What BacktestAI keeps about you, why, and who else sees it. In plain words.

Last updated 3 November 2026

What we keep

  • Your account: your name and email. Your password is stored only as a one-way hash, never as text. If you sign in with Google, we receive your name and email from Google.
  • Your sign-ins: the browser and the IP address of each session, to keep your account safe.
  • What you make: your conversations with the Quant AI agent, your strategies and their versions, their code, their tests and trades, your Backtest Studio sessions with the chart images of your trades, and your trading journal.
  • What you share in the Community: your posts, comments, stars and direct messages.

Voice notes are turned into text and then discarded; we do not store the recording. Images you attach to a message are kept with that conversation.

Why we keep it

Only to run BacktestAI for you: to sign you in, to let the agent remember your work, to test your strategies, and to show your Community posts to other traders. We do not sell your data, and we do not show advertising.

Who else sees it

  • Meta: the agent runs on Meta's Muse models through the Meta Model API. What you send the agent (your messages, code, chart images and voice notes) goes to Meta to produce its answer.
  • Google: only if you choose to sign in with Google.
  • Our email provider: your address, when we send you a password reset link.
  • Other traders: what you publish in the Community, and the messages you send them. The code of a Pro EA stays on our servers and is never shown to anyone.

Cookies and browser storage

We use one cookie, which keeps you signed in, and your browser's local storage for your preferences and open work. There are no advertising or tracking cookies, and no analytics.

Your control

You can delete your strategies, tests and Backtest Studio sessions in the app at any time. To receive a copy of your data, or to have your account and everything in it removed, contact the BacktestAI team.

If this changes, we update this page and its date. For how you may use BacktestAI, read the terms.
