3. How We Use Your Data

4. Nickname and Leaderboard

NoteQuest includes a leaderboard that allows users to track and compare their performance.

To provide this feature, the nickname chosen by the user and their score may be displayed to other users within the application. Users are responsible for the content of their chosen nickname and should avoid including unnecessary personal information.

5. Firebase

NoteQuest uses Firebase services, provided by Google, for certain infrastructure and application features.

  • Firebase Authentication: used for account creation and authentication.
  • Cloud Firestore: used to store data related to accounts, progress, and performance.
  • Firebase Analytics: used for usage analysis.

Firebase Authentication may process information necessary for authentication and account management, including email address, authentication credentials, and certain technical information used for security and abuse prevention. The processing performed through Firebase services is also subject to Google's applicable policies and documentation.

6. Google Analytics for Firebase

NoteQuest uses Google Analytics for Firebase to understand how users interact with the application. Analytics may collect information related to usage events, interactions with features, and certain technical information.

NoteQuest does not use the user's email address as a User ID in Firebase Analytics.

7. Advertising

The free version of NoteQuest may display advertisements through Google AdMob. The use of AdMob may involve the processing of certain technical information and information related to the display and interaction with advertisements.

Because NoteQuest may be used by children and teenagers, the application implements mechanisms intended to comply with applicable advertising requirements for children and users whose age has not been determined.

8. Children and Teenagers

NoteQuest may be used by children and teenagers. The processing of personal data belonging to these users will be carried out in accordance with applicable laws and, in particular, with the best interests of the child or teenager.

The application also follows requirements applicable to applications distributed through Google Play that may be used by children, including rules related to advertising, identifiers, and third-party services.

9. Data Sharing

NoteQuest may share data with, or allow data to be processed by, service providers necessary to operate the application. The main third-party services currently used are:

  • Firebase Authentication: account authentication and management.
  • Cloud Firestore: application data storage.
  • Firebase Analytics: usage analysis.
  • Google AdMob: advertisement delivery.

NoteQuest does not sell users' personal data.

10. International Data Transfers

Some services used by NoteQuest are provided by companies that operate infrastructure outside Brazil. As a result, certain data may be stored or processed in other countries, depending on the infrastructure and services used. Where international transfers of personal data occur, NoteQuest will adopt the measures and mechanisms required by applicable law.

11. Security

We adopt technical and organizational measures designed to protect personal data against unauthorized access, loss, alteration, disclosure, or improper destruction. The infrastructure used by the application also benefits from security mechanisms provided by Firebase and Google services. Despite the measures adopted, no electronic system can guarantee absolute security against all existing risks.

12. Data Retention

Personal data will be retained for as long as necessary to provide NoteQuest features, maintain the user's account, comply with legal obligations, or exercise legitimate rights related to the service.

13. Account Deletion

Users may request deletion of their account through the functionality provided by NoteQuest or through the privacy contact channel.

Account deletion may result in the removal of data associated with the account, including registration information and progress data, subject to legal retention obligations and other circumstances permitted by law. Certain data may remain stored for the period necessary to comply with legal obligations, prevent fraud, maintain security, or exercise legal rights.
