Privacy and terms
Plain rules for sensitive health questions.
Vivral is designed to minimize sharing, keep users in control, and make clear that AI health information is educational, not a replacement for medical care.
Privacy Policy
Nair Engineering designs Vivral for health questions that may be personal. We minimize collection, keep sharing off by default, and do not sell user data.
What users control
- Users choose what health context they add to Vivral.
- Optional product-improvement sharing is off by default.
- Users can change sharing choices in the app when available.

Information involved
Depending on how a user uses Vivral, the app may include account information, health questions, health profile details, imported documents, app settings, and payment status. Payment processing may be handled by Apple or another payment provider; Nair Engineering does not need full card details for subscription billing.
Retention
Local app data remains until the user deletes it, clears it, or removes the app. Optional improvement data, when enabled, may be retained internally to improve quality, safety, and product behavior.
