Track chastity periods, denial streaks, unlock requests and milestones together with your partner, in one encrypted app built for keyholders and the locked.

Notes apps and generic timers weren't made for this. UNION gives keyholders and locked partners a shared, private tracker with a live timer, request logs and milestones, so the dynamic stays clear, consensual and exciting.
Start and run lock sessions with a live timer both partners can see. Track exactly how long the current period has lasted, down to the second.

The keyholder stays in control. Set session lengths, approve or extend time, and manage the dynamic from their own device.

Every lock, unlock and reset is logged automatically, giving you a transparent, private record of your chastity journey together.

Submit unlock or release requests inside the app. The keyholder can approve, deny or negotiate, with a clear log of every decision.

Celebrate denial streaks and personal bests. Milestones turn discipline into a shared game you both look forward to.

Log orgasm permissions and tie them to tasks and rewards, connecting chastity to the rest of your dynamic in one place.
