I don’t want my booking site disclosing my location to others who may use it to harm me, full stop. I have no idea what internal controls, if any, Sift or any other service provider has in place to screen their own staff or their own data handling procedures for safety. Even Equifax didn’t get this stuff right.

If I am telling a vendor where I sleep and when I am sleeping there, it is a huge breach of my privacy and safety for them to tell third parties without my explicit consent. This includes even relatively innocuous stuff, like database hosting. One disgruntled employee and a .torrent file later and many people’s lives or safety are put at risk.
