Overturn is made by NYRAI LLC ("we", "us"). Contact: hello@nyrai.ai.
This data is stored encrypted in the app's private storage and protected by your device passcode/biometrics. You can optionally require Face ID to open the app, and you can delete any case (and its documents) at any time.
To run the AI audit and draft an appeal, Overturn sends a tokenized,
de-identified version of your text to our server, which relays it to our AI
provider. Before anything leaves your device, identifiers — your name, member ID, claim
number, address, provider and insurer names, and patterns like SSN/phone/email — are
replaced with neutral placeholders (e.g. {{PATIENT_NAME}}). A safety check is
designed to block the request if a recognized identifier is still present, though no
automated de-identification is perfect. The real values are re-inserted
into your letter locally on your device; they never reach our servers.
We do not store your medical documents, the text of your bills, or any protected health information on our servers.
De-identified text is processed by our AI provider (Anthropic) solely to generate your audit and letter. We seek no-training / no-retention handling for these requests. The AI is instructed to use only the facts you provide and to never invent diagnoses, amounts, or legal citations.
We do not track you across other apps or websites and we do not sell your data. We use Supabase (auth, entitlement storage) and Anthropic (AI) as processors, plus Apple for in-app purchases.
Overturn is not directed to children under 13 and is rated 17+.
We'll update this page and the "last updated" date for material changes.
