We share Personal Information about our users with third party advertising companies, including social media companies, so they can learn about the kinds of audiences that use our products and display advertisements for our services to them and users similar to them.

We may use Ad networks such as Google Ads and Meta and their associated tracking technologies to help display the Permission Slip ads you may see on other apps and websites, and to help us manage and optimize our advertising efforts. To opt out of Google Ads, you can visit Google’s Ad Settings page. To opt out of receiving behavior-based ads from Meta, you can visit Meta’s ad settings page.
