1. Data processed
No account is required, and the operator does not collect names, email addresses, precise location, photos or contacts. Referrals form one chain: each device may receive once and refer one next person once. The server processes a one-way hash of the OS device identifier, referral relationships, redemption state and the assigned official store code. The raw device identifier is not transmitted.
2. Data stored on the device
Favorites, browsing history, unit and appearance preferences, and the last store-verified special-thread entitlement are stored locally for app functionality and are not sent with searches.
3. Advertising and external links
The free and referral-code editions show non-personalized Google AdMob ads outside the Calculator. Google’s ad SDK may process device identifiers, IP address and ad interactions for ad delivery, fraud prevention and delivery measurement. Personalized behavioural ads are not requested. The one-time purchase removes banner ads. Optional sponsored product-search links may open Amazon; favorites, browsing history and search history are not sent to those links.
4. Update service
The app may contact Expo EAS Update. Expo may process OS data, a random installation token, IP address and update or crash diagnostics to deliver and stabilise updates.
5. Referral, promotion codes and purchases
The app sends its referral code to the operator server, which validates it and returns an available official Apple or Google store code. A referral code becomes used when the next device redeems it and cannot be reused by another device. That device then receives the right to pass one new code to one next person. The store processes redemption, store account and payment information; the operator does not receive store account or payment details.
6. Retention and deletion
Local data can be deleted in Settings or by removing the app. Referral hashes, relationships and redemption state are retained while the referral programme operates to prevent duplicate use. To request deletion, contact support with your own referral code. Store purchase records follow the store policy.
7. Contact
Privacy questions: contact support.
