Hi, thank you for checking and correcting my manuscript. I have two questions concerning corrections I hesistate to implement:

- Correction= "When an app user identifies themselves as being infected by COVID-19, the user is asked to share their list of locally saved tokens with a central server. " can I use "app user" with "themselves"? Or the following phrase: "When an app user identifies as being infected by COVID-19, the user is asked to share the list of locally saved tokens with a central server. "

- Correction= "Part of some countries’ deconfinement policies include the use of apps that focus on contact tracing." or? >> "part of... are the use of apps" or other phrasing? (I hesitate to use "part of... include".

Thank you.

Best wishes,
