This Cookie Notice explains what cookies and similar storage technologies klim.expert uses, why, and how you can opt out. It supplements the Privacy Policy, which is the canonical document covering how I handle personal data overall.
TL;DR
- This site does not use cookies for analytics. It uses
localStorageinstead, with a single key, for session attribution. - It loads Google Tag Manager / Google Analytics 4 — those do set cookies if you let them. You can block them at the browser level.
- When paid Google Ads are running, Google Ads conversion tracking and remarketing tags may set additional cookies. The list below is updated whenever I add or remove a tag.
- I do not sell or rent any of this data.
What is "browser storage"
Two storage mechanisms are relevant here:
- Cookies — small files saved by your browser, sent back to a server on every request to that domain. Long-standing tech, used by analytics and ad platforms.
- localStorage — a key/value store that stays in your browser. Never sent to a server unless JavaScript on the page reads it and explicitly forwards it. Statio uses this; cookies are not involved.
What klim.expert sets directly
| Storage | Key / name | Type | Purpose | Lifetime |
|---|---|---|---|---|
localStorage | statio-s | session token | Anonymous attribution across pageviews so I can see which entry page led to which actions, without a cookie. The token is a random UUID, not linked to your identity. | Until your browser clears site data, or 30 days of inactivity (whichever first). |
localStorage | klim-theme | preference | Remembers your light/dark theme choice on this site. | Until cleared. |
Neither of these is a tracking cookie. Neither is shared with third parties. Both can be wiped by clearing your browser's "site data" for klim.expert.
What third-party services may set
These services run on every page and set their own cookies under their own domains. I list them so you know who they are and can opt out at the source.
| Service | Provider | Purpose | Cookie domain |
|---|---|---|---|
| Google Tag Manager | Google LLC | Loads measurement tags below. | google.com / googletagmanager.com |
| Google Analytics 4 | Google LLC | Aggregate visit counts, sources, pages. | google.com / googletagmanager.com |
| Google Ads conversion tracking | Google LLC | Records when a Google-Ads visitor submits the contact form (only active during paid campaign windows). | doubleclick.net / google.com |
| Google Ads remarketing | Google LLC | Allows Google Ads to show ads to past visitors on other sites. (Only active during paid campaigns.) | doubleclick.net / google.com |
| Knowster.chat AI widget | Knowster | Persists conversation state if you actually open the chat. Inactive otherwise. | knowster.chat |
You can opt out of Google's tracking on this site with the Google Analytics opt-out browser add-on or by blocking third-party cookies in your browser. You can opt out of Google Ads personalisation at adssettings.google.com.
How to control storage
Every modern browser lets you:
- View, delete, and block cookies per site.
- Clear localStorage along with cookies.
- Block third-party cookies entirely.
- Run in Private / Incognito mode (storage is wiped at session end).
Quick links:
Blocking cookies and storage will not break this site — it will only suppress analytics signals on my end.
Do Not Track
This site does not currently honour the legacy DNT header (it has been deprecated by most browsers). Privacy-respectful tracking is the default regardless: no fingerprinting, no cookies for first-party analytics, IP hashed for bot detection only.
Changes
When I add or remove a tag I update the table above and bump the "Last Updated" date.
