Privacy Policy

Last updated: November 13, 2026

BackForFree ("we", "us") runs backforfree.com, a free simulator for practising prop-firm evaluations on historical market data. This policy explains what data is involved when you use the site.

What we store

Without an account, your challenge sessions (settings, simulated orders, trades and progress) are saved only in your browser's local storage on your device. We cannot see them, and they are deleted if you clear your browser's site data.

With an account (optional), we store: your email address and name from Google (you sign in with your Google account; we never see your Google password), a display name you choose (shown publicly on the leaderboard if you have a verified passed challenge), and your challenge sessions including the recorded simulated orders, so they sync across devices and can be verified. Leaderboard entries show only your display name and the challenge result, never your email address. Accounts are hosted by Supabase (supabase.com), which acts as our data processor and stores the data in its cloud (currently in Singapore). Deleting a challenge in the app deletes it from your account; to delete your account and all its data, email us.

Advertising

The site is funded by advertising. Our advertising partners (for example Google AdSense) may use cookies, device identifiers and similar technologies to show and measure ads, which may include personalised ads based on your visits to this and other websites. Where required by law, we will ask for your consent before such cookies are used. You can learn how Google uses data at policies.google.com/technologies/partner-sites and opt out of personalised advertising at adssettings.google.com.

Hosting and logs

The site is served by a hosting/CDN provider, which may process technical data such as your IP address, browser type and request times to deliver the site and protect it against abuse.

Third-party content

Historical futures data is provided by Massive (massive.com) under licence; crypto data comes from Binance Vision under CC BY-NC-SA 4.0; forex and CFD data comes from HistData.com. Charts are rendered in your browser with the open-source KLineChart library.

Children

The site is not directed at children under 16, and we do not knowingly collect their personal data.

Your rights

Depending on where you live (for example under the GDPR or CCPA), you may have rights to access, correct, delete or export your personal data and to object to its processing. For account data, email us from the address on your account and we will act within 30 days. For advertising data, contact us and we will help you reach our advertising partners.
