Privacy
Updated October 6, 2026. Berth is a free Mac app made by Cohen Coolidge. It has no accounts, no analytics and no servers of its own.
What stays on your Mac
Your docks, widget settings and notes are saved in a file in your Library folder. Clipboard history stays in memory and is never written to disk. Berth sends none of this anywhere.
Connected services
When you connect a service, Berth stores its key or sign-in token in your Mac’s Keychain. Berth uses it only to read the numbers that service’s widget shows, by calling that service directly from your Mac. Nothing passes through any other server. Disconnecting a service removes its key from the Keychain.
If you sign in with Google, Berth asks for read-only access to Google Analytics, Search Console and Google Tasks, and for your email address so Settings can show which account is signed in. Berth uses this access only to show your active users, search clicks and open tasks in its widgets. It never writes, deletes or shares your Google data, never uses it for advertising, and never sends it anywhere other than your own Mac. Berth’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. You can remove access at any time with Sign Out of Google in Berth, or from your Google account permissions.
Bank accounts
Bank balances come through SimpleFIN, which you sign up for yourself. Berth keeps the read-only access link SimpleFIN gives it in your Keychain and reads balances and today’s transactions to show in the widget.
Other widgets
Weather comes from Open-Meteo, stock prices from Yahoo Finance and crypto prices from CoinGecko. Those requests include only the city, ticker or coin you chose. Calendar, Reminders, Now Playing and Mail read from apps on your Mac after macOS asks for your permission.
