1. The In-app-purchase gives you inking, linking by drawing lines, freeform excerpts, multiple documents in a single project, and more. 2. Sign-up required: no. 3. Does this require 3rd party servers: no, stores everything locally.

Happy to answer any other questions (I'm founder @ LT)!

Is there any way to export the data into a standard, editable file format? (Ideally something like markdown...)? I hate to build up a huge library of notes that are only usable in one piece of software...

Yes, even in the free version, export as PDF (higher fidelity), or export notes as an outline in DOCX for easy editing in Word.
