I use the “download on demand” feature so that I can have everything (around 6000 items last time I checked) indexed and searchable in DTTG. It’s synced via my home Synology server’s WebDAV feature, so I can download anything I realize I need via IPv6 mobile connection.
I use it for pretty much everything except to do lists and calendar appointments. The key thing for me is that it’s end to end encrypted, and also encrypted at rest on all my devices. Because of that I am willing to put everything in it — tax records, medical information, personal journal entries, etc.
Lack of trust was the reason I gave up on Evernote — because everything ended up unencrypted on someone else’s server, I never felt I could put everything in it.
So I use it for everything I use the desktop version for. A few examples:
See something that would be a great gift for a specific person? Into DTTG tagged with “gifts” and the person’s name.
At the supermarket and forgot to add an ingredient to the shopping list? Pull up the recipe to check how much we need. (Did that last night.)
Seeing a medical specialist who wants to know exactly what a previous doctor diagnosed and when? Pull up the notes in DTTG.
Not sure how much to expect property taxes to be after refinancing? Pull up the last 2 years of tax returns.
Can’t remember where I put my backup hard drive? I jotted that down, a quick search and there’s the info.
Vehicle registration wants the car’s VIN? What was I vaccinated for in which years? Which Pink Floyd albums do I already have? What was the ID of that cool island in Animal Crossing? What is the longitude and latitude of our house to enter into this GPS? Which tag is the one AppleTV uses for the TV show name? How do I split a FLAC file using a cue file? What size replacement filters does the Shop Vac need? Where was that article about how to tie different kinds of knot? What is my shirt collar size? Who should I contact to rescue injured wild animals? Real examples of things I looked up in DTTG.
Basically, any time I have some information that I think I might want later, it goes into the database, because the risk is practically zero because of the security features, and the cost of entering the info is very low. So DTTG becomes the eidetic memory I wish I had.
