Privacy Policy
Last updated: October 21, 2026
This policy explains how the Ciclo de Áudio app (“App”), developed and published by Leonardo Alves, an individual, handles your data. Summary: the App does not collect, transmit or share personal data. Everything stays on your device.
1. Controller
Leonardo Alves (individual), Goiânia/GO, Brazil. Contact: [REDACTED].
2. Principle: privacy by default
The App works 100% offline, requires no account or login and uses no own or third-party servers. There is no usage analytics, advertising, tracking or third-party SDKs that collect data.
3. Data we do not collect
- Personal data (name, email, phone, etc.)
- The content of your audio
- Location
- Advertising identifiers and tracking data
- Usage, diagnostics or analytics data
- Contacts, photos and other files
4. Data stored only on your device
- Cycles: name, length, reminder time, progress and dates.
- Audio: recordings made in the App or files you import.
- Achievements and usage statistics.
- App preferences (for example, the tutorial and language).
This data is kept in a local database and in files in the App's storage. The developer has no access to it. It may be included in your device's own backups, according to your system settings and the platform's rules.
5. Permissions
- Microphone: used only to record audio inside the App. Recordings never leave the device.
- Notifications: for local daily reminders scheduled by the operating system, with no external push service.
- Files: to import an audio file you choose.
All permissions are optional and can be revoked in your device settings.
6. Sharing
We do not sell, share or transfer data, because we have no access to it.
7. Security
Your data is protected by the operating system's mechanisms. We recommend using a passcode or biometrics on your device.
8. Data deletion
You can delete cycles and audio inside the App. To delete everything, simply uninstall the App: local data is removed with it. There is no account or server data to delete.
9. Children
The App is not directed to children under 13 and collects no data from any user.
10. Your rights (LGPD and similar laws)
Under Brazil's General Data Protection Law (Law No. 13,709/2018) and similar laws, you have the right to confirmation, access, correction, deletion and information about data processing. Since the App does not process personal data outside your device, you exercise this control directly on the device. For any question or request, write to [REDACTED].
11. Changes
This policy may be updated. The current version and its date are always on this page.
