Data We Collect & Process

To provide core features, the site may store your preferences and usage state locally in your browser, such as language and spread selections.

  • Data is stored locally (e.g., LocalStorage/IndexedDB) and is not uploaded to our servers.
  • We do not create user accounts, require registration, or build server-side profiles.
  • No individual identification is performed beyond anonymous statistics by ad partners if necessary.

Local Storage & Retention

You can clear site data in your browser at any time. This removes local preferences and records. The site remains usable but personalization resets.

Cookies & Similar Technologies

We prefer local storage to minimize cookies; however, third parties (e.g., ad services) may use cookies or similar identifiers for essential functionality and analytics.

Advertising & Third Parties

We use Google ads to keep the site free. Third parties may use cookies or device info for anonymous statistics to improve ad relevance.

  • Google ads may set/read cookies for basic frequency capping and anonymous analytics.
  • You can restrict third‑party cookies in your browser or manage ad personalization in Google Ads settings.

Your Choices & Rights

  • Clear site data in your browser to remove locally stored settings and records.
  • Limit/disable third‑party cookies in your browser (may affect some features).
  • If you have privacy concerns, contact us via the method below.
