Cookie Policy
Last updated: 1 June 2026
This page describes the cookies and similar technologies used on calctoolsbase.com. Read this together with our Privacy Policy.
1. What's a cookie?
A cookie is a small text file that a website asks your browser to store on your device. Cookies make it possible for a site to recognise that two requests came from the same browser, which is useful for analytics, advertising, and remembering preferences across pages.
2. Cookies set by calctoolsbase directly
None. We do not set any first-party cookies for our own purposes. We have no user accounts, no saved settings, no shopping cart, nothing that needs to persist between visits — so we don't need our own cookies.
3. Third-party cookies and similar identifiers
Cookies on calctoolsbase pages come from third-party services we load:
Google Analytics 4 (analytics)
| Cookie | Set by | Purpose | Typical lifetime |
|---|---|---|---|
_ga | Google Analytics | Distinguishes unique visitors (anonymised ID) | 2 years |
_ga_FGYPRWQHQ9 | Google Analytics 4 | Maintains session state for the GA4 property | 2 years |
Google AdSense / DoubleClick / ad partners (advertising)
| Cookie | Set by | Purpose | Typical lifetime |
|---|---|---|---|
__gads | Google AdSense | Ad serving and frequency capping | 13 months |
__gpi | Google Ad Manager | Ad personalisation identifier | 13 months |
NID | Personalisation preferences, security | 6 months | |
IDE | doubleclick.net | Ad-impression measurement | 13 months |
| various | AdSense advertising partners | Vary by partner — see Google's ad-tech disclosures | varies |
The exact list of advertising partners changes over time. Google publishes the current set at Google's ad technology providers list.
Google Fonts
Loading fonts.googleapis.com and fonts.gstatic.com does not generally set persistent cookies on your browser; it is a same-origin font fetch.
4. We do not currently load
- Meta Pixel / Facebook Connect / Facebook SDK
- TikTok Pixel
- X (Twitter) advertising pixel
- LinkedIn Insight Tag
- Microsoft Clarity, Hotjar, or any session-replay tool
- Any chat-widget or popup vendor
If this changes, this page will be updated before the change goes live.
5. Managing cookies
You can clear, block, or selectively allow cookies through your browser settings. Most modern browsers also include built-in tracking protection that automatically restricts cross-site cookies — this works without affecting our calculators.
For advertising-specific controls:
- adssettings.google.com — Google's personalised-ad controls
- youradchoices.com (US)
- youronlinechoices.eu (EU / EEA)
6. EEA / UK / Swiss consent
If you are in the EEA, UK, or Switzerland, Google's certified consent management interface will appear on your first visit (or after a clearing) and lets you grant or refuse consent for advertising cookies, personalisation, and similar purposes. The site remains usable whether you accept or decline.
