Privacy Policy

2026-07-01

This Privacy Policy explains how S3Dock handles information. S3Dock is a user-configured Android client for S3-compatible storage. The app does not provide a cloud storage account and does not operate a developer-controlled server for storing user files.

Developer: haturatu.

Data Handled By The App

Depending on how you configure and use the app, S3Dock may store or process the following data on your device:

• S3-compatible endpoint, bucket name, region, access key ID, and secret access key
• File names, folder names, object sizes, modified dates, and media metadata
• Photos, videos, audio files, documents, and other files selected by you
• Local cache files, thumbnails, offline files, download history, favorites, scan folders, and playback state
• App settings, display preferences, provider presets, and saved storage accounts

The app may also access files, folders, media, notification permission, and foreground media playback capabilities when needed for features that you choose to use.

How Data Is Used

S3Dock uses this data to provide file browsing, media preview, media playback, upload, download, offline access, cache management, and storage management features.

S3Dock connects directly from your device to the S3-compatible endpoint configured by you. The app does not intentionally send your files, credentials, or storage metadata to the app developer.

S3Dock does not include advertising SDKs and does not use your data for advertising.

Permissions

S3Dock requests permissions only when they are needed for app features:

• Internet access is used to connect to the S3-compatible storage endpoint configured by you.
• Notification permission is used to show transfer progress and media playback controls where required by Android.
• Foreground service media playback permission is used only while playing audio selected by you.
• Storage write permission may be requested on older Android versions to save files to the public Downloads folder.
• Persisted folder access may be used when you select a local folder for folder upload.

Credentials

Storage credentials are stored locally on your device. The app uses local encrypted storage for saved credentials where supported by Android.

The app may provide explicit export options for device migration. If you choose a plain-text export option, credentials may be written into the exported file in plain text. Store such files securely and delete them when no longer needed.

Network Connections

Network requests are made to the endpoints you configure, such as Amazon S3, Cloudflare R2, MinIO, Wasabi, Backblaze B2, DigitalOcean Spaces, or other S3-compatible services.

HTTPS is recommended. HTTP endpoints may expose credentials, signed URLs, file contents, and metadata to the network and should only be used in trusted local environments.

External Apps

When you choose to open a file with another app, S3Dock may pass a temporary signed URL or local file URI to the selected external app. That external app handles the shared data according to its own policies.

Offline Files And Cache

S3Dock can save files for offline access and can cache thumbnails, media previews, listing data, and playback data locally on your device. You can clear cache and offline data from the app settings or by removing the app data from Android system settings.

Data Sharing

S3Dock does not intentionally sell, share, or transfer your data to the app developer. Data may be sent to the storage provider or external app selected and configured by you.

Data Deletion

You can remove saved providers, clear cache, delete offline files, delete exported backup files, and uninstall the app to remove local app data. Files stored in your S3-compatible storage remain under your control and must be managed through that storage provider or through the app.

Local app settings, saved providers, favorites, cache metadata, media indexes, offline selections, and playback state are retained on your device until you delete them in the app, clear app data, or uninstall the app. Cache files may also be removed when you clear cache from the app settings.

S3Dock does not provide an app account system. If you use an external S3-compatible storage provider, account deletion and remote data retention are controlled by that provider.

Children

S3Dock is a general-purpose storage client and is not directed to children.

Changes

This policy may be updated when app features or privacy practices change. The updated policy will be published on this page.
