What we collect (and what we never will)
The complete inventory of Tarsier's data collection, in plain words. Spoiler: the second list is longer.
In this note
Most privacy pages are where candor goes to die. Ours is a list, because lists are checkable. Here is everything Tarsier records about a visit:
- The page viewed. Rather the point of the exercise.
- The referrer and your own campaign tags, so you know what worked.
- A country, city, and region, derived at the network edge. Never a precise location, never an address.
- Browser and device type. Categories, not fingerprints.
- Events you explicitly define: signups, purchases, button clicks.
And the longer list
- No cookies. Of any kind. For any reason.
- No fingerprinting, probabilistic or otherwise.
- No names, emails, or account data.
- No stored IP addresses.
- No cross-site tracking of any description.
“The strongest security posture is having little worth stealing.”
The only cookie in the entire system is the login session for your own dashboard — your visitors never see it. That is the whole inventory. If it ever grows, this post gets an update and you get told first.

Small footprint. Big eyes. Always watching — and occasionally writing it down.
