The private record, in motion

Your record. Your choice of what to share.

Move from today's cycle ring to your calendar, insights, Private Visit Brief, and privacy controls without creating an account or a trail on our servers.

Today, calendar, insights, and privacy controls. The record stays yours.

Private context for real visits

Useful today. Ready for your next conversation.

The Visit Brief turns local logs into a clear pattern summary and measures gaps honestly. Names, exact dates, notes, and intimacy details stay withheld until you switch them on.

  • 3-, 6-, and 12-month visit summaries
  • Data coverage and observed body patterns
  • Four field-by-field disclosure controls
  • An included and withheld sharing receipt
