Privacy Policy

Last updated: 28 May 2026

V-Tune doesn't collect any of your data. No accounts, no analytics, no ads, and it doesn't phone home. Everything the app does happens on your device.

What V-Tune uses

Microphone access

V-Tune asks for permission to use your microphone so it can listen to the instrument you're tuning. The audio is processed in real time on your device to detect frequencies and drive the strobe display. None of this audio is recorded, stored, or transmitted anywhere. It exists in your device's memory only for the few milliseconds it takes to compute the next strobe frame, and is then discarded.

Local settings storage

Your preferences — selected scale, reference frequency, theme, settings panel state — are saved in your device's local storage so they persist between sessions. This data never leaves your device.

What V-Tune does not use

Children's privacy

V-Tune does not collect any personal information from anyone of any age, so there is no special handling for users under 13. The app is suitable for any user who can operate a touch screen.

Changes to this policy

If we ever change what V-Tune does with data (we don't plan to, but if this app ever gains a feature that requires it — say, syncing presets across devices), we'll update this policy and bump the date at the top. For material changes, a notice will appear in the app itself.
