This Cookie Policy explains what cookies are, how CalcGrids (“we”, “us”, “our”) uses them on calcgrids.com, and how you can manage your preferences.
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work, improve performance, and provide information to website owners.
Similar technologies such as local storage, session storage, and pixel tags may also be used for equivalent purposes and are covered by this policy.
CalcGrids uses three categories of cookies:
| Category | Purpose | Examples | Consent Required |
|---|---|---|---|
| Essential | Required for the website to function. Includes session management, security, and basic site operation. | Session cookies, security tokens, consent record | Not required |
| Analytics | Help us understand how visitors use CalcGrids — which calculators are used, session duration, and how to improve the site. | Google Analytics (_ga, _gid, _gat) | Required (GDPR/ePrivacy) |
| Advertising | Used to display relevant advertisements via Google AdSense. May be used to personalise ads based on interests and browsing history. | Google AdSense (IDE, DSID, test_cookie) | Required (GDPR/ePrivacy) |
Essential cookies are strictly necessary for the website to function and cannot be disabled. They do not collect personal information for marketing purposes. These include:
With your consent, CalcGrids uses Google Analytics to understand how visitors use the site. Google Analytics may set cookies such as _ga, _gid, and _gat to distinguish users and throttle request rates.
Analytics cookies are only activated after you provide consent. You can withdraw consent at any time using the Manage Cookie Preferences control in the website footer.
With your consent, CalcGrids displays advertisements through Google AdSense. Google AdSense may set cookies such as IDE and DSID to serve personalised advertisements based on your interests and previous browsing activity.
Advertising cookies are only activated after you provide consent. If you decline advertising cookies, ads may still appear but will not be personalised.
For more information about how Google uses data from advertising cookies, visit Google's advertising policies.
You can manage or withdraw your cookie consent at any time using the following methods:
Your consent choice is stored locally on your device in localStorage under the key cg_cookie_consent_v2. This record expires after 365 days, after which you will be asked to provide consent again.
No consent data is transmitted to CalcGrids servers. Your choice is stored and read entirely on your own device.
We may update this Cookie Policy from time to time. Any updated version will be posted on this page with a revised effective date.
