Approached for comment last week, Whisper said it “does not follow
or track users”. The company added that the suggestion it was
monitoring people without their consent, in an apparent breach of
its own terms of service, was “not true” and “false”.
But on Monday — four days after learning the Guardian intended to
publish this story — Whisper rewrote its terms of service; they
now explicitly permit the company to establish the broad location
of people who have disabled the app’s geolocation feature.
Whisper has developed an in-house mapping tool that allows its
staff to filter and search GPS data, pinpointing messages to
within 500 meters of where they were sent.
