The encrypted couples app we can't read either.
Pair is a secure, private app for couples where everything is end-to-end encrypted on your device before it leaves it. Not hackers, not advertisers, not even us can open your shared world. That's not a policy — it's the architecture.
True end-to-end encryption, on everything.
Every photo, message, album and note is sealed with XChaCha20-Poly1305 on your device before upload. What sits on our servers is ciphertext — unreadable without the key only you and your partner hold.
It's not just your messages that are protected, the way one feature might be in a bigger app. In Pair, your entire shared world is encrypted the same way.
- XChaCha20-Poly1305 on every item
- Keys derived on-device with Argon2id
- The server only ever sees a blind verifier
- Locked albums for your most private moments
Zero-knowledge by design.
Your password never leaves your device. It's turned into your encryption key locally, so we never see it and never can. We hold no key, so we can decrypt nothing.
If Pair were breached tomorrow, the attacker would walk away with noise. Privacy you have to trust isn't privacy — this is privacy you can verify.
Recoverable for you, no one else.
A 24-word recovery phrase means a forgotten password never locks you out. Keep the phrase safe and your shared world is always restorable.
Lose both your password and your phrase, and even we can't get in. That's the honest cost of an app that genuinely can't read your data — and we wouldn't build it any other way.
Questions, answered.
An encrypted couples app keeps everything two people share — photos, messages, albums, notes — readable only by the two of them. Pair uses end-to-end encryption: content is sealed on your device with a key only you and your partner hold, so the company running the app (and anyone who breaches it) sees nothing but scrambled data.
Yes. Every photo, message and note is encrypted on your device with XChaCha20-Poly1305 before upload. Your password never leaves your device — it's turned into a key locally using Argon2id, and the server only ever holds ciphertext. This is the same class of encryption used by serious secure-messaging tools, applied to your whole shared world.
No. Pair is zero-knowledge by design. We never receive your encryption key, so we can't decrypt anything you store. If our servers were breached, an attacker would get meaningless noise.
When you set up Pair you get a 24-word recovery phrase. If you forget your password, that phrase restores access to everything. If you lose both your password and your phrase, not even we can recover your data — that's the trade-off true zero-knowledge encryption requires, and it's deliberate.
Yes. Locked albums stay hidden from the main library behind their own gate, and because everything is end-to-end encrypted, your private photos are never visible to us, to advertisers, or to anyone scanning content. It's a private photo vault built for two.
