Privacy Policy — Numblr iOS App

The Numblr iOS app does not collect, store or transmit any personal data. It works fully offline. Your practice progress, mistakes and settings stay on your device.

None. The Numblr iOS app does not collect any personal information, identifiers, usage analytics, advertising data, location data or diagnostic data. We do not run analytics, crash reporters or advertising SDKs inside the app.

The app stores practice data locally on your device so the app can function. This data never leaves your device:

• Test results, mistakes and progress (kept in the app's local database)
• Daily streak and practice statistics
• App settings such as playback speed and preferred test types

If you delete the app, this data is removed with it.

All audio clips used in the app are bundled with the app itself. Playing a practice clip does not make a network request and does not reveal what you are practising to us or to any third party.

The Numblr iOS app does not require an account. There is no sign-up, no login and no email collection inside the app.

Optional Pro features are offered as in-app purchases. Payments are processed entirely by Apple through the App Store using StoreKit. We do not see, receive or store your payment details. Purchase and refund data is handled under Apple's privacy policy.

The Numblr iOS app does not share data with third parties, because it does not collect any data to share. The only third party involved is Apple, which handles app distribution and in-app purchases on our behalf.

The app is suitable for users of all ages (rated 4+). Because the app does not collect any personal information, it complies with the U.S. Children's Online Privacy Protection Act (COPPA) and similar regulations for children's privacy.

Because we do not collect or store any personal data about you, there is no personal data for us to access, export or delete. All your practice data lives on your device and is under your direct control — you can clear it by deleting the app.

This policy covers only the Numblr iOS app. The Numblr website (numblr.io) supports optional user accounts and payments and has its own data practices. If you also use the website, please refer to the website's own privacy information.

If we ever change what the iOS app does with data, we will update this page and revise the "Last updated" date above. Material changes will also be reflected in the App Store privacy details.
