To serve you with appropriate discretion, TOM requires a few pertinent details. Everything remains on your device. Naturally.
"This app offers guidance based on typical hormonal patterns. Human beings remain gloriously unpredictable. TOM is a helpful guide, not an exact science."
Ask TOM whether a topic is safe to raise, or put a worry to him. He handles concerns, questions, and tactical dilemmas with equal discretion.
Record how the day went. TOM will track patterns over time and advise accordingly.
Log each time a period begins. TOM will use your history to refine the cycle length prediction over time.
