NumberArtPrivacy Policy
Turn your photos into paint-by-numbers projects to print and paint on paper.
Who operates NumberArt
NumberArt is developed by Guilherme Molon. Contact: contact@guilhermemolon.com. This policy describes the app and these NumberArt support pages.
Photos and processing
You choose a photo through the iOS photo picker. Conversion takes place on your iPhone. The app does not upload your photo or drawing to a server and does not change the original photo. It keeps the current image and preview in memory, without a saved project library or image history.
Data collection
The app has no accounts, advertising, analytics SDKs or tracking. It does not collect or transmit personal information or usage analytics to the developer.
Temporary files and sharing
The app creates a temporary PDF to share. It removes its temporary export when the share sheet closes; if the app is interrupted, a temporary file may remain until iOS removes it. Files you save or share remain in the location you choose. Other apps or services receive the exported PDF only when you choose them and handle it under their own policies.
Purchases
Apple handles App Store purchases under its own terms and privacy policy. NumberArt does not receive your payment card information.
Support emails and website
If you email support, we receive the address and content you voluntarily send and use them to respond to your request, not for advertising. These support pages contain no analytics scripts or advertising cookies. The hosting provider, GitHub Pages, may process ordinary technical access logs under its own privacy statement. Opening these pages is optional and does not send the selected photo.
Your choices
You can remove the app to remove its local app data, and delete exported files from where you saved them. To request deletion of support correspondence, contact us at the email above. There is no server-side photo history or account to delete.
Updates
We may update this policy when the app or support practices change. Updated: 2026-11-03.
