Privacy

What Sessyn knows about you

As little as technically possible. Here is the exhaustive list.

Sessyn never collects

None of the following reaches Sessyn infrastructure, by architecture rather than by policy:

  • Browsing history, or any URL you visit
  • Page contents or search history
  • Cookie values, authentication cookies, or session tokens
  • localStorage, sessionStorage, or IndexedDB contents
  • Passwords, form contents, or clipboard contents
  • Advertising or fingerprinting identifiers
  • Your privacy timeline or per-site tracker map
  • IP addresses used for profiling, or precise location

If we are ever technically unable to keep one of these promises, the correct response is to change the architecture — not the wording.

What the websites measure

This site sets no cookies and loads no third-party resources. There are no fonts from a CDN, no tag manager, no social widgets, and no session replay. You can verify all of this in your browser's network tab, which is rather the point.

Where we do measure product usage, it is aggregate and non-identifying: counts of page views and feature invocations, error rates, and coarse platform distribution. No cross-site identifiers, no raw IP retention, no advertising profiles. The implementation is documented publicly, and the full analytics policy is published alongside the source.

What the extension sends

Nothing. The current build makes no network request of any kind: the tracker rules are compiled into it, so there is not even a request for those. Signed rule updates are the designed path and are not live yet. When they ship, that request will reveal that some browser asked for the current ruleset — it will carry no account, no identifier, and no indication of what you were browsing.

Server logs

Serving a web page necessarily involves receiving an IP address. Sessyn does not persist it for profiling: access logs are minimised, IPs are truncated, query strings are redacted, and retention is short. Abuse and security logging is kept separate from any product measurement.

Your rights are mostly moot

Data-subject requests usually ask a company to disclose or delete what it holds about you. In Sessyn's case the honest answer is that there is no record to produce, because no identifier was ever created. If that ever changes, this page changes first.
