Lade is a Chrome extension and companion web dashboard that runs live, voice-based mock interviews on LeetCode problems. This page explains what data the extension and dashboard collect, how it's used, and what is never stored.
Signing in uses Google OAuth via Supabase. We receive and store your email address, display name, and avatar URL as provided by Google. This is used solely to identify your account and associate it with your session history and plan.
During an interview session, the extension captures microphone audio and streams it to our backend in real time so the AI interviewer can respond to what you say. Audio is never written to disk or stored — it exists only transiently in memory while a session is active, and is discarded once the session ends.
We store a record of each interview session you complete, so you can review it later in your dashboard:
We do not store transcripts, recordings, or your submitted code.
The extension only runs on leetcode.com/problems/* pages, where it reads the problem title, difficulty, and description to brief the AI interviewer, and observes your code editor to give feedback as you work.
If you upgrade to a paid plan, checkout is handled entirely by Stripe. We do not store your card details — Stripe shares back only your subscription status, which we use to determine your plan.
We do not sell your data. Data is shared only with the service providers required to run Lade: Supabase (authentication and database), our AI providers (to generate interview responses), and Stripe (billing, if applicable).
You can delete your account and all associated data at any time by contacting us below.
