Privacy policy
What we collect when you use SitePreview, why, and how long we keep it.
Last updated 25 September 2026
What we collect
When you create a preview
We store the domain, the server IP address, whether the server answered over HTTPS or HTTP, when the preview was created, how long it lasts and how often it has been viewed. If you're signed in, we also store your account ID and email address with the preview so it appears in your dashboard.
When you use a preview link
Requests made through a preview link pass through our server to the website being previewed. We don't add tracking, analytics or advertising to previewed pages. Our server logs record the pages requested, for troubleshooting and to prevent abuse.
When you create an account
Accounts are handled by Google Firebase Authentication, which stores your email address and a secure hash of your password. We never see or store your password.
When you contact us
We receive your name, email address and message by email so we can reply.
How long we keep it
- Previews: until the link expires, then deleted automatically.
- Server logs: 14 days.
- Accounts: until you ask us to delete your account.
- Messages: only as long as we need to deal with your request.
Cookies
SitePreview sets a session cookie and a security (CSRF) cookie on sitepreview.org so forms and sign-in work. We don't use advertising or analytics cookies. Websites you preview may set their own cookies, which we translate to the preview address so the site works.
Services we use
- Google reCAPTCHA checks that forms are sent by people, not bots.
- Google Firebase Authentication handles accounts and sign-in.
- jsDelivr serves the code that draws QR codes. The QR code itself is made in your browser, so your preview link isn't sent to anyone.
Your rights
You can ask to see the personal data we hold about you, have it corrected or deleted, or object to how we use it. To make a request, use our contact form. If you're unhappy with how we handle your data, you can complain to the Information Commissioner's Office (ICO).
Changes
If we change this policy, we'll update this page and the date at the top.
