# Why Chess App

Chess App is a free and powerful PGN analyzer. Upload a game and get
move-by-move engine evaluation with no login and no account required.

## Why use it

- Chess engine analysis with configurable depth
- Blunder, mistake, and inaccuracy detection on every move
- Best-move arrows shown right on the board
- Free to use, no account required
- We do not harvest your data, ever

## On privacy

A lot of people are fine with getting a free service knowing the company
offering the free service spies on them, harvests data about their life and
sells it to advertisers and marketers.

I'm not fine with that. When I build an app, I build it thinking about data
security and privacy at the beginning, in the middle and at the end of the
project build.

Chess games you submit to be reviewed and analyzed stay on your device.
Playing chess, your data is saved in a central database, but it is just
whatever username you use and the chess moves.
