Privacy Policy

Overview

This page describes how szajsjem.cc, WebRelay, Music Player, and Magnetic Mapper handle data.

Questions about privacy or deletion can be sent to [email protected].

Website and WebRelay

szajsjem.cc and WebRelay may process operational data needed to run and secure the service. This can include IP addresses, timestamps, session or room identifiers, device identifiers, message sizes, and similar connection metadata.

If you want an IP address removed from logs or other WebRelay-related data, send a deletion request to [email protected].

Music Player

Music Player is an offline-first Android app and does not use an account system.

With user permission, it reads local audio files and metadata to build a music library. Data stored locally can include playlists, playback history, favorites, skips, ratings, listening statistics, profiles, settings, and recommendation data such as short-term and long-term taste vectors.

Optional network features include paired-device sync, presence, and group sessions. When those features are used, relay connection metadata may be processed by WebRelay. Synchronized payloads, taste data, and transferred audio files are end-to-end encrypted between paired devices.

Music Player supports encrypted backup export/import and local ML-related export data. Users can remove app data through Android settings, uninstall the app, remove paired devices in the app, and delete exported files or synced copies separately.

Magnetic Mapper

Magnetic Mapper does not use an account system or a developer-operated app server.

When a user starts a survey, the app processes precise location and magnetic or motion sensor readings. This can include GPS-related position data, magnetometer, gyroscope, accelerometer, device-pose, and step-detector values.

Survey readings, processed maps, and app settings are stored locally on the device. The app supports local JSON import and export.

Magnetic Mapper uses the Google Maps SDK for Android, which may send SDK and request metadata, device information, IP address, diagnostics, and related data to Google under Google's own privacy terms.

Users can delete individual readings or maps in the app, clear stored results, remove app data through Android settings, uninstall the app, and separately delete exported files or external backups.

Data sharing

• Data is not sold.
• Music Player network features are optional and only active when used by the user.
• Magnetic Mapper stores its own survey data locally unless the user explicitly exports it.
• Exported files, backups, and data copied to other devices remain under the control of the user and the chosen destination.
