# Open in Lichess Privacy Policy

Last updated: 2026-07-27

Open in Lichess converts a chessboard image selected by the user into a chess
position and opens that position in the Lichess board editor.

## Data handled

When the user explicitly chooses **Open board in Lichess** from an image's
context menu on Facebook, the extension temporarily handles:

- the selected image;
- the selected image's source URL; and
- the chess position recognized from that image.

The image and recognition result are processed locally on the user's device.
They are not uploaded to the developer or to a third-party recognition
service. The image URL is kept only in Chrome's in-memory session storage long
enough to transfer the user-initiated request between extension pages, then it
is removed.

The recognized chess position is included in the Lichess editor URL when the
extension opens `https://lichess.org`. Lichess's own privacy policy applies to
the user's interaction with that site.

## Data collection and sharing

Open in Lichess does not:

- create user accounts;
- collect analytics or telemetry;
- retain browsing history;
- sell user data;
- use data for advertising or credit decisions; or
- transfer user data for purposes unrelated to its single function.

## Permissions

The extension uses:

- **Context menus** to provide the user-invoked image action.
- **Session storage** to pass the selected image URL between extension
  components and remove it immediately after retrieval.
- **Website access** limited to Facebook and Facebook's image CDN, used only to
  fetch the image that the user explicitly selected. The extension does not
  continuously inspect pages or browse in the background.

## Changes

Material changes to this policy will be reflected here with an updated date.
