HARF Privacy Policy.

Last updated: November 2026

Harf ("the app") is a Quran letter-pattern search app. 

This page explains what data is, and isn't, collected when you use it.

No accounts, no personal data collected by us

Harf has no sign-in, no user accounts, and no servers of its own. All Quran text and translation data ships inside the app and every search runs entirely on your device. Your searches, saved results, and settings are stored only in the app's local storage on your device — we never see them, and they are never sent anywhere.

Third-party services

Harf uses two third-party services, each covered by its own privacy policy:

Bullet list:

Google AdMob shows banner ads to free users. We request only non-personalized ads, so AdMob does not use your advertising identifier or activity history to target ads to you — it may still process basic technical data (such as device type and general region) needed to serve and measure any ad. See Google's Privacy Policy: https://policies.google.com/privacy

Apple's App Store (StoreKit) processes the optional one-time "Remove Ads" purchase. Payment details are handled entirely by Apple — Harf never sees or stores them. See Apple's Privacy Policy: https://www.apple.com/legal/privacy/

Children's privacy

Harf is a general-audience reference and study tool and does not knowingly collect personal information from anyone, including children.
