We do not sell, rent, or trade your personal information. We share data only with:

We may disclose information if required by law, court order, or to protect the rights and safety of our users.

All the above categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties. We will not share your opt-in to an SMS campaign with any third party for purposes unrelated to providing you with the services of that campaign.

Your mobile information will not be sold or shared with third parties for promotional or marketing purposes.
