"Erase all my data" button.

[Carreau]

This one is technically unnecessary of you understand how jupyterLite work, though this is more a question of User-interface than anything else.

We had a couple of request on the security mailing list of people asking us to "delete [their] data from [our] servers", in particular some quite panicked folks that had uploaded medical information and got their finger slapped.

User don't make the difference, or don't understand that the data is in their browser, and when they come back and see that files are still there, they may panic.

I suggest we add a button "Erase all my data", that pop up a dialog with:

• a short explanation that no data is collected and everything is store on the current computer.
• a "Erase all my data" (that clean any local storage or relevant).

I don't think it is pressing, but if this get a more usage we might start to have requests.

Alternatively we should have the "Go back" button discard the data as well and/or automatically discard on next usage if more than a certain amount of time as passed (potentially with warning), that would avoid the opposite case where someone assume it's persited, and lose work after a page refresh, or a browser update.

Yeah this is also a popular request in JupyterLite itself: jupyterlite/jupyterlite#9

Two possible ways forward:

• Fix Add a plugin to clear settings jupyterlite#9, which should be done anyway at some point
• Provide documentation in jupyterlite-sphinx to make it more visible how to use volatile memory storage: https://jupyterlite.readthedocs.io/en/stable/howto/configure/storage.html#volatile-memory-storage
  • or make it the default in jupyterlite-sphinx?

I guess once this is in JupyterLite, we can just have a hook to have say a link in the documentation footer when using jupyterlite-sphinx, that allow to erase w/o having to actually launch jupyter-lite. I think that not everyone will think at launching and then erasing.
