How Big Calculator Works

Big Calculator is a fully offline application that operates entirely on your device:

• ✅ Your calculation history is stored only on your device
• ✅ Currency conversion rates are pre-loaded and work offline
• ✅ Settings and themes are saved locally to your device
• ✅ No internet connection is ever required or used

Third-Party Services

None. Big Calculator does not integrate with any third-party services, analytics tools, advertising networks, or cloud services. Your data never leaves your device.

Data Storage

Any data (calculation history, settings, theme preferences) is stored locally on your device using Apple's standard storage systems. This data:

• Remains entirely under your control
• Is deleted when you uninstall the app
• Can be cleared at any time from within the app
• Is never backed up to any external servers

Children's Privacy

Big Calculator is safe for users of all ages. Since we don't collect any data, children can use the app without any privacy concerns. The app complies with COPPA (Children's Online Privacy Protection Act) by not collecting any information from anyone.

Accessibility Features

Our accessibility features (large text, high contrast themes, haptic feedback) work entirely on your device without any data collection or external processing.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected in the app and on this page with an updated "Effective Date." However, our core commitment to not collecting any user data will never change.

Your Rights

Since we don't collect any data, there's nothing to request, correct, or delete. You have complete control over any locally stored data through the app itself.

Frequently Asked Questions

Why is Big Calculator free?

We believe everyone deserves access to accessible tools. Big Calculator is our contribution to making technology more inclusive for people with vision difficulties or anyone who prefers large, clear displays.

Do you really collect zero data?

Yes, absolutely zero. We don't even know you're using the app. There are no analytics, no crash reporting, no usage statistics - nothing. The app works 100% offline on your device.

What about the currency converter?

Exchange rates are pre-loaded in the app and work offline. While rates may not be real-time, this ensures your privacy is never compromised for a feature.

Will you ever add ads or paid features?

No. Big Calculator will always be free, ad-free, and without any paid features or subscriptions.

How do you sustain the app without revenue?

Big Calculator is part of our Big Apps suite of accessibility-focused applications. It's our way of giving back to the community.
