The quiz and comparison

Your quiz answers stay in your browser. They are not sent anywhere. The page loads the comparison data file from this site and nothing else.

If you unlock the checklists

Your browser's local storage keeps a flag saying this device is unlocked, plus the address of your checklist page. Both stay on your device. Clearing site data removes them.

Payment happens on Stripe's own pages. This site does not receive or store your card details.

If you use the contact form

The site stores what you send: your name (if given), your reply address, the topic, your message, the time, and a salted one-way hash of your IP address. The hash is used only to limit how many messages one connection can send per hour. Messages are stored in a Cloudflare D1 database that the site owner reads. To ask for your messages to be deleted, use the contact form.

What this site does not do

No analytics, no trackers, no advertising cookies and no third-party scripts. The site is hosted on Cloudflare Pages, and Cloudflare processes requests in order to serve it.
