Privacy through Architecture
I. We do not record your words.
With the OKhuman app, your words never leave your device. Without your words, the proof stays locked. We store only a representation of your text, one that cannot be reversed back to your words.
II. We hear you typing. Nothing else.
OKhuman uses your microphone intermittently for one thing: to hear your keyboard clicks that prove you wrote the words. Without this signal, someone can use an "auto-typer" to simulate the human writing process. The microphone signal gives us real-world, irrefutable proof of human writing.
We remove human voices from the sound signal before it is transmitted to OKhuman servers for evaluation. Our servers use the signal to generate your proof, then destroy the signal immediately.
III. How this compares.
There are other writing proof tools. These record your words, they record keystrokes, track every edit, and build a replayable record of your entire writing session. The result is a surveillance record that places no importance on the writers' privacy.
OKhuman serves the writer. We designed the architecture so that we cannot access your text. We cannot read your writing. This means we can't fulfill a request to uncover what you wrote and that we don't build AI models trained on your words. We built the system with privacy first as an architectural choice.
