Is chess helper safe?
chess helper sends Lichess game IDs and entered FEN chess positions to a Google Cloud Run API for chess analysis.
When you request a suggested move from a Lichess tab, the extension extracts the game ID from the tab URL and sends it to its Cloud Run API. If you enter a FEN position for evaluation, that position is also sent to the same API and the returned chess analysis is shown in the extension UI.

Where it sends data
Destinations our analysis observed chess helper contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
