What we collect, and when
If you join the waitlist:your email address, plus a short attribution note about how you found us (the referring site's hostname or campaign tags in the link you clicked). That's the whole record.
If you join using someone's referral link, or share your own: every waitlist signup gets its own referral code and link. If you sign up through a friend's link, we store which code referred you, so we can move both of you up the list — that's the only thing this connects to your email. We don't use it for anything else, and it's never linked to any other data about you.
If you answer the optional one-tap question after signing up(your biggest focus challenge): your answer is stored anonymously. It is not linked to your email or to you, and we couldn't connect it back to you if we tried.
If you just browse: we use cookieless, privacy-focused analytics (Vercel Web Analytics) that count page views in aggregate. No cookies, no cross-site tracking, no advertising identifiers, and nothing that identifies you personally.
Briefly, in server memory:your IP address is used to rate-limit our signup endpoints so they can't be abused. It is held in memory only and is not written to our database or logs as part of your record.
What we use it for
Your email is used to send you what you signed up for: the Clean Focus Stack Guide, occasional product updates, and ingredient research from The Signal. The anonymous demand-signal answers guide what we build and write. That's it.
What we never do
- We do not sell, rent, or trade your email or any other data.
- We do not run advertising trackers or third-party ad pixels on this site.
- We do not use cookies for tracking.
- We do not send daily emails, and unsubscribing is honored immediately.
Where your data lives
The site runs on Vercel, and our waitlist database runs on Railway. Emails are sent through Resend, our email service provider, which processes your address solely to deliver our messages and, if you're on the list, keep you in our contact audience there. Analytics are processed by Vercel Web Analytics, which is cookieless and does not store personal information. These providers act on our instructions; none of them may use your data for their own purposes.
If we ever turn on an additional integration to route new signups to another tool (for example, a marketing platform via Zapier or a similar service), that will only ever receive your email, attribution source, and signup time — never anything else — and this page will be updated first to name the specific tool before it goes live.
Your choices and rights
Every email we send includes a way to unsubscribe, and you can also just ask. To unsubscribe, or to have your email permanently deleted from the waitlist, contact hello@signalstatelabs.comand we'll confirm once it's done. Depending on where you live (including under Canadian privacy law, the GDPR, and California's CCPA), you may also have formal rights to access, correct, or delete your personal information — the same email address is the way to exercise them.
Changes
If our data practices change, this page changes first, with a new date at the top. We won't quietly expand what we collect.
