Privacy policy

Chart Lab can be used worldwide without a verified identity account. We store only what is needed for the app to work. We do not store money or identity documents.

1. Stored on your device

The browser stores the login session in an HttpOnly cookie and may store a display name in localStorage. We do not use advertising cookies.

2. Stored on the server

Username, email, hashed password, and display name
Session token until it expires or you sign out
Chart-analysis logs: typed context, file type, file size, and the analysis text — we do not intend to keep the image file permanently
Email is used to verify the account, reset a forgotten password, and send security notices — not for ads

There is no KYC, no address, no national ID, and we do not take broker API keys.

3. Uploaded chart images

When you tap Analyze chart, the image is sent to Anthropic’s Claude vision model to summarize what is in the picture. Do not upload images that contain personal data you do not want processed.

4. Third-party market data

Rankings, prices, logos, and charts come from public services such as CoinGecko, CoinMarketCap, Binance, and TradingView. Those calls are market data, not your bank-account data.

5. We do not sell data

We do not sell user lists and we do not use in-app data to target third-party ads.

6. Users in every country

This policy applies to users everywhere as educational software. If your local law limits market-watch tools, you decide whether to use the app.
