Privacy Policy

Last Updated: January 2026

Overview

CardioConversion ("we", "our", or "the app") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.

Information We Collect

Analytics Data

We use PostHog, a privacy-focused analytics service, to collect anonymized usage data. This includes:

App opens and session duration
Features used (e.g., equipment conversions, theme changes)
Device type and operating system version
Crash reports and error logs

This data is collected using anonymous identifiers and does not include any personally identifiable information (PII) such as your name, email address, or precise location.

Purchase Information

If you make a purchase within the app, the transaction is processed entirely by Apple (App Store) or Google (Play Store). We do not collect, store, or have access to your payment information, credit card details, or billing address.

We only receive confirmation that a purchase was completed, which allows us to unlock premium features on your device.

Local Data

Your preferences (such as theme settings and custom conversion ratios) are stored locally on your device only. This data is never transmitted to our servers or any third party.

How We Use Your Information

We use the collected analytics data to:

Understand how users interact with the app
Identify and fix bugs or crashes
Improve app features and user experience
Make informed decisions about future development

Third-Party Services

PostHog Analytics

We use PostHog for analytics. PostHog is designed with privacy in mind and allows us to collect usage data without tracking individual users. For more information, visit PostHog's Privacy Policy.

Google AdMob (Free Users)

For users on the free tier, we display advertisements through Google AdMob. AdMob may collect device identifiers and usage data for ad personalization. You can opt out of personalized ads in your device settings. See Google's Privacy Policy.

Apple App Store / Google Play Store

In-app purchases are processed by Apple or Google. Their respective privacy policies apply to those transactions.

Data Retention

Analytics data is retained for up to 12 months, after which it is automatically deleted. Local data on your device persists until you uninstall the app or manually clear app data.

You have the right to:

Request information about what data we have collected
Request deletion of your data
Opt out of analytics collection (contact us)

Right to Restrict Processing: Request limitation of how we process your data
