FAQ

How this task behaves.

  • 01

    Can the AI predict my exact ovulation day?

    No. The AI provides a window and peak days based on mathematical probability from your data, not a guaranteed single day.

  • 02

    Does the AI change my original cycle logs?

    No. The AI only reads your data to perform calculations. It cannot edit, delete, or modify your existing logs.

  • 03

    Can I use this to track pregnancy?

    No. This tool is designed to calculate fertile windows and peak days for conception, not to monitor pregnancy progress.

  • 04

    What happens if my cycle is irregular?

    The AI uses the data you provide. If your cycles vary, the window will reflect the patterns found in your history.

  • 05

    Can the AI suggest medical treatments?

    No. The AI is a calculation tool. It does not provide medical diagnoses or treatment recommendations.
