What this site keeps.

Updated 2026-09-21

If you ask for launch updates

GrainSage stores the email address you enter, the time you entered it, and which form you used. That is the whole record. It is used for one email when GrainSage launches, and nothing else.

What the site does not keep

The site sets no cookies of its own, runs no analytics, and makes no request to a third party. The network address of a submission is used only to limit repeated tries and is not stored. Your name is never asked for.

Where the record lives

In a Cloudflare D1 database in GrainSage’s Cloudflare account, alongside the site itself.
