Onni does not collect or transmit any personal data. Everything you enter — symptoms, medications, vitals, the names of people you track, and any photos you attach to a symptom — is stored only on your device. The app requires no account, contains no analytics or advertising, and never sends your information to us or to any third party.
If you use iCloud Backup or back your phone up to a computer, your device may include Onni's data in those backups. Backups are controlled by you and processed under Apple's terms; we have no access to them.
Photos you attach are saved within Onni on your device only — they are never added to your photo library or sent anywhere. If you export a PDF, any attached photos are included in that file, so share exports only with people you trust.
If you choose to export your data (for example as a CSV or PDF file), the export happens directly from your device. Anything you then share by email, messaging, or other apps is handled under those services' own privacy policies.
Onni is often used to record information about family members, including children. That information remains on your device like everything else, and you are responsible for the records you keep about others.
If this policy ever changes, the updated version will be shown here with a new date.

Onni is designed for personal record keeping only. It does not diagnose conditions, interpret your records, or recommend treatments, and it is not a medical device. Reports and exports are for informational purposes and should not be considered medical advice.
Records are only as accurate as the information entered, including readings taken from your own measuring devices. Always verify important information before relying on it.
Please consult your doctor or healthcare professional about any health concerns. If you think you may be experiencing a medical emergency, do not rely on this app — call your doctor or emergency services immediately.
