Privacy policy

Last updated 28 October 2026.

Lowlight is a personal desktop app with one user: the person who made it and runs it on her own computer. This policy says what it does with Google user data.

What it accesses

With the user's permission, given when she signs in with Google, Lowlight reads and changes events in her own Google Calendar: their titles, times, descriptions, locations and reminders. It asks for nothing else from her Google account.

How it uses it

• To show her upcoming events inside the app.
• To let the companion in the app see her week, and add, change or answer events when she asks. Removing an event needs her yes first.
• To do that, the events the companion is looking at are sent, as part of the conversation, to the AI model she has chosen in the app (Anthropic's Claude or OpenAI's models), under her own accounts with them. Nothing else is done with them there.

Where it's kept

The Google sign-in is kept on her computer, in Windows Credential Manager. Calendar events are read when needed and kept only in the app's own storage on her computer. Lowlight has no server of its own, and no copy of the data is kept anywhere else.

Sharing

Google user data is never sold, never used for advertising, and never shared with anyone except as described above, to give her the features she asked for.

Lowlight's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Removing access

She can sign out of Google in Lowlight's Settings at any time, which deletes the stored sign-in from her computer, and she can remove Lowlight's access entirely at myaccount.google.com/permissions.

Questions

Lowlight has one user, and she is also its developer. Questions about this policy go to her, through the developer contact given on Google's sign-in screen.
