Cookie Policy
Last reviewed on 2026-04-30
This page explains the cookies and similar local-storage values that may be set when you visit ComputingPower.org, why each one is used, and how to opt out. Read it alongside the privacy policy.
What is a cookie?
A cookie is a small file that a website asks your browser to store on your device. The next time you visit, your browser sends the file back to the site. Cookies allow basic functions (remembering your consent choices), let analytics tools count returning visits, and let advertising tools measure or personalize ads. Modern browsers also expose related storage mechanisms — localStorage, sessionStorage, IndexedDB — which are treated together with cookies in this policy.
Categories of cookies used on this site
1. Functional
The site itself does not require any login or session, so functional cookies are minimal. Calculator inputs are kept in memory while you use a page; if any input is preserved between visits, it is stored as a localStorage value rather than a cookie and is never transmitted off your device.
2. Analytics
Google Analytics is used to count visits and understand which pages are read. The cookies it sets are first-party cookies under the site's own domain, but the data is processed by Google. Typical analytics cookies include identifiers prefixed with _ga and _gid; Google's documentation lists the full set and their lifetimes.
3. Advertising
When ads are served on the site, Google AdSense and its ad partners may set cookies for ad delivery, frequency capping, fraud prevention, conversion measurement, and — where you have given consent — personalization. Google's standard advertising cookies include identifiers used by the DoubleClick / Google ad services.
Cookies you may encounter
| Cookie / Storage key | Set by | Purpose |
|---|---|---|
_ga, _ga_* |
Google Analytics | Distinguish visitors and sessions for traffic measurement. |
_gid |
Google Analytics | Distinguish visitors over a 24-hour period. |
NID, IDE, ANID, __gads, __gpi |
Google AdSense / Google ad services | Ad delivery, ad frequency capping, fraud detection, and (with consent) personalization. |
| Various | Hosting CDN | Routing, caching, and abuse protection. These are usually short-lived. |
Cookie names and lifetimes can change without notice as Google and the CDN vendor update their products. The list above reflects what is current at the time this page was reviewed.
Managing and opting out
You have several options for controlling cookies on this site:
- Browser settings. Every modern browser lets you block third-party cookies, delete existing cookies, or block cookies for specific sites. Browser help pages document the exact steps.
- Google Analytics opt-out. Install the official Google Analytics opt-out browser add-on to prevent your activity from being captured.
- Personalized advertising opt-out. Visit Google Ads Settings to manage personalization. Use YourOnlineChoices (EU) or aboutads.info (US) to opt out across many ad networks.
- Do Not Track and GPC. The Global Privacy Control signal sent by some browsers is honored where it is interpreted as an opt-out under applicable law.
Consent
Where the law in your region requires explicit consent for non-essential cookies (notably the EEA, the UK, Switzerland, and several other jurisdictions), the site collects that consent through a prompt the first time you visit. Until you give consent, advertising cookies and personalization signals are not set. You can withdraw consent at any time using the controls described above.
