The short version
- The public site sets no cookies: no advertising cookies, no tracking cookies, no analytics cookies.
- Our analytics are first-party and cookieless, and store nothing in your browser.
- The only cookies we set are strictly necessary session cookies for our own staff when they sign in.
- Everything a page loads, fonts included, comes from our own server, so no third party can set a cookie through it.
Because we set no cookies on visitors that are not strictly necessary, we do not show a cookie banner. There is nothing to accept or decline.
Visitors to the public site
Browsing our pages, reading the blog, using the free tools or sending the contact form does not set a cookie. We run no advertising pixels, retargeting tags, social media widgets or third-party analytics, so no one else sets cookies through our pages either.
Some free tools, such as a checklist, may remember your progress in your browser's local storage so it is still there when you come back. That data never leaves your device, we cannot see it, and clearing your browser's site data removes it.
Analytics without cookies
To count visitors without identifying anyone, our server combines each visitor's IP address and browser details with a random value that is replaced every day, and keeps only the resulting one-way code. Nothing is stored in your browser, and because the daily value is deleted, the code cannot follow you from one day to the next. The privacy policy describes exactly what is recorded and for how long.
Staff sign-in
Our own staff sign in to a private console. Signing in sets a session cookie that keeps them signed in. It is strictly necessary for that purpose: it cannot be read by page scripts (it is "HttpOnly"), it is sent only over HTTPS in production, and it contains a random token rather than any personal information. It expires after 3 days, or sooner when they sign out. The staff console also keeps a few display preferences, such as whether the sidebar is open and the colour theme, in local storage.
If you are not one of our staff, none of this is set in your browser.
Everything we store in your browser
| Name | Type | Who gets it | Purpose | Duration |
|---|---|---|---|---|
__Secure-better-auth.session_token (better-auth.session_token without HTTPS) | Cookie, strictly necessary | Signed-in staff only | Keeps a staff member signed in to the console | 3 days, renewed at most daily while in use; removed on sign-out |
Other better-auth.* cookies | Cookie, strictly necessary | Staff, while signing in | Short-lived security values our sign-in software may set during the sign-in process | Session or minutes |
alumic.admin.* and similar console keys | Local storage | Signed-in staff only | Console display preferences, such as sidebar state and theme | Until cleared |
alumic:tools:* | Local storage | Anyone using a tool that saves progress | Remembers your answers in that tool on this device only; never sent to us | Until cleared |
Analytics appear nowhere in this table because they store nothing in your browser.
Your choices
You can block or delete cookies and local storage in your browser's settings. Doing so will not affect the public site at all; for staff, blocking cookies prevents signing in.
