Coloring Studio · Last updated: June 19, 2026
This Privacy Policy explains what Coloring Studio ("we", "us", "our") does — and does not do — with your information when you use the Coloring Studio app (the "App"). We built the app to be privacy-first.
You can use the app without creating an account. We do not ask for your name, email address, phone number, or social media accounts to use the app.
When you create a coloring page, the photo you choose is sent to our processing service only to generate your coloring page. We do not store your photos on our servers — they are processed in memory and discarded immediately after your coloring page is created. We do not use your photos to train AI models, and we never sell them.
To convert your photo into line art, we send it to our third-party AI processing provider, Replicate, solely to generate the requested coloring page. Replicate processes the image transiently to return the result and does not retain it for this purpose. See Replicate's privacy practices at replicate.com/privacy.
To run the service, prevent abuse, and manage subscriptions, our servers store a small amount of non-personal data: an anonymous install identifier; a device-integrity token (Apple App Attest / DeviceCheck) used to prevent abuse and enforce the free tier; and your subscription status from Apple (e.g. active/expired, product, renewal or expiry dates). This data is not linked to your real-world identity and excludes your name, email, and photos.
We do not collect your location, contacts, social media data, or browsing history. We do not use third-party advertising or analytics SDKs, and we do not track you across other apps or websites.
Subscriptions and credit packs are processed by Apple. We verify your purchase status with Apple's servers and never see or store your full payment details.
Camera and photo-library access are used only to let you choose or take a photo and to save your results to your device. You can manage these permissions in iOS Settings.
The app is family-friendly and rated for all ages. We do not knowingly collect personal information from children, and no account or personal data is required to use the app. If you believe a child has provided us personal data, contact us and we will delete it.
Photos are not retained — they are processed in memory and discarded immediately. The limited non-personal data above is kept only as long as needed to provide the service and meet legal obligations.
Depending on where you live, you may have rights to access, correct, or delete your data. Because we do not hold data that identifies you personally, most requests relate to your subscription or device records. Email us and we will help.
Your data may be processed on servers located outside your country of residence. We take steps to ensure it is protected under applicable data-protection laws.
We may update this Policy; significant changes will be noted in the app. Questions? Email [email protected].
