Last updated: 2026-09-15
Who is the data controller
Sound Level Meter: Decibel is published by Raphael Goupille, under the name Fabula, reachable at fabula.app.contact@gmail.com.
Data collected
The app requires no account, no sign-up and no email address. Your progress and settings are stored on your device only. Only anonymous usage statistics are transmitted, detailed below.
Microphone
The app requests microphone access to measure sound level. The signal is analysed in real time on your device and is never saved as an audio file nor transmitted. Sessions you choose to record contain measurement values, not sound.
Usage measurement
The app uses Google Firebase Analytics to understand how it is used — screens opened, features used, crashes — and improve accordingly. Measurement is tied to an app instance identifier specific to your install, regenerated if you reinstall the app: it does not use Apple's advertising identifier (IDFA), does not follow you across apps and serves no advertising. Processing is carried out by Google LLC, which may host this data outside the European Union; its policy is available at policies.google.com. No data identifying you — name, email address, account — is collected, since the app asks for none.
Advertising
The app contains no advertising and no advertising trackers.
In-app purchases
The app offers optional in-app purchases. Payments are handled by Apple: the publisher receives no payment details.
Your rights
Under the GDPR you have rights of access, rectification, erasure, restriction, objection and portability (Articles 15 to 20), as well as the right to lodge a complaint with a supervisory authority (Article 77).
Because no data is tied to your identity on the publisher's side, these rights are exercised directly on your device: uninstalling the app deletes the data it stored. For any question, write to fabula.app.contact@gmail.com.
Changes
This policy may be updated. The date at the top of the page indicates the last revision.
