Data and privacy

What you can put into Isa, where your data goes, and how it’s stored.

Isa is in alpha as a research product. Here’s what to keep in mind about the data you put in, where it goes, and how it’s stored.

Use only synthetic data

Isa is research software. Use synthetic (fake) patient data only. Do not enter real patient information.

Where your data goes

What leaves your phone depends on which model you run and which tools your Agent calls.

• On your phone: When the Primary Agent and Agents run on-device, and when you use Dictation or an on-device Scribe Agent, data stays on your phone.
• Off your phone: When you select a cloud model (OpenAI or aki.io) for the Primary Agent, when you use the cloud Scribe Agent (ElevenLabs), or when an Agent or the Primary Agent calls an MCP server, the relevant data leaves your phone.

You make this choice every time you pick a model or wire up an MCP server. See On-device vs. cloud for a deeper look at the trade-offs.

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.
