What we use today
We set no cookies at the moment. We use your browser’s local storage for the two items below. Both are on your device only and neither identifies you.
| Name | What it does | Type | How long |
|---|---|---|---|
| sumlark-theme | Remembers whether you chose the light or dark theme | Essential (a setting you chose) | Until you clear your browser data |
| sumlark-consent | Remembers your cookie choice, so we do not ask on every visit | Essential (records your choice) | Until you clear your browser data, or until we ask again after a change |
Optional cookies
We may add two kinds of optional cookie. Neither is in use yet, and none will be set unless you accept it.
- Analytics: help us see which pages are used so we can improve them.
- Advertising: let us show advertising that helps keep the calculators free. Advertising providers (such as Google) may use cookies to show and measure ads.
Our host
Our website is delivered by Cloudflare. Hosting and security providers can use strictly necessary cookies to protect a site from attacks. These do not need your consent. If we see any, we will list them in the table above.
How to change your choice
You can review or change your choice at any time with the button below or the “Cookie settings” link in the footer of every page. Choosing “Reject all” is as easy as “Accept all”, and rejecting does not stop any calculator from working.
You can also delete or block cookies and local storage in your browser settings. The ICO explains how. If you clear your browser data we will ask for your choice again.
