NHOS operates on a Privacy-by-Design, client-side model. All personal metrics, health tracking logs, and application preferences remain stored strictly within your local browser storage (IndexedDB/Local Vault). Nothing is stored in the cloud, and zero data is ever transmitted to external servers or third parties. Your data stays on your device. Always.
Your local vault is protected using client-side AES-256-GCM encryption derived from your personal passphrase. Because NHOS holds zero master keys, recovery passwords, or remote backups:
Lost passphrase = unrecoverable data. NHOS does not store recovery keys or passwords. You maintain 100% ownership and control of your health vault.
Why can't NHOS recover my data? — Your information is encrypted locally using your personal passphrase. This protects your privacy but means a lost or forgotten passphrase cannot be restored. This is by design: Your health data belongs to you — not to any platform.
Because NHOS does not collect, process, or transmit personal data to remote infrastructure, traditional server-side data retention and third-party processing under Article 6(1)(a) GDPR do not apply. You hold absolute rights to inspect, export, or immediately erase your data locally at any time by clearing your browser storage. Who owns your health data? You do.

Your data is stored exclusively on your local device. Because NHOS does not maintain central servers, we store zero user data. Data retention: Your health metrics and application settings remain on your device for as long as you choose. Your rights: You hold total sovereignty over your records. You may audit, export, or purge your local database instantly through the application interface or by clearing your browser cache.
