MoonVault is a privacy-first period diary designed for calm, local cycle tracking. No account is required. There are no ads. There is no third-party tracking. Your basic tracking stays on your device by default, and optional cloud backup can be turned on for your account when you want it. With MoonVault you can: - Log period start and end dates. - Track flow level, symptoms, mood, and private notes. - See logged and estimated days on a clean calendar. - Follow local insights such as average cycle and period length. - Receive gentle morning, noon, and evening support messages. - Use safe self-care cards without exposing sensitive details. MoonVault does not provide medical advice, diagnosis, treatment, contraception, or fertility guarantees. Predictions are estimates based on the information you enter. For health decisions, consult a qualified healthcare professional. YOUR DAILY RECORD, AT YOUR PACE - Mark today as a period start or edit earlier entries. - Record light, medium, or heavy flow. - Select cramps, headache, bloating, fatigue, nausea, cravings, and other symptoms. - Add your mood and a private journal note in a few taps. CALENDAR AND ON-DEVICE ESTIMATES See logged period days and upcoming estimated days in distinct calendar styles. With enough history, MoonVault calculates average cycle and period length on your device. Until then, it uses the usual lengths you choose in settings. Future dates are always labeled as estimates and are never presented as contraception or fertility guarantees. CARE FOR BODY AND MOOD TOGETHER Gentle wellness messages, your chosen guide character, and optional morning, midday, and evening reminders create small moments of support. Notification wording avoids revealing explicit cycle details on the lock screen. Self-care cards never include exact dates or private journal content. PRIVACY YOU CONTROL MoonVault does not require an email address, phone number, or profile to start. Basic tracking stays on your device by default. If you want, you can turn on optional cloud backup for your account, then restore or delete that backup later. Delete all local data at any time from settings. On supported devices, app lock and Face ID add another layer of protection. Deleting the app may also delete local data if it has not been backed up separately. FREE CORE TRACKING, OPTIONAL PLUS Period logging, calendar, mood, symptoms, and basic estimates remain available. MoonVault Plus adds more themes, personalization, guide choices, and reminder controls without blocking the essential cycle diary.
