Fretly — Privacy Policy

Last updated: 2 October 2026

Fretly has no account, no sign-up, and no server of its own. Your songs, your progress, and your microphone audio stay on your device. The only data that leaves your device is what Google's advertising service needs to show ads in the free version, described below. Fretly Pro removes ads entirely.

What Fretly does not do

• No user accounts and no sign-in.
• No analytics or crash-reporting services.
• Fretly has no server of its own and uploads none of your files or audio.

Advertising

The free version of Fretly shows a full-screen ad, at most once every few minutes, when you open a song you imported yourself. Built-in exercises never show ads, ads never appear while you are playing, and people who own Fretly Pro never see ads.

Ads are provided by Google AdMob. To show and measure ads, the Google Mobile Ads SDK collects and shares with Google your device's advertising ID, approximate location derived from your IP address, and information about your device and how you interact with ads. Google's use of this data is described in How Google uses information from sites or apps that use its services and in Google's Privacy Policy.

• If you are in the European Economic Area, the UK, or Switzerland, Fretly asks for your consent before any personalised ads are shown, and you can change your choice at any time from Privacy settings at the bottom of the Library.
• On any Android device you can reset or delete your advertising ID, or opt out of ad personalisation, in your device's Settings → Google → Ads (or Privacy → Ads).
• Buying Fretly Pro turns ads off completely.

Microphone

Fretly asks for microphone access for two features: the tuner, and the practice mode that listens while you play.

• Audio is analysed in real time on your device, in short fragments, purely to estimate the pitch you are playing.
• Nothing is recorded. No audio file is created, saved, or sent. Each fragment is discarded immediately after its pitch is measured.
• The microphone is only active while the tuner screen is open, or while you have turned the listening mode on. It is released as soon as you leave.
• You can refuse the permission. Everything else in Fretly keeps working.

Your files

You choose which Guitar Pro or MusicXML files to open. Fretly copies them into its own private storage on your device so it can open them again later. These files never leave your device, and Fretly does not upload, index, host, or share them.

Fretly does not provide or distribute any tablature. It only opens files you already have.

Purchases

Fretly Pro is a one-time purchase handled entirely by Google Play Billing. Fretly never sees your payment details. It only asks Google Play whether this Google account owns the product, so it knows whether to unlock the Pro features. Google's handling of that transaction is covered by Google's Privacy Policy.

Data stored on your device

Fretly keeps a small amount of information locally so the app is useful between sessions: your song list, the bar you last stopped on, your favourites, and your chosen tuning. This never leaves your device, and uninstalling Fretly removes it.

Children

Fretly is a music practice tool and is not directed at children under 13. Fretly itself collects no personal data from anyone; the advertising data described above is handled by Google AdMob under Google's policies.

Changes

If a future version of Fretly changes what is collected, this page will be updated before that version is released.
