Question 1

How does the Chess Year in Review work?

Accepted Answer

Enter your Chess.com or Lichess username and pick a year. Plychess fetches your public game history directly from the official Chess.com or Lichess API in your browser and computes stats like win rate, favorite opening, and longest game — nothing is stored on our servers.

Question 2

Is this an official Chess.com or Lichess feature?

Accepted Answer

No. This is an independent tool built by Plychess using each platform's public read-only game API. It is not affiliated with, endorsed by, or run by Chess.com or Lichess.

Question 3

Do I need to log in or connect my account?

Accepted Answer

No. Only your public username is needed. Your games are fetched from the platform's public API and processed locally in your browser for that single session.

Question 4

How many games does it analyze?

Accepted Answer

Up to the first 1,500 Chess.com games or 1,000 Lichess games found for the selected year, depending on the platform's public API limits.
