Privacy Policy

Mortgage calculations on Mortgage Number Lab run in your browser on your device. Financial values you enter — such as home price, loan amount, interest rate, income, or debt payments — are processed locally as you use each tool.

These input values are not transmitted to our servers, not stored in a database, and not shared with third parties by our application.

When you use the share feature on a calculator, your inputs may be included in the page address (URL) so you can bookmark or send a link. We do not store those values — they exist only in the link you choose to share.

Like most websites, our hosting infrastructure may automatically record certain technical information when you visit, which can include:

• Your IP address (used for server-side request handling)
• Browser type and version
• Operating system and device type
• Pages visited and time of visit
• Referring website (the page that linked you here)
• General geographic region derived from IP address

This information is used for technical operation, security, and aggregate traffic analysis. We do not use this information to identify individuals.

We may use Google Analytics to understand how visitors use Mortgage Number Lab — for example, which pages are viewed and whether calculators or guides are opened. Analytics may collect usage and technical information such as browser type, device type, and general engagement with the site.

Financial values you enter into calculators — such as home price, loan amount, interest rate, or income — are not sent to Google Analytics. Analytics does not receive your mortgage inputs as part of its reports.

Google Analytics data is processed according to Google's Privacy Policy. You can learn more about Google Analytics and opt out of certain data collection through Google's Analytics opt-out browser add-on.

Mortgage Number Lab may display advertisements provided by Google AdSense and other advertising partners.

Third-party vendors, including Google, may use cookies, web beacons, IP addresses, device identifiers, or similar technologies to serve and measure advertisements on this website. Where permitted by your settings, applicable law, and region, these technologies may also be used to personalize ads based on visits to this website and other websites.

These technologies may be used to:

• Serve and personalize advertisements where permitted
• Measure advertising performance and reach
• Limit repeated advertisements
• Detect and prevent advertising fraud
• Comply with applicable legal and regulatory requirements

You can manage personalized advertising preferences through Google's Ad Settings. Google may process information collected through this website in accordance with its privacy policies and advertising policies.

Advertisements are displayed separately from calculator tools and educational content. Advertisers do not influence calculator formulas, results, or editorial content on this site.

Mortgage Number Lab does not set cookies for calculator functionality or to remember your mortgage inputs.

Third-party services that may set cookies or use similar technologies include:

• Google Analytics — to measure aggregate site usage and performance
• Google AdSense and advertising partners — to serve and measure ads, and where permitted, to personalize advertising

Each third-party service is governed by its own privacy and cookie policies. You can manage cookies through your browser settings. Depending on your location, personalized advertising may be subject to additional consent requirements under local law.

This website may use third-party services for hosting, analytics, and advertising. Each third-party service has its own privacy practices and is not covered by this policy. We encourage you to review the privacy policies of any third-party service whose content or functionality appears on this site.

Mortgage Number Lab may contain links to external websites. We are not responsible for the privacy practices, content, or accuracy of any external website. Clicking an external link means leaving our site, and this privacy policy no longer applies.

We use reasonable technical measures to protect the website and its infrastructure. Because calculator values are not transmitted to our servers, the primary data security consideration is your browser and device security.

No internet transmission or storage system is completely secure. We do not warrant that information will never be accessed, disclosed, altered, or destroyed if a system breach occurs.

Mortgage Number Lab is designed for general adult audiences seeking residential mortgage information. It is not directed toward children and is not intended for use by minors. We do not knowingly collect personal information from children.

We may update this privacy policy from time to time to reflect changes in our practices, technologies, legal requirements, or other factors. When we make material changes, we will update the "Last updated" date shown at the bottom of this page.

Continued use of Mortgage Number Lab after an update constitutes acceptance of the revised policy.
