Privacy Policy

Last updated 27 July 2026. Applies to Reed for iPhone and iPad.

What stays on your device

• Practice history — every attempt, its four sub-scores and the measurements behind them, kept per instrument.
• Settings — your horn, tempo, tolerance, text size, and which screens you have unlocked.
• Your instrument check — the measured noise floor of your room and microphone, and, only if you switched on “Keep an audio recording”, the takes you recorded during that check.
• Imported songs — the transcribed notes, stored in concert pitch.
• Your Gemini API key, if you have entered one. It is stored in the iOS keychain rather than in preferences, because preferences are readable from an unencrypted device backup.

None of this is sent anywhere by Reed. It is included in your encrypted device backup if you use one, and it is removed when you delete the app.

The microphone

Reed asks for microphone access because measuring your playing is the entire point of the app. What it does with the audio:

• Practice audio is analysed frame by frame in memory and then dropped. It is never written to disk and never uploaded — not to us, not to Google, not to anyone.
• The one exception is the instrument check in Settings, and only with “Keep an audio recording” switched on. Those recordings are written to your device, stay there, and are deleted when you clear them or delete the app. You can share that bundle deliberately, which is the only way it ever leaves.

What leaves your device, and when

Reed talks to exactly one network endpoint, and it is silent unless you have asked for something: generativelanguage.googleapis.com, Google's Gemini API, used only when you have entered your own API key and asked for one of these things:

• Coach feedback, if you turn it on. What is sent is a digest of numbers: the exercise name, your horn, the tempo, the four sub-scores, aggregate measurements such as mean cents deviation and rise time, and a table of note names with their measured deviations. No audio, no name, no identifier, no location.
• Coach questions you type, together with that same digest.
• Song import: the recording or the sheet music you picked in the Songs tab is uploaded so the model can transcribe it. Only that file. The microphone is not connected to this path at all.
• The model list, so the app can show which Gemini models your key can use.

These requests go to Google under your own API key and are covered by Google's Gemini API terms and privacy policy. Reed neither keeps a copy nor sees the traffic. Leave the API key field empty and none of these requests are ever made: coaching falls back to a rule set that runs on the device.

With the API key field empty — which is how Reed arrives — the app makes no network requests at all.

What Reed does not do

• No analytics, crash reporting or usage tracking. Reed does not report what you tap, when you opened it or how often you practise.
• No advertising, and no advertising identifier.
• No third-party SDKs.
• No selling or sharing of data.
• No tracking as the App Store defines it: nothing is linked to your identity, and nothing is shared with anyone for advertising or measurement across other apps and websites.

Children

Reed is suitable for all ages, has no user accounts, no social features, no chat with other people and no purchases, and it collects nothing about anyone.

The exercises, the grading, the tuner and the player are available to a player of any age and send nothing anywhere. The AI coach and song import are optional and need a Gemini API key, which an adult would have to set up.

Your data, your call

Everything is in your hands, in Settings → Data: export your full history as CSV, or erase history, songs, calibration and the stored API key. Deleting the app removes all of it from the device.

Changes

If this policy changes, the updated version is published on this page with a new date, and the app's release notes will say so.
