Privacy Policy

Cosinor.Online respects your privacy and is committed to protecting any personal data you may provide when using the application.

What Data We Collect

• No personal data is required to use the main features of this application.
• If you choose to register an account, we store your email address securely for login and verification purposes.
• You may optionally submit a short result-page rating and comment. The rating is linked only to the internal result and account identifiers needed to validate the submission; input and measured values are not copied into the feedback record. Ratings that indicate a possible issue, and comments, may also be sent to the site operator by email.
• Cosinor.Online does not currently use third-party advertising or analytics tracking.

Data Retention

Anonymous results are retained for no longer than 30 days. Results saved to a registered account are retained for no longer than 24 months after the account's last login. A new login renews that period. Advance email notices are sent before inactive-account results are deleted. Please download any results you wish to keep.

Cookies

This website uses only cookies required for essential functionality, including secure sessions and account login. Advertising cookies are not used.

Third-Party Services

The optional support link opens Buy Me a Coffee in a new browser tab. Cosinor.Online does not embed its payment form and does not receive or process your payment details. The external service's own privacy policy applies after you follow that link.

Data Security

All communication with the website is encrypted using SSL (HTTPS). We do not sell or share your data with any third parties.
