With a Promo.com subscription, none of the videos you will create, download or publish will have any mention of Promo.com, whether it is a watermark, text or any other form. The videos you will create will have your branding.
However, if you have Basic or Standard plan and decide to share a preview link with clients or partners, then they will reach a webpage, hosted on Promo.com which had the Promo.com branding and logo.
With Pro plan, you can enable White Label feature which allows you to customize your share link in such a way that if your clients open the link, they will not see our landing page nor our logo. For more information about White Label feature please click here.
