Policy

Kien is designed as a local-first PDF reading and annotation app.

Imported PDF files stay on the user’s device by default. Kien does not upload the user’s PDF files to a server by default.

Notes, annotations, reading preferences, and local reading state are stored on the user’s device unless the user explicitly enables an optional feature that requires external processing.

Optional AI, cloud, text-to-speech, or bring-your-own-key features are controlled by the user. These features are only used when the user chooses to enable or configure them.

If the user enters their own API key for an optional provider, the key remains under the user’s control and is used only for the selected optional feature.

Kien does not sell user data.

Kien does not include social networking, public user profiles, messaging, advertising, gambling, or unrestricted web browsing.
