Privacy Policy

Maccu is a family sketchbook. You photograph a drawing, keep it in a notebook, and watch a childhood of pictures grow. This policy explains what we collect to make that work, where it lives, who helps us run it, and the choices you have.

We do not sell personal data. We do not show ads. We do not use children's art to train models. Drawings stay on your device unless you share them or turn on a Premium backup to your own iCloud or Google Drive.

Questions: hello@maccu.app.

Who Maccu is for

Maccu is for parents and other grown-ups who look after a child's art. The account, purchases, backups, and family profiles live in the Grown-up corner. Children do not create their own Maccu accounts.

If you add a child's name, age, photo, or drawings, please do so only for children you are allowed to represent.

Information we keep

Your account

Signing in is required after the short introduction. You can use Sign in with Apple, Google, or an email sign-in link. We receive what those services provide so we can create and recognise your account: an account identifier, usually an email address, and on the first Apple sign-in the name you choose to share.

Sign-in sessions are kept in your device's secure storage (the iOS Keychain or Android's equivalent). Account records are held by our authentication provider, Supabase.

Family profiles

You can create a profile for a child: a name, an optional age (stored as a birth year), and an avatar, either a colour character or a photo you choose. We also store which profile is currently selected. Free Maccu includes one child profile; Maccu Premium removes that limit.

Profile details sync with your signed-in account so they follow you to a new device. Avatar photos are stored privately with that account. Drawings are not stored in this profile database.

Drawings and photos

Maccu uses the camera when you photograph a drawing, and your photo library when you pick an existing photo or a profile picture. Processing happens on your device: Maccu finds the drawing, tidies the scan, and saves a sketchbook page. There is no cloud vision service and no AI model training.

Saved pages, the original photo each page was made from, and notebook choices such as which sketchbook design you picked are kept in Maccu's storage on your phone or tablet.

Preferences

Your language, whether you have finished the introduction, backup choices, and similar settings stay on the device.

Purchases

Maccu Premium is an auto-renewing subscription sold through the Apple App Store or Google Play. We use RevenueCat to know whether your account has Premium. RevenueCat receives your Maccu account identifier, your purchase and subscription history from the store, and basic technical information about the device and app. It does not receive your drawings or family profiles.

Payment details are handled by Apple or Google, never by Maccu.

How we use it

We use this information only to run Maccu: to sign you in, keep family profiles in sync, provide Premium to the account that bought it, run backups you turn on, answer your messages, and keep the service secure.

Where the law asks for a legal basis, we rely on providing the service you asked for (your account, profiles, Premium, and backups), on legal obligations (such as keeping purchase records), and on our legitimate interest in keeping Maccu secure and working.

Where drawings go

By default, artwork stays on the device. It leaves the device only when you choose one of these:

• Share or export: you pick a format and a destination in the system share sheet (a message, Photos, Files, and so on). Maccu does not follow the file after you share it.
• Premium backup: optional copies in your own iCloud (iOS) or Google Drive app data (Android). These belong to your Apple ID or Google account, and we cannot see them. You choose whether original photos are included.

If Premium ends, drawings and profiles already on the device remain.

Who helps us run Maccu

We share only what each service needs to do its job:

• Supabase: sign-in, your account, family profile records, and private profile photos.
• Brevo: delivers sign-in emails, so it receives your email address and the email itself.
• Apple or Google: the sign-in you choose, store purchases, and, if you turn backup on, files in your iCloud or Google Drive app data.
• RevenueCat: whether your account has Maccu Premium.

When the app connects to these services they also receive standard technical details such as your IP address and device type. Each of them may use your information only to provide its service and must protect it at least as well as this policy does. Some of them process data outside your country; where the law requires it, those transfers are covered by safeguards such as standard contractual clauses.

We do not use advertising networks, analytics SDKs, or crash reporting in the app. We disclose information only if the law requires it or to protect someone from serious harm, and then only as much as that requires.

Children's information

Maccu is not directed at children as account holders. A grown-up creates the account and any child profiles. Information about a child (a name, optional age, avatar, and artwork) is added by that grown-up so the sketchbook can be organised.

We do not knowingly let a child create an account. If you believe a child has done so, write to us and we will delete it. We never use children's drawings or profiles to train models or for advertising.

Your choices and rights

• Edit or remove a child profile you added.
• Delete a drawing from a sketchbook.
• Share a page only when you choose to.
• Turn Premium backup on or off, and choose whether originals are included.
• Allow or withdraw camera and photo access at any time in your device's settings.
• Delete your account in the app (see below).

Depending on where you live, you may also have the right to access, correct, export, or delete your information, to object to or restrict how we use it, and to complain to your local data protection authority. Write to hello@maccu.app and we will respond within the time the law allows.

Deleting your account

In the app, open your child's profile, scroll to the bottom, and tap Delete account. This permanently deletes:

• your Maccu account
• child profiles and profile photos
• drawings saved on that device
• Maccu backups in your iCloud or Google Drive, when the app can reach them

If you no longer have the app, you can ask us to delete the account from the Delete account page. We cannot reach drawings on your devices or files in your iCloud or Google Drive from there, so please remove those yourself.

Deleting your account does not cancel an App Store or Google Play subscription; turn that off in your store settings. Apple, Google, and RevenueCat may keep records of past purchases as billing and tax rules require.

How long we keep it

Account and profile records are kept for as long as the account exists and are deleted when you delete the account. Drawings on the device are kept until you delete them, delete the account, or remove the app. Records we must keep by law, such as purchase records, are kept only as long as that obligation lasts.

Keeping it safe

We use signed-in accounts, secure session storage on the device, encrypted connections, and private storage for profile photos. No method is perfect. Please keep your Apple ID, Google account, and email safe, especially if a child uses the same phone.

Changes

If we change how Maccu handles information, we will update this page and the date above. If a change is significant, we will also tell you in the app or by email before it takes effect.
