Privacy Policy

Last updated: 2026-08-07

Durebak ("the Service") respects your privacy. This policy explains what we collect, use, and store. The Service is a static website you can use without any sign-up or login.

1. Information We Collect

• No personal data collected directly: the Service does not collect names, emails, phone numbers, or other identifying information.
• Browser local storage: numbers you save with "Saved records" or "My numbers" are stored only in your browser's localStorage and are never sent to or collected by our servers. They are removed when you delete them or clear your browser storage.

2. Cookies and Advertising

The Service may display third-party ads such as Google AdSense in the future. Ad providers may use cookies to serve interest-based ads, governed by their own privacy policies. You can manage personalized ads in your browser settings or via Google Ads Settings.

3. Analytics

We use Cloudflare Web Analytics (cookieless, anonymous visitor statistics) to improve the Service. Only anonymized usage metrics (visits, time on page) are processed, without identifying individuals.

4. Third-Party Sharing

The Service does not sell or rent your personal information to third parties.

Some features work by having your browser request data directly from outside providers. Winning-number data and the weather lookup on the /unchigi/ page (Korean only) work this way, and connection details (such as your IP address) may reach those providers in the process. Winning-number data sources are listed on the About page, and weather comes from Open-Meteo. What those providers do with the information is governed by their own privacy policies.

5. Data Retention and Deletion

Saved records exist only on your device and are under your control. The Service does not store user data on any server.

6. Contact

For questions about this policy, use the contact address on the About page.

If this policy changes, we will post the update here along with the revision date.
