Privacy Policy for FastMediaSorter

Last updated: November 30, 2025

Overview

FastMediaSorter is a media manager and slideshow application for local, network, and cloud storage. We are committed to protecting your privacy and operating transparently.

Data Collection and Storage

What Data We Access

FastMediaSorter accesses the following data only on your device and configured storage:

1. Local Storage
   • Photos, videos, audio files on device and SD cards
   • Used only for displaying, sorting, and organizing media
2. Network Storage (Optional - User Configured)
   • SMB/CIFS, SFTP, FTP server credentials you provide
   • File metadata from network shares
   • Direct connections from your device to your servers
3. Cloud Storage (Optional - Google Drive, OneDrive, Dropbox)
   • File metadata: names, sizes, thumbnails, modification dates
   • Account email (for authentication display)
   • Limited to folders you explicitly select
   • OAuth tokens for authenticated access
4. Location (Optional - Network Monitor)
   • A GNSS track only while you turn on its separate setting and keep the Monitor’s Satellites screen open
   • Stored on your device; it does not start in the background or leave the app unless you explicitly share its file

What We Store Locally

All data stored in app’s private, encrypted storage:

• Connection settings: server addresses, paths, credentials (encrypted)
• User preferences: language, sort order, playback settings
• Thumbnail cache: temporary images for faster loading
• Database: resource configurations, file metadata cache

What We DO NOT Collect or Share

• ❌ No analytics or usage tracking
• ❌ No advertising data
• ❌ No behavioral tracking
• ❌ No background location tracking
• ❌ No personal information (names, emails, phone numbers)
• ❌ No servers: Your data never goes to our servers (we don’t have any)
• ❌ No third-party data sharing

Logging and Debug Files

• In DEBUG builds the app may optionally write diagnostic logs to a file in the app-specific external storage directory to help troubleshooting when ADB is not available.
  - Location (example): /Android/data/com.sza.fastmediasorter.debug/files/logs/ on the device storage.
  - These log files may include timestamps, log levels, component tags, and messages produced by the app and may include non-sensitive metadata such as file names and server addresses used by the app during operation.
  - Logs do NOT contain stored passwords in plaintext (sensitive credentials are handled using secure storage).
  - File logging is only enabled in debug builds and can be disabled by using the release build or by changing debug settings.

Cloud Storage Integration (Google Drive, OneDrive, Dropbox)

When you connect cloud storage (optional):

Authentication

• Uses OAuth 2.0 for secure sign-in (Google, Microsoft, Dropbox)
• You control which folders the app can access
• Tokens stored encrypted on your device only

What We Access

• File metadata: names, sizes, thumbnails, modification dates
• File content: only when you view/copy/move files
• Your email address: displayed in UI for account identification

What We DON’T Do

• ❌ Access files outside folders you select
• ❌ Share your cloud data with anyone
• ❌ Upload your data to our servers
• ❌ Scan your entire cloud storage
• ❌ Access other cloud services of that account (Gmail, Google Contacts, Calendar, etc.) - the optional on-device contacts permission below is separate and never reaches your cloud account

Data Usage

• Thumbnails cached locally for performance
• File operations happen directly: Device ↔ Cloud Provider
• No intermediary servers or proxies

Revoking Access

Disconnect anytime:

• In app: Settings → Cloud Resources → Sign Out
• Google Account: Manage Permissions
• Microsoft Account: App Permissions
• Dropbox: Connected Apps

Provider Privacy Policies

Cloud access is subject to each provider’s privacy policy:

• Google Privacy Policy
• Microsoft Privacy Statement
• Dropbox Privacy Policy

Network Access

Local Network (SMB/SFTP/FTP)

• Direct connections from device to your servers
• Credentials encrypted using Android Keystore
• No intermediary services or proxies
• Data never leaves your local network

Internet Usage

• Google Drive API: only for authenticated access to your files
• External IP check: only after you ask for it, the Network Monitor contacts a third-party IP-echo service that can see your request address; the result is shown on screen and is not automatically saved
• No telemetry, analytics, or tracking servers
• All operations are user-initiated

Permissions Explained

This section lists everything the app can ask you about - each permission granted through a system dialog or through a dedicated system screen. Permissions granted silently at install, which you are never asked about (network access, vibration, keeping the screen awake, foreground service types), are not listed.

