Privacy Policy

Last updated: September 25, 2026

This policy explains what information the Colorize app handles and why.

No account, no personal profile

Colorize does not ask for your name, email or any sign-in. The app creates a random anonymous identifier on your device. It is used to link your subscription and credits to your device and to process your requests.

Photos

You choose which photos to process. When you start a restoration or enhancement, the selected photo is uploaded over an encrypted (HTTPS) connection to our server, processed, and the result is sent back to the app. A photo is used only to create the result you asked for.

How a photo is processed

Data sent. The photo you selected and anything visible in it — people, faces, objects and text — together with your anonymous identifier, which is needed to check and charge your credits.
AI processing. To produce the result, our server sends the photo to OpenAI, a third-party AI service that processes it on our behalf through its API. OpenAI receives only the photo and the processing instructions — not your identifier or any other information about you. The result is returned directly in the response, so it is not published at a public link.
Purpose. Photos are processed solely to generate the restored, colorized or enhanced image you requested. They are not used to train our own AI models, and we do not sell photos or share them with advertisers or data brokers.

Before the first photo is sent, the app shows an AI Processing Consent screen that explains what is sent (only the photo you selected), who it is sent to (our server and OpenAI) and why. Nothing is uploaded unless you tap “Accept & Continue”. If you tap “Decline”, the photo stays on your device and is not processed. Your choice is saved on your device; after you reinstall the app you will be asked again.

Protection by third parties

We share photos only with service providers that are bound to protect them at least as well as described in this policy. OpenAI processes photos under its API terms and data processing commitments: it uses them only to provide the service to us, does not use them for training, protects them with industry-standard security, and deletes them within the period described above.

How photos are stored

On your device. Your originals, results and restoration history are saved inside the app on your device. You can delete any item in the app at any time; deleting the app removes them.
On our servers. Photos are processed in memory only and are not kept after the result is returned. Our server does not keep a photo library or gallery, and photos are never made public.
OpenAI. Under its API data policy, OpenAI does not use API data to train its models and may keep request data for up to 30 days solely to detect and prevent abuse, after which it is deleted.

Face Data

This section explains how Colorize handles faces that appear in the photos you choose to restore or enhance.

What face data we collect

Colorize does not scan your photo library and does not use the camera to capture faces. The only face data the app handles is the image of a face that appears in a photo you select yourself for restoration or enhancement. That photo is uploaded to our server as an ordinary image.

Colorize does not collect, derive or store biometric identifiers or biometric information: no facial recognition data, face geometry, facial landmarks, face templates or face prints. It does not use Face ID, the TrueDepth camera or ARKit face tracking, and it does not run face detection on your device.

How face data is used

A photo that contains faces is used for one purpose only: to generate the restored, colorized or enhanced image you requested and return it to you. The AI processing is instructed to keep each person’s appearance and identity unchanged.

Face data is not used:

to identify, recognize or authenticate any person;
to build profiles of, track or link people across photos, apps or websites;
for advertising, marketing or analytics;
to train or improve our own or anyone else’s AI models;
for any purpose other than producing the result you asked for.

OpenAI. The photo is shared with OpenAI, the AI service that performs the restoration on our behalf. It receives the photo and the processing instructions only — not your identifier or any other information about you — and processes it solely to return the result.
No selling or advertising. We do not sell, rent or disclose photos or face data to advertisers, data brokers or analytics providers.
Our servers. Photos are processed in memory only while your request is handled. They are not written to a database or a file store and are not kept after the result is returned.
Your device. The original photo and the result are stored inside the app on your device, in your restoration history.

Retention of face data

Our servers: not retained. The photo is discarded as soon as the result has been returned to the app.
OpenAI: may keep request data for up to 30 days, solely to detect and prevent abuse, after which it is deleted. It is not used to train its models or for any other purpose.
Your device: kept until you delete it. You can delete any photo from your history in the app at any time, and deleting the app removes all of them.

Support messages

If you write to us through the Support screen in the app or the contact form, we receive your message. Messages from the app also include your anonymous identifier, the app version and the iOS version, so we can look into your problem. We use them only to answer and to improve the app.

Purchases

Payments are processed by Apple. We do not receive your payment details. Subscription status and credit balances are managed with RevenueCat, which receives your anonymous identifier and purchase information.

No tracking or advertising

Colorize does not track you across apps or websites, does not show ads, and does not sell or share your data for advertising.

Permissions

The app asks for permission to add photos to your library only when you choose to save a result, and for camera access only when you scan a paper print. Photos you pick are accessed through the system picker, without access to your whole library.

Children

Colorize is not directed to children under 13 and does not knowingly collect their personal information.

Deleting your data

You can delete your photos and history in the app at any time. To ask us about any other data related to you, write to us through the contact form or the Support screen in the app.

Changes

We may update this policy from time to time. The date above shows when it last changed.
