Privacy Policy — Cholesterol Tracker

Last updated: July 10, 2026

Cholesterol Tracker ("the App") is operated by Vladimir Lukashov ("we", "us"). This policy explains how the App handles your information. The short version: your health data stays on your device.

Your health data stays on your device

• The App works on your device and offline. It has no accounts and no login.
• The lipid values you enter (cholesterol, LDL, HDL, triglycerides), test dates, and the sex setting are stored locally on your device only. We do not collect, see, or transmit them. There is no server.
• The App does not connect to Apple Health (HealthKit).
• We do not collect your name, email, location, or any personal or usage data.
• We do not use advertising or tracking of any kind.
• Deleting the App deletes all your entries.

Purchases

The App offers an auto-renewing subscription. Payment is processed by Apple through the App Store; we never see your payment details. To validate purchases the App uses RevenueCat, which receives an anonymous purchase receipt and a random identifier — never your identity and never your health entries. See RevenueCat's privacy policy.

Children

The App is not directed at children under 13 and we do not knowingly collect data from them.

Changes

If this policy changes, the updated version will be posted at this address with a new date.
