I like the concept, but I bailed at "GPT 5". The only thing that has given me peace of mind and the ability to journal honestly and successfully is Obsidian, because it lets me own my data (as text files).

Thanks for the feedback. I love Obsidian. All your data is stored on device i.e., in calendar entries (a Dlog is saved in your default calendar, that's why you don't need to sign in to use Dlog; the title and text of a calendar event are repurposed in Dlog to be a journal; much like the reminders have been repurposed to comprise projects) and on the in app on device Rag database, it is not stored in the cloud etc., so you do own all the data; and it is not shared to the Dlog server which is only used to track token usage. GPT 5 is necessary for the moment; Dlog uses the enterprise API, so it doesn't train on your data. However, I know this is a major concern for many, so, in the short term I will be adding an anonymiser; and the ability to approve and edit prompts sent. If you do decide to sign up to use Dlog send me a DM with the email used to register and I'll send you a free perpetual license so Dlog will always be free (excluding tokens for AI use) and 1 million free tokens. Thanks again!
