Privacy Policy — Your Data Stays in Your Browser

Privacy Policy

Your data stays
on your device. Period.

Last updated: 2026-08-01  ·  Version 1.0

🔒 No calculator inputs are ever transmitted

Short version — plain English

• What you type into a calculator never leaves your browser
• We use Google Analytics to count visitors — without your input values
• We use Google Blogger for hosting — standard Google cookies apply
• We don't sell data. We don't have any to sell.

1. What we never collect

The following data never leaves your device under any circumstances:

💰 Loan & mortgage amounts

📊 Income & tax figures

🎂 Dates of birth

🔢 Any calculation result

2. What is collected automatically

Our hosting provider (Google Blogger) and analytics tool (Google Analytics 4) collect standard usage data:

• IP address (anonymised by Google Analytics)
• Browser type, version, and operating system
• Pages visited and approximate time spent
• Referring URL (which site linked you here)

This data is used only to understand aggregate traffic patterns and fix usability problems. It is never sold.

3. Google Analytics

We use GA4 to track general events: page views, whether a calculator was completed, and whether the result was copied. We do not pass calculator input values as event parameters. If our privacy policy says your data stays in the browser, we enforce that in the analytics code too — not just the disclaimer.

You can opt out using the Google Analytics opt-out browser add-on.

4. Cookies

Google Analytics sets session cookies. Google Blogger may set functional cookies. Reckonly itself does not set advertising or tracking cookies.

5. Shareable links

The Mortgage and Loan calculators support shareable links by encoding your inputs in the URL (e.g. ?p=300000&r=6.5). These values appear in your browser history. This feature is disabled for the Income Tax and Age calculators where inputs are more personal.

6. Local storage

We may use localStorage to remember UI preferences such as your chosen currency symbol. No financial inputs or personal data are stored this way.
