Luma: Private Period Diary

Luma is a simple, private period and symptom diary for adults. Record what happened, keep your history together, and choose what to share. QUICK DAILY LOGGING Record bleeding, spotting, period starts, pain, mood, symptoms and daily impact. Add an optional note. Choose your favorite symptoms for faster logging. YOUR HISTORY, AS YOU RECORDED IT Tap a calendar day to add or edit an entry. See observed intervals between recorded period starts, including long gaps. Unlogged days stay unknown. Luma does not predict your next period, ovulation or fertile days. REPORTS YOU CONTROL Save a PDF or CSV for a date range you choose. Personal notes are excluded by default. Preview your records before exporting and share a PDF using your phone's share menu. PRIVATE BY DESIGN Your diary is encrypted on your device. No account or subscription. Your diary works offline. Luma contains a banner in Settings and occasional interstitial ads after viewing reports. Ads use internet access and advertising-related device data; diary records are never supplied to advertisers. Available ad privacy choices can be reviewed in Settings. An optional device screen lock protects returning to the app. Optional reminders use discreet wording without health details. BACK UP YOUR DIARY Save an encrypted, password-protected backup to a location you choose. Review dates and conflicts before importing. Luma also imports its own CSV format; other apps' exports need conversion first. Keep your backup password safe: it cannot be recovered. Uninstalling the app or losing your phone can lose your diary without a separate backup. MADE FOR EVERYDAY USE Four clear screens, system dark mode, scalable text and layouts for phones and tablets. English interface. Android 8.0 or later. Luma is a diary, not a medical device. It does not diagnose, treat, cure or prevent any medical condition and is not a contraceptive method. Consult a qualified healthcare professional about symptoms that concern you. PDF and CSV exports are readable by recipients. Only share with people and apps you trust. Reminder delivery is approximate and depends on your device settings.
