Privacy Policy
Last updated: July 19, 2026
This policy describes how CalculatorUSA App (calculatorusaapp.com) handles information when you use our educational calculators and guides. We aim to keep data collection minimal.
1. Who we are
CalculatorUSA App is an independent educational website that publishes free US personal-finance and everyday-math calculators. Contact: contact@calculatorusaapp.com · Contact page.
2. Calculator inputs (browser-side)
Calculator math runs in your browser from values you type. We do not require an account and we do not ask for Social Security numbers, full bank account numbers, passwords, or government ID numbers to use the tools.
- Do not paste sensitive identifiers into calculators or into screenshots you share publicly.
- If a future feature ever stores inputs on a server, we will update this policy before enabling it.
3. Information we may receive automatically
Like most websites, our hosting provider and any analytics we enable may process standard technical data, for example:
- IP address, approximate location derived from IP, browser type, device type, and operating system
- Pages visited, referring URL, timestamps, and diagnostic logs needed to operate and secure the site
4. Cookies and similar technologies
We may use cookies, local storage, or similar technologies for essential site operation, preference storage, analytics, and — when advertising is enabled — ad delivery and measurement.
- Essential: security, load balancing, basic preferences.
- Analytics (if enabled): aggregate traffic and product improvement (e.g. Google Analytics or similar).
- Advertising (if enabled): cookies used by Google and authorized partners to show and measure ads.
You can control cookies through your browser settings. Blocking some cookies may affect site features.
5. Advertising (Google AdSense and partners)
If we participate in Google AdSense or similar ad networks, third parties — including Google — may use cookies or similar technologies to serve ads based on your prior visits to this site or other sites, and to measure ad performance.
- Google’s use of advertising cookies is described in Google’s Advertising policies and Google Privacy Policy.
- Users can opt out of personalized advertising via Google Ads Settings and industry tools such as aboutads.info.
- We do not sell your calculator inputs as a product dataset.
6. Analytics
If analytics tools are enabled, they help us understand which calculators are used and how the site performs. Analytics providers process data under their own privacy policies. We configure tools to support legitimate operation of an educational publisher site.
7. External links
We link to official resources (for example IRS, CFPB, HUD, SSA). Those sites have their own privacy practices. We are not responsible for third-party content or policies.
8. Children
The site is intended for a general audience interested in personal-finance education. We do not knowingly collect personal information from children under 13. If you believe a child provided personal information, contact us and we will delete it where applicable.
9. Data retention and security
Server logs and analytics data are retained only as long as needed for security, debugging, and aggregate reporting, subject to provider defaults. No method of transmission over the Internet is perfectly secure; we use HTTPS and standard hosting protections.
10. Your choices and requests
Depending on your location, you may have rights to request access, correction, or deletion of personal information we hold about you (for example, email correspondence). Contact contact@calculatorusaapp.com. We may need to verify the request and retain limited records where required by law or fraud prevention.
11. Changes to this policy
We may update this page when our practices or products change. The “Last updated” date at the top will change when we do. Continued use of the site after updates means you accept the revised policy.
