Is my journal private if it uses AI?
Short answer
It can be private, but there is a trade you should understand. For AI to surface your emotions and patterns, it has to read your writing, usually on a server. Privacy then comes down to three promises: no training on your entries, no selling your data, and the ability to export and delete everything.
In depth
The word private gets stretched in this space. Almost every app encrypts your data, and many stop there as if that settles it. It does not. Encryption protects your entries from outsiders, but the company running the AI still reads them to do the analysis. That is the part marketing tends to gloss over.
So before you trust an AI journal with your most honest writing, check four things. Do they train their models on your entries? Do they sell or share your data? Can you export everything in a portable format and delete it for good? And who is the AI provider behind the scenes, since their data policy matters as much as the app's?
Pensio reads your writing to analyze it, which it has to, but never trains on your entries without consent and never sells your data. It encrypts at rest and in transit, exports to plain Markdown, and deletes on request. For the most private setup, it syncs with a local Obsidian vault so your files stay on your own machine.
