Is LeadBook safe?
LeadBook sends Facebook profile names to an AWS Lambda endpoint when gender, country, or tier filters are enabled.
LeadBook parses names from Facebook profile, group, member, or friend pages and uses them when its filtering features are turned on. For gender, country, or tier filters, it sends the parsed name in a POST request to a LeadBook-configured AWS Lambda endpoint and uses the response to decide whether the profile matches the filter.

Where it sends data
Destinations our analysis observed LeadBook contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
