Tone Generator: Sound & Sweep — Last updated: July 20, 2026
1. Overview
Tone Generator: Sound & Sweep ("the App") is a free Android app that generates audio test signals — sine, square, triangle and sawtooth tones from 1 Hz to 22 kHz, frequency sweeps, and white, pink and brown noise — for testing speakers and headphones and for sound masking. This Privacy Policy explains how we handle information when you use the App.
2. Information We Collect
The App does not collect, store, or transmit any personal information to our servers. It has no user accounts and no sign-up. There is no server-side communication other than loading advertisements (see Section 3). Your last-used frequency, waveform, channel, volume and preset are saved only on your device and never leave it.
3. Third-Party Services
The App uses the following third-party service:
- Google AdMob — for displaying advertisements. The App shows a banner, an app-open ad on launch, and occasional full-screen ads at natural break points (such as opening the preset library, switching modes, or when a sweep finishes) — never while you start or stop a tone or noise. AdMob may collect device identifiers (such as Advertising ID) and usage data to serve personalized or non-personalized ads. For more information, see the Google Privacy Policy.
4. Permissions
The App requests internet access only to load ads. It does not use or request access to your microphone, location, contacts, camera, photos, files, or notifications. The App only plays audio through your device output; it does not record any audio.
5. Data Storage
The App does not create user accounts and does not sync any data to the cloud. All your settings stay on your device. Uninstalling the App removes your local data and any cached AdMob data stored on the device.
6. Safe Listening
The App can produce loud and high-frequency sounds. Please keep the volume low, especially when using headphones, to protect your hearing. The App is a general-purpose audio tool and is not a medical device and is not intended to diagnose or treat any condition.
7. Children's Privacy
The App is suitable for general audiences and is not directed at children under the age of 13. We do not knowingly collect personal information from children.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
