Cookie Policy
Last updated: July 28, 2026
Overview
This Cookie Policy explains how VehCalc uses cookies and similar technologies to operate our website and improve your experience. Cookies are small text files stored in your browser that help websites recognize you on future visits, remember your preferences, and understand how our site is being used.
At VehCalc, we take a minimal approach to cookies. We only use them when necessary to provide our service, and we never use them to track you across other websites or to build advertising profiles.
Essential Cookies
These cookies are strictly necessary for the basic operation of our website. Without them, the site would not function properly.
| Cookie Name | Purpose | Duration |
|---|---|---|
| session_id | Maintains session state during your visit | Session |
| unit_preference | Saves your unit selection (imperial/metric) | 1 year |
| calculator_theme | Remembers your display preferences | 1 year |
Analytics Cookies
We use Google Analytics to understand how visitors interact with our website. This helps us improve our calculators, fix technical issues, and create better user experiences. Analytics cookies collect anonymous information only — we cannot identify individual users from this data.
| Cookie Name | Purpose | Duration |
|---|---|---|
| _ga | Google Analytics - distinguishes users | 2 years |
| _ga_* | Google Analytics - preserves session state | 2 years |
| _gid | Google Analytics - distinguishes users daily | 24 hours |
Advertising Cookies
We use Google AdSense to display advertisements on our website. AdSense may set cookies to deliver more relevant ads and limit the number of times you see the same ad. These cookies do not identify you personally and are not used to track you across unrelated websites.
How AdSense is loaded. The AdSense library is requested by the page on load, and Google Consent Mode is set to "denied" for ad storage, ad user data and ad personalization before that request is made. While consent is denied, Google does not read or write advertising cookies on your device and does not build an advertising profile from this site; if you accept, the signals are upgraded and ads may be personalized. If you decline, they stay denied. We also honour the Global Privacy Control signal as an automatic opt-out.
You can control ad personalization through your Google Account settings or by adjusting your browser's cookie preferences.
Managing Your Cookie Preferences
Most web browsers allow you to control cookies through their settings. You can:
- Block all cookies: Configure your browser to reject all cookies. However, this may prevent essential features from working properly.
- Block third-party cookies: You can allow only first-party cookies while blocking cookies from external services like Google Analytics and AdSense.
- Delete existing cookies: Clear cookies from your browser at any time. This will reset any preferences you may have set.
- Set exceptions: Allow cookies from specific websites while blocking others.
Please note that blocking cookies may affect your experience on VehCalc. Essential cookies are necessary for core functionality, while disabling analytics cookies simply means we won't be able to improve the site based on usage data.
Cookie Consent
Depending on your jurisdiction, you may have specific rights regarding cookie usage. VehCalc is committed to complying with applicable regulations, including the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
VehCalc displays a consent banner to first-time visitors that lets you Accept or Reject non-essential cookies — both analytics and, when advertising is enabled, advertising cookies — before any of them are set. Until you make a choice, Google Analytics runs in cookieless mode: no cookies or identifiers are written to your device and only aggregated, modelled measurements are collected. The same rule covers advertising: the AdSense library may be requested on page load, but with Consent Mode set to "denied" no advertising cookie is written and no advertising profile is built until you accept. Your choice is stored locally on your device, and you can change it at any time by clearing your browser cookies or using the controls described above. For visitors in the EEA or the United Kingdom, we request explicit consent before any non-essential cookie is used. If your browser sends a Global Privacy Control (GPC) signal, we treat it as a rejection and no non-essential cookies are set at all. If you have questions about cookie consent or your privacy rights, please refer to our Privacy Policy or reach out through our contact page.
Changes to This Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in our cookie practices or for legal, operational, or regulatory reasons. When we make material changes, we will update the “Last updated” date on this page.
