How Febra works

Frequently asked

Where is my data stored?

In a single file inside the app on your device. See the privacy policy.

Do I need an account?

No. There is no sign-in and no server. Febra works entirely on your device, even in Airplane Mode.

Can I sync between two iPhones?

No. Febra is deliberately local-only; there is no server to sync through.

How do I move my data to a new iPhone?

Restore the new device from your iCloud or computer backup — the app's data comes along with it. There is no separate export/import yet.

Can I connect a Bluetooth thermometer?

No. Every measurement is typed in by hand — a deliberate choice that keeps the app free of pairing, permissions and background access.

How do I switch the language?

iOS Settings → Febra → Language, or use the Language row in the app's Settings screen, which takes you there.

What do the fever thresholds mean?

They follow the age of each family member at the time of the reading. Add a date of birth to a member to get the age-appropriate bounds; without one, adult bounds are used.

Is the “next dose” a dosing recommendation?

No. It is a reminder based on a minimum interval you set yourself. Febra makes no medical recommendations and does not replace seeing a doctor.

How do I export a history for the doctor?

Open a member's history and export it as a PDF — chart, table and thresholds included. iOS's share sheet lets you decide where the PDF goes.

Privacy

Febra collects nothing and makes no network requests. Details are in the privacy policy.

Febra is no substitute for medical advice and makes no diagnosis. With a high or persistent fever, please consult a doctor.
