About this app
Bound is a private couples journal for two people who want a quiet place to be honest with each other. Not a chat app. Not a social timeline. A sanctuary, kept between you.
A PRIVATE COUPLES JOURNAL
A shared, private journal where the two of you write to each other — small notes, longer reflections, the ordinary weather of a week. Bound is a relationship journal for couples who prefer attention over performance, and a couples journal built for two rather than for an audience.
END-TO-END ENCRYPTED
Built on NaCl. Encrypted on your device before anything leaves it. Only the two of you can read what's inside — not us, not anyone.
No ads. No tracking. No data selling. Ever.
A COUPLES CHECK-IN APP, USED QUIETLY
At the heart of Bound is a daily check-in — a short, private way to share how you are without asking your partner to interpret silence. As a couples check-in app, Bound stays out of the way. Notifications fire only when your partner does something, never to push you back in.
PATTERNS, NOT PROMPTS
After a few weeks of writing in Bound, you'll start to see real patterns in your relationship over time. Not generic advice. Not AI guesses. Just clear, private observations from your own shared history — the quiet signal underneath the noise of a week, the weather of a month, the through-line of a year.
SOLO MODE
Bound works for one person before the other joins. Use it on your own as a private journal — for personal reflection and to notice your own weather. Everything you write stays encrypted, kept for you, until you choose to share it.
FOR COUPLES WHO —
Are dating, long-distance, married, or building something serious. Want a quiet, private place to keep a couples journal with grace. Care more about the texture of an ordinary day than the milestones.
Start free for 7 days. Then $7.99 per month.
Premium unlocks extended history and longer-term pattern views.
