privacy

Privacy, plainly.

Dreamstorm is a free set of brainstorming games. Here’s everything it keeps, and why.

Without an account

Play as much as you like without signing in. Anything you save goes into your notebook, which lives only in this browser, on this device. It never reaches us.

With an account

If you sign in, we keep your email address (and your name, if you sign in with Google) so we know which notebook is yours, along with the sparks and maps you save, so they follow you to your other devices. They’re private to you. Nobody else can see them.

What we never do

No ads, no tracking, and no selling or sharing your information. We only email you to send a sign-in code, or to answer a note you sent us.

Cookies

Signing in sets one cookie that keeps you signed in, plus a tiny one that tells the page you’re signed in. That’s all: no advertising or analytics cookies. Email sign-in and the contact form also use Cloudflare Turnstile, which checks that you’re a person and not a bot.

Games that reach out

Unasked sends what you type to an AI model that Cloudflare runs, which writes the next question. We don’t keep what you typed. Relics shows pictures from public collections (the Art Institute of Chicago, the Met, the Cleveland Museum of Art, NASA, Wikimedia Commons and Openverse), so those sites see a request for an image. Names can open a domain-name search on another site when you ask it to.

Where it lives

On Cloudflare, which runs this site. Sign-in emails are sent through Resend. Messages from the contact form go to our inbox so we can reply.

Deleting it

Signed in? Open the account menu (your initial, top right) and choose delete account. It erases your account and everything saved to it, right away. You can also just ask us.
