Your audio stays on your phone.

What stays on your device

• Cough audio recordings — created, analyzed, and deleted locally.
• Screening results (label + confidence) — saved to local history if you enable it.
• Settings & preferences — theme, toggles, notification choices.

What only leaves your device if you opt in

• Screening results (label + confidence + timestamp) — synced to your account if you sign in.
• Account credentials — email + password are sent over HTTPS to Supabase Authentication.

You can sign out and delete your account at any time from the Settings screen.

What never leaves your device

• Cough audio recordings.
• Personally identifiable information beyond your email.
• Device identifiers, advertising IDs, contact lists, or location.

On-device model updates

• Lively checks a public manifest file on app launch to see if a newer screening model is available.
• If so, the new model file is downloaded over HTTPS and verified by SHA-256 before being activated.
• This is a one-way pull — the app sends nothing about you in that request.

Third-party services

• Supabase (EU / Frankfurt region) — provides authentication, encrypted database storage for results you sync, and model file hosting.
• Vercel — hosts this website. No app data passes through Vercel.
• Google Fonts — used to load the Inter and Manrope typefaces.

Your rights

• Access — view all your synced screenings in the History tab.
• Portability — export your local history as JSON from Settings (coming soon).
• Delete — remove individual results, clear all history, or delete your account.
