Privacy Policy

Last Updated: July 16, 2026

EsdiSoft ("we", "our", or "company") values the privacy of users who use our website (www.esdisoft.com) and mobile applications ("Letrio", "SilentNod", and others). This Privacy Policy explains how your personal data is collected, used, and protected.

1. Information Collected

We may collect the following types of information when performing our services:

• Personal Information: Information such as name, nickname, or email address provided when you contact us or register an account in our apps (e.g., display name in SilentNod).
• Device and Telemetry Information: Device model, operating system version, unique device identifiers (Android ID, FCM Token), and utility telemetry (such as battery level and charging status in SilentNod) required for core app functionalities.
• Usage Data: Anonymous statistical data such as in-app interactions, game scores, activity logs (e.g., movement/status reports in SilentNod), and usage times.

2. Special Notice: No Location Tracking

For our safety utility applications like SilentNod, we value absolute privacy. These apps do not collect, process, or track your real-time geographic location (GPS coordinates). We only monitor device activity status to ensure safety, without tracking your whereabouts.

3. Use of Information

We use the information we collect for the following purposes:

• To provide and improve our services (including transmitting status reports, pings, and remote siren signals).
• To detect and fix application errors.
• To personalize and enhance the user experience.
• To comply with legal obligations.

4. Third Party Services

We may use third-party services such as Google AdMob, Google Analytics, etc. for ad display or analysis in our games/entertainment applications (like Letrio). These services may collect data within the framework of their own privacy policies to analyze user habits.

Note: Our utility/safety applications (like SilentNod) do not display ads and do not share telemetry data with any third-party advertising SDKs.

5. Data Security

We implement industry-standard security measures to ensure the security of your personal data. However, please note that no data transmission over the internet is 100% secure.

6. Children's Privacy

Our services are not intended for children under the age of 13. We do not knowingly collect personal information from children under 13.
