Your conversations never leave your iPhone.
Orion has no server-side components. The language model, your prompts, conversations, and notes are processed and stored locally on your device. Delete the app, and its locally stored data is removed by iOS.
Read the privacy policyNone of this would be possible without open-source software. Orion is made possible by work from the Meta team behind Llama 3.2, the Dolphin team behind Dolphin 3, the Kokoro TTS team, the Swift open-source community, and the Google DeepMind team behind Gemma 4.
