A journal that stays a journal
Feelings, therapy notes, drafts of hard conversations. Written honestly, because nobody else will ever read them.
Use case
Private and partnered — both at once.
Being close to someone doesn’t mean every photo, note and thought stops being yours. Sealby gives you a private space on your own phone, for the journal, the surprise, the past. No shared moment, borrowed phone or glance over your shoulder can open it.
Is it okay to keep some things private in a relationship?
Yes. Healthy relationships run on trust, not total transparency. A private journal, a therapist’s worksheet, a gift you are planning, photos from a life before. Keeping them to yourself is dignity, not deception. Sealby holds that private space in an encrypted vault only you can open, so it never has to become a conversation.
Surprises that survive
Gift ideas, ring photos, party plans. Out of sight even when your partner uses your phone for the map or the playlist.
Your past stays yours
Photos and letters from a life before this relationship don’t need deleting. They don’t need explaining either.
Early days, your pace
New relationships are private by default. Keep leftovers from dating apps, chats and photos sealed until you decide what anything means.
Privacy and honesty aren’t opposites. This page is about the first, and assumes the second. If your situation is about safety rather than space, the domestic-safety guide above is written for it.
Common questions
Isn’t a hidden vault just for hiding something bad?
A lock on a diary never meant the diary was guilty. Privacy inside a relationship protects the same things it protects everywhere else: your inner life, your surprises, your history. Tools don’t make choices, people do. Sealby is built for dignity, not deception.
What if we share a phone or iPad?
That’s exactly the design. Every PIN opens its own vault, and there is no list or count of vaults anywhere. On a truly shared device, each person’s private space stays private. No profiles, no visible app lock, no arguments about what’s “hidden.”
What if I’m asked to unlock it?
A PIN you share opens the vault you choose to show: a normal, believable one. Whatever you haven’t shared stays locked, and nothing in the app points to it. If going through your phone is a pattern rather than a moment, our domestic-safety guide covers that harder situation.
