Privacy policy

Your audio stays on your Mac.

Last updated October 13, 2026

MixBar is designed to work without collecting personal information. Audio is processed locally, in memory, for the purpose of applying the volume and mute settings you choose.

Data controller

The data controller for the website, purchase records, and support requests is Nostar Sp. z o.o., registered office: ul. Półwiejska 17/26, 61-888 Poznań, Poland; KRS 0000992670; Tax ID (NIP) 7812040401. Use the contact form for privacy requests.

Audio

MixBar accesses outgoing application audio after you grant macOS System Audio Recording permission. Microphone controls read and change the selected macOS input device and its hardware gain; MixBar does not capture, save, transmit, or analyze microphone audio.

Saved settings

Application names, volume levels, mute states, selected output, and supported browser-tab preferences are stored locally on your Mac. Browser extensions also keep the settings necessary to restore captured-tab volume in that browser profile.

Browser access

Chrome and Opera tab control applies only to tabs that you explicitly choose through the MixBar extension. Safari tab control uses the bundled Safari extension and sends the current tab title, address, and media playback state only to the MixBar app on your Mac. Audio Autopilot scenes, triggers, and recovery snapshots are stored locally in macOS preferences. MixBar does not read browser history, bookmarks, passwords, or form data, and browser metadata is not uploaded.

Website and purchases

This website does not include advertising or first-party analytics. Checkout is hosted by Stripe. Stripe may process payment, billing, device, fraud-prevention, and tax information under its own privacy policy. Complete card details never enter the MixBar app, website, or release service.

After payment, the release service verifies the Stripe Checkout Session and streams the installer from private object storage. It receives the Checkout Session identifier needed for verification, but it does not receive complete card details or store audio data.

To let customers download the MixBar version they already purchased, the release service stores the checkout email address, Stripe purchase identifiers, purchased major version, purchase status, and purchase time. When you request another download, Resend processes that address to deliver a one-time link that expires after 15 minutes. Refunds and payment disputes disable the related entitlement. These purchase records are retained while needed to provide the perpetual license, meet legal obligations, and prevent fraud.

Contact

When you submit the contact form, Cloudflare Turnstile processes device and network signals to prevent abuse. Resend processes the name, reply address, topic, and message you submit so it can deliver your request to MixBar. The message is used only to respond to your request and is not added to a marketing list.
