages arising from your use of, or inability to use, the Service.

14. Governing Law and Dispute Resolution

These Terms are governed by the laws of the Russian Federation. Disputes arising under these Terms shall be resolved by the court at the place of Syntara’s registration, unless otherwise required by mandatory provisions of applicable law.

15. Changes to These Terms

We may update these Terms. For material changes, we will notify you in-app at least 7 days before the changes take effect. Continued use of the Service after such notice constitutes acceptance of the updated Terms.
