Who runs MET Gnome
Richard Demy.
What we keep
- Account: a name or made-up player name, email (none for players under 13), a scrambled password, instrument, birth month and year, and a parent's email for players under 18.
- Practice records: what you played, when, for how long, tempos, ratings, points and scores. For instrument playing this includes note by note pitch and timing results.
- Instrument recordings: only for adults, and for teens whose parent allowed it. Never for players under 13.
- A sung pass: one overall percentage, so it can count in the game. No recording and no notes.
- On your device: takes waiting to be sent, settings, and your own music pictures. These stay on the device.
- Cookies: one to keep you logged in, and one for a day after the birth month question.
We do not collect your location, contacts or photos. There is no chat between players and no public profile.
What we use it for
To run the practice coach and game: choosing music, measuring progress, points and streaks. Sign-in, password resets, and the emails you ask for. Keeping the service safe.
Who else can see it
- Other players can hear an instrument take only if the player allowed sharing. Takes have no name on them, and listeners hear only from the first note to the last. A player who joins the weekly race shows their name on it; the race is not offered under 13.
- A teacher you link to, with both of you agreeing, sees your practice records and takes kept for review.
- Companies that run the service for us: our web host and email delivery. Fonts and music software are served from our own site, so they learn nothing about you.
- AI tools: only adults who said yes have instrument takes studied this way. A minor's audio is never sent to one.
We do not sell personal information. There are no ads inside practice or the game, and no ad tracking. A labelled ad for a separate company appears on the public download page, and it uses no tracking.
How long we keep it
| What | How long |
|---|---|
| Most instrument recordings | 7 days, then deleted at midnight |
| Takes kept for a teacher | Up to 30 days |
| Takes being compared by listeners | Up to 14 days |
| The best takes of a piece, and takes high on a ladder | While they stay there, ending 730 days after the player's last visit |
| Practice records and account | Until the account is deleted |
| Under 13: a sign-up no parent answers | 14 days |
| Under 13: an account not used | 730 days |
We keep these so the practice coach can follow your progress, and so listeners can compare takes.
Children and teens
- Under 13: a parent approves by email before anything can be used, and sets the password. The player has a made-up name. Audio is never saved: a take plays back on the device and is gone.
- 13 to 17: a made-up name. Instrument takes are saved only if a parent allows it. Sharing is off until the teen turns it on.
- Parents can see what is kept, download it, stop further collection and delete the account at any time from the Parents page, with no password: we email a link. Approving does not mean agreeing to sharing with others; players under 13 are never shared.
If you believe a child under 13 is using MET Gnome without a parent's approval, please contact us and we will delete the account.
Your choices
In Profile you can change sharing, download everything we keep, and delete your account. A listener who hears something wrong can tap Report: the take is hidden from everyone until an adult checks it.
Keeping it safe
Passwords are stored scrambled. Recordings are served only to signed-in people allowed to hear them. Repeated login tries are blocked. Links we email work once and expire. We review these safeguards every year.
Changes
If this notice changes in a way that matters, we ask you to accept it again, and we tell parents.
