ElectroHub

Privacy Policy

Last updated: 30 July 2026

1. The short version

ElectroHub collects as little as possible: an optional account (name, email), your study progress, and anonymous page-view counts. No ads, no cookies for analytics, no selling of data, no tracking across other sites.

2. What we collect

  • Account details — if you sign in: your name, email address and (for Google sign-in) profile photo, handled by Google Firebase Authentication.
  • Study progress— saved parts, pages read, quiz history, weak spots and mock-test results. This lives in your browser's local storage; when you are signed in it is also stored in our database (Google Cloud Firestore) linked to your account so it can follow you across devices.
  • Technical logs — our hosting provider (Vercel) keeps standard server logs (IP address, request time) for security and reliability.
  • Anonymous usage stats — we count page views and page-load speed through Vercel Analytics and Speed Insights so we know which pages are worth improving. These use no cookies, set no identifier that follows you, and are not tied to your account.

3. What we don't do

  • No advertising and no ad trackers.
  • No analytics cookies and no profiling of individual users.
  • No selling or renting your data to anyone.
  • No reading of your data beyond operating the service.

4. Where your data lives

Authentication and the progress database are provided by Google Firebase; hosting by Vercel. Both process data on our behalf under their own security and privacy commitments.

5. Your choices

  • Use ElectroHub without an account — progress then stays only on your device.
  • Delete your account from the profile page; this removes your account and its synced progress from our database.
  • Clear your browser's site data to remove locally stored progress.
  • Email vijetbhat66@gmail.com for any data request we can help with.

6. Children

ElectroHub is intended for diploma and engineering students. We don't knowingly collect personal data from children under 13; if you believe a child has created an account, contact us and we'll remove it.
