The Ritual
Each day, a sealed envelope arrives. Inside lies your partner's desires — carefully curated moments waiting to unfold.
Schedule intimate encounters. Align on activities. Surrender to what your dominant has prepared — or whisper your own desires.
Time becomes sacred. Anticipation, a pleasure of its own.
Core Experience
Devotion Made Visible
Track obedience and mischief with elegant precision. Visual gauges display your Obedient vs. Naughty scores. Every streak unlocks treasures; every slip carries consequence. Habits become visible, gems await the devoted.
Curated Looks
Let your partner gaze upon your collection. Allow them to curate your look — what you wear becomes their desire. Share your wardrobe, receive outfit requests, and dress for their pleasure.
Elegant Denial
Track periods of denial with sophistication and grace. Set durations, log progress, and watch your devotion unfold. Special rewards await those who maintain discipline — each milestone celebrated, each moment of control honored.
Private & Shared Reflections
Capture your thoughts privately or share them with your partner. Journal your moods, fantasies, and desires in a dedicated space. Use mood and energy check-ins to stay emotionally aligned — understand each other without always needing words.
Mandatory Moments
A dedicated screen for daily obligations. Log completion of assigned tasks — sending outfit photos, daily messages, or specific rituals. Each completion builds your score and demonstrates devotion.
Daily Delivery of Desire
Every day begins with anticipation. A luxury digital envelope arrives, sealed with your partner's intentions. Inside: curated tasks, time-bound moments, and controlled unpredictability. Open it to discover what awaits — or keep it sealed, savoring the suspense.
Structured Intimacy
Transform spontaneous moments into deliberate rituals. Schedule intimate encounters, align on activities, and build a shared calendar of desire. Your dominant prepares; you receive. Or submit your own requests through an elegant interface.
Gamified Connection
Behavior becomes measurable. Your devotion translates to credits, unlocking exclusive experiences and rewards. Maintain your streaks to access Sensory Journeys — curated experiences that deepen your bond.
Curated Inventory
A gallery of high-end equipment and sensory items. Not mere objects — but instruments of experience. From the Empress Bench to Silk Restraints, manage your collection and begin curated play sessions with a single touch.
Earned Luxury
A credit-based marketplace where devotion transforms into luxury. Redeem earned points for experiences: Sensory Showers, Seduction Evenings, or whatever your partner has placed on the menu. Good behavior has its privileges.
Glanceable Intimacy
Stay connected without opening the app. Home screen widgets keep your dynamic visible — see your Brat Pass status, upcoming tasks, open punishments, scheduled rituals, and your chastity or orgasm counter at a glance. Your devotion, always present.

Everything you want to know about the UNION kink & BDSM app.
UNION is a private app for couples who share a D/s dynamic. It brings tasks, rules, rewards, punishments, a shared journal, chastity tracking, check-ins and more into one encrypted space, so your BDSM relationship has structure and rhythm without spreadsheets or scattered chat messages.
No. UNION works for complete beginners exploring kink for the first time as well as established Dominants and submissives. You decide which features you turn on, so you can start with simple daily tasks and grow into deeper protocol and control dynamics at your own pace.
Privacy is the foundation of the app. Sensitive partner content is end-to-end encrypted, you can use a pseudonymous identity, and there is an anonymous login so you can start without an email address. Your kink life stays between you and your partner.
Yes. The shared environment, schedule, verification hub and check-ins keep both partners aligned no matter the distance. Many couples use UNION specifically to maintain a consistent dynamic when they cannot be in the same room.
It does. The optional lock and timer system lets both partners track sessions, while unlock requests and logs create a transparent history. It is built for clear, consensual control rather than guesswork.
UNION is arriving on iOS and Android. Early adopters who Join the Newsletter get access first plus a launch offer. You can explore the core experience and decide what fits your dynamic before committing.
Yes. We built a free BDSM test that maps your dominant, submissive, switch, and fetish tendencies into a detailed kink personality profile — no signup required. It is a perfect starting point before you bring your dynamic into the UNION app.
Try our free kink quiz. It challenges your understanding of consent, safety, and communication, then highlights your strengths and areas to grow as a practitioner. It pairs well with the BDSM test for a complete picture of who you are.
