Privacy Policy

Last updated: June 6, 2026

1. Information We Collect

WrenchRig is a free online calculator tool suite. We do not collect, store, or transmit any personal information you enter into our calculators. All calculations are performed entirely in your browser - your inputs (tire sizes, fuel costs, engine specs, etc.) never leave your device.

We may automatically collect non-personal information through analytics and advertising services, including:

  • Browser type and version
  • Device type (desktop, mobile, tablet)
  • Operating system
  • Pages visited and time spent
  • Referring URL and search terms
  • Approximate geographic location (country/region level)
  • IP address (anonymized where possible)

2. Cookies & Tracking Technologies

WrenchRig uses cookies and similar technologies for the following purposes:

Essential Cookies

These are minimal cookies required for the site to function properly (e.g., remembering unit preferences). They do not track you across sites.

Google AdSense

We use Google AdSense to display advertisements. Google may use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your browsing patterns. You can opt out of personalized advertising by visiting Google Ads Settings or aboutads.info.

Google Analytics

We may use Google Analytics to understand how visitors use our site. Google Analytics uses cookies to collect anonymous traffic data. This data helps us improve our tools and content. You can opt out using the Google Analytics Opt-out Browser Add-on.

3. Amazon Associates Program

WrenchRig is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.

Product links on our tool pages are affiliate links. When you click an affiliate link and make a purchase, we may earn a small commission at no additional cost to you. Amazon may use cookies to track referrals. Please review Amazon's Privacy Notice for details on how Amazon handles your data.

4. Third-Party Services

We use the following third-party services that may collect information as described in their respective privacy policies:

5. Data Retention

Since we do not collect personal data through our calculators, there is nothing to retain or delete. Analytics and advertising data is managed by the respective third-party services according to their data retention policies.

6. Children's Privacy

WrenchRig is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can remove it.

7. Your Rights

Depending on your location, you may have rights regarding your personal data, including:

  • The right to access, correct, or delete your data
  • The right to opt out of personalized advertising
  • The right to restrict data processing

For California residents: Under the CCPA, you have the right to know what personal information is collected and to request its deletion. Since our calculators collect no personal data, this primarily applies to data collected by third-party advertising and analytics services.
