Privacy Policy
McGonster Monster Motors LLC ("MMM," "we," "us") operates mcgonster.com and the connected tool network (including twincamdyno.com, predator212dyno.com, 351clevelanddyno.com, sbc350dyno.com, m8dyno.com, 454dyno.com, and related domains). This policy explains what information we collect, how we use it, and the choices you have.
Information We Collect
The calculators and dyno tools on this site run entirely in your browser. The engine, part, and jetting selections you make are not tied to your identity and are not stored on our servers.
If you contact us directly (for example, by email or through the contact form), we collect whatever information you choose to include, such as your name, email address, and message.
Analytics
We use privacy-focused web analytics (such as Cloudflare Web Analytics) to understand aggregate traffic — pages visited, general location, device type. Our analytics does not use tracking cookies or build a profile of individual visitors. Cookies used for advertising are described in the Advertising section below.
Advertising
We use Google AdSense to display advertising on this site and on tool sites in the MMM network. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info/choices. For more information about how Google uses data when you use our partners' sites, see How Google uses information from sites or apps that use our services.
Visitors in the European Economic Area, the United Kingdom, and Switzerland are shown a consent message and can choose whether to allow cookies for personalized advertising.
Affiliate Links
Some links on this site are or may become affiliate links through retailer affiliate programs (such as those operated by eBay, Amazon, Summit Racing, JEGS, and J&P Cycles). When you click one of these links and make a purchase, we may earn a commission at no additional cost to you. Clicking an affiliate link may set a cookie or tracking parameter on the retailer's site so that the purchase can be attributed to us — this is handled by the retailer (eBay, Amazon, etc.), not by MMM directly. See our Terms of Service for more on how these tools and links are provided.
Newsletter & Email Signup
If you choose to enter your email address in the optional newsletter signup (for example on a printable dyno sheet from one of our tools), we use it only to send you McGonster Monster Motors updates — new tools, build guides, and site news. Signups are delivered to our inbox by FormSubmit (formsubmit.co), which processes the form submission on our behalf. We do not sell or share your email address with anyone, and you can unsubscribe at any time by replying to any newsletter email or writing to mcgonster@gmail.com. Printing a dyno sheet never requires an email address — the signup is entirely optional.
How We Use Information
- To operate, maintain, and improve the tools on this site.
- To respond to messages sent to us directly.
- To understand aggregate site traffic and usage patterns.
We do not sell personal information, and we do not share it with third parties except as required to operate the site (such as our hosting, analytics, and advertising providers described above) or as required by law.
Children's Privacy
This site is not directed at children under 13, and we do not knowingly collect personal information from children.
Changes to This Policy
We may update this policy from time to time. Changes will be posted on this page with an updated "last updated" date.
