[Personal headcanon] Gallifreyan
Disclaimer: As the title says this is just how I think of and use what I consider to be the main fan created Gallifreyan font/languages. This is not me attempting impose it on everyone else as a definitive organisation just as reference for my work following this to avoid confusion.

Timelord Circular/History coding: (Doctor's Cot) http://doctorscotgallifreyan.com/
Faction Paradox Circular/alt time coding: (Shermans) https://shermansplanet.com/gallifreyan/
Faction Paradox Circular/alt time coding is used by sme renegades as an act of defience hence the Doctor's ocassional onscreen use of it. It's like an Eton alumni, "rebelling" purposely using americanisms in an Austrailian accent. instead of the proper English language in a London accent as taught: Paradox/Rebel Circular Gallifreyan.
