Your Data on This Site

This site is run by one person for academic purposes. Little data is collected, the purpose is clear, and none of it is sold.

Last updated: 4 September 2026

Who runs this site

irsyads.com is owned and run personally by Muhammad Irsyad Sirojul Khoeir. No company, marketing team, or third party takes part in running it.

What is collected

Only what you send yourself:

  • Contact form — your name, email address, and message.
  • Comments — your name and the comment itself. Comments are reviewed before they appear.
  • Account & sign-in — your email address. If you sign in with Google, this site receives your Google name, email address, and profile picture. It never receives your Google password.

What is never done

  • No advertising and no ad trackers.
  • No third-party analytics — no Google Analytics or similar.
  • Your data is never sold, rented, or traded.
  • No marketing email. Replies are sent only to answer your message.

How the data is used

  • To answer questions or requests you send.
  • To display comments that have been approved.
  • To recognise you when signed in, and to decide which material you may access.

Where the data is stored

Data is stored in a Supabase (PostgreSQL) database with row-level access rules, and the site is served through Cloudflare. Both are infrastructure providers — they process data on this site's behalf, not for their own purposes.

Read and write access to personal data is restricted to the site owner's account.

Cookies and browser storage

This site uses no tracking cookies. Your browser stores only a sign-in session marker (so you need not sign in repeatedly) and display preferences such as dark/light theme and language. All of it disappears when you sign out or clear your browser data.

How long it is kept

Messages and comments are kept as long as they remain a useful record of the conversation. Account data is kept while your account is active. You may request deletion at any time.

Your rights

  • Request a copy of the data held about you.
  • Request correction of inaccurate data.
  • Request deletion of your account and related data.
  • Revoke Google sign-in access at any time from your Google Account settings.

Children

This site is not intended for children under 13 and does not knowingly collect their data.
