Cookie Policy.

Exactly what UtiBox stores in your browser, and why. It’s a short list.

Effective 9 November 2026 Version 1.11 11 min read

The short version

In shortOne strictly necessary cookie of ours, a couple of small preference cookies, a little local storage, Google’s advertising cookies, and Google Analytics, Ahrefs Web Analytics and Microsoft Clarity.
  • We set one essential cookie, ubsid. It’s strictly necessary: without it forms can’t be protected against forgery.
  • If you use the light/dark switch, a second cookie, ub_theme, remembers your choice. It’s only set when you press the switch, and it holds just the word “light” or “dark”.
  • Your browser’s local storage keeps your watchlist, your recently used tools and a few preferences. It stays on your device.
  • Ads are served by Google AdSense, and Google and its partners use cookies to show and measure them. Where the law requires it (for example in the EEA, the UK and Switzerland), those cookies wait for your consent.
  • Google Analytics shows us how the site is used, with its own cookies (_ga). In the EEA, the UK and Switzerland it stores nothing until you agree.
  • Ahrefs Web Analytics counts visits without cookies: it stores nothing in your browser and doesn’t keep your IP address.
  • Microsoft Clarity records how pages are used (clicks, scrolling) for heatmaps and replays, with its own cookies. It blanks out the tool area and what you type, and we don’t use it in the EEA, the UK or Switzerland.
  • We use no tracking pixels, social widgets or fingerprinting.

What we keep in your browser

In shortA guest watchlist, recent tools and tool settings, saved in local storage on your device and never sent to us.

ub.*Settings for individual tools: for example the password generator’s options, your typing-test best score, or a draft in the word counter.Everyone
ubdp-histThe share of resolvers that had the update at each of your DNS propagation checks (up to 30 checks for each of your 20 most recent domains and record types), drawn as the propagation chart. Never sent to us.Everyone who uses the DNS propagation checker

Local storage isn’t a cookie: it isn’t sent with requests, and we can’t read it from our server. It stays until you clear it.

Advertising cookies (Google)

In shortGoogle AdSense serves our ads and sets its own cookies to show, limit and measure them. You can say no, and turn off personalised ads.

Ads on UtiBox are served by Google AdSense. When an ad loads, Google and its advertising partners may set or read cookies (for example __gads and __gpi on utibox.io, and IDE on doubleclick.net) and use similar technologies. They use them to show ads, limit how often you see the same ad, measure results and fight fraud, and, with your consent, to personalise ads based on your visits to UtiBox and other websites.

The small map of where a website is hosted, on WHOIS Lookup, is a Google Maps frame. Google may set or read its own cookies in that frame, under Google’s cookie policy; we can’t read them.

The map on IP Address Lookup is a Google Maps frame. Google may set or read its own cookies in that frame, under Google’s cookie policy; we can’t read them.

The map on Reverse DNS Lookup is a Google Maps frame. Google may set or read its own cookies in that frame, under Google’s cookie policy; we can’t read them.

On tools that run on our server, Google reCAPTCHA v3 checks in the background that requests come from a person rather than a script. Google may set or read its own cookies and similar storage for this (for example _GRECAPTCHA), under Google’s cookie policy; they’re needed to protect the site from abuse, and we can’t read them. Pages that run entirely in your browser don’t load it.

The map on What Is My IP is a Google Maps frame. Google may set or read its own cookies in that frame, under Google’s cookie policy; we can’t read them.

  • Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
  • Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to UtiBox and/or other sites on the internet.
  • You can opt out of personalised advertising in Google’s Ads Settings, and opt out of other vendors’ personalised advertising at aboutads.info or youronlinechoices.eu.
  • UtiBox is free because of ads, so advertising is always on. Our cookie notice tells you about it on your first visit, and “Ads & cookies” at the bottom of every page shows the details again.
  • In the EEA, the UK and Switzerland, Google’s consent message asks for your choice before ad cookies are used (it’s switched on when ads go live). If you don’t agree, Google still shows ads, but they aren’t personalised.

These cookies belong to Google and its partners, not UtiBox, and are covered by Google’s cookie information and Privacy Policy. Ads never appear in the admin area.

Analytics cookies (Google Analytics)

In shortGoogle Analytics shows us which pages and tools people use. In the EEA, the UK and Switzerland it stores nothing until you agree.

