Praeco is a personal project, still being built. It changes often, it has rough edges, and parts of it will behave differently next month. That applies to this page too — if what it says ever stops matching what the extension does, the extension is the thing that moved, and this page will be corrected.
What is not provisional is the list below. Collecting less is not a feature that gets added later, and nothing here will quietly start collecting more.
The extension collects no personal information, shows no ads, contains no analytics or tracking of any kind, and sends nothing to anyone except the two places it exists to talk to: csfloat.com, and the Praeco server you chose to sign in to. Nothing is ever sold, shared or transferred to a third party.
All of this is Chrome's own extension storage on your computer. None of it leaves your machine except where stated.
| What | Why | How long |
|---|---|---|
| Your Praeco sign-in token and Steam ID | Scans are written to the server under your account, so the server has to know who is writing. The token is sent only back to the site that issued it, and to no other address. | Session storage — erased when the browser closes |
| The scan in progress | So a run survives closing the page, switching tabs or the browser putting the extension to sleep. Skin names, wear brackets and counts. | Until the run finishes or is stopped |
| A rate-limit deadline | When CSFloat asks for a pause, every part of the scan has to respect the same deadline. A timestamp, nothing else. | Session storage — erased when the browser closes |
| The address of the site you signed in to | So the extension answers that site and refuses instructions from any other page. | Until changed |
| A cached list of CS2 skin names and their numeric IDs | Public game data, fetched once a day from ByMykel's open CS2 API, so a scan can turn "AK-47 | Redline" into the ID CSFloat's database page uses. Contains nothing about you. | 24 hours |
tabs permission is used to open and close one hidden
csfloat.com tab and to read the count off that tab — Chrome describes
this as "read your browsing history" in the install prompt, which is the
warning attached to that permission, not a description of what this does.Uninstalling the extension deletes everything above with it. Data you have already contributed to a Praeco server lives on that server; ask its owner to remove it.
This is an independent tool that works with csfloat.com. It is not made by, endorsed by or connected with CSFloat, and uses no CSFloat account except the API key you enter yourself.
