Cookie Notice

Effective October 13, 2026 · Last updated October 13, 2026

The short version

  • One cookie, to keep you signed in to the app. That's all.
  • No analytics, advertising or tracking cookies, on either site.
  • Because the only cookie is strictly necessary, there's no cookie banner to click through.

Cookies

NameWherePurposeTypeLasts
xde_sessionapp.xybernetex.comKeeps you signed in after you use a sign-in link. It holds a random identifier; we store only a hash of it. Strictly necessary, first-party. HttpOnly (page scripts can't read it), Secure (sent only over HTTPS), SameSite=Lax.30 days, or until you sign out

xybernetex.com, the product site, sets no cookies at all.

Things the app keeps in your browser

The app saves a few things in your browser's local storage so it remembers where you were. They stay on your device: they aren't sent with requests and aren't used to track you. Clearing your browser's site data removes them.

KeyWhat it remembers
wizard.v1The Wizard question you're working on and your answers so far, so a refresh doesn't lose them
wizard.optsYour Wizard options (quick or thorough, research on or off)
lab.layout, lab.liveOpen, lab.showAllHow you've arranged the Lab: the layout, whether the live card is open, and whether every tool is shown
lab.autobuilt.<id>That a decision's numbers were already built automatically once, so it doesn't happen again
lab.meOnly on servers without accounts: the name you typed for sign-offs

Other companies

Our pages load typefaces from Google Fonts, and the app loads open-source code, such as its text editor, from jsDelivr and cdnjs. These requests don't set cookies, but those providers receive your IP address and browser details when the files load. Their privacy policies apply to that.

Our domain name service is provided by Cloudflare. If we later route traffic through Cloudflare's network for protection, Cloudflare may set strictly necessary security cookies (such as __cf_bm, which tells people from bots). We'll list them here if we do.

Your choices

You can block or delete cookies in your browser settings. If you block xde_session, you won't be able to stay signed in to the app. Since we don't use optional cookies, there's nothing else to switch off.
