Our commitments, up front

  • We will never sell your data. Not anonymised, not aggregated, not "shared with partners." Never.
  • We will never use your data to train third-party AI models without explicit opt-in. Meal photos default to a 24-hour TTL.
  • You can delete your account in one tap. All associated data is purged within 30 days.
  • We BAA with every subprocessor that touches PHI. The list is public and dated.

What we collect

Dia AI is designed to collect the minimum data necessary to deliver the product. That is:

  • Sign in with Apple identifier — a stable, opaque Apple ID. We do not see your email unless you elect to share it.
  • Meal photos — sent to Anthropic Claude Vision for analysis. Deleted from our object storage within 24 hours by default. You can opt in to permanent retention to help us improve the model; you can opt out at any time.
  • Health data you choose to log: carbs, insulin, blood glucose, exercise. Stored encrypted at rest and only ever associated with your Apple ID.
  • Apple Health data read through HealthKit — never leaves your device unless you explicitly share a report.
  • Diagnostic crash data through Sentry. Stripped of PHI before it leaves your device.
  • Product analytics through PostHog (self-hosted EU). Counts and feature usage. No PHI, no third-party advertising identifiers.

What we don't collect

  • Your email or phone number, unless you elect to share them.
  • Third-party advertising identifiers (no IDFA, no fingerprinting).
  • Your contacts, photo library, or location history.
  • Any data we don't strictly need to deliver the product.

Where your data lives

Production storage is on AWS US-East-1 (default) or AWS Frankfurt (for EU users). Image storage uses Cloudflare R2 with a 24-hour TTL by default. See the subprocessor list for the complete breakdown.

Children

Dia AI is not directed at children under 13. We do not knowingly collect data from anyone under 13. Caregivers managing a child's diabetes use their own Apple ID and explicitly link the relationship.

Decision support, not medical advice

Dia AI is a decision-support tool. The carb estimates, the bolus calculator, and the reports are informational. Verify every dose with your care team and use your clinical judgement. Dia AI does not transmit doses to pumps.
