Privacy policy
Quick answer
This site collects no account data because it has no accounts. It uses Google Analytics for aggregate traffic measurement, and following an affiliate link passes a referral identifier to the retailer. Email addresses are collected only when you submit a form yourself.
What this site collects
CheckEngineCalc has no accounts, no logins and no user profiles, so there is no personal data held about you as a visitor by default. The exceptions are listed below.
Analytics
The site uses Google Analytics to understand aggregate traffic: which pages are read, roughly where visitors come from and which links are followed. This uses cookies and collects a truncated IP address. It is used to decide what to write next, not to identify individuals. Google's own privacy policy governs what it does with that data, and browser level controls or an ad blocker will prevent the collection entirely.
Affiliate links
Links to retailers carry a referral identifier so that commission on a resulting purchase is attributed correctly. Following one takes you to that retailer, where their privacy policy and their cookies apply. This site does not transmit any personal information about you to a retailer.
Forms
If you submit the contact form or request a printable list, the email address and any message you type are delivered to the site owner by a third party form delivery service. That address is used to reply to you or to send what you asked for, and it is not sold or passed to advertisers. If you would like it deleted, ask through the contact page.
Hosting
The site is served as static files from a content delivery network, which keeps standard server logs including IP addresses for security and abuse prevention. Those logs are not used by this site for analytics or profiling.
Changes
If this policy changes materially, the change will appear on this page. Continuing to use the site after a change indicates acceptance of it.
Common questions
Do you sell personal data?
No. There is nothing to sell: the site has no accounts, no logins and no user profiles. The only personal data it ever holds is an email address you typed into a form yourself, and that is used to reply to you or to send the list you asked for.
What does following an affiliate link share?
A referral identifier that tells the retailer the visit came from this site, which is how commission is attributed. The retailer then applies its own privacy policy and its own cookies, which are outside this site’s control. No personal information about you is transmitted by this site at that point.
