Chastikey is a private accountability companion for adults who practice consensual keyholding and self-discipline as part of their lifestyle. Set a lock, choose how it ends — a fixed timer, a random window, a secret combination, or a card game of chance — and let the structure keep you to your word. Hand the key to a partner you trust, or let an AI keyholder hold it for you: a dominant, attentive companion who remembers your rules and keeps you accountable. • Lock your way — timer, random, combination, or card-game release • An AI keyholder with distinct personalities — firm, playful, strict • Works with Lovense connected devices — paired over Bluetooth, driven only within the limits you set • Live Activity & Dynamic Island countdown • Decks, rituals, stats and a private archive of your history • Optional partner keyholding • Works with Apple Health — habits can be filled in from your steps, exercise minutes and Activity rings (read-only, with your permission) Chastikey is about control, patience, rules and follow-through — not explicit content.
