Privacy Policy

Last updated August 16, 2026

This page explains, plainly, what happens with your data when you visit stacklinestudio.com. This is a simple site with no accounts and no newsletter, so there isn't much to explain — but here it is in full.

Analytics

This site uses Vercel Web Analytics to see aggregate visit counts and which campaigns (utm_source/utm_medium/utm_campaign) are actually driving traffic. It's cookieless and doesn't track you across other sites.

Clicking the "Get it on Gumroad" button also fires a custom gumroad_click event, carrying whatever UTM parameters were on the page at the time, so I can see click-throughs toward a purchase alongside plain visits. Neither of these collects your name, email, or any other personally identifying information.

Error tracking

This site uses Sentry to catch bugs. If something breaks while you're using the site, Sentry records the error along with technical context — your browser, device, the page URL, and your IP address — so I can reproduce and fix it. That data is used only for debugging, never for marketing or profiling.

Purchases

Clicking "Get it on Gumroad" takes you to Gumroad's own site to complete your purchase. Stackline Studio never sees or stores your card details — Gumroad handles checkout, receipts, and payment processing under its own privacy policy.

No selling, no newsletter, no accounts

  • Your data is never sold, rented, or shared for advertising.
  • There's no login, no user accounts, and no newsletter signup on this site.
  • The only way I get your email address is if you send it to me directly.

Changes

If this policy changes as the site changes, I'll update this page — there's no separate mailing list to notify, since there isn't one.
