Is AI Journaling Private? What to Check Before You Trust One

A journal is where the unsaid things go. That makes "is it private" a load-bearing question rather than a box to tick — and it deserves a more useful answer than yes or no.

Start with the part that's true of every AI journal, including this one: your text has to be sent somewhere to be processed. There's no version where a model reads your entry without receiving it. Anyone claiming otherwise is describing something that isn't AI journaling.

What actually varies — enormously — is everything after that moment. Five questions get you the whole picture, and all five are answerable from a privacy policy in a couple of minutes.

1. Is the entry stored at all?

Some tools are pass-through: text goes out, a result comes back, nothing is kept. Others must store entries, because a journal that remembers is a journal that has to retain something.

Neither is wrong — they're different products. What matters is that the app tells you which it is, in a sentence, without hedging.

Lore: the free example on the homepage isn't stored. Your sentence goes to Anthropic solely to write that one chapter, and neither the entry nor the chapter is saved on Lore's servers. The full app does store entries and chapters — otherwise your story couldn't continue day to day.

2. Is it encrypted where it's stored?

"We take security seriously" is not a claim. "Entries are encrypted at rest" is. The first is a sentiment and the second is a fact someone can be held to.

Lore: entries and chapters in the full app are stored encrypted at rest.

3. Does your writing train a model?

This is the one people most want answered and the one most often left ambiguous. A clear policy says it plainly, one way or the other. Ambiguity here is rarely accidental.

Apps built on a major AI provider's API can usually point at the provider's terms as the reason they're in a position to promise it — which is a stronger answer than a promise made on its own.

Lore: your writing is never used to train AI models. Under Anthropic's API terms, data submitted through the API is not used to train or improve their models, and Lore doesn't sell your writing.

4. Can you get everything out?

Years of entries locked inside an app you can't export from aren't really yours. Export is also the best available insurance against a product being discontinued, acquired, or repriced.

Lore: you can export your full story from inside the app at any time.

5. Does deleting actually delete?

Some products treat "delete my account" as deactivation and keep the content. Those are materially different outcomes, and the policy is usually where the difference shows up.

Lore: you can permanently delete your account and all of its data at any time from within the app.

What else gets collected

Worth knowing, since it's rarely just entries. Lore records anonymous usage events — that a page was viewed or a chapter generated — along with a random browser ID, a one-way hashed version of your IP address, and your browser type. Those records don't contain the text you wrote, and a hashed IP can't be turned back into your IP address. If you join the early-access list, the email you type is stored so you can be told when the app launches.

The full privacy page is the authoritative version of all of this, including who operates Lore and how to request deletion by email. This article is a summary; where the two differ, the policy governs.

The honest comparison

The most private journal available is a paper notebook in a drawer. It has no terms of service and cannot change them. It also can't search, sync, survive a house fire, or hand you anything back — and the thing that kills most journals is getting nothing back.

So it's a trade, not a ranking. The reasonable approach is to know what you're trading: read the five answers above for whatever app you're considering, and if any of them is missing or written in adjectives, treat that as the answer.
