Privacy Policy — Void: Tuner & Learn

Last updated: March 2025 · Applies to iOS & Android

The short version

Void does not collect, store, transmit, or share any personal data — ever. Your microphone is used on-device only to detect pitch in real time. No audio is recorded. No account required. No tracking. No ads. Everything stays on your device.

01 / About Void

Void: Tuner & Learn is a music toolkit app developed by Core Tattva. It provides a chromatic tuner, strobe tuner, tone generator, interval training, pitch training, chord library for guitar and ukulele, and vocal pitch learning. The app uses your device's microphone solely to detect audio pitch locally in real time and does not require an internet connection for any of its core features.

02 / Data We Collect

We collect no data whatsoever. Void does not collect, process, or store any personal information, usage data, analytics, crash reports, device identifiers, or any other information from you or your device.

03 / Microphone Access

Void requests access to your device's microphone solely to detect the pitch of audio in real time for tuning and pitch training features. No audio is ever recorded, stored, or transmitted. All audio processing happens entirely on your device and is discarded immediately after pitch detection. You can revoke microphone access at any time in your device settings; non-microphone features (tone generator, chord library, interval exercises) will continue to work without it.

04 / Account & Login

Void requires no account, login, or sign-up of any kind. You can download and use the app immediately without providing any personal information.

05 / Internet Access

Void does not require an internet connection. All features — tuner, tone generator, training exercises, and chord library — function entirely offline. No data is transmitted to any server, third party, or external service at any time.

06 / Third-Party Services

Void does not integrate any third-party SDKs, analytics tools, advertising networks, crash-reporting services, or social login providers. There are no third parties who could receive any data from this app.

07 / Device Permissions

The only device permission Void requests is microphone access, used exclusively for real-time pitch detection as described above. Void does not request access to your camera, contacts, location, photos, notifications, or any other sensitive device permissions.

08 / Advertising

Void contains no advertising of any kind. There are no ads, no ad SDKs, and no ad-related data collection — ever.

09 / Children's Privacy

Because we collect no data from any users, Void is safe for users of all ages. We do not knowingly collect any information from children under 13 (or the applicable age of digital consent in your jurisdiction).

10 / Changes to This Policy

If we ever update this privacy policy, we will post the revised version here with an updated date. Any future version of Void that does collect data will clearly disclose what is collected and why, prior to any data being gathered.
