Privacy

Last updated 2026-10-08. This page covers grindos.fit, the marketing site. The GrindOS app has its own terms inside the app.

What is stored when you join the waitlist

Your email address, the time you signed up, which form you used (the top of the page or the bottom), when we last sent you a confirmation link, and the time you confirmed. Nothing else.

Why

To invite you to GrindOS early access and, later, to tell you when it launches. No other marketing use without a separate opt-in.

Who processes it

Cloudflare hosts this site, stores the list in its D1 database, and runs the Turnstile bot check on the form. Turnstile receives the usual request metadata, such as your IP address and browser details, to decide whether a submission is automated. Resend sends the confirmation email and receives your address to deliver the message. Fonts are served from this site, not from a third party.

Each email carries a confirm link and a remove link. The remove link deletes your address from the list immediately, with no need to write to us.

Cookies and analytics

This site sets no cookies and runs no analytics. Turnstile may set its own cookie under Cloudflare's policy.

How long

Until launch invitations are complete or you ask for deletion, whichever comes first. The list is deleted within 90 days of public launch.

Deletion

Email [email protected] from the address on the list; that is how we check it is yours. The row and any exported copy are deleted within 7 days and you get a one-line confirmation. Database backups expire on their own 30 days later.

Who

GrindOS is a Spark & Wonder Labs LLC product, St. Petersburg, Florida.
