Overview

Barry is a macOS app that gives you per-app volume control. We believe in minimal data collection. Barry does not track your usage, record your audio, or sell your data.

What Barry accesses on your Mac

• Accessibility permission — Required to detect running apps and their audio output. Barry does not read screen content or keystrokes.
• Audio system — Barry uses Apple’s CoreAudio process-tap API to read each app’s audio in real time, adjust the volume, and re-emit it. macOS labels this capability as "audio capture" / "recording" access in its permission prompts, and it is what causes the small recording indicator next to the Control Center icon while Barry is running. No audio is recorded, written to disk, or transmitted.
• Licence storage — Barry stores your licence key and trial information in an encrypted file in its application support folder, mirrored to the macOS Keychain. This data never leaves your Mac except as described below.

Usage analytics

Barry has no analytics. There is no usage tracking, no event reporting, and no anonymous identifier. The only requests Barry makes are licence checks and update checks, both described below.

Payments

Checkout is hosted by Keylight, which creates a Stripe payment session and issues your licence key once payment succeeds. Card details are entered on Stripe’s own checkout page — Barry never sees or stores your card number, and neither does this website.

License validation

Barry’s licensing is powered by Keylight, a third-party licensing service. Barry contacts Keylight to activate, validate, and deactivate your licence.

These requests carry your licence key and an instance identifier, plus basic technical details used to tell your activations apart and to support them: Barry’s version, the licensing library’s version, your macOS version, and your Mac’s processor architecture, core count and memory size. No name, email address, file, or audio ever leaves your Mac. Validation is offline-first: Barry caches a signed lease so it does not need to reach the network on every launch.

Data retention

Licence and activation records are retained as long as the licence is active. If you deactivate a Mac, that activation record is removed.

Your rights

Since we don’t collect personal data, there is generally nothing to delete. If you have concerns, contact us and we’ll help.
