What this site stores on your device
This site uses one cookie and a few small items of browser storage. There are no advertising, social media or third-party analytics cookies. Optional items are only stored after you say yes, and you can change your mind at any time.
Complete list
“Preferences” items fall back to a temporary tab-only store (session storage) if you do not allow them.
| Name | Type | Category | Purpose | Lasts |
|---|---|---|---|---|
if_consent | Cookie (first-party) | Strictly necessary | Remembers your cookie choice so the banner does not reappear (for example p1a0v2026-10) | 180 days |
if-consent | Local storage | Strictly necessary | Your choices as a small record: version, random ID, preferences yes/no, analytics yes/no, timestamp | Until you change them or the consent version changes |
if-cid | Local storage | Strictly necessary | A random identifier that links your choice to the consent record I must keep as proof | Until you clear site data |
if-theme | Local storage, or session storage if not allowed | Preferences | Remembers light or dark mode | Until cleared (local); tab session (session) |
if-checks | Local storage | Preferences | Remembers the action steps you tick on an article | Until cleared |
if_admin | Cookie, HTTP-only, path /admin | Strictly necessary | Keeps the site owner signed in to the administration area. Never set for visitors. | Up to 12 hours |
Analytics without cookies
If you accept “Anonymous analytics”, your browser sends a small message to this site’s own server when a page loads or a call-to-action is clicked. It contains the page path, the referring site’s hostname and a device type. It sets no cookie, stores no IP address and no identifier, and nothing leaves my server. Records are deleted after 13 months. If you decline, nothing is sent.
Changing your choice
Use here, or in the footer of any page. Saving new choices replaces the old ones, and I keep a dated record of each change. You can also delete the items above in your browser’s settings; the banner will then appear again.
Strictly necessary items do not need consent because the site cannot work, or your choice cannot be remembered, without them.
Consent records
Each time you save a choice, the site stores in its database: the random ID, your choices, the action (accept all, essentials only, custom, withdraw), the consent version, a hash of your IP address and your browser’s user-agent text. These records are kept for 36 months. See the privacy policy for details.
