Draft dated November 11, 2026

This page says, in plain words, what this site stores about you and what happens to it. The short version: if you sign up, your email address and the time you signed up. If you do not sign up, nothing.

What is stored

Only if you type your address into the signup form and send it:

That is the whole entry. No name, no IP address, no browser or device details and no location are saved with it. Signing up twice with the same address keeps one entry.

The guessing game

If you enter a guess on the guess page, the number is added to a list of numbers. Nothing that says who you are is saved with it. The page also remembers your guess in your own browser, on your device, so it can show it to you again.

If you add an email address to your guess, that address joins the signup list described above with the label “guess”, and your guess is saved next to it so the result can be sent to you. There is no prize and nothing to buy.

Where it is stored

In Cloudflare Workers KV, a storage service run by Cloudflare, the same company that hosts this site. Cloudflare runs servers in many countries, so the entry may be kept outside the country you live in. The list is not kept anywhere else.

To stop the form from being flooded, the site also keeps a count of how many signups arrived in the current minute. It is a number only, with nothing about who signed up, and it is erased by itself about two minutes later.

Why it is stored

To send you the free weekly letter and updates about the experiment. That is the only use. Your email address is not sold and not shared for anyone else's marketing. No letter has been sent yet.

No tracking

This site has no analytics, no advertising trackers, no tracking pixels and no cookies. The signup form sends your address to this site's own server and to no one else.

Who else is involved

How to unsubscribe

Every letter will have an unsubscribe link at the bottom. Until the first letter goes out, or at any time after, you can also write to hello@heybopu.com and ask to be taken off the list.

How to ask for deletion

Write to hello@heybopu.com from the address you signed up with and ask for your data to be deleted. Your entry is then removed from the list and you get a reply to confirm it. You can also ask what is stored about you, or ask for it to be corrected.

Changes

If this page changes, the date at the top changes with it.
