Privacy Policy

Last updated: July 4, 2026

What we collect

When you create an account, LearnStack stores your email address and the display name you choose. That is the only account data we collect.

Authentication

Sign-in is handled by Supabase Auth. Your password is stored as a salted hash by Supabase; LearnStack never sees or stores your plaintext password.

What we store about your activity

Your reading of articles requires no tracking. If you use the learning modules, we store your per-section completion state and any personal notes you write, linked to your account so they sync across your devices. Notes are visible only to you.

Cookies

We use cookies solely to keep you signed in (session cookies set by Supabase Auth). There are no analytics cookies, no advertising cookies, and no third-party trackers.

What we don't do

• No analytics or usage tracking.
• No advertising.
• No sale or sharing of your data with third parties.
• No payment data — the service is currently free. Paid tiers may be introduced later; if that happens, this policy will be updated before any payment data is collected.

Where your data lives

LearnStack is hosted on Vercel, and data is stored with Supabase, both in United States regions.

Account deletion

You may request deletion of your account and all associated data at any time by emailing bhaskar.knp@gmail.com.
