We want to try and convey:
Your data is your data. You’re just storing it in Customer.io so we can use it to provide you a service.
To provide you with service, we need to share some things that are end-user PII with third parties. For example we need to share someone’s email address with our partner Sendgrid in order send an email to them. But there’s no way in heck we’re ever going to be doing sketchy things like selling your data!
We worked with our lawyer to update the language and make it clearer.
