ETOS Privacy Policy

Effective Date: January 1, 2026

Welcome to ETOS, your all-in-one server management tool with seamless support for macOS, iOS, Windows, Linux, and Android. At ETOS, we treat your privacy and data security with the utmost seriousness. This Privacy Policy is designed to articulate our unwavering commitment: ensuring that all your information remains exclusively and absolutely within your control. We believe the core value of a professional management tool lies in security and trust, not data collection.

1. Core Principle: Zero Data Collection

We solemnly promise: We do not collect any personal data or information from you.

The ETOS application is engineered for maximum privacy and high security. All server management activities, configuration details, credentials, and operation logs processed through the ETOS app are strictly stored locally on your device. This data never leaves your device, is never transmitted to us, nor shared with any third-party entities.

• Localized Data Storage: Your server information, connection credentials, usage patterns, and all sensitive data reside solely within your local device's file system.
• No Telemetry or Analytics: We have not integrated any form of analytics tools, user behavior trackers, or telemetry systems. We do not know how you use the application.
• No Log or Debugging Data Collection: Even in the event of an application error or a debugging scenario, no diagnostic information is automatically collected or sent to us. Any potential log data generation is restricted to your local device and requires your active and manual action to export and provide to us.
• IP Address Protection: Your IP address, geographical location, or any network identifiers are not within our scope of collection.

2. Information Security and User Control

We are committed to ensuring the absolute security of your information on your local device. While the data remains local, we employ robust security measures within the application (e.g., local data encryption mechanisms, depending on operating system capabilities) to protect against unauthorized access within your local environment.

You have complete control: You can delete the application at any time, and all associated data will be removed simultaneously, without any intervention required from us.

3. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be focused on strengthening privacy protections or enhancing transparency. We will notify you of any material changes by posting the new Privacy Policy within the application interface.
