Hi, fediverse! We're Ovumcy, a menstrual cycle tracker you run yourself. Your period dates, symptoms and fertile-window estimates stay on your own server, not in someone else's cloud. One Go binary or container, SQLite or PostgreSQL, no vendor account, no analytics, no telemetry, CSV and JSON export anytime. Open source, AGPL-3.0. Predictions are estimates, not medical advice. https://ovumcy.com https://github.com/ovumcy/ovumcy-web #introduction #selfhosted #privacy #FOSS #periodtracker
