Privacy Policy
Your privacy matters. Here's exactly how we handle your data.
Last updated: December 2025
Your Calculator Data is 100% Private
Calcmatic does NOT collect, store, or sell any information you input into our calculators.
All calculations happen entirely in your browser. Your financial data never touches our servers. We cannot see your mortgage amounts, investment figures, tax numbers, or any other data you enter. Period.
- • Calculator inputs: Your mortgage amounts, salaries, investment figures, tax data, or any numbers you enter
- • Personal information: Your name, email, phone number, or address
- • Financial accounts: We never ask for or access your bank, investment, or credit accounts
- • Calculation results: Your computed results stay in your browser and are never sent anywhere
To keep Calcmatic free for everyone, we display advertisements from trusted advertising networks. Here's what you should know:
Google AdSense
We use Google AdSense to display relevant advertisements. Google may use cookies to serve ads based on your prior visits to this site or other websites.
You can opt out of personalized advertising by visiting Google's Ads Settings .
Ezoic
We partner with Ezoic for ad optimization and delivery. Ezoic uses AI technology to test and optimize ad placements for the best user experience and revenue.
Ezoic may use cookies for ad targeting, frequency capping, and performance measurement.
For complete details about Ezoic's data practices and cookies used on this site, please see the Ezoic Privacy Disclosures for Calcmatic .
We use analytics tools to understand how visitors use our site, which helps us improve our calculators and user experience. These tools collect anonymous, aggregated data.
Google Analytics 4
We use Google Analytics 4 (GA4) to collect anonymous usage data including pages visited, time on site, and general geographic location (country/city level). This data helps us understand which calculators are most useful and how we can improve.
GA4 uses cookies to distinguish unique users and sessions. No personally identifiable information is collected.
You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on .
Microsoft Clarity
We use Microsoft Clarity to understand how users interact with our calculators through heatmaps and session recordings. This helps us identify usability issues and improve the calculator experience.
Clarity masks all sensitive input fields by default, meaning your calculator inputs (numbers, financial data) are never captured in recordings. Clarity does not collect personally identifiable information.
