How long does SharePoint Online keep data for who has opened a file?

Copper Contributor

When a SharePoint site has "SharePoint Viewers" activated in the "Mange Site Features" section, you are able to see who opened the file. 

 

How long does this data stay around? I also have seen in the past that it showed the amount of time the user had the file open for, but I cannot seem to find that after we migrated tenants. 

 

Any help is greatly appreciated!

I have the same question as ComCov. Does anyone has an idea? Thanks.
