Allowing Grammarly to track you across apps and websites will help prevent you from seeing Grammarly ads that don't apply to you and helps Grammarly understand the effectiveness of our marketing campaigns. Grammarly sends mobile campaign data to our analytics vendors, to determine the website domain or advertising campaign (if any) that referred you to Grammarly.
