Privacy Policy

What we collect

Account details: name, email, and optionally your Telegram or WhatsApp handle and what you told us when you signed up.

Trading data you choose to connect: trade history exports you upload, and data read through a read-only exchange key (closed trades, positions, balances needed for the analysis).

Usage: which features you used and when, so that usage-based fees can be calculated.

We do not use advertising trackers. The site sets one cookie, which keeps you logged in.

How we use it

To run the service: analyse your trading, watch your rules, send the alerts you switched on, and bill usage. To answer you when you contact us. Never to sell or rent to anyone.

Keys and security

Exchange keys are encrypted the moment our website receives them, and can only be decrypted on our separate, secured analysis machine - the website itself cannot read them. Only read-only keys are accepted. Passwords are stored as one-way hashes: nobody, including us, can read them.

Uploaded files are deleted after they have been imported; only the resulting trade records are kept.

Who processes data for us

Hosting and database: Vercel and Neon (EU region). Messages: Telegram, when you link it. Payments: Stripe, if you pay by card. Market and X data come from public sources; we don't send your personal data to them.

How long we keep it

As long as your account is open. After you close it we delete your trading data within 30 days, and keep billing records only as long as accounting law requires.

Your rights

You can ask for a copy of your data, a correction, or deletion, and you can object to or limit how we use it. Email info@thechain.tech; we answer within 30 days.
