It helps you monitor, pace and manage your drinking\nentirely offline. It needs no invasive permissions — no camera, microphone or\nlocation — and works completely without network access.\n\nKEY FEATURES\n\n* Intelligent logging: predefine your own beverages or pick from internationally\n  common presets. Log drinks instantly or retroactively with precise timestamp\n  corrections.\n* Concurrent limit tracking: set three simultaneous boundaries — a daily limit\n  (grams of pure alcohol), a rolling 7-day weekly limit (grams), and a maximum\n  number of drinking days per week. Visual progress bars keep you informed in\n  real time.\n* Blood Alcohol Concentration (BAC) estimate: enter your body weight to get a\n  live approximation based on the established Widmark formula.\n* Counseling reports: generate a clear, well-organized two-page PDF report\n  designed for consultations and counseling appointments, summarizing your\n  habits statistically.\n* Data portability: export your full dataset as a standard CSV file for external\n  processing (e.g. in LibreOffice Calc), or create secure JSON backups to move\n  data between devices.\n* Granular adjustments: customize your \"day start\" time so late-night drinks\n  count toward the correct evening, and set custom evaluation start dates for\n  clean restarts.\n\nA comprehensive User's Guide is available inside the app.\n\nPRIVACY & SECURITY\n\nLibellus Potionis is built around absolute data sovereignty and strict data\nminimization. It runs under a minimal permission profile that completely\nexcludes network access, so your personal data never leaves the device. Your\ndata stays in the app's private storage, protected at rest by Android's device\nstorage encryption and the app sandbox. An optional biometric fingerprint lock\nguards against unauthorized physical access. This offline-first approach\neliminates tracking, cloud synchronization and external data leaks.\n\n","categories":["Sports & Health"]}
