According to Mobilize's privacy policy, they can hand over user information that users have voluntarily given them to law enforcement upon request.

“The privacy policies for Mobilize (part of Bonterra/NGP VAN) and similar platforms state that user data may be disclosed to law enforcement. The policies specify this can occur to comply with a "court order, law, or legal process, including to respond to any government or regulatory request." Some policies also include clauses allowing disclosure when there is a "good faith belief" it's necessary to investigate illegal activity or protect safety. This language confirms they can share data with government authorities, which aligns with the claim's assertion. Context: The claim implies a low legal threshold for data sharing. While the policies do require a legal basis, such as a government request or legal process, they do not exclusively require a warrant in all circumstances, and some allow for disclosure based on the company's own good faith belief of illegal activity.”
