What teleionlabs.com, Tessera and Tessera's model shim keep, and for how long. Updated November 2, 2026.

This site

teleionlabs.com has no accounts, no cookies, no analytics scripts and no ads, and it stores nothing in your browser.

The live status on the home and status pages is read by our server, so your browser talks only to teleionlabs.com.

Cloudflare runs the site. It keeps the site's request logs for 3 days: the page asked for, the answer, your internet address, your browser's name and a rough location.

Tessera without an account

A free session gets its own practice space. What it saves, and the record of what it did, are deleted after 24 hours.

Tessera counts requests by network address to keep free use fair, and its audit record notes the name of your software. It keeps both as a keyed one-way value that changes every day, not the address or the name itself.

Cloudflare also keeps the request logs of Tessera and Tessera's model shim for 3 days, with the same details as this site's.

Tessera's model shim

The free preview calls no model and saves nothing.
