Netguard is your friend (Android only though).
We're all screwed soon and will be living in daily fear of our codes turning yellow like the other 1.4bn over the border
I wonder how that feature would have worked... i.e. it uploads each check-in as they happen, or the accumulated "queue" is periodically sent during a scheduled data dump.
- and if the latter, whether it means that by defaulting to "ON", we have unwittingly already uploaded everything in cache before we managed to turn it off. This would be extremely cunning indeed.
I am quite sure I imported the name and ID free image from IAMSmart. But I also don't operate on the level of paranoia of the usual suspects in Twitter..
Try it after you get vaxxed..
Just enabling the Health Code system in the app does nothing. You must register for a health-code account, activate it, log in through the LHS app and then press a button to upload your travel history from LHS to the health code system.
