Privacy Policy

Effective 2026-10-16. Inkpic is made by PRODUCTIVITY TOOLS LIMITED, Hong Kong. Questions: support@productivitytools.app.

Your photos are not stored

When you make a coloring page, the photo you chose is sent from your phone to our server and from there to OpenAI, the AI provider that draws the page. The photo and the page exist on our server only in memory for the seconds the request takes. We do not save them, back them up, or look at them. OpenAI processes the photo under its API data policy: it is not used to train OpenAI models and may be kept by OpenAI for up to 30 days for abuse monitoring, then deleted.

What we do keep

• App identifier. A random id created on your phone the first time you open the app. There is no account, name, or email. The id counts your pages and links your subscription.
• Generation log. For every page: the app identifier, your IP address, the detail level, how long it took, the app version, and your phone's language and region. Used to enforce the page limits, to spot abuse, and to understand how the app is used. Deleted or anonymised within 12 months.
• Reports. If you report a page, we keep the reason you gave and the log entry of that page.
• Purchases. Payment goes through Google Play or the App Store; we never see your card. RevenueCat, our subscription service, receives the app identifier and the store receipt to tell us whether your subscription is active.

The app contains no analytics or advertising SDKs. We do not sell or share data for advertising.

Where it is processed

Our server runs on Railway; the AI provider is OpenAI; subscriptions are handled by RevenueCat. Each processes data only to provide the service described here.

Children

The app is for adults. We do not knowingly collect data from anyone under 18. Photos you choose remain your responsibility; choose photos you have the right to use.

Your rights

Email us to delete the log entries tied to your app identifier (the Support screen in the app shows it) or to ask what we hold. Subscriptions are cancelled in Google Play or the App Store.

Changes

Updates are posted on this page with a new effective date.
