Uninstalling the extension will not cancel any subscriptions you have. It's our suggestion to cancel your subscription before uninstalling to prevent any unintended charges from recurring.
There are two different ways you may have installed Streak. Each installation needs to be removed separately:
Browser extension: installed only on your local desktop computer
Gmail add on: installed directly on your Gmail account, available everywhere (including mobile) you use Gmail
1. Removing Browser Extensions
Navigate to your Extensions (chrome://extensions) from the top-right three dot menu, under "More Tools"
Scroll to find Streak in your list of extensions
Select the Remove option
Confirm by clicking Remove in the new alert window Chrome has opened.
After removal, you may need to refresh Gmail (hint: while viewing Gmail, press 'F5' on Windows or 'Command+R' on a Mac).
Click Safari in the upper left-hand side of your screen and select Preferences from the dropdown menu
In the new window, open the Extensions tab
Go to your Applications folder and uninstall the Streak application (you can do this by dragging the Streak application icon to the trash bin).
Go back to the Extensions tab under Preferences and click on Streak and select "Uninstall". Do the same for "Streak Helper". You may need to restart Safari for the changes to take place.
Google Apps (all browsers managed by your G Suite account)
If you have a Streak for Google Apps account, you will also need to remove Streak from within your Google Apps administration panel.
Access your Google Apps admin console by clicking the Google Apps settings gear icon and selecting Manage This Domain
Select Marketplace Apps
Click the Streak link
Click the "Remove App" icon.
2. Removing the Gmail Add-on
Streak's add-on for Gmail can be managed from your Gmail Settings, under the Add-ons tab.
If you're a G Suite user, you may need your team admin to remove the add-on for you.
Open your Gmail Settings and select the Add-ons tab
In the left column, click the Manage link under Installed add-ons
Click the three-dot More menu and select Remove from the two options.
3. Deauthorize Streak from your Google Account
Log into the Gmail you'd like to remove Streak from
Navigate to the Permissions page of that account
Find Streak in the list of Third-party apps with account access and click the entry
Select Remove Access
Refresh your Gmail
