Privacy Policy

Last updated: September 30, 2026

Chessmasters turns your finished chess games into coaching reports. This page explains, in plain English, what we store and why.

Accounts

We only store the email address you use to sign in and the chess games you choose to analyze.

Data

• Your coaching reports and engine notes are stored securely so you can access them later.
• We do not sell your data, run ads, or share your email with anyone.

Payments

Payments are processed by Razorpay. We never see or store your card details; Razorpay handles your payment information under its own privacy policy.

Lichess & Chess.com integration

We use the public Lichess and Chess.com APIs to fetch the game data you ask us to analyze. By using this tool, you also agree to the Lichess Terms of Service. Puzzle links redirect directly to Lichess.org.

Authentication & storage

Sign-in and data storage are provided by Supabase, which stores your data securely on our behalf.

Deleting your data

You can ask us to delete your account and analyses at any time by emailing yatharthanand2410@gmail.com.

Changes

If this policy changes, we will update this page.
