Privacy notice

How we handle your email.

The only personal data we collect right now is the email address you give us so we can tell you when Sumsight launches. This page covers what we do with it.

Last updated: 2026-04-29.

What we collect

Your email. Nothing worth a profile.

The email address you submit, the date you signed up, and the wording you agreed to. We also keep your IP and browser at the moment of signup as proof of consent under GDPR. We do not collect names, locations, or anything else.

Why we have it

To send you one email.

When Sumsight launches on the Mac App Store, we'll send you one message announcing it. That's the entire purpose of this list. We don't sell, share, or enrich your email with third-party data. A delivery provider helps us send the message; they don't use it for anything else.

How long we keep it

Until the launch email goes out, or until you ask us to remove you.

Whichever comes first. Pending signups that never confirm are deleted after 30 days.

Your rights

You can leave at any time.

Click the unsubscribe link in any email we send and you're off the list immediately. To request your record be fully erased, write to hello@sumsight.app — we'll handle it within 7 days.

No tracking

No cookies, no analytics, no trackers.

The only network requests your browser makes from this site are to sumsight.app itself, and to Google Fonts for the Inter typeface (loaded under their privacy policy).

Who we are

The Building Blocks Co.
