Privacy Policy

MaMa Sport Challenge (the “App”)

Last updated: 28 March 2026

What changed in this update: This policy was expanded and clarified to better describe how the App works in practice: local storage and backups; optional sharing and export; notifications and the visible training timer in the background; daily reminders (including rescheduling after device restart); the home screen widget; use of Google Play services (app updates, optional in-app review); and your choices and rights. We still do not operate our own backend servers to collect your training or progress data.

1. Scope

This policy describes how the App processes information when you use MaMa Sport Challenge on Android devices. By using the App, you acknowledge this policy.

2. Controller

The controller responsible for processing personal data in connection with the App is the operator of MaMa Sport Challenge. Contact details are provided in the App and/or on the Google Play store listing.

3. What data the App processes

The App processes the following categories of data only on your device (local storage, including app database and preferences):

We do not send this data to servers operated by us for storage or analytics. There is no user account or registration with us.

4. Purposes

Data is processed solely to provide the App’s functionality: run your challenge, show progress and statistics, send optional reminders you enable, show the optional widget, and respect your settings.

5. Storage, retention, and deletion

Data remains on your device until you uninstall the App or clear the App’s storage in Android settings. We do not retain copies on our own systems.

6. Device backup and transfer

Depending on your device and Android backup settings (e.g. Google backup), app data may be included in encrypted device backups managed by your device manufacturer or Google. That processing is governed by your device/Google settings and Google’s policies, not by servers we operate.

7. Permissions and on-device features

The App may request or use the following, only as needed for the features described:

Scheduling may use Android’s recommended background mechanisms (e.g. WorkManager). That runs on your device; we do not receive your training content from it.

8. Sharing, export, and screenshots

If you use Share, export, or similar features, you choose what to send and to which app (e.g. messages, email, files). The App may use Android’s secure file sharing (e.g. content provider) only to hand the file you chose to the receiving app. We do not control third-party apps you select.

9. Home screen widget

If you add the widget, the system displays summary information (e.g. today’s progress) from local data on your device. We do not receive widget data separately.

10. Third-party services (Google)

The App is distributed via Google Play. Installing or updating the App is subject to Google’s privacy policy. The App may use Google Play libraries for in-app update checks and the optional in-app review flow; those interactions are between your device and Google and are covered by Google’s policies. We do not sell your training or progress data and do not transmit it to third parties for their independent use.

11. No behavioural advertising by us

We do not use your data in the App to show third-party behavioural advertising, and we do not build advertising profiles from your training log on our own systems (we do not hold that log on our servers).

12. Children

The App is not directed at children under the age required by law in your country without parental involvement. If you believe a child has provided information in a way that concerns you, contact us via the store listing or in-App contact.

13. Your rights

Because core training data is stored locally, you can delete it by uninstalling the App or clearing App data. Depending on your region (e.g. EEA/UK), you may have additional rights regarding personal data; contact us using the details in the App or on the store listing. We will respond in line with applicable law.

14. Security

We design the App to keep processing on the device. No method of electronic storage is 100% secure; protect your device with a screen lock where appropriate.

15. Changes to this policy

We may update this policy. The “Last updated” date reflects the current version. Material changes may also be communicated via the store listing or in-App notice where appropriate. Continued use after updates constitutes acceptance unless applicable law requires different consent.

16. Contact

For privacy questions, use the contact information provided in the App or on the Google Play store page for MaMa Sport Challenge.
