Overview
Calsify ("we", "us", or "our") operates the website calsify.net. This Privacy Policy explains how we collect, use and protect information when you use our website. We are committed to protecting your privacy and handling your information responsibly.
By using Calsify, you agree to the collection and use of information in accordance with this policy.
Calculator Data — We Don't Collect It
All calculations performed on Calsify are processed entirely within your web browser using JavaScript. The values you enter into any calculator — loan amounts, income figures, health measurements, dates, or any other personal data — are never transmitted to our servers and are never stored in any database or log. This is not just a policy; it is a technical fact about how our calculators work.
When you close the browser tab or navigate away from a calculator page, your inputs are gone. We have no record of them.
Information We Do Collect
Log Data
Like most websites, our web server automatically records standard log data when you visit our site. This may include your IP address (anonymized), browser type, browser version, the pages you visit, the time and date of your visit, and time spent on each page. This information is used solely for security monitoring and aggregate traffic analysis. It is not linked to any personally identifiable information.
Cookies
Calsify uses a minimal set of cookies necessary for the website to function correctly. We do not use first-party tracking cookies. Third-party services we use (see below) may set their own cookies as described in their respective privacy policies.
Third-Party Services
Analytics
We may use web analytics services to understand how visitors use our site in aggregate. Any such service collects information anonymously and reports website trends without identifying individual visitors. Aggregated data helps us improve site performance and content quality.
Advertising
Calsify may display advertisements to support free access to all tools. Any advertising network we use may employ cookies to serve relevant ads. You can typically opt out of interest-based advertising through your browser settings or your ad network's opt-out page. We will update this section with specific details when advertising services are activated on this site.
Fonts
Calsify uses Google Fonts to load typefaces. When you visit our site, your browser may make a request to Google's servers to retrieve font files. This is governed by Google's Privacy Policy.
Content Accuracy and Review Standards
Calsify publishes calculator pages with formula explanations, worked examples, and FAQ guidance. We review core formulas and update content when assumptions or rules materially change. If you report a potential error, we investigate and correct confirmed issues as quickly as possible.
Our calculators are educational tools and estimate outcomes based on the inputs provided. For final decision-making, always verify results with official sources and qualified professionals relevant to your case.
Data Security
We take reasonable measures to protect the information on our servers. Our website uses HTTPS encryption for all communications. However, no method of transmission over the internet is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee its absolute security.
Children's Privacy
Calsify does not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will delete it promptly.
Links to Other Websites
Our website may contain links to external websites. We have no control over the content and privacy practices of those sites and are not responsible for their privacy policies. We encourage you to review the privacy policy of any external site you visit.
Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
