🔒 PRIVATE BY DESIGN

Your files are yours.

OpenAny is built with privacy at its core:

• No account or sign-up required
• No advertisements
• No trackers
• No analytics
• No cloud uploads
• No file synchronization
• No internet access required
• No unnecessary storage permission

Files are opened through Android's system file picker or your device's "Open with" functionality.

Your documents remain on your device and are processed locally.

OpenAny does not upload your files to a server or require an online account to view them.

Only the permissions required for media playback may be requested, such as notifications and foreground playback functionality. These permissions do not provide OpenAny with access to your personal files.
