Privacy Policy

Last updated: November 10, 2026

Video Grid Player ("the App") is designed with user privacy as a top priority. This policy explains what information the App handles and how.

1. Information handled by the App

1.1 Video files

• The App only reads video files that the user explicitly selects, either via Finder drag and drop or the file picker dialog.
• Video files are played on your Mac and are never transmitted externally.
• The App does not modify the video files themselves.
• macOS App Sandbox Security-Scoped Bookmarks are used so the App can continue to access the same files after restart.

1.2 Smart Playback analysis (Pro)

• Smart Playback (start when sound begins / start when a face appears) analyzes a video's audio and frames only on your Mac, using Apple's AVFoundation and Vision.
• The result (where to start playback) is used only inside the App and is never transmitted externally. Faces are detected only to find where a face appears; the App does not identify who they are.
• Results are kept in memory while the App is running and are not saved to files.

1.3 App settings

The following information is stored locally on your Mac (in UserDefaults and in files in the App's storage area):

• Custom keyboard shortcuts you have configured
• The tab last selected in the sidebar
• Open tabs and videos, layout, playback speed, and Smart Playback on/off
• The date you started the Pro free trial
• A record of your Pro subscription (plan and next renewal date), used right after launch
• The folder to open at launch
• Other app preferences (window state, etc.)

All of this data is stored on your Mac and is never transmitted externally.

2. Why no communication occurs

• The App is distributed via the Mac App Store under macOS App Sandbox, and its entitlements do not include network access (e.g. com.apple.security.network.client).
• As a result, network communication from the App to the Internet is technically blocked by the sandbox.
• No data is sent to analytics servers, advertising networks, or crash reporting services (apart from app receipt information handled by the Mac App Store).
• Pro purchases are handled by Apple's App Store. The developer does not receive your name, payment details, or similar information.

3. Disclosure to third parties

The App does not sell, lend, or share user information with any third party.

The App does NOT do any of the following:

• Access analytics or behavioral tracking
• Integration with advertising networks
• Automatic crash report transmission
• Collection of usage statistics

4. Data deletion

• For the Mac App Store version, settings data (in ~/Library/Containers) may remain after you delete the App. Remaining data is never transmitted off your Mac. To remove it completely, delete that folder.
• The App does not manage your video files; please delete them yourself via Finder or another tool if needed.

5. Changes to this policy

This policy may be updated without notice in response to changes in law or new features in the App. Significant changes will be communicated via app update release notes.
