Privacy

Last updated September 28, 2026

This is a personal family website. We keep things simple and collect as little as possible.

What we collect

Very little. This site has no ads and no analytics or tracking scripts. Public pages don't use cookies. Some private family areas need a sign-in (see below).

Hosting

This site is hosted on Cloudflare. Like any web host, Cloudflare may process basic technical information, such as your IP address and browser type, to deliver pages and protect against abuse. See Cloudflare's privacy policy for details.

Signing in

Some areas of this site are private and limited to family members. They're protected by Cloudflare Access, and sign-in is handled at login.gruenbergs.net through Auth0.

When you sign in, these services process your name, email address, and sign-in details such as the time and IP address. They do this to confirm who you are and whether you have access. A cookie keeps you signed in for your session. We use this information only to control access to private areas, and we never sell or share it.

See Cloudflare's privacy policy and Auth0's privacy policy for details.

Contact form

If you use our contact form, we receive your name, email address, and message by email. We use them only to reply to you. The form is protected by Cloudflare Turnstile, which checks that you're a person without tracking cookies. See Turnstile's privacy notice.
