Privacy Policy

1. Information we collect

This service collects and uses the following information.

• Local storage: Your font size setting, language setting, whether you dismissed the "Add to Home Screen" tip, and a note of which kind of ad to show (so the ad slot does not flicker on your next visit) are stored on your device. These are settings only; they contain nothing that identifies you and are never sent to a server.
• Browser cache (Service Worker): So that the app opens offline, the timetable and the pages themselves are stored on your device. Only publicly available content is stored — no personal information. You can remove it by clearing your browser's site data.
• Access analytics and security (Cloudflare): This service is delivered by Cloudflare, Inc. Its access analytics (Cloudflare Web Analytics) and bot protection may record information such as the pages you view, the referring page, your browser type and page load performance, as well as standard access logs (IP address, user agent, request path, etc.). This is used to understand how the service is used, keep it running reliably and prevent abuse, and is handled in accordance with Cloudflare's privacy policy.

2. Disclosure to third parties

We do not disclose collected information to third parties, except where required by law.

3. About cookies

This service's own features (font size, language settings, etc.) do not use cookies. They use storage on your device instead — localStorage for your settings, and the Service Worker cache for offline use. However, the ad delivery described below (Google AdSense and affiliate advertising) uses cookies via third-party ad providers, and Cloudflare's bot protection may set cookies for security purposes.

4. Advertising

This service uses the third-party ad service "Google AdSense (Google LLC)".

• Third-party vendors, including Google, may use cookies to serve ads based on a user's prior visits.
• Information collected: cookie data, access logs, browsing history, and similar data.
• You can opt out of personalized advertising via Google's Ads Settings.
• See Google's advertising policies for details.

* Google AdSense is based in the United States, and your information may be processed on servers located there.

This Service may also display affiliate advertising from A8.net and the Rakuten Affiliate programme instead of AdSense. If you click such a link and make a purchase, the operator receives a commission from the advertiser. This does not affect the price you pay, and the operator does not receive information that identifies you. These links may set cookies to measure referrals.

5. Data management

We manage collected information appropriately and work to prevent unauthorized access, loss, or leakage.

6. Voluntary support (donations)

If you make a voluntary contribution via the About page, payment is processed by Stripe, Inc. Card details etc. are managed by Stripe and are not retained by this Service.
