This website keeps almost nothing.

This notice covers walltunnel.com. How the Walltunnel service handles a firm's traffic is described on the home page and in each firm's agreement.

What this site does not do

• It sets no cookies.
• It runs no analytics, advertising or tracking scripts.
• It loads nothing from other companies. Every file, including the typeface, comes from walltunnel.com.
• It has no accounts and sends nothing you type anywhere. The self-check works out its result inside your browser.
• It remembers one thing on your device if you choose it: whether you picked the light or dark appearance. That stays in your browser and is never sent.

What is recorded when you visit

The site is served by Cloudflare. Like any web server, it sees your IP address, browser, the page you asked for and the time. Cloudflare uses this to deliver and protect the site. We keep request logs for a few days to fix problems, then they are deleted. We don't combine them with anything else or use them to identify you.

If you email us

We use your message and address to reply, and to set up Walltunnel if you ask us to. We don't add you to a mailing list or share your address.
