Cookie Policy
UntangleTools uses exactly three types of cookies. Here's what each one does, why it exists, and what it categorically does not do.
What are cookies?
Cookies are tiny text files that a website places in your browser when you visit. Think of them as a sticky note your browser keeps on the site's behalf — nothing more. They can't run code, can't access other files on your device, and they only talk to the domain that set them.
Websites use cookies for two broad reasons: functional ones (remembering your settings so you don't have to reconfigure them every visit) and analytical or advertising ones (understanding how the site is used or funding it through ads). We use both — and we tell you exactly which ones below.
Google AdSense
how the ads work
Who sets the cookie
Google LLC, operating under google.com and doubleclick.net — not UntangleTools. When an ad loads on our pages, Google's servers communicate directly with your browser and set their own cookies. We are the publisher; we have no write access to those cookies.
The DoubleClick cookie (IDE)
Google's primary ad-delivery cookie is named IDE and lives under doubleclick.net. It records ad impressions and clicks to prevent you from seeing the same ad on a loop, measure ad effectiveness, and — if you haven't opted out — personalise ads based on sites you've visited previously.
Personalisation & your options
By default, Google may show you personalised ads. You can turn this off at any time by visiting Google's Ad Settings at g.co/adsettings — no account required. You can also opt out of interest-based ads industry-wide at aboutads.info.
Why we use AdSense
Every tool on UntangleTools is free, and we intend to keep it that way permanently. AdSense revenue is our only income stream. Ads fund the infrastructure, the time spent building and maintaining tools, and new features. Blocking ads is your right — but they're how we keep the lights on.

What we categorically
do not do
We never collect your name, email, or any personally identifiable information via cookies
We never store conversion inputs, token text, color codes, or calculation results server-side — all tool computation is 100% client-side
We never sell, rent, or share cookie data with any party other than Google AdSense (described above)
We never fingerprint your device or build a shadow profile of your behaviour across sessions
We never use cookies to gate features — everything works even if you block non-essential cookies
Your control options
Browser settings
Every modern browser lets you block, delete, or audit cookies from Settings → Privacy → Cookies. Blocking all cookies will not break any UntangleTools converter — every tool runs 100% client-side with no server dependency.
Opt out of ad personalisation
VisitGoogle Ad Settingsto turn off personalised ads, or use the industry-wide opt-out ataboutads.info. Ads will still appear, they just won't be tailored to you.
Clear your theme preference
To erase your saved theme, open your browser's developer tools (F12), go to Application → Local Storage → untangletools.com, and delete the untangle_theme key. On your next visit the site loads with the default theme.
Your GDPR rights (Articles 15–22)
If you are in the EU or EEA, you have the right to:
To exercise any of these rights, email us at support@untangletools.com. Because we hold essentially no personal data, most requests will be resolved immediately. You also have the right to lodge a complaint with your local Data Protection Authority — find yours at edpb.europa.eu.
Policy updates
Last updated: May 2026We may revise this page if we add new tools that change how cookies are used, if Google updates its AdSense cookie behaviour, or if applicable privacy regulations require disclosure updates.
We will update the "Last updated" date at the top of this page whenever we make a material change. We recommend checking back periodically. We will not make changes that reduce your privacy rights without prominent notice.

TL;DR: We use Vercel Analytics (anonymised, no personal data), a localStorage key for your theme preference (never leaves your device), and Google AdSense (third-party, personalised ads, opt-out available). That's it. No tracking profiles. No data sales. All tools work client-side.
