- Browser type and version
- Device type (mobile / desktop)
- Pages visited and time spent

b) Analytics (Google Analytics)
We use Google Analytics 4 to understand how visitors use the site. Google Analytics uses cookies and collects aggregated, anonymised usage statistics. Your IP address is anonymised before storage. You can opt out using the Google Analytics Opt-out Browser Add-on.
c) Advertising (Google AdSense)
We display advertisements served by Google AdSense (publisher ID: ca-pub-9381802263449755). Google uses cookies and similar technologies to serve personalised or context-based ads based on your prior visits to this site and other sites. You can manage ad personalisation preferences at adssettings.google.com.
d) Local storage & service worker
The site is a Progressive Web App (PWA). We store user preferences (language selection, notification settings) in your browser's localStorage. No personal data is sent to our servers via localStorage. A service worker is used solely for offline caching of static assets.
e) Location (prayer times)
If you grant location permission for city-based prayer time lookup, your approximate coordinates are used only in-browser to select the nearest city. Location data is never transmitted to or stored on our servers.
