Numbrick privacy policy.
What the app collects, why, and the choices you have.
This privacy policy explains what information Numbrick (the app) collects, how RedFoxApps (we, us) uses it, and the choices you have. We publish this policy at a permanent address so app stores and users can always find it.
Who we are
Numbrick is published by RedFoxApps. For anything in this policy, contact us at [email protected].
Information we collect
Numbrick has no accounts, no ads, no analytics and no crash reporting. It works offline, and the only time it connects to the internet is to buy or restore Numbrick Pro.
- Data that stays on your device. Your calculations, paper tape history, memory and variables, settings, skin choice, guide progress and whether you own Pro are stored only on your device. We never receive them.
- Purchase data. Purchases are made through Google Play or the App Store. To check and restore Numbrick Pro, the app uses RevenueCat, which receives a random, anonymous app user ID, your purchase history for this app, and technical details needed to process the request, such as the app version, platform and store country. This is not linked to your name or email.
- Device features. The app uses vibration for key feedback and reads whether Low Power Mode or Battery Saver is on, to dim the solar strip. This stays on your device.
- Messages you send us. If you contact support, we keep your message and email address to reply.
Numbrick does not access your location, contacts, photos, camera or microphone.
How we use information
- To run the app and keep it working.
- To process, verify and restore purchases of Numbrick Pro.
- To answer support requests.
- To meet legal obligations.
Sharing with third parties
We use a payment provider (RevenueCat) and the app stores (Google Play and the App Store) to handle purchases. They process data on our behalf or under their own policies. When you share your paper tape, it goes only to the app you choose, and we do not receive it. We do not sell your personal information.
Children
Numbrick is not directed at children under 13, and we do not knowingly collect their personal information. If you believe a child has given us information, contact us and we will delete it.
How long we keep data
Data on your device stays until you clear it in the app, clear the app's data or uninstall it. Purchase records are kept as long as needed to restore your purchase and meet legal and tax obligations. Support messages are kept only as long as needed to help you.
Your choices and rights
You can clear your paper tape at any time, and uninstalling Numbrick removes everything it stored on your device. Depending on where you live, you may have the right to access, correct or delete your information. Because Numbrick has no accounts, we hold no information that identifies you, but email us and we will help with any request, including purchase records held by our payment provider.
Changes to this policy
