CartTally Privacy Policy
How Alexandr Korsak (Bitscorp) collects, uses, and stores data in the CartTally mobile app (co.bitscorp.carttally).
Privacy Policy
Effective date: 14 November 2026. I take your privacy seriously. This notice explains what CartTally stores on your device, what (if anything) leaves the device, and how to contact me.
Alexandr Korsak (Bitscorp), a self-employed professional (autónomo) in Spain, operates the mobile application CartTally (co.bitscorp.carttally). Bitscorp is a trading name, not a registered company. This page applies to CartTally on iOS and Android. The website https://bitscorp.co has a separate Privacy Policy and Terms and Conditions.
The app
CartTally keeps a running grocery total on your phone. You enter prices or point the camera at a shelf tag. Text recognition runs on the device. Trips, lists, and price history stay in a local database. There is no CartTally server.
Data stored on your device
- Stores, shopping trips, line items, price history, shopping lists, and settings in a local SQLite database.
- Price-tag text recognized on the device from the camera or from a photo you pick. The image and the recognized text are not sent to a cloud vision service.
Data that leaves your device
- Trips, prices, and lists are not uploaded to a Bitscorp server.
- A CSV leaves the device only when you choose to export it through the system share sheet.
- If you send feedback, your email app may include the app version and operating system in a message to alex@bitscorp.co.
- Purchase and subscription status are handled by Apple or Google and RevenueCat, as described below.
Permissions
- Camera (optional): to read a shelf tag on the device. You can type prices without the camera.
- Photo library (optional): to read a photo of a shelf tag already on this device.
You can change or withdraw permissions in the operating system settings.
Analytics and crash reporting
CartTally does not include a third-party analytics or crash-reporting SDK. I do not run Mixpanel, Google Analytics, Firebase, Sentry, or a similar product inside this app. The stores and RevenueCat may keep their own purchase or install records under their policies.
Third parties
I only involve the parties below for the purposes stated. Each has its own privacy policy.
- RevenueCat: To check and restore your Pro entitlement. RevenueCat receives purchase tokens, subscription status, and an anonymous app user identifier. It does not receive the journal, photos, files, or other content you keep in the app.
- Apple: If you buy or manage a subscription or a lifetime purchase on the App Store, Apple processes the payment. We do not receive your full payment card number.
- Google: If you buy or manage a subscription or a lifetime purchase on Google Play, Google processes the payment. We do not receive your full payment number.
Accounts, servers, and retention
No Bitscorp server. Price-tag text recognition and the trip ledger stay on the device.
CartTally does not require a Bitscorp account. Information stored only on your device remains there until you delete it in the app or uninstall the app. Purchase records are kept by Apple or Google and by RevenueCat for as long as they need them to provide the subscription. If you email me, I keep the message long enough to respond and then delete it when it is no longer needed.
Your rights
Because most CartTally content never leaves your device, the practical way to access or delete it is in the app, or by uninstalling the app (which removes local data). For any personal data I hold in email, or questions about purchase records, write to alex@bitscorp.co. If you live in the European Economic Area, the United Kingdom, or another region with similar rights, you may also request access, correction, deletion, or a restriction of processing of personal data I hold, and you may lodge a complaint with your local supervisory authority. In Spain that authority is the Agencia Española de Protección de Datos (AEPD).
International processing
I am based in Spain. Apple, Google, and RevenueCat may process purchase data in other countries. Their policies describe those transfers.
Changes to this policy
This Privacy Policy is effective as of 14 November 2026. I may update it from time to time. The current version will always be at https://bitscorp.co/carttally/privacy. Material changes will be reflected on this page, and I may also note them in the app.
