Cancers you have never been diagnosed with

What this app does with your information

Never use, store, log, or display real PHI/PII. Fictional/synthetic screening data only. On-device privacy claims must not be backed by real patient records. The short version of the product claim: compute is intended to stay on this device. This preview works only on canned synthetic figures — never a real chart — and does not send them to a server. Three future leavers are named below rather than left out; none of them fire here.

What is kept, and where

• cka.demo.v1

  The only key this preview writes: { synthetic: true, profileId: "demo-001" }

• cka.profile.v1

  Named for a future build. Not written here. Never a real profile.

• cka.plan.v1

  Named for a future build. Not written here.

• cka.record.v1

  Named for a future build. Not written here.

The three things that leave

• The records-request letter

  Named for a future build. This preview does not write a letter, collect a name, or contact a hospital.

• A visit packet you share

  Named for a future build. This preview has no share action and sends nothing.

• Optional crash text

  Named for a future build. This preview has no telemetry and no crash pipeline.
