Privacy Policy
Last updated: January 1, 2026 | Effective: January 1, 2026
CosmoTest (the "Service") respects your privacy and is committed to protecting your personal information.
1. No servers — we do not collect personal data directly
✅ The Service does not operate its own server or database.
Answers, birth dates, and results you enter in a test are never transmitted to the operator or stored anywhere outside your own device.
2. Use of browser localStorage
The Service uses your browser's localStorage for the following purpose only:
- Storing test configuration data (kept on your device only, never transmitted)
localStorage data is removed the moment you clear your browser data. The operator cannot access it.
3. Data collection by third-party services
The operator collects no data directly, but the following third-party services may collect information under their own policies.
Google Analytics — collects usage information to help us understand how the site is used.

X (Twitter) sharing — pressing the "Share on X" button on a result page opens the X share dialog. No communication with X occurs unless you press it.

X Privacy Policy
Cloudflare Pages (hosting) — the hosting platform that serves this site. It may collect access logs (IP address, browser information) under its own policy.

4. Cookies
The operator does not set cookies directly. However, third-party advertising services such as Google AdSense may use cookies.
- How to refuse cookies: block cookies in your browser settings, or turn off personalized ads at Google Ad Settings.
5. Your rights
Because the Service does not collect or hold personal information, there is no separate access or deletion request process. You can delete localStorage data yourself at any time.
- Chrome: Settings → Privacy and security → Delete browsing data
- Safari: Settings → Safari → Clear History and Website Data
