Summary
ColorInvo stores your Taiwan mobile invoice carrier, barcode colors, and widget settings locally on your device. The app does not sell personal data, use third-party advertising, or require a ColorInvo account.
Stored information
- Carrier and color settings are stored in the iOS app group so the app and widget can read the same saved setup.
- Wallpaper colors are generated on device from the image you select. ColorInvo saves the selected colors and a small local preview for the Home Screen preview.
- If you email support, your email address and message content are used to respond to that request.
Photos
ColorInvo only reads the image you choose through the Apple photo picker. The app does not browse your full photo library and does not upload selected images to a ColorInvo service. The preview image stays on your device.
Sharing
The widget reads saved settings from the shared app group on the same device. ColorInvo does not share those settings with an external ColorInvo server.
Apple may process App Store downloads, purchases, diagnostics, crash reports, or TestFlight feedback under Apple policies and your settings.
Retention and control
Local settings stay on the device until you change them, remove them in the app, or uninstall ColorInvo. Support emails are retained as needed to respond to and track the request.
Website
This website is hosted at colorinvo.hsichen.dev. Hosting providers may process basic request information such as IP address, user agent, and timestamps to operate and secure the site.
