Use only synthetic data
Where your data goes
What leaves your device depends on which model you run and which tools your Agent calls.- On your device: When the Primary Agent and Agents run on-device, when you use Dictation or an on-device Scribe Agent, and when OCR mode is Local only, data stays on your device.
- Off your device: When you select a cloud model (OpenAI or Aki.io) for the Primary Agent, when you route Scribe transcription to ElevenLabs or extraction to OpenAI or Aki.io, when OCR mode sends a scan to a cloud model, or when an Agent or the Primary Agent calls an MCP server, the relevant data leaves your device.
How patient data is stored
Patient data is stored encrypted on your device. There is no Isaree-hosted copy. This has two consequences worth keeping in mind:- Deleting Isa deletes every patient on the device with it. There is no cloud backup to restore from.
- Patients don’t sync between devices. A patient created on your iPhone won’t appear on your iPad or Mac.
