Privacy Policy

Last updated: 23 May 2026

This Privacy Policy describes how the Nhuga Backtesting Engine Chrome extension ("the Extension") handles your information.

1. Information we collect

• Email address — used as your login identifier.
• Authentication session tokens — short-lived tokens from our authentication provider after sign-in.
• Local strategy configurations — parameters you choose for backtesting, stored locally in your browser only.

The Extension does not collect: browsing history, contents of pages other than what is necessary for triggered backtests, financial account details, or personal information beyond your email.

2. How we use your information

• Email and password authenticate you against our login server (Supabase).
• Session tokens are stored locally in chrome.storage.local so you don't re-login each time.
• Strategy configurations stay on your device.

3. Third-party services

We use Supabase (https://supabase.com) for authentication. Email and password are sent over HTTPS to Supabase. Passwords are hashed by Supabase using industry-standard methods and never returned to the Extension. Full Supabase privacy: https://supabase.com/privacy

4. Data sharing

We do not sell, rent, or share your personal data with third parties.

5. Data retention

Your account remains in our authentication system until you request deletion or the administrator removes it. Local session data is removed when you sign out or after 30 days of inactivity.

6. Permissions

• storage, unlimitedStorage — save session tokens and strategy results locally.
• activeTab — communicate with the TradingView chart when you trigger a backtest.
• host_permissions: *.supabase.co — authenticate against our login server.

7. Your rights

Sign out of the Extension or remove it from your browser to clear local data. To delete your account, email the administrator below.

8. Contact

For privacy questions or account deletion: jaxnijan@gmail.com
