Saying "I don't do social media" isn't bragging. It might make people interrogate their own habits, which can provoke a negative reaction, but that's on them and any response would do that, so there is nothing to be done about it. Either way it's not bragging. Say it in a light tone/with a smile so people know it's just meant as a nice thing. Consider providing an alternative, which will also soften the blow, because it makes it clear that you just dont do social media.

Do not worry about seeming "old". It's quaint and also something you can joke about, which makes for a good conversation. Consider providing your alternative (if it's a phone number) alongside a recognition that it is atypical/old-fashioned, to get ahead of the perception you're afraid of - It lets you control the narrative. It can also help with your worries about wether or not you're being perceived as "old" because you yourself bring it up.

Don't talk about privacy or opsec unless people ask into it, and keep it surface level and let people themselves ask more questions.

Edit: let me know if you want a tone indicator or have any clarifying questions
