As title suggests, you can sort of take notes using the in-game chat without sending it to anyone else. If you click on your name, either after sending a message or in the player list of any given chat, it'll pop up with a Notes button, which will allow you to send messages to yourself for the purposes of (obviously) taking notes, copying fashions or builds of your own, or checking on items like mods or resources to see how much you have :)

I would include a screenshot, but TI also L'd that I can't *take* screenshots since I'm on Switch :/ I know DE is working on fixing that, so their work there is appreciated :)
