Privacy Policy & Disclaimers

Privacy Policies

Last updated on May 07, 2026

This Privacy Policy describes the types of information we collect, how we use and disclose it, and how privacy expectations differ between the mobile app, the researcher web portal, and study operations. Asdat LLC, located in Seattle, Washington, USA, delivers these services.

• Mobile app (Android): To provide scheduling, app blocking, usage reports, and study features, the app may collect application usage data (which apps run and for how long), device and technical information (for example device model, OS version, language), and configuration you set (schedules, rules, preferences). For research workflows, data may be transmitted to authorized study infrastructure. The in-app Privacy Policy shown inside the app describes collection, use, sharing, aggregated research use, children’s privacy, and contact details in more detail.
• Researcher web portal: Authorized researchers use our platform to configure studies, view analytics, and manage participants. Researcher account and study data are processed to operate the service. Participant records may include pseudonymous identifiers and, where enrollment requires it, information such as phone numbers stored using encryption for operational purposes (for example matching uploads and push notifications).
• Third-party services: We may use providers such as cloud hosting, push notifications (for example Firebase Cloud Messaging), and advertising or measurement technologies where enabled in the app. Those providers process data under their own terms and policies.
• Permissions required (Android manifest): The app declares permissions including INTERNET; RECEIVE_BOOT_COMPLETED; PACKAGE_USAGE_STATS; FOREGROUND_SERVICE and FOREGROUND_SERVICE_SPECIAL_USE; READ_PHONE_STATE and READ_PHONE_NUMBERS; SYSTEM_ALERT_WINDOW (display over other apps) for lock-screen behavior; VIBRATE; MODIFY_AUDIO_SETTINGS; POST_NOTIFICATIONS; ACCESS_NOTIFICATION_POLICY; REQUEST_IGNORE_BATTERY_OPTIMIZATIONS; QUERY_ALL_PACKAGES; REQUEST_DELETE_PACKAGES; optional fingerprint-related permissions where biometric unlock is used; and device administration where that feature is enabled. Exact prompts depend on your Android version and features you turn on.
• Data protection: We use safeguards designed to protect data in transit and at rest, including TLS for network communication where applicable. No method of transmission or storage is completely secure.

Disclaimers for Researchers

• Apps Scheduler is a data collection tool provided by Asdat LLC for use by individuals, researchers, and organizations.
• Asdat LLC does not design, control, or oversee your research studies. You are solely responsible for ensuring your research complies with all applicable laws and ethical standards.
• While Apps Scheduler may demonstrate good accuracy, Asdat LLC does not guarantee the completeness or reliability of any data collected, and shall not be responsible or liable for any data loss, corruption, or inaccuracy.

Disclaimers for Individuals (Participants)

• Your participation in the study and use of the app is entirely voluntary. You may stop using the app at any time.
• If your study uses enrollment or verification, information you provide (such as a phone number) may be stored in encrypted form on study systems so the research team can operate the study and send notifications. Your usage data is typically tied to a participant or study ID. The research team—and applicable consent documents—explain what is collected and how it links to you.
• The research team you consented to work with is responsible for explaining the study and managing your identifiable information.