We use Google Analytics 4 to understand how UtiBox is used: which pages and tools are opened, how people arrive (for example from a search engine or another site), and the type of browser and device. It helps us decide what to fix and build next. Google Analytics sets these cookies on utibox.io:

CookieWhat it doesKept for
_gaTells one visitor’s visits apart from another’s with a random number. It doesn’t contain your name, email or IP address.Up to 2 years
_ga_0JM0498TPLKeeps track of the current visit (session) for the same property.Up to 2 years
  • In the EEA, the UK and Switzerland, these cookies are set only if you agree in Google’s consent message. Until then Google Analytics stores nothing on your device and receives only signals without cookies or identifiers, so your visits can’t be linked together.
  • Google Analytics doesn’t log or store IP addresses; Google uses them only to work out a rough location (country and city) and then discards them.
  • To opt out of Google Analytics on every site, install the Google Analytics opt-out browser add-on. You can also block or delete the cookies in your browser.

These cookies belong to Google and are covered by how Google uses information from sites that use its services and Google’s Privacy Policy. Analytics never runs in the admin area.

Cookieless analytics (Ahrefs)

In shortAhrefs Web Analytics counts visits without cookies or local storage, and never stores your IP address.

We also use Ahrefs Web Analytics to count visits and see which pages people open and how they arrive. It sets no cookies and stores nothing in your browser, so there’s nothing of it to find or clear in your cookie settings. When a page loads, your browser sends Ahrefs the page address and title, the page that sent you, your language and your screen size, and Ahrefs reads your browser and device type from the request. When you click a link or send a form, it records where the link goes or where the form is sent, never what you type.

  • To count each visitor once a day, Ahrefs combines your IP address and browser details with a random value that it deletes and replaces every 24 hours, so your visits can’t be linked from one day to the next.
  • Ahrefs uses your IP address to work out your country and city, then discards it. The address is never stored.
  • Because it stores nothing on your device, we use it for every visitor, including in the EEA, the UK and Switzerland.
  • To opt out, block scripts from analytics.ahrefs.com in your browser or with a content blocker.

This data is processed by Ahrefs and covered by the Ahrefs Privacy Policy. Analytics never runs in the admin area.

Usage recordings (Microsoft Clarity)

In shortMicrosoft Clarity shows us where people click and scroll, with tool areas blanked out. We don’t use it in the EEA, the UK or Switzerland.

We use Microsoft Clarity to see how pages are used: heatmaps of clicks and scrolling, and anonymised replays of visits, so we can find what confuses people and fix it. Clarity blanks out what you type into forms and the whole tool area, so it never records your tool input or results. We don’t load Clarity at all for visitors in the EEA, the UK or Switzerland. Elsewhere, Clarity sets these cookies on utibox.io:

CookieWhat it doesKept for
_clckKeeps a random Clarity ID for your browser, so visits can be counted as the same visitor.About a year
_clskJoins the pages of one visit into a single recording.One day

Microsoft may also set its own cookies on its own domains (for example MUID and CLID); see Clarity’s cookie list. Recordings are kept for up to 30 days. These cookies belong to Microsoft and are covered by the Microsoft Privacy Statement. To opt out, block cookies and scripts from clarity.ms in your browser or with a content blocker.

What we don’t use

In shortNo tracking pixels, no social widgets, no fingerprinting.
  • No tracking pixels, social widgets or device fingerprinting.

Our typeface (Geist) is served from our own server, so loading a page doesn’t contact Google Fonts.

If this changes

In shortWe update this page before we add anything new.

If we add other cookies, we’ll update this page and our Privacy Policy first, and anything optional will stay off until you agree where the law requires consent.

How to control it

In shortTurn off personalised ads in Google’s My Ad Center, opt out of other companies’ personalised ads, or clear this site’s data in your browser.

Ads stay on, because they pay for UtiBox. You control how they’re personalised: turn off personalised ads in Google’s My Ad Center, and opt out of other companies’ personalised ads at aboutads.info or youronlinechoices.eu. In the EEA, the UK and Switzerland, “Ads & cookies” at the bottom of every page reopens Google’s consent message so you can change your answer.

To opt out of Ahrefs Web Analytics, block scripts from analytics.ahrefs.com in your browser or with a content blocker. It stores nothing on your device, so there’s nothing of it to clear.

To opt out of Microsoft Clarity, block cookies and scripts from clarity.ms in your browser or with a content blocker.

To opt out of Google Analytics, install the Google Analytics opt-out browser add-on. In the EEA, the UK and Switzerland, Google Analytics also follows your answer in Google’s consent message.

You can delete the cookies and everything in local storage by clearing this site’s data in your browser’s settings. You can also block cookies for utibox.io, but then some forms won’t work. Clearing local storage removes your watchlist and your tool settings for good, because we don’t keep a copy.

Cookies on UtiBox

UtiBox is free because of ads. Google and its partners use cookies to show, limit and measure ads, Google Analytics, Ahrefs Web Analytics and Microsoft Clarity show us how the site is used, and we use a few essential cookies to run the site.
