This is sweet and lovely. I do this in two different ways - I send occasional emails to their IDs and write their journals in plain text.<p>I created their email IDs on my family’s domain so I can transfer them to whichever service provider fits them best. Right now, it is Google Workspace. For those mentioning about Google freezing your account accidentally, I’ve set Thunderbird to download a copy regularly. This is where I can search for emails from 20+ years ago and still reply or re-initiaite a conversation.<p>For the plain text, I write in the simplest form spiced up with some Markdown such as headings, lists, and the other basic formatting that are human readable. I also add static assets, such as the very funny and super cute images, audio, video, etc., in a folder for references to the journal entries.<p>All of these digital content for my daughters are in a separate folder with a few sub-folders. The day they want it, I will just give them a folder for them to continue from there.<p>My first daughter is a teenager now, and she is even more privacy-conscious than me. She has onions layers of personas for her online avatars -- be it for games, school friends, and other online friends. She is adamantly against using AI for creative processes, such as generative AI, though she uses ChatGPT regularly for her studies.<p>Own the content, while using other hosted or third-party services and have a backup. Be ready with the answer to, “How can I walk out of this?”
