What do you, personally, use for archiving* Signal messages, including media, which are currently showing in the Signal app?

Do you have a personal recommendation for something which works on Linux or Android, please?

Bonus marks if one can specify a date range, rather than needing to tag individual messages.

* i.e. storing outside the Signal app/its database, in a directory of my choosing, perhaps in html or at least PDF
