Do AI journaling apps train their AI on my entries?
Short answer
Some do, unless you opt out. Others promise they never will. Your journal entries can become training data for a model, or part of a profile that a breach could expose, so this is worth two minutes of checking before you start.
In depth
Why it happens: AI features need data, and your entries are unusually rich data. The temptation to use them, to improve the model or to learn about you, is real. The difference between apps is whether they resist it and say so plainly.
To check fast, read the privacy policy and terms for the words train, improve our models, or profile. If it is vague, treat that as a yes. Look for an explicit promise, not a vibe. Turn on any opt-out if they do use your data. And remember the model provider too: if the app sends your text to a third-party AI, that provider's data policy matters as much as the app's.
Pensio's line is simple. It does not train models on your entries without your explicit consent, and it never sells your data. The AI reads your writing to analyze it, which it has to, but nothing you write becomes training fuel or an ad profile. If an app cannot give you a straight answer to this question, that is your answer.
People also ask
Is AI journaling private and safe?
It can be, but "encrypted" is not the question. Who reads it, do they train on it, can you leave?
Does the AI run on my device or on a server?
Most process your entries on a server; a few run on-device. On-device is more private, server-side is usually smarter.
What is the most private AI journaling app?
The most private is local and offline. Among cloud AI journals, judge by no-train, no-sell, full export.
