Privacy policy

Effective October 4, 2026

Letterloom is provided by Zhe Wu under the MindCoreAI brand. Your photos and words are processed on your device. The developer does not operate a photo-processing server or app account system for Letterloom. The app includes no advertising or analytics SDKs, and the developer does not collect your photos, messages, advertising identifiers, or usage analytics from the app.

Images, words, and permissions

When you select a photo or a file, the app receives the image you choose and uses it to render your artwork locally. The system pickers do not grant Letterloom unrestricted access to your photo library or all of your files. Any characters or personal messages you enter are used locally to create the portrait.

Letterloom requests add-only Photos permission when you choose Save to Photos. You can change that permission in Settings. Revoking permission does not remove images you have already exported.

Local storage and retention

The selected image, words, editing layout, and undo state are held in memory during use. Letterloom does not provide saved editable projects. Exported files created for sharing are written to the app's temporary directory. Successful exports are not automatically deleted when sharing finishes; they remain until iOS clears temporary storage or the app is removed. The developer cannot remotely retrieve or delete these files.

Images and files you save to Photos, Files, or other destinations remain there until you delete them from those destinations. Removing Letterloom does not delete exports you saved elsewhere. Device backups and iCloud synchronization depend on your Apple and destination-app settings.

Purchases and Apple services

Apple's App Store handles Print Studio purchases and restores. Letterloom checks verified StoreKit transactions on your device to determine whether the unlock is available. The developer does not receive your payment card details or send your purchase history to a developer-operated server.

Apple independently processes Apple Account, billing, transaction, and device-service information under the Apple Privacy Policy.

Sharing you choose

If you share an export, the destination app, service, or recipient receives the file you choose to share. That destination may process or store it under its own privacy policy. Letterloom does not automatically upload your artwork to a developer service.

Support and this website

If you email support, the developer receives the email address and information you voluntarily send and uses them to answer your request. Please avoid sending private photos or credentials unnecessarily. Email is processed by the email provider; contact eu8929@gmail.com to ask about information you supplied in a support request.

This website is hosted on GitHub Pages. It contains no advertising or analytics scripts. GitHub may process web request information for hosting and security under the GitHub Privacy Statement.

Updates and questions

If Letterloom's data practices change, this policy and the App Store privacy disclosure will be updated. Send privacy questions to eu8929@gmail.com.
