The app doesn’t collect your personal data. Anyway, some data are saved on your device (user_id of Common Voice, selected language, validations and recordings number, and others data). You can clear them just Clear data of the app (but they are necessary to use Common Voice Android).
The app requires Storage and Microphone permissions when you use Speak section: because the app saves your recordings, and the app deletes automatically them (after sent to the Common Voice server). The app will ask permissions just when it needs of them.
If you turn on "Save logs to a file", the app requires Storage and will be save logs to files, but they won't contain your personal data. Read more about this in Saving the logs section (below).
The Experimental features could be unsafe and unstable, so pay attention if you use that option.
There are "two" versions: one for "Google Play Store" (GPS), and another for "F-Droid/GitHub" (FD-GH). In the first one the app show, sometimes a message "Review the app ... on Google Play Store", in the second one there is a button, in Settings, which permits you to "buy me a coffee". But the rest of the code is absolutely the same.
If you want additional information about the Policy privacy of Common Voice project, read the official doc by Mozilla.
All statistics are anonymous. CV Android nor Saverio Morelli collect your personal data. The statistics are useful just to see how many users use the app and how many contributions are done in the app.
You can disable Generic statistics always, in Settings. If you disable these statistics, you will not be in public statistics, but app sent anyway data to my database.
These statistics are absolutely anonymous. I don't collect your personal data. The first time (per day) you run the app, they send: unique_id, language, logged_status, version and status_statistics.

This option may slow down app performance, so turn on just when it's necessary.
You can turn on/off in Settings.
The file log is saved in an internal database, to a file and, also, it's sent to my website. In this way I can see fast issues and fix them. This is what I send to my website:
You can, anyway, save the file log on your device, (enable it in Settings > Advanced). To find the file you need to go to Internal storage > data > org.commonvoice.saverio > files > logs. Here there will be all log files (".txt"), that you could be attached to issues or reports.

This feature needs "Storage" permission.
Logs are saved in the common-voice-android.log file, so in that file will be all exception, warning or error messages. The file will contain max 1000 rows.
Your data, of course, will not be saved. The logs file will contain messages about the app, not about you.
This option is useful when you want to report a bug, so you can attach this file and the developer can see more details.
The app, from version 2.2, send to my website also the app usage. These information are absolutely anonymous and are useful to see how many users use, actually, the app and how many contributions are from the app.
You can disable App usage statistics in Settings. If you disable them, the app anyway will send query to my server, but the username is empty, in this way there is no way to know from who arrives statistics.
