Cookie Policy
This page explains which cookies and similar storage hexrgb.com uses, who sets them, and how you can opt out — both on this site and across the web.
What is a cookie?
A cookie is a small text file that a website asks your browser to store. The next time you visit, the browser sends the cookie back, which lets the site remember things between page loads — for example, that you've already dismissed a notice, or that you previously visited from a particular ad. Similar technologies, such as localStorage and tracking pixels, work the same way for the purposes of this policy.
Cookies set by hexrgb.com
The site itself sets very few first-party cookies. The color tools work entirely in your browser; the URL hash that mirrors your current color (for example #6C5CE7) is not a cookie and is never transmitted to the server.
Cookies set by third parties
The two main third parties whose cookies you may encounter on this site are Google Analytics and Google AdSense. Categories and typical examples:
Analytics cookies
| Cookie | Set by | Purpose | Typical lifetime |
|---|---|---|---|
_ga | Google Analytics | Distinguishes unique users. | Up to 2 years |
_ga_<ID> | Google Analytics 4 | Persists session state for a specific property. | Up to 2 years |
Advertising cookies
| Cookie | Set by | Purpose | Typical lifetime |
|---|---|---|---|
__gads | Google AdSense | Measures ad performance and frequency-caps ads. | Up to 13 months |
__gpi | Google AdSense | Stores ad personalisation and consent signals. | Up to 13 months |
IDE / NID / ANID | Google / DoubleClick | Used to deliver, target, and report on ads across the Google ad network. | Up to 24 months |
| Other partner cookies | Google's authorised ad partners | Selected at auction time; may include measurement, frequency capping, or interest-based targeting. | Varies |
Cookie names and lifetimes are set by the respective providers and can change over time. The list above describes typical examples and is not exhaustive.
Why advertising cookies are used
Advertising cookies allow Google AdSense and its partners to:
- Limit how often you see the same ad ("frequency capping").
- Measure whether an ad was viewable and acted upon ("measurement").
- Select ads believed to be more relevant based on previous browsing on this and other sites ("personalisation").
You can use the site without personalised ads — see the opt-out steps below.
Your choices
Opt out of personalised advertising (recommended)
- Google Ad Settings — toggle off "Personalised ads" at adssettings.google.com. This affects ads served by Google across the web, including on hexrgb.com.
- Industry opt-outs — manage opt-outs across many ad vendors at aboutads.info/choices (US) and youronlinechoices.eu (EU).
- Mobile — on Android and iOS you can reset or limit your advertising ID through device privacy settings.
Opt out of Google Analytics
- Install the official Google Analytics Opt-out Browser Add-on for Chrome, Firefox, Safari, Edge, and Opera.
Block or delete cookies in your browser
Every modern browser lets you block third-party cookies, delete existing cookies, or use private/incognito mode (which discards cookies when the window closes):
Do Not Track
Some browsers send a "Do Not Track" or Global Privacy Control signal. Industry standards on how to honour these signals are still inconsistent. Where required by law (for example, under the CCPA/CPRA), Global Privacy Control is treated as a valid opt-out of the sale and sharing of personal information for cross-context behavioural advertising.
Changes to this policy
This cookie policy may be updated when the cookies in use change or when applicable laws change. The "Last reviewed" date at the top reflects the most recent update.
