About this app

QiFlux is The Quiet Tracker — a calm, private, respectful way to track your cycle.

Open it and you see only your own records: no popups, no upsell, no ads. Logging takes seconds, your data stays on your device by default, and you can export it anytime. We believe understanding your body shouldn't cost you your peace or your privacy.

An Eastern body-constitution lens (optional)

QiFlux adds one quiet extra: a traditional Eastern perspective on "qi" and body constitution to help you read your body's rhythm. Turn on the Asia culture pack and each day shows a small, calm card describing your current cycle phase in a familiar constitution vocabulary (cold / hot / dry / damp), with optional AI reading. This is cultural and traditional reference only — it does not diagnose and is not a substitute for medical advice.

Quiet promises (every one verifiable)

• Zero ads throughout — free and paid alike
• No sign-up required; start logging anonymously
• No marketing popups (compliance notices excepted)
• On the free tier, the app doesn't reach out to send your data
• Third-party components are a public, auditable allowlist
• Cancelling a subscription is always within 2 taps
• Cloud AI is opt-in and anonymized — the paid AI plan never trains on your data

Features

• Log period, symptoms, mood and temperature in seconds
• Calendar view, auto-colored by cycle phase
• Basic cycle prediction (we don't overstate "AI")
• Health Connect integration (optional, synced through the OS)
• 6 languages: Traditional Chinese, Simplified Chinese, English, Japanese, Korean, Thai

Premium (US$24.99/year or US$3.99/month, 7-day free trial — local equivalent shown at checkout)

• 300 AI-personalized cycle readings per month (free plan: 1)
• Advanced Trends — 12 months of history + symptom-correlation heatmap
• End-to-end encrypted cloud backup (we can't decrypt it either)
• Cancel in 2 taps anytime; access continues to the end of the billing period

Privacy

QiFlux is local-first. Your period, symptom and temperature data never leave your device unless you turn on cloud backup — and then it's end-to-end encrypted on your device first. We don't sell your data, and you can export or delete it anytime. See https://qiflux.smartrich.ai/privacy

Not a medical device

QiFlux is a personal tracking tool. It does not diagnose, treat, or provide medical advice. The Asia culture pack offers cultural / traditional perspective only. For any health concern, consult a qualified professional.
