When installing Boostflow apps for the first time, you may see the Boostflow trademark above all Boostflow widgets (Sales notifications or Countdown Tools...)
We have the Power User program which allows store owners to remove Boostflow brand once activated. As a promotion, you can activate the Power User program for free and by yourself.
Simply go to App Admin >> Start Guide >> Scroll down to Power User section and click Activate Power User for FREE.
Adding the brand on the notifications is actually for copyright protection reason, most especially since the app is for free, but you can remove it if you want by using the instruction above.
Let us know if you need more assistance.
