"Dumb" Heart Rate Monitor (information privacy)

Options:

  1. Standard Garmin (or similar)

-save workouts on the watch, but don’t let it sync with your phone/internet (the watch needs BTLE for the sensors, so probably turn off BTLE permissions in the phone app).

Just to clarify. You can turn the connection to the phone off on the watch. This is a separate setting to turning BTLE sensors on or off. And frankly, this is probably a better way to do it than turning the BT settings on the phone to off - at some stage you will leave the BT on the phone on for some reason (eg. listening to music), wander into range of the watch, and hey, presto, runs/rides uploaded.
