Privacy Policy
Last updated: 16 July 2026
Linometry ("the app") is made by LA BRANDS LTD ("we", "us"), a company registered in the United Kingdom. We are the data controller for the personal data described in this policy. We take a simple view of privacy: we collect the minimum needed to run a colouring app well, we never sell your data, and we show no advertising.

1. What we collect and why
| Data | Why we collect it | Legal basis (UK GDPR) |
|---|---|---|
| Email address, display name, password (stored as a salted hash — we can never read it) | Creating and securing your account; syncing artwork across your devices | Contract (Art. 6(1)(b)) |
| Sign-in identifiers from Google or Apple (a token identifying your account; we receive your email and, with Apple, an optional name) | Letting you sign in without a password | Contract |
| Your artwork, projects, palettes, gallery posts, comments and likes | The core service: saving, syncing and (only when you choose to publish) sharing your work | Contract |
| Purchase and subscription status (processed by Google Play / Apple and RevenueCat — we never see your card details) | Unlocking Premium on your account and honouring purchases across devices | Contract |
| Basic usage events (e.g. app opened, page opened) tied to your account id | Understanding which content is used so we can improve the library | Legitimate interests (Art. 6(1)(f)) |
| Crash reports (device model, OS version, app version, stack trace; processed by Sentry) | Finding and fixing bugs and crashes | Legitimate interests |
| Photos you choose to import | Creating colouring pages, spiral portraits or palettes from your photos — only photos you explicitly pick | Contract |
We do not collect your precise location, contacts, or advertising identifiers. We do not profile you, and we do not sell or rent personal data to anyone.
2. Photos you import
When you use the creator tools, the photo you pick is uploaded to our server, converted into a colouring page or palette, and the result is stored with your account. The generated page is private to your account unless you publish artwork made from it. You can delete any created page or project at any time, which removes the associated images from our storage.
3. Payments
Purchases are processed by Google Play (and, on Apple devices, the App Store). We use RevenueCat to validate purchases and manage subscription status. We receive confirmation that a purchase happened, the product purchased, and its expiry date — never your payment card, bank details or billing address.
4. Who we share data with (processors)
- Railway — hosts our server and database (EU region).
- RevenueCat — purchase validation and subscription management.
- Google — Google sign-in and Google Play billing.
- Apple — Apple sign-in and App Store billing (on Apple devices).
- Sentry — crash and error reporting.
Each processor only receives what it needs to do its job, under its own data-processing terms. Some processors are based outside the UK/EEA (for example in the United States); transfers rely on adequacy decisions or standard contractual clauses.
5. How long we keep data
- Account & artwork: for as long as your account exists.
- Gallery posts: until you delete them or your account.
- Crash reports: up to 90 days.
- Server logs: up to 30 days.
Deleting your account (Settings → Delete account) permanently removes your account record, synced artwork, palettes, gallery posts, comments and likes from our systems. Artwork stored locally on your device stays on your device. Backups age out within 30 days.
6. Your rights
Under UK GDPR you can ask us to:
- access a copy of the personal data we hold about you;
- correct inaccurate data;
- delete your data ("right to be forgotten") — also available in-app;
- restrict or object to processing based on legitimate interests;
- receive your data in a portable format.
Email luke@la-brands.com and we will respond within one month. You also have the right to complain to the UK Information Commissioner's Office (ico.org.uk).
7. Children
Linometry is a general-audience colouring app. Creating an account requires agreeing to our terms; children under 13 should only use the app with a parent or guardian's consent and supervision. We do not knowingly collect personal data from children under 13 without such consent — if you believe this has happened, contact us and we will delete it.
8. Security
All traffic between the app and our servers is encrypted (HTTPS). Passwords are stored only as salted hashes. Access to production systems is limited to LA BRANDS LTD personnel who need it. No system is perfectly secure, but if we ever discover a breach affecting your personal data we will notify you and the ICO as required by law.
9. Changes to this policy
If we make material changes we will update the date above and, for significant changes, notify you in the app. Continued use after changes take effect means you accept the updated policy.
