Privacy of our apps

1. General information

This privacy policy describes how we manage information in our mobile applications available on Google Play. By using any of our apps, you accept the terms described in this document.

Our applications are designed with privacy by default: they do not require registration, do not create user profiles, and do not connect to our own servers to send data.

2. Data we DO NOT collect

Our applications do not collect, process, or store any of the following personal data:

• →Name, email address, phone number, or any identity information
• →Geolocation or IP address
• →Device identifiers (IMEI, IDFA, GAID, Android ID)
• →Usage history, clicks, or interactions within the app
• →Photos, camera, microphone, or multimedia content
• →Contacts, calendars, or device files
• →Financial or credit card information

3. Local operation

All functionality of our applications operates exclusively on your device. We do not have our own backend servers that receive, process, or store your information. Any data you generate within the app (settings, preferences, results) is stored only in your device's local storage and never leaves it.

4. Third‑party services

Some of our applications may integrate third‑party services that have their own privacy policies. These may include:

• →Google AdMob — to display advertisements. Google may collect certain identifiers according to its policy. You can review its policy at policies.google.com/privacy.
• →Google Play Services — for the proper functioning of the app on Android devices. Subject to Google's policy.
• →Firebase Crashlytics (if applicable) — for anonymous technical error reporting, without personally identifiable data.

When ads are used, the provider may collect data for ad personalisation. You can manage your preferences at google.com/settings/ads or at aboutads.info/choices.

5. Device permissions

Some apps may request operating system permissions to work properly. These permissions are used exclusively for the functionality described in the app and never to collect or transmit personal data . You can revoke any permission at any time from your device settings.

• →The permissions requested vary by app and are detailed in each application's store listing.
• →We never request permissions that are not strictly necessary for the app's functionality.

6. Minors

Our applications are not directed at children under 13 years of age (or under 16 in the European Union). Since we do not collect any personal data, there is no risk of collecting information from minors. If you are a parent or guardian and have concerns, you can contact us.

7. International transfers

Since we do not collect personal data ourselves, we do not carry out international data transfers. The integrated third‑party services (such as Google) may operate in multiple countries according to their own policies.

8. Your rights

Although we do not collect personal data, we recognise users' rights under applicable regulations (GDPR, CCPA, LGPD, and others). You have the right to:

• →Know what data of yours we have (in this case, none)
• →Request deletion of any data (not applicable, but you can contact us)
• →Opt out of personalised advertising through Google's control panels
• →Uninstall the app at any time, which removes all local data

9. Security

Since we do not transmit or store data on external servers, the risk of your information being exposed is minimal. The data that locally is protected by the security mechanisms of your device's operating system (Android or iOS).

10. Changes to this policy

We may update this privacy policy occasionally. We will notify you of significant changes through an update in the app's store listing or within the application itself. We recommend that you review this page periodically.

12. Account Deletion and Compliance with Google Play

If you decide to voluntarily register in our app, you will have full control over your account and your data at all times. As required by Google Play policies[reference:3], we offer users:

• →A clear option within the application itself to permanently delete your account and all associated data.
• →A functional web link where you can also request the deletion of your account and your data.

You can delete your account at any time, without needing to provide a reason. Once deleted, all information associated with your profile (username, rankings, statistics, and progress) will be permanently erased from our servers.[reference:4]

If you never created an account, we do not store any of your data. The decision to register is always yours, and we respect your right to change your mind and request the deletion of your information at any time.