Your build may show fewer of these than the list: a permission appears only when the feature behind it exists in that build, and Settings > Permissions always shows exactly the ones your build can ask for.

Storage

• READ_EXTERNAL_STORAGE: Find and show media files on the device (Android 6-12)
• WRITE_EXTERNAL_STORAGE: Move and delete files you sort (Android 6-9)
• READ_MEDIA_IMAGES / READ_MEDIA_VIDEO / READ_MEDIA_AUDIO: The same access, split by media type (Android 13+)
• MANAGE_EXTERNAL_STORAGE: Optional. Granted on a system screen. Lets you pick any folder, including DCIM, Camera and app folders such as Android/media, instead of only Documents, Downloads and Pictures
• MANAGE_MEDIA: Optional. Granted on a system screen. Lets media moves and deletions go through without a separate confirmation each time (Android 12+)

Network

• ACCESS_LOCAL_NETWORK: Optional. Reach SMB, SFTP, FTP and DLNA servers on your own network, and find them by looking for devices on it. Android introduces this permission in a release later than any shipped today, so no current Android version asks you for it

Camera, microphone and location

• CAMERA: Optional. Shoot photos and video inside the app, recognize text, and scan a companion QR code
• RECORD_AUDIO: Optional. Record voice notes and the sound in a screen recording
• ACCESS_FINE_LOCATION / ACCESS_COARSE_LOCATION: Optional. Four features read it. It writes coordinates into the photos and videos you shoot in the app; on the launcher desktop, it gives the compass, speed and chart gadgets your speed and altitude while one of those tiles is on screen; and the Network Monitor can record a GNSS track only while its Satellites screen is open and you turned on the separate track setting. The fourth is the name of the Wi-Fi network you are connected to, shown in the Monitor’s Wi-Fi section: Android treats that name as location data and hides it from every app without this permission, so the row says why instead of showing it. Position is never read in the background. Charts and an opted-in track stay on this device; nothing is sent anywhere unless you explicitly share a track file. Denying it leaves captures without coordinates and those tiles idle with a message saying so

Notifications

• POST_NOTIFICATIONS: Optional. Show playback, transfer and recording progress, and the notification that carries their stop control (Android 13+)

System

• SYSTEM_ALERT_WINDOW: Optional. Granted on a system screen. Draw the edge-gesture strip over other apps
• REQUEST_IGNORE_BATTERY_OPTIMIZATIONS: Optional. Granted on a system screen. Keep scheduled operations running on time instead of being paused in the background
• REQUEST_INSTALL_PACKAGES: Optional. Granted on a system screen. Install an APK file you opened from a browsed folder. Present only in the build without legal restrictions
• Screen capture consent: asked again by the system every time a screen recording starts, so it cannot be granted in advance. The app declares FOREGROUND_SERVICE_MEDIA_PROJECTION to keep the recording alive while it runs
• READ_PHONE_STATE: Optional. Show the SIM signal level in the launcher’s own status area. The level is read on the device and never leaves it - nothing is stored, sent, or shared. Denying it hides both SIM indicators and changes nothing else
• BIND_NOTIFICATION_LISTENER_SERVICE: Optional. Turned on by you on a system screen. Serves two features of the launcher desktop, and nothing else. First, the Now Playing gadget shows and controls what other apps are playing, reading media sessions only. Second, if you switch it on yourself in the launcher settings, the top bar shows one icon per app that currently has notifications waiting, together with how many it has - the app reads which application posted a notification and how many are pending, never their title, text, attachments or actions. Both features are off until you turn them on, nothing about a notification is written to storage, and nothing leaves the device
• READ_CONTACTS: Optional. Show a pinned contact’s name and photo on the launcher; denying it keeps a plain initial in place of the photo
• ACTIVITY_RECOGNITION: Optional. Asked only when you add the steps gadget to the launcher desktop. The count comes from the counter your phone already keeps, is read only while the tile is on screen, and is neither stored by the app nor sent anywhere. Denying it leaves the tile idle with a message saying so
