FIRST PERIOD GUIDE New to periods? Open the Guide tab from Calendar or Settings. Plain language, no jargon. Written for anyone at the beginning. AsterKit is a personal wellness app for tracking your cycle. Not a medical device. A private place to log your period and understand your own patterns. THE DIFFERENCE Most period apps track every tap, bundle analytics SDKs, and sell your cycle data to advertisers. AsterKit does none of that. Cycle data stays on your device, protected by the operating system. We have no servers, no database, no copy of your history. HOW IT WORKS A parent completes a quick math check (about 10 seconds) to get started. No PIN, no account. Then the 7-day free trial starts. After day 7, a one-time $4.99 purchase unlocks everything. No subscription, no recurring charges. WHAT YOU CAN DO LOG YOUR PERIOD Record start and end dates. Add intensity (light, medium, heavy, spotting), symptoms, and mood. All stored locally on your device. GENTLE PREDICTIONS After 3+ cycles, see an estimated date for your next period. Based on your personal history. Predictions are estimates only; everyone's cycle is different. ADVANCED INSIGHTS (Premium) Average cycle length, period duration, and consistency patterns. Export a PDF summary to bring to a doctor's appointment. PRIVACY, PLAINLY • Cycle data stays on your device. • We have no servers, no copy of your history. • The only thing that ever leaves your phone: an anonymous receipt token (it confirms your purchase is valid). That's it. • No analytics. No ads. No data sharing. ONE PRICE. YOURS TO KEEP. 7-day free trial, then one-time $4.99. No subscription, no recurring charges, no surprise bills. NOT MEDICAL ADVICE: AsterKit is not a medical device and should not replace professional medical advice. For medical questions about your cycle, consult a healthcare provider.
