Most apps promise privacy in a policy you'll never read. Pair enforces it with math. Here's exactly how your little world stays yours — in plain language, with nothing hand-waved.
When you sign in, your password isn't sent to us. It's run through Argon2id — a deliberately slow, memory-hard function — right there on your phone, turning it into a strong encryption key that only ever exists on your devices.
From that key everything else is derived locally. Our servers only ever receive a blind verifier — a value that proves you know your password without revealing anything we could use to decrypt your data or guess it.
Every photo, video, message and note is encrypted with XChaCha20-Poly1305 on your device, before a single byte goes anywhere. What reaches our servers — and what would reach anyone who ever breached them — is indistinguishable from random noise.
It only becomes a memory again when it's decrypted on your partner's device with the key the two of you share. This is true end-to-end encryption: we are a courier carrying sealed envelopes we have no way to open.
When you invite your person, the shared key isn't emailed or stored in plaintext anywhere. It's wrapped in a sealed envelope that only their device — using their own derived key — can open.
To be certain there's no one in the middle, you can compare safety numbers: a short fingerprint that should match on both phones. If it ever changes unexpectedly, Pair tells you, so a silent key swap can't slip past you.
Forget your password and your 24-word recovery phraserestores everything. Write it down, keep it somewhere safe — it is the one and only spare key to your world.
And the honest part: lose both your password and your phrase, and even we can't get your data back. That isn't a gap — it's the guarantee. If we held a master key, so could anyone who took it from us.
Your moments aren't a product. There's no ad network in here, no analytics following you around, and nothing of yours is ever fed into a model. Pair has nothing to sell but Pair.
Even your media downloads through short-lived private links that expire — never a public URL someone could stumble onto. Privacy isn't a setting you turn on. It's the foundation everything else is built on.
