At JusTheTool, one of our main priorities is the privacy of our visitors. This Privacy Policy explains what information is collected when you use this site, how it's used, and the choices you have.
We do not require you to create an account or provide personal information to use our calculators and tools. Any dimensions, quantities, or other values you enter into a calculator are processed directly in your browser and are never sent to or stored on our servers.
If you contact us by email, we receive whatever information you choose to include in that message (such as your email address and the content of your note). We use this only to respond to you and do not add it to any marketing list.
This site uses Google Analytics (GA4) to understand how visitors use our calculators and guides, so we can improve them. This script loads automatically when you visit the site and begins collecting standard usage data (pages visited, time on site, general device/browser type, and an IP address that we configure Google to anonymize). You can opt out of Google Analytics tracking across all websites by installing the Google Analytics Opt-out Browser Add-on, or block cookies generally through your browser's settings.
JusTheTool displays ads served by Google AdSense and Adsterra to keep every calculator and guide free to use. Scripts from these networks load automatically when you visit the site and may set cookies to serve ads, which can include personalized ads based on your browsing activity, or non-personalized ads if you have opted out of ad personalization in your account settings with the relevant provider.
Google's advertising infrastructure may also contact related services on our behalf — including doubleclick.net for ad delivery and adtrafficquality.google for invalid-traffic detection.
Adsterra may also load ad formats including popunder, social bar, native banner, and display banner units, served from Adsterra's own domains. You can read more in Adsterra's Privacy Policy.
Google, as a third-party vendor, uses cookies to serve ads on this site. Google's use of advertising cookies enables it and its partners to serve ads 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 third-party vendor use of cookies for personalized advertising generally by visiting www.aboutads.info. For general background on how interest-based advertising works, see Google's advertising and privacy policies at https://policies.google.com/technologies/ads.
This Privacy Policy does not apply to other websites we link to, including the guides and calculators on this site that reference external resources. We recommend reviewing the privacy policy of any third-party site you visit from a link on JusTheTool.
JusTheTool does not knowingly collect personal information from children under 13. Our tools are general-purpose calculators intended for a broad audience including DIYers, contractors, and homeowners, and we do not direct content specifically at children.
You can use every calculator and guide on this site fully regardless of your cookie settings — blocking cookies in your browser does not restrict access to any tool or content. If you'd like to know what data, if any, we hold about a specific interaction (such as an email you sent us), contact us and we'll respond directly.
We may update this Privacy Policy as the site evolves. Material changes (such as adding advertising or a new data collection practice) will update the "Last Updated" date above. We encourage checking back periodically.
