Cookie Policy
What this site stores in your browser, what it is for, and how to change your decision.
Last updated: 12 August 2026
Strictly necessary storage
These three items are saved in your browser's local storage rather than as cookies, which means they are never sent to a server — not even to ours. They hold no identifier and cannot be used to recognise you. They are set regardless of your cookie choice, because without them the site cannot remember the settings you selected.
| Name | Purpose | Kept |
|---|---|---|
| theme | Remembers whether you chose light, dark or your system setting, so the page does not flash the wrong colours on every visit. | Until you clear your browser storage |
| region | Remembers the region you selected, so tools start with the right units, currency and conventions. | Until you clear your browser storage |
| consent | Records your answer to the cookie banner, so you are not asked again on every page. | Until you clear your browser storage |
Analytics and advertising cookies
None are set at present. No analytics or advertising is active on this site today, so no cookies of this kind exist. What follows describes what would happen if that changes.
These are set only if you accept them. They come from Google, which uses them to measure how the site is used and to serve and measure advertising. If you decline, the scripts that set them are never loaded, so the cookies are never created.
Google publishes its own list of the cookies it uses and how long they last. Because the exact set depends on which Google services are active, we link to their documentation rather than reproduce a list here that could quietly go out of date.
Your current choice
You can change your decision at any time. It takes effect immediately, and declining after previously accepting stops any further data being collected.
Nothing to configure
Clearing everything
Clearing site data in your browser removes all of the above, including your theme and region preferences. The site will ask about cookies again on your next visit.
More detail
The Privacy Policy explains what happens to the data you enter into the tools, which is the shorter answer: nothing leaves your device.
