What we keep, and who can see it

• Your account: your email address and your public handle. If you set a password, we store only a scrypt hash of it, never the password itself.
• If you sign in with Google: Google’s id for your account, your profile picture’s address, and your name, which is used only to suggest a handle and is never shown.
• API keys: a hash and the first few characters, so you can tell your keys apart. The key itself is shown to you once and not kept.
• What you save: strategies and backtests you choose to save, their results and trades, and forward tests you start. A backtest you don’t save is not stored; it is only counted towards your weekly limit.

Your handle, your profile page and your public strategies and results. Your email address is never shown to anyone.

On the free plan, strategies you save are public; saving privately needs a paid plan. You are told which each time you save. A strategy you make private or delete comes off the public pages, results included.

One cookie keeps you signed in, for up to 30 days. Signing in with Google adds two more that last ten minutes and are removed when you get back. Nothing else.

• Vercel runs the website. Like any web host it keeps short-lived request logs, which include IP addresses.
• Neon hosts the database, in the United States.
• GitHub runs the hourly job that updates forward tests.
• Cloudflare manages our domain and stores market data, which contains nothing about you.
• Google, only if you choose to sign in with it.

Market prices come from Binance’s public archive. Binance learns nothing about you from it.

You can change your handle and delete strategies yourself. To delete your account and everything in it, email support@aibacktester.app from the address on the account, and it will be done within 30 days.

AI Backtester is not meant for anyone under 18.

If what we collect changes, this page changes first, with a new date at the top. Questions go to support@aibacktester.app. See also the terms.
