Guitar tuner with a step-by-step beginner guide, for iPhone

Privacy Policy

Last updated November 10, 2026

The short version

Easy Tune has no accounts, no ads and no tracking. It listens to your guitar only on your iPhone. Sound from the microphone is never recorded, saved or sent anywhere. We don't collect, sell or share any personal information.

This policy explains what the Easy Tune app ("the app", shown on the App Store as Easy Tune: Guitar Tuner) does with information. "We" means the makers of Easy Tune. You can reach us at support@maplewirelabs.com.

Microphone

The app asks for microphone access so it can hear your guitar and show whether each string is in tune. The sound is analyzed live, a few times per second, on your iPhone. It is never recorded, stored or sent to us or anyone else. The app listens only while it is open on your screen.

Voice guide and sounds

The voice guide and the guitar sounds are built into the app. They work offline and don't send anything over the internet.

Free trial and purchase

The free 7-day trial and the one-time unlock are handled by Apple through the App Store. Apple processes payment and we never see your name, Apple ID or payment details. The app only asks Apple whether this Apple ID has started the trial or owns the unlock. We don't use any third-party purchase or analytics service.

What stays on your iPhone

  • Your settings, such as sounds and voice on or off.
  • Whether you have finished the beginner guide.
  • The date your free trial started and whether the app is unlocked. These are kept in the iOS Keychain, so they may remain after you delete the app. This keeps the trial from restarting.

None of this is sent to us. We don't have a server.

What we don't do

  • No accounts or sign-in.
  • No advertising, analytics or tracking across apps and websites.
  • No collecting, selling or sharing of personal information.

Children

The app is suitable for all ages. It doesn't collect personal information from anyone, including children.

Changes and contact

If this policy changes, we'll update the date above. For questions, email support@maplewirelabs.com.

Terms of Use

Last updated November 10, 2026

Your use of the app is covered by Apple's Standard End User License Agreement, together with the terms below.

Free trial and one-time unlock

  • You can start a free 7-day trial from inside the app. Starting it is free and nothing is charged when it ends.
  • After the trial, the app's features stay locked until you buy the one-time unlock.
  • The unlock is a single payment, not a subscription. It is charged to your Apple ID when you confirm the purchase.
  • You can restore the unlock on any iPhone signed in with the same Apple ID, using Restore purchase.
  • Offer codes from us can be redeemed with Redeem code. Refunds are handled by Apple under its policies.

Tuning accuracy

The tuner is designed to be accurate, but readings depend on your microphone, background noise and your instrument. Use your own judgment, especially when tightening strings. Turn the pegs slowly. We aren't responsible for broken strings or damage to instruments.
