## What is TideBook?

Most cycle apps for men show you the same textbook average. TideBook starts there — then learns from what actually happens in your relationship, and adjusts. One tap a day. Nothing leaves your phone.

HOW IT WORKS
• Enter the date her last period started — that's the whole setup
• Each day, answer one question with one tap
• TideBook blends the textbook curve with your couple's own pattern, and the forecast gets sharper every week

WHAT YOU GET
• Today's outlook at a glance, with the current phase explained in plain words
• A fourteen-day forecast strip
• The full cycle view: where she is in the month, and the best days ahead
• A next-period estimate that adapts to her actual cycle length

PRIVATE BY DESIGN
Everything stays on your phone. No account, no cloud, no analytics, no data collection of any kind.

TideBook is not a medical device and not a contraceptive method. Predictions are estimates, and cycles vary widely.
