Jaci was built around one rule: your health data belongs to you, and only you. This policy explains, plainly, what the app stores and what it never does.
Your name, health profile (menopause stage, last period date, cycle length, HRT, lifestyle habits) and every symptom you log are stored in a local database on your phone. There is no account to create and no server that receives this information — Jaci has no backend at all.
Only what you choose to enter: your name, optional email and birth date, your health profile, and your daily symptom logs. We don't collect device identifiers, location, or any data you haven't typed in yourself.
Notifications, to schedule your daily reminder locally on your device. Camera and Photos, only if you choose to set a profile picture — the image is processed and stored on your device and never uploaded anywhere.
Only when you choose to export or back up your data — for example, sharing a clinical report with your doctor, or saving a backup file. Every export shows a confirmation step first, and you decide where the file goes (email, messaging app, cloud drive). Jaci has no server to send it to even if it wanted to.
No analytics or tracking SDKs, no advertising, no selling or sharing data with third parties, and no cloud sync you haven't explicitly initiated yourself.
You can erase everything from inside the app at any time, or simply uninstall it — since all data lives only on your device, nothing remains anywhere else.
Jaci is designed for adults navigating perimenopause and menopause, and is not directed at children.
If this policy changes, the update will ship inside the app with a new date above. Continued use after an update means you accept the revised policy.
