PERIOD. Cycle & Period Tracker

About PERIOD. Cycle & Period Tracker

PERIOD. is a privacy-first lifestyle app for cycle awareness — not a medical device.

Your cycle affects everything. Energy, focus, mood, skin — but nobody teaches you how it works. Most apps overwhelm you with confusing charts, unclear predictions, and questionable data practices. PERIOD. is different.

WHAT MAKES PERIOD. DIFFERENT

- Privacy-first by design — no ads, no data selling, ever
- Built for real life — not medical jargon, just clear language
- Female-first — designed around the female body, not male health standards
- Evidence-based insights that help you understand your patterns
- Simple enough to use daily. Powerful enough to actually learn from.

WHAT YOU GET

🌅 Daily Cycle Insights
No graphs to decode — just plain language. "Today is a good day to plan, not to push." Understand what's logical for your body, today.

📊 Smart Tracking
Log only what's relevant. PERIOD. learns to recognize your patterns over time. "You've had headaches around day 21 in your last 3 cycles."

🤖 AI Assistant
Ask questions about your cycle without judgment. "Why do I feel so tired around ovulation?" Get context, not confusion.

🎓 Onboarding That Teaches
You don't just use PERIOD. — you learn to understand your own cycle. "You're now in your luteal phase — here's what that means."

🔒 Your Data Is Yours
PERIOD. does not sell your data and does not rely on invasive tracking. No advertisers. No third-party data sharing.

LIFESTYLE & WELLNESS — NOT MEDICAL ADVICE

PERIOD. is a personal wellness and lifestyle tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. If you have health concerns related to your cycle, please consult a qualified healthcare professional.
