Privacy Policy

CalCon is a utility app that combines multiple tools in one place, including scientific calculations, unit conversion, currency conversion, date and finance utilities, and lifestyle calculators such as BMI and BMR.

Examples of built-in tools include:

• Scientific and basic calculator with expression editing and calculation history.
• Unit converter for common physical measurements used in daily life.
• Currency converter with support for major and global currencies.
• Percentage, discount, loan, savings, tax, tip, unit price, GPA, date, world time, and fuel-related calculators.
• Health tools such as BMI, BMR, and cycle-based ovulation support.

CalCon does not require account registration for core usage. We do not collect personal profile details such as full name, personal phone number, or personal identity documents.

To keep the app stable and updated, we may process limited non-personal data such as:

• App diagnostics and crash logs.
• General device and operating system details for compatibility support.
• Anonymous interaction metrics to improve tool usability.

Some CalCon features rely on external data, such as exchange rates for currency conversion and time references for world clock conversion. These requests may involve sending technical request metadata like IP address and device networking headers through standard internet protocols.

We use this data only to deliver requested results and service reliability. We do not use it to build personal advertising profiles.

Numbers and values that you enter into calculators are processed to generate outputs inside the app. When history is enabled, prior calculations may be stored locally on your device to improve your experience.

We do not sell your calculation data or use your numeric inputs for targeted advertising.

We use limited data to:

• Provide calculator and converter outputs correctly.
• Improve feature quality, speed, and reliability.
• Fix bugs and monitor technical issues.
• Deliver important product notices and release updates.

Depending on Android version and enabled features, CalCon may request permissions such as internet access for rate updates, notification permission for important app notices, and local storage access when needed for app functionality.

You can review and manage permissions at any time from your device settings.

We use reasonable technical and organizational safeguards to protect service data. However, no software platform can guarantee complete security in every situation.

We do not sell personal data. In limited scenarios, non-personal technical data may be processed by trusted service providers for analytics, crash diagnostics, or infrastructure operations under confidentiality obligations.

We may revise this policy to reflect feature, legal, or technical changes. Updated versions will be published on this page with a revised effective date.
