LeetStack Browser Extension
Last updated: 11/30/2025
We built the LeetStack Chrome extension to help you capture practice notes without collecting any unnecessary information. This page explains exactly what data we handle and how it is used.
Information We Collect
- Email address: used to send you a one-time login link or OTP through Supabase authentication.
- Problem content you explicitly save: when you click “Save,” we capture the code, notes, or metadata you provide and store it securely on the LeetStack backend.
We do not record or transmit any other browsing data, page content, or personal information unless you intentionally submit it through the save action.
How We Use Your Data
The data you provide is used only to create and sync your LeetStack notes so you can review them later in the LeetStack mobile app or web dashboard. We do not sell or share your data with advertisers or unrelated third parties. Supabase is our authentication provider and receives your email solely to deliver the OTP email.
Storage & Security
Saved content and account information are stored in our managed cloud databases (AWS + Supabase). Access is limited to authenticated requests from the extension or our backend services, and all communication occurs over HTTPS.
Your Choices
You can delete saved notes at any time from the LeetStack interface. If you would like your account or data removed entirely, contact us and we will process the deletion promptly.
