Privacy Policy
How CalcyTools handles information when you use the site — cookies, advertising, analytics, and your privacy choices.
This Privacy Policy describes how CalcyTools ("we", "us", or "the site") collects, uses and protects information when you visit calcytools.com. We have written it in plain language so it is actually readable, not the templated legalese most sites use.
By using this website you agree to the practices described below. If you do not agree, please do not use the site.
1. About this policy
CalcyTools is a free, advertising-supported website offering construction and home-improvement calculators along with related guides and articles. The site does not require account creation, login, or payment to use any tool or read any content.
This policy covers all pages under the calcytools.com domain. It does not cover the websites of third parties we link to from our content — each of those has its own privacy policy you should review separately.
2. Information you provide
We do not require you to provide any personal information to use the calculators or read the blog. There are no user accounts, no sign-up forms, no paywalled content.
The only times you actively share information with us are:
- When you email us at calcytools@gmail.com — in which case we receive whatever information you choose to include in your message, along with your email address.
- When you submit a calculator request, correction, or feedback via email — same as above.
We do not sell, trade or share email correspondence with third parties. We keep emails as long as needed to maintain useful context for follow-up questions and corrections.
3. Information collected automatically
Like virtually every modern website, CalcyTools and its service providers automatically collect certain technical information when you visit, including:
- Browser type and version
- Operating system and device type
- IP address (used to determine approximate geographic region, never stored alongside personal identifiers)
- Pages visited, time spent, referring website
- Anonymized usage patterns aggregated across many visitors
This information is used to keep the site running smoothly, understand which calculators and articles are most useful, fix problems, and improve content over time. We do not combine this technical information with personal identifiers.
4. Cookies and similar technologies
CalcyTools uses cookies and similar technologies (web beacons, local storage) for the purposes described below. You can disable cookies in your browser settings; doing so will not prevent the calculators from working, though some features that remember your preferences (such as dark mode) may stop working.
The cookies on this site fall into three categories:
- Functional cookies — remember settings like dark mode and recently used calculators.
- Analytics cookies — help us understand how visitors use the site in aggregate.
- Advertising cookies — set by our advertising partners (see below) to serve relevant ads and measure ad performance.
5. Google AdSense and advertising
CalcyTools uses Google AdSense to display advertisements. Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) 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 to you based on your visits to this site and other sites on the Internet.
You can opt out of personalized advertising in any of these ways:
- Visit Google’s Ads Settings to manage Google’s personalized ads.
- Visit aboutads.info to opt out of personalized advertising from many third-party vendors at once.
- In Europe, visit Your Online Choices.
For full details on how Google uses information from sites that use Google services, see Google’s partner sites policy.
6. Google Analytics
We use Google Analytics to understand site traffic and usage patterns. Google Analytics uses cookies to collect anonymous information about your visit — pages viewed, time spent, referring site, browser type, approximate location. We do not collect personally identifiable information through Google Analytics.
You can opt out of Google Analytics tracking by installing the Google Analytics opt-out browser add-on, or by managing cookie settings in your browser.
7. Hosting and infrastructure
The site is hosted on a third-party content delivery network, which automatically logs basic technical information (IP addresses, request timestamps, browser identifiers) for security and performance purposes. These logs are retained for a short period and used only for site operations — detecting abuse, preventing attacks, and diagnosing performance issues.
8. How we use information
The information collected automatically (technical data, cookies, analytics) is used to:
- Operate, maintain and improve the site
- Understand which content and tools are most useful to visitors
- Fix bugs and security issues
- Serve advertising that supports the free site (via our advertising partners)
- Measure the effectiveness of content and advertising
We do not use this information to build personal profiles, to contact you, or to sell to third parties.
9. Information sharing
We do not sell, rent, trade or otherwise transfer your personal information to third parties for marketing purposes. We share information only in these limited circumstances:
- Service providers (hosting, analytics, advertising) who process information on our behalf under contractual confidentiality and data-protection terms.
- Legal requirements when disclosure is required by valid legal process or to protect rights, safety or property.
- Aggregated, anonymized data that cannot identify any individual visitor.
10. Data security
We take reasonable technical and organizational measures to protect information against unauthorized access, alteration, disclosure or destruction. The site is served over HTTPS, our third-party services are reputable and compliance-certified, and we do not store sensitive personal data ourselves. That said, no method of internet transmission or electronic storage is 100% secure.
11. Children’s privacy
CalcyTools is intended for adults (anyone 13 years of age or older). We do not knowingly collect personal information from children under 13. If you believe we have unintentionally collected such information, please contact us at calcytools@gmail.com and we will delete it promptly.
