Cookie notice.

What this website stores in your browser

• Theme preference (dark or light) in local storage, set only when you use the theme switch. It never leaves your browser.
• Campaign tag in session storage, set only when you arrive through one of our ads or tagged links (the utm_ parameters in the address). It is erased when you close the tab and leaves your browser only if you join the launch list.

What it does not do

• No analytics, no advertising pixels, no social media embeds, no third-party fonts loaded from external servers.
• No cookies are set by the website itself.

The launch list

If you submit the launch-list form, the e-mail address and platform you entered, and the campaign tag if you arrived through a tagged link, are saved to a private Google Sheet that we use to send one launch announcement. This is a form submission, not a cookie, and it happens only when you press the button.

The app
