Privacy
StackTab has no accounts, no sign-in and nothing to buy, so there is very little to say here.
What is collected
Anonymous usage analytics — page views, and which parts of the tool get used — through PostHog, proxied through this domain. No account is created because there are no accounts. Form inputs are masked in session recording.
Session recordings
Analytics here includes session replay: a reconstruction of how a page was used — clicks, scrolls, pointer movement, and which pages were opened in what order. Everything typed into a field is masked in the browser before it is sent, so text you enter is never captured. It exists so that a flow which breaks for someone can be watched back and fixed rather than guessed at. Recordings are processed by PostHog and deleted after 30 days.
What is not collected
Nothing you type into the picker or the calculators is sent anywhere. Those run entirely in your browser against data the page already loaded; the numbers you enter never leave the device.
Third parties
The site is hosted on Vercel and its catalogue is stored on Supabase. Links to vendor pricing pages are marked nofollow and go directly to those vendors; what they do once you arrive is covered by their own policies.
