This Privacy Policy describes how LensDays Tracker (“the App”) handles user data.

Data Collection

The App collects limited, non-personal data to improve functionality and understand how the App is used.

This data may include:

• app usage events
• subscription and purchase status
• anonymous device and app information (such as app version or system version)

The App does not collect personally identifiable information, such as name, email address, phone number, or precise location.

Data Storage

All user-entered data (such as lens usage periods and preferences) is stored locally on the user’s device and is not stored on the developer’s servers.

Third-Party Services

The App uses the following third-party services:

• RevenueCat — to manage subscriptions and in-app purchases
• Amplitude — to collect anonymous analytics and usage statistics

These services may process anonymous data in accordance with their own privacy policies.

Data Sharing

The App does not sell personal data and does not share personally identifiable information with third parties.

User Rights

Since the App does not collect personally identifiable information, users cannot be individually identified.
