Privacy Policy for Yazan Teknoloji Apps (SessizCami, SilentSchool & SilentHospital)

Last updated: May 11, 2026

This Privacy Policy describes how SessizCami (Masjid Peace), SessizOkul (SilentSchool), and SilentHospital, developed by Yazan Teknoloji, collect, use, and protect user information. Our primary goal is to provide distraction-free environments—whether in a place of worship, an educational institution, or a healthcare facility—while maintaining the highest level of user privacy.

1. Information We Collect and Its Purpose

We are committed to the principle of data minimization. Our apps collect only what is strictly necessary to function.

a. Location Information (CRITICAL FOR CORE FUNCTIONALITY)

To provide automated silent mode features, the Apps must know when you enter or exit a designated zone (Mosque, School, or Hospital).

Foreground & Background Location: The Apps require access to your location even when they are closed or running in the background. Without this, the Apps cannot detect your entry into a silent zone while your phone is in your pocket.

Real-time Processing: Location data is processed locally on your device in real-time.

Privacy First: We DO NOT store, save, or transmit your location data to our servers. Your movements are never tracked or logged.

b. Device and Usage Information

We collect limited technical data (Device model, OS version, and crash logs) via Google Firebase to improve app stability and performance for our diverse global user base.

2. Specialized Modes & Permissions

🕌 Imam & Muezzin Mode (SessizCami): Uses precise geofencing to distinguish between prayer halls and residential areas.

🎓 Educator & Professional Mode (SilentSchool): Optimized for schools and offices to ensure automation aligns with professional schedules.

🏥 Healthcare & Patient Mode (SilentHospital): Specifically designed for hospital environments to ensure a quiet atmosphere for patients and medical staff.

Logic: All specialized logic is processed entirely on-device.

3. Essential Permissions

Location Permission: To detect proximity to mosques, schools, or hospitals.

Background Location: To automate silence even when the screen is off.

Do Not Disturb (DND) Access: To physically toggle the silent/vibrate mode on your device.

4. Advertising & Monetization

Google AdMob: Our apps are supported by Google AdMob. AdMob may use device identifiers to show personalized or non-personalized ads to sustain the service. You can manage these settings in your device’s Google settings.

In-App Support (Donations/Coffee): Optional in-app purchases are available to support development. These transactions are handled securely by Google Play Billing. We do not collect or store your financial information.

5. Data Sharing and Retention

No Sale of Data: We do not sell, rent, or trade user data.

Third-Party Services: We use Firebase (Analytics/Crashlytics) and AdMob. These services process data under their own privacy policies.

Zero Retention Policy: Since we do not maintain a central user database, we do not retain any personal information or location history.

6. Your Rights and Control

You have full control over your privacy:

You can revoke location permissions at any time through device settings (this will disable the core automation feature).

You can stop all data collection by uninstalling the Apps.
