Privacy Policy

Last updated 19 August 2026

GRANULA is an instrument. It records sound, granulates it and plays it back. This policy says what leaves your device when it does, and what happens to it afterwards. It covers the GRANULA iOS app and this web version, which share one account and one store.

What is collected

• Your email address, when you create an account. Signing in with Apple gives us whichever address you chose to share, including a relay address if you hid yours; Google or an email link gives us the address you used.
• Your recordings and imported audio, with the name and length of each, once you are signed in. These are the sounds you make or bring in yourself.
• Your subscription status: whether an account is free or subscribed, when its subscription runs to, and how many samples a free account has used. Apple tells us that a purchase happened. Apple does not pass on your payment details, and we never see them.

That is the whole list. There is no analytics package, no advertising, no third-party trackers, no location, no contacts, no identifiers collected for tracking, and no profile built about you.

The microphone

The microphone is opened only to record, and only while a recording is running. Nothing is captured in the background, and what it hears is never sent anywhere unless you keep the take — at which point it becomes one of your samples and is treated as one.

Where it is kept

• On your device. Every sample is written locally first and the instrument plays from that copy. Recording, granulating and playing never need the network.
• Supabase holds the account: your email address, the index of your recordings, and your subscription row. Access is scoped to the account — the database will not return another account's rows.
• Cloudflare R2 holds the audio itself, in a folder derived from your account identifier. A request can name a recording but never a user, so there is none it can make that reaches somebody else's audio.
• Apple takes the payment and tells our server the purchase is real, so a subscription is verified rather than taken on the app's word.

Those providers run in regions that may be outside your own country.

What it is used for

To sign you in, to keep your samples where you left them, to move them between your devices, and to know whether the account is subscribed. Nothing is sold, rented or shared for advertising, and nothing is used to train anything.

Deleting things

• A sample: open the sample list, tap ··· beside it and delete. It goes from the device and from the account.
• The account and everything in it: write to serezhaok@gmail.com from the address you signed in with. The account, the index and the stored audio are deleted within 30 days, and the mail is answered when it is done.

Signing out leaves samples on the device but hides them: a recording belongs to the account that made it, and another account signing in on the same device does not see it.

How long it is kept

Samples stay until you delete them or delete the account. Subscription records are kept while the subscription is live, and afterwards for as long as Apple's own records and tax rules require.

Children

GRANULA is not directed at children under 13, and accounts are not knowingly created for them.

Your rights

You may ask for a copy of what is held about you, ask for it to be corrected, or ask for it to be deleted, at the address below. If you are in the UK, the EU or anywhere with data protection law of its own, those rights are yours under it, and you may complain to your local authority.

Changes

If this policy changes the date at the top changes with it, and a material change is announced in the app before it takes effect.
