Privacy Policy
Last updated: June 20, 2026
Local-first learning data
Hafiza Web stores progress, bookmarks, settings, and review cards in your browser local storage. There are no Hafiza accounts and no Hafiza server database of your study data — your learning progress never leaves your device unless you export it yourself.
Backups
Exported backup files are created locally on your device. Import only backups you trust. Hafiza validates imported backup structure before replacing local progress.
Analytics
Hafiza uses Cloudflare Web Analytics, which is privacy-first: it is cookieless, collects only aggregate page metrics, and does not fingerprint or track individual visitors across sites. There are no advertising tags or social-embed trackers.
Payments
Hafiza is free to use. If you choose to buy Premium, checkout is handled by RevenueCat (Web Billing) and Stripe. Your card details are entered directly into their secure checkout and never touch Hafiza's own code. An anonymous RevenueCat purchase id is stored in this browser (hafiza.rc.appUserId) so your Premium access is recognised on this device — it is not linked to your identity by Hafiza.
