Privacy Policy

Effective 22 October 2026

This policy covers Brink (on the Mac App Store as “Brink Bar”), Brink Terminal Helper, and this website, brinkbar.com. They are made by Cynaptic Technologies LLC (“we”, “us”).

In short:

  • Your notes, task lists and settings stay on your Mac. We never see them.
  • Brink makes no network requests of its own. No account, no analytics, no tracking, no crash-reporting SDK, no ads.
  • Purchases go through Apple’s App Store. We never receive your payment details.
  • This website sets no cookies and runs no analytics or scripts.

Brink, the app

Your notes stay on your Mac

Notes, task lists and settings are stored only on your Mac, in Brink’s App Sandbox container. Time Machine backs them up along with the rest of your Mac. Nothing syncs to other devices or to any server, ours included, and we have no way to read them.

No data collection

Brink doesn’t make network requests of its own. It has no analytics, no tracking, no advertising, no crash-reporting SDK and no accounts. We don’t collect, sell or share personal information, because Brink doesn’t send us any.

Rendered notes and links

When Brink shows a note formatted, it loads nothing from the network: an image from the web appears as a link instead, so opening a note never tells a server you read it. Links you click in a note open in your browser (or the app they belong to).

Spotlight

Your notes and task lists appear in your Mac’s own Spotlight index, so you can find them from Spotlight. That index is on your Mac.

Permissions Brink asks for

Each of these is asked for only when you use the feature that needs it, and you can turn it off in System Settings › Privacy & Security at any time.

  • Input Monitoring, for opening Brink with a double-tap of ⌘. Brink watches only modifier keys, to notice the double tap. It doesn’t record or store your keystrokes. A keyboard shortcut works without this permission.
  • Calendars, for calendar tabs, and Reminders, for reminders tabs (Brink Pro). Brink reads your calendars, and reads and changes your reminders, through Apple’s EventKit on your Mac, only after you grant access. That data goes nowhere else.
  • Folders, for folder tabs (Brink Pro). Brink shows only the folders you pick, and doesn’t change their contents.

Purchases and the free trial

Brink Pro and its free trial go through Apple’s App Store. We never receive your payment card details. Apple shares only aggregate sales and report data with developers, not who you are.

Crash reports and usage statistics

Brink sends no crash reports itself. If you choose, in your Mac’s settings, to share analytics with app developers, Apple may share crash reports and usage statistics with us. That’s Apple’s feature and your choice; it’s off unless you turn it on.

Brink Terminal Helper

Brink Terminal Helper runs the shells for Brink’s terminal tabs, on your Mac. It talks only to Brink, locally, and sends nothing anywhere. What your shell itself does (the commands you run) is up to you, as in any terminal.

This website

brinkbar.com sets no cookies, runs no analytics and loads no third-party scripts. Two things to know:

  • Server logs. The company that hosts the site may keep standard server logs, such as your IP address, the time and the page requested, as web servers do.
  • Fonts. The headings use fonts served by Google Fonts, so your browser asks Google for them, which tells Google your IP address. We don’t use Google Fonts to track you, and no cookies are involved.

If you email us

When you write to support, we receive your email address and whatever you send, and use them only to answer you. We don’t add you to a mailing list or share your message.

Children

Brink collects no personal information from anyone, children included.

Changes to this policy

If this policy changes, we’ll post the new version on this page with a new effective date. If Brink ever starts sending any data anywhere (for example, if sync is added), this policy will say so before that version ships.
