In one sentence: MegaCarros requires no account, does not sell data and keeps your vehicle records in a local database on your phone.
1. Who we are
MegaCarros is an Android app for vehicle management. This Privacy Policy explains what information is processed when you use the app and this website, who it is shared with and what your rights are.
2. Records kept on your device
The data you enter about vehicles, fuel stops, charging sessions, expenses, maintenance and reminders is stored in a SQLite database on the device for display, calculations and reports. The app requires no account and does not automatically sync those records to a server.
This means that information does not pass through us. If the device is lost or damaged, or the app is uninstalled without a backup, records may be lost.
3. Usage analytics (Firebase Analytics)
The app uses Firebase Analytics. Usage events, such as creating and editing records, may include the type of operation, categories, values and internal identifiers, plus technical data collected by the service (for example, device model, Android version and installation identifiers).
These events are used to understand how the app works and improve the experience. Information such as the name you give your vehicle and backup file paths is not sent. This is not the same as automatically uploading the full records database.
4. External support chat
The Tawk.to chat is disabled by default. If you enable and open the chat, technical access data and the information you send in the conversation may be processed by the provider to handle your request. Avoid sharing unnecessary sensitive information.
5. Backups and sharing
Backups are created locally. When you choose to export or share, you decide where the file goes and are responsible for protecting it. The .megabackup format is compressed and has an integrity check, but it has no password or encryption.
6. Permissions and notifications
The app may request permission for notifications and for file access used in export or restore. You can manage these permissions in your device settings. Reminders are processed locally.
7. Retention and deletion
Local records remain until they are deleted in the app or along with its data. Uninstalling the app does not erase backups you already exported. Firebase events and Tawk.to conversations follow the retention rules of their respective providers.
8. Your rights (LGPD)
Under the Brazilian General Data Protection Law (Law No. 13,709/2018), you may:
- Access all records you entered at any time in the app.
- Correct any information directly on the editing screens.
- Delete individual records or all app data.
- Port your data by exporting a backup or a CSV report.
- Request information about data processed by external services.
To exercise rights related to data processed by Firebase or Tawk.to, use the support chat (which can be enabled in the settings) or the contact e-mail.
9. Security
Protect your device and your backup files. A backup integrity check does not prevent others from reading it: it is not a substitute for encryption. No storage method is entirely risk-free.
10. Changes to this policy
This policy may be updated. The date at the top indicates the current version. Relevant changes will be reflected on this page and, when necessary, in the app itself.
