EasyGuitarTube - Guitar Tuner
Last updated: September 19, 2026
EasyGuitarTube - Guitar Tuner (the “App”) is a guitar tuning app. The App processes the microphone audio needed for tuning locally on your device. We do not operate accounts, analytics, advertising, or third-party tracking in the App.
When you use a tuner screen, the App listens to your instrument in real time to estimate pitch. Audio is processed on your device and discarded immediately. It is not recorded, saved, or sent to 21Digital or another party.
The App stores your selected and custom tunings, instrument setups, tuning preferences, theme and gauge settings, and similar app preferences in local app storage. This information is not transmitted to us.
The camera is used only when you choose to scan a tuning-import QR code. Images are not saved or shared. If you explicitly create a diagnostic export, you choose where to save or share that file; EasyGuitarTube does not upload it to us.
EasyGuitarTube Pro is an optional one-time purchase processed by Google Play or the Apple App Store. The App receives an entitlement result so it can unlock Pro features. We do not receive or store your payment-card information or store-account credentials.
The App is not directed to children under 13, and we do not knowingly collect personal information from children.
We may update this policy and will revise the date above. For privacy questions, contact 21digitalai@gmail.com.
