Privacy Policy
Plain-English summary: the calculators run entirely in your browser, we don't ask you to log in, and we don't sell your data. The detail below covers analytics, advertising, and affiliate links.
Who we are
benchcalcs.com ("BenchCalcs", "we", "us") is a network of free interactive calculators operated by Andromeda Kinship. Contact: [email protected].
What the calculators collect
Nothing we can see. Every calculator runs entirely in your browser. The numbers you type — room dimensions, zip codes, tank volumes, and so on — are processed locally on your device and are never transmitted to a server or stored by us. So the calculator can remember your inputs on your next visit, they are saved only in your own browser's local storage; clearing your browser data removes them. There is no email signup anywhere on the site — we never collect email addresses.
Analytics
We currently run no analytics of our own — no tracking scripts, no cookies, no fingerprinting from us. If we enable a privacy-preserving, cookieless tool such as Cloudflare Web Analytics to understand aggregate traffic, this page will be updated to say so.
Advertising
Pages on this site display ads served by Google AdSense. 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 based on your visit to this site and/or other sites on the Internet. You may opt out of personalized advertising at Google Ad Settings, and opt out of many other vendors at optout.aboutads.info (US) or youronlinechoices.eu (EU).
- Google uses advertising cookies as described in Google's advertising policies. You can opt out of personalized Google ads at Google Ad Settings.
- You can opt out of personalized advertising from many vendors at optout.aboutads.info (US) or youronlinechoices.eu (EU).
We may also work with other ad-management platforms such as Ezoic in the future; this page will be updated if that happens.
Affiliate links
Some links to products and services are affiliate links — including the Amazon Associates program and others described on our affiliate disclosure page. When you click an affiliate link, the destination vendor may set a cookie to attribute a later purchase to this site. We earn a commission on qualifying purchases at no additional cost to you. We do not receive your payment details or personal information from these purchases — only aggregate commission reports from the vendor.
As an Amazon Associate, we earn from qualifying purchases.
Your rights (GDPR / CCPA)
Because the calculators collect no personal data, there is normally nothing for us to access, correct, or delete. For data handled by our advertising and analytics partners, use the opt-out links above, or contact us and we will direct your request to the appropriate partner. California residents may exercise rights under the CCPA, and EU/UK residents under the GDPR, by emailing [email protected].
Children
This site is not directed at children under 13 and we do not knowingly collect personal information from them.
Changes
We may update this policy as the site's advertising or analytics setup changes. The "last updated" date at the top reflects the most recent revision.
