Privacy Policy

Last updated: 9 May 2026

This page explains what data we collect, why, and how to remove it. Plain language, no dark patterns.

What we collect

• Email address — when you create an account.
• Quiz answers — your responses to the Domain Finder and Roadmap quizzes, so we can generate your personalized roadmap.
• Progress data — which subtopics you mark as complete in a paid roadmap.
• Payment metadata — Razorpay payment IDs and purchase records (we do not store card numbers, CVV, UPI IDs, or net-banking credentials; Razorpay handles those).
• Basic technical logs — server logs from Vercel (timestamps, paths, status codes). Used for debugging and abuse prevention. Not used for advertising.

What we do not collect

• No analytics or marketing trackers
• No advertising cookies
• No payment card data
• No precise location data

Why we collect it

Strictly to run the service: log you in, save your progress, generate your AI roadmap, and process your payment. Nothing else.

Third parties we use

• Supabase — authentication and database. Stores your email, hashed password, quiz answers, progress, and entitlements.
• Razorpay — payment processing. Razorpay handles your card or UPI details directly.
• Vercel — hosting. Receives server logs.
• Google Gemini API— generates the AI portions of your roadmap. Your quiz answers are sent to Gemini for that generation. Google's privacy policy applies.
• Groq — generates short mid-quiz reactions. Your in-flight quiz answers are sent to Groq for that purpose.

Cookies

We use one cookie: a session cookie set by Supabase to keep you logged in. It is HTTP-only, SameSite=Lax, and expires when the session ends. We do not use third-party tracking cookies.

Data retention

We keep your account data as long as your account is active. Purchase records are kept for 7 years for tax and accounting purposes, as required by Indian law.

Your rights

Email labsofece@gmail.com to:

• Request a copy of your data
• Correct your data
• Delete your account and all associated data (purchase records may be retained for tax compliance)
• Withdraw any consent you have given

Children

ECE Lab is intended for college-age students. We do not knowingly collect data from children under 13. If you believe a child has signed up, email us and we will delete the account.

Changes

We will update the "Last updated" date if this policy changes. Material changes will be highlighted on the homepage.
