Which is exactly why the protocol is:
1. Your phone transmits a temporary random number.
2. Your phone stores, but never uploads, list of all the numbers it has seen for a prolonged period.
3. Your phone downloads daily a list of published numbers and cross-references that with the local list.
Literally the only time you upload anything is when you report being positive.
