Most AI apps quietly send your data to the cloud. DiaryGPT does the opposite — and this is the full technical story.
The Problem With AI + Private Data
When you write in a journal, you write the things you'd never say out loud. The last thing you want is that text sitting on someone else's server, used to train a model, or exposed in a breach.
But AI is genuinely useful for journaling. It can find patterns you miss, reflect things back to you, ask questions a blank page never would. The tension is real: you want AI insight without sacrificing privacy.
Most apps solve this by trusting a privacy policy. I wanted a technical guarantee.
