Earth seen from orbit over the South Atlantic, ringed by a dense shell of satellites. Two satellites on crossing orbits collide, and trails of orange debris stream ahead along both orbits.

Privacy

This page describes what Kessler@home stores about you and what it publishes.

What we store

  • Account: your email address, the name you choose, an account key, and optionally a country and a web URL. Your email address is never shown publicly.
  • Computers: for each computer attached to the project, the details BOINC reports: its name, CPU and GPU model, memory, disk space, network speed, operating system and time zone, its IP address, and a log of the tasks it has run.
  • Forum activity: posts, private messages and preferences, if you use the message boards.

Spam checks

When you create an account or change your email address, the address and your IP address are checked against StopForumSpam, a public database of addresses used by spammers, to keep spam accounts out of the message boards. Nothing else is sent to it.

Creating an account, creating or editing a profile and creating a team also show Google's reCAPTCHA check ("I'm not a robot"). To tell people from automated programs, reCAPTCHA sends Google information about your browser and how you use the page, and Google may set its own cookies for it. Google's Privacy Policy and Terms of Service apply to it.

What is public

Like all BOINC projects, we publish statistics: your account name, country, team, credit totals and your computers' hardware details (not their IP addresses or names). They are exported daily as XML files used by cross-project statistics sites. You can hide your computers from your public profile in your project preferences.

What the application does on your computer

The application simulates the debris population and nothing else: it reads its input files, writes its results and checkpoints in the folder the BOINC client gives it, and makes no network connections of its own (the BOINC client does all the downloading and uploading).

Cookies

A cookie keeps you logged in. If you choose a light or dark appearance under Site > Appearance, a second cookie, kh_theme, remembers that choice; it holds only the word "light" or "dark". BOINC's own pages set a few more for the same purpose: your choice of language, the order in which you sort forum threads, and a short-lived one while you create an account. The site sets no advertising or analytics cookies.

Deleting your account

You can delete your account from your account page; the request is confirmed through a link sent to your email address. Deleting it also deletes your forum posts, your private messages and the records of your computers. Credit already granted stays in the aggregate statistics without your name.
