In short: you can use the app without an account. If you create one, we keep the minimum: the email and name of your Google or Apple account and your progress along the path.
No ads, no analytics, no trackers, no profiling. We do not sell or share your data.
The microphone is used to hear your recorder: sound is analysed on your device; it is not recorded or sent anywhere.

| Data | Purpose | Legal basis |
|---|---|---|
| Email and name of your Google or Apple account | Identify you when you sign in. There is no password: you sign in with Google or Apple. With Apple you can hide your email (Apple gives us an address that forwards messages to you). | Performance of the service you request |
| Your progress: levels passed, stars and badges | Continue where you left off and have it on all your devices. | Performance of the service |
| If you buy Premium: that you have it, the date and the payment reference | Unlock it on all your devices and handle a refund. Card, Bizum or PayPal details are seen only by Stripe, never by us. If you buy inside the Google Play or App Store app, the store charges you and we only receive the purchase reference to verify it. | Performance of the purchase contract |
We do not collect location, contacts, photos, advertising identifiers or device data. No third-party cookies and no analytics.
You can use the app without an account (the first stage, the tuner and your own scores): your progress is stored only on your device. If you clear app or browser data, it is lost. Buying Premium does need an account, so it works on all your devices.
The app asks permission to use the microphone so it can hear the notes you play. Audio is processed instantly on your device to work out which note is sounding; it is not recorded, not stored and does not leave your device.
MusicXML files are read on your device. A MIDI file is sent to our conversion service to turn it into a score; it is used only for that and is not linked to your account.
If you turn it on, the app schedules a daily notification on your phone at the time you choose. It is a local notification on the device: it does not go through our servers.
Only what is essential: your signed-in session, your progress if you have no account, your settings (fingering, size…) and a copy of whether you have Premium so the app opens offline.
While you have an account. If you delete it, your progress and settings are erased. Backups are overwritten within 30 days at most.
You may ask us to access, correct, delete or export your data, or object to processing, by writing to info@clavedemi.com from your account email; we reply within 30 days. To delete your account you don't need to ask: do it in the app (how to delete your account). If you think we got it wrong you can complain to the Spanish Data Protection Agency (AEPD).
The app is made for families and teachers: children can use it with an adult. Accounts and purchases are for adults; we ask for no more data than listed above. If we find an account of a child under 14, we delete it.
If we change this policy we will update the date and tell you in the app. If we ever added ads or analytics — there are none today — it would be announced before switching them on.
