Privacy Policy - Ruler Application

Effective Date: August 31, 2025

Overview

Ruler is a simple measurement tool application developed by TaoZai. This application is designed to assist users in performing measurements using their device and does not collect, store, or transmit any personal information or user data. This privacy policy explains how we handle data related to this application to ensure compliance with applicable laws and Google Play Store policies.

No Collection of Personal Data

The Ruler application does not collect, store, or transmit any personal or sensitive information about its users. Personal data includes, but is not limited to, names, email addresses, phone numbers, location data, IP addresses, device information, or any other identifiable information.

• No Data Collection: The application operates locally on your device, and all functionalities (such as on-screen measurements) are performed without requiring an internet connection.
• No Third-Party Services: The application does not use any third-party analytics tools, advertising services, or other services that may collect user data (e.g., Google Analytics, Crashlytics, or Flurry).
• No Data Sharing: Since we do not collect any data, no user data is shared with any third parties.

Data Storage and Security

As the Ruler application does not collect any personal data, there is no need to store any data on the device or remote servers. Any local storage is limited to temporary data required for the application’s operation (e.g., measurement settings), which is cleared when the application is closed and is not transmitted to any external servers.

User Permissions

The Ruler application may require access to certain device permissions (e.g., camera for augmented reality measurement features, if applicable). Any such permissions are used solely to provide the core functionality of the application and are not used to collect or store any personal data. We will clearly explain the purpose of any permissions requested.

User Rights

Since the application does not collect any personal data, there is no need for users to request access, modification, or deletion of data. If you have any questions about the privacy practices of this application, please contact us using the information below.

Changes to This Privacy Policy

We may update this privacy policy from time to time to reflect changes in legal requirements or application functionality. Any significant changes will be communicated to users within the application or through our website (if applicable). The latest version of this privacy policy will always be accessible via a link within the application or on the Google Play Store listing.
