Half a minute
See it in use.
The home screen, the ring that counts your time in chastity, an entry logged in two taps, a relationship with its check-in, the board and the sharing switches — and the colour themes at the end.
No sound. Everything you see is sample data.
At a glance
What matters now.
The home screen shows how long the current chastity period has run and how far it is from your goal, how long it has been since your last orgasm, your longest streak, your total time in chastity, and your edges over the past week.
Everything you record gathers in a history you can filter by day, with statistics on how your orgasms fall across outcomes.
Fast to log
Seconds, not minutes.
Logging is built for the moment, not the desk: pick the kind, choose the type, save. Everything else — permission, intensity, satisfaction, time, a note — is on the same screen, already filled in, and you can leave it alone.
- Chastity periods, with an optional goal and the device you use
- Arousal, with level, erection and frustration
- Edges, counted per session rather than one by one
- Orgasms, with type (full, ruined or dry), whether it was permitted, intensity and satisfaction
Not everyone is in it for the same thing. Chastity, orgasms, edges and arousal can each be switched off, and they then disappear. What you have already recorded stays.
Together, if you want to
One of you leads. Both of you are heard.
You can share data with up to five people. In each relationship one of you is the Dom and the other the Sub — so you can be one thing to one person and the other to someone else. If you just want to show each other what you share, you both choose View: no check-ins, flags or board.
Once paired, either of you can send a traffic-light check-in with one tap, and either of you can raise a “talk to me” flag with a short heading of your own. The conversation itself happens between the two of you. And the Dom keeps a board of rewards and penalties that the Sub can see — two separate tallies, never netted off against each other.
Pairing means exchanging codes: scan each other's screen when you are together, or send each other the codes, and confirm with one tap that you see the same six-digit number. There is no user search and no directory, so nobody reaches you unless you gave them a code yourself.
Sharing
You decide what they see.
Sharing your journal is off when a relationship begins, and stays off until you turn it on — separately for each person and each kind of entry. Your chastity periods, your orgasms, your edges, your arousal and the notes you write about them are separate decisions, not one.
What travels between two people is encrypted with a key only your two phones can compute, and signed, so nobody can read it or slip anything in. We cannot read it either.
You can block a partner at any time: the relationship and the keys are gone immediately, pairing with them again is refused, and they are not told.
Private by design
We keep no copy of your journal. That is the point.
DDiary is built on one idea: this is yours first. Your journal stays on your phone unless you decide otherwise. Syncing to your own devices runs through your own iCloud. Sharing with a partner travels encrypted through our Mailbox, which cannot read it.
- No account No sign-up. We only get your email address if you enter it yourself. There is nothing to log in to.
- Local by default Sync through your own iCloud is off until you switch it on.
- Nothing watching No analytics, no tracking, no advertising, no third-party components.
- Your words, your key Notes and the other things you write in your journal are encrypted with a key that stays in your own Keychain.
- Locked when you leave Optional Face ID or Touch ID, applied every time the app has been in the background.
- Gone when you say so Delete your journal permanently, at any time. Here's how.
Two things worth knowing before you start.
Because we keep no copy of your journal, we cannot restore it for you. Left local, your journal is gone if you delete the app — so keep an encrypted device backup. Turn sync on and it follows you to your next phone instead.
And what has already been shared cannot be recalled. Switching a kind of entry off stops what comes next; it does not reach into someone else's phone.
Appearance
Make it look like yours.
Four colour themes — Ember, Bordeaux, Midnight and Sage — each in a light and a dark form. Follow your phone's setting or choose for yourself.
The choice stays on the device. It is never synced and never shared.
Yours first. Shared by choice.
