Trust Center

Privacy is the product.
Here's how we prove it.

Every architectural choice, every subprocessor, every compliance document, in one place. No legalese in the headlines — full detail in the linked docs.

What never leaves your laptop

Every stage of the loop runs on the machine the audio is already on.

Your machine

No cloud-processing path

  1. Drop in

    Audio or video, from your Mac, Windows, or Linux machine.

  2. Transcribe

    Whisper large-v3 turbo, running on that same machine.

  3. File

    Into an encrypted kajo.db — your local library.

  4. Ask

    Translation, summaries, and cited chat — one on-device Gemma 4 model, over that same library.

The default install never crosses the network with audio. There is no cloud-processing path — transcription, translation, summaries, and cited chat all run on your machine.

Three pillars

  1. Local-first / private by default

    Your audio never leaves your laptop.

    Audio is transcribed on-device — there is no cloud-processing path. Private by architecture.

  2. Cross-platform, including Linux

    Mac, Windows, and Linux — one product, three operating systems.

    Native installers for all three. Linux is a first-class target, not a port — the only local audio knowledge base that takes it seriously.

  3. Cited chat

    Ask questions across your archive — get cited answers.

    Chat with your entire library using a local model. Every answer links back to the exact moment in the recording — no copy/paste.

Compliance

Compliance is not the same as privacy — but it is the contract layer that makes privacy enforceable. Here is exactly what we publish today.

Local-only architecture

Audio and transcripts stay on your device — there is no cloud-processing path.
