What we collect, and what we don't

The device collects nothing

SolveBlock has no Wi-Fi, no Bluetooth and no radio of any kind. Your solves, sessions and statistics are stored on the device and go nowhere. There is no account, no login, no telemetry and no sync. Nothing to opt out of, because there is nothing to opt into.

This website

These pages are static. We do not run analytics, advertising or tracking scripts, and we do not set cookies.

The feedback form

If you fill in the waitlist form, the answers you give — including your name and email address — are delivered to us by email through Formspree, a third-party form service, and are subject to their handling in transit.

We use what you send for three things:

• Adding you to the waitlist
• Selecting who receives one of the first production units, and contacting them
• Deciding what to build, and what to charge, for SolveBlock

We do not sell it, share it with anyone outside the two of us, or add you to anything you did not ask for. If you would like your entry deleted, email us and we will remove it.

The waitlist

Sending the form puts you on the waitlist — that is what the form is for, and the page and the button both say so before you send it.

We will email you about three things, and nothing else:

• When SolveBlock is ready to buy
• When there is a price
• If you are selected to receive one of the first production units

That is the whole list. It is not a newsletter, it will not be frequent, and we will not send you anything else or let anybody else send you anything. Reply to any of it and we will take you off, no questions asked; you can also email us at any time to be removed.
