I think the individual apps on top of the same framework are not identical in the way the data is collected and stored. AFAIK in some countries they have a centralized database, whereas e.g. in Germany all contact IDs are kept locally and only compared to a published (but anonymized) list of infected IDs.

No, that's not the difference. The contacts are stored inside the system's framework.

The difference is in how people report themselves as infected. That has to match the country's process for verification of the result.
