Privacy policy: Upsharp

Last updated: 14 November 2026

This page covers Upsharp, the download from kayabyte.dev. Kayabyte’s general policy for the Mac apps is at kayabyte.dev/mac/privacy; where the two differ, this page applies to Upsharp.

Short version

Upsharp collects no data about you and uploads no images.

Your images

Images are read, processed on your Mac and written where you choose. The AI models are inside the app. Nothing is sent anywhere. Settings are stored on your Mac in the app’s container (~/Library/Containers/dev.kayabyte.mac.upsharp).

Network

The download contacts kayabyte.dev only to activate or check a licence (the licence key and an anonymous device code; no images, no file names) and to look for updates. There is no account, no analytics, no crash reporting, no advertising and no tracking. The Mac App Store edition, which is coming, is built without network access.

Purchases

Paddle is the merchant of record and handles payment details and tax; we receive your email address and order to issue the key. Paddle’s privacy policy applies.

Support email

If you write to support@kayabyte.dev, we use your email only to answer you and delete the conversation when it is no longer needed.
