Cookie Policy
What this site stores in your browser, why, and how to get rid of it. Right now the tools themselves set no cookies at all — two entries in local storage is the whole of it.
Cookies and local storage are not the same thing
The distinction matters here because this site mostly uses the second one. A cookie is a small file your browser attaches to every request it makes to a site, so the server sees it. Local storage stays on your device and is only ever read by code already running in the page — it is never transmitted.
The site's own preferences use local storage. Cookies appear only when a third-party service that needs them is switched on.
What the site stores by itself
| Name | Type | Purpose | Expires |
|---|---|---|---|
nt_theme | Local storage | Remembers whether you chose the light or dark palette | When you clear site data |
nt_consent | Local storage | Remembers that you dismissed the cookie notice, so it is not shown again. Written only if advertising or analytics is enabled. | When you clear site data |
Neither identifies you, neither is shared, and neither leaves your device. If you use the site without ever changing the theme, nothing is written at all.
Third-party cookies, if and when they are on
Each service below is independent and each is off until an ID is configured for it. Where one is running, it is described here.
Google AdSense
Serves the advertising that funds the site. Google and its partners may set
cookies to limit how often you see the same ad, to measure whether an ad worked,
and to personalise what you are shown. The main ones are __gads,
__gpi and IDE, and they typically last from a few
months to two years. Google is an independent controller of this data; its
advertising
policy governs it.
Google Analytics 4
Counts visits and shows which pages get read. Sets _ga and
_ga_<id>, lasting up to two years, to tell a returning visitor
from a new one. IP anonymisation is enabled in the configuration this project
ships with.
Microsoft Clarity
Records aggregate interaction patterns — where people click and how far
they scroll. Sets _clck and _clsk.
Plausible
Sets no cookies and collects no personal data. It is included as the lightest option for anyone who wants traffic numbers without a consent banner.
Meta Pixel
Optional and off by default. If enabled it sets _fbp and reads
Facebook's fr cookie for advertising measurement.
How to control all of this
- Clear everything this site stored: your browser's “Clear site data” or “Cookies and site data” option for this domain. The site keeps working; it just forgets your theme.
- Block third-party cookies: every major browser can do this in settings, and it stops advertising cookies without affecting any tool here.
- Turn off personalised advertising: Google Ads Settings, optout.aboutads.info, or Your Online Choices in the EU.
- Use an ad blocker: we would rather you did not, but nothing on this site breaks if you do. No tool is gated behind an ad.
Do Not Track
Browsers can send a Do Not Track header. There is no agreed standard for what a site must do about it, so most ignore it. This site sets no tracking cookie of its own in any case; where third-party advertising is enabled, its behaviour is governed by that provider's settings rather than by this header.
Changes
If a service that sets a cookie is added, this table is updated before it goes live. Questions: the contact page.
