Encrypted sync

Conversation sync keeps every device on the same page: close the laptop, pick up the conversation on your phone. Everything is encrypted on your device before it leaves. Olace cannot read your conversations.

How it works

Your devices share a master key that never reaches Olace in usable form. Olace's servers store only wrapped keys and ciphertext. Encrypted sync is available on paid plans; see Plans & credits.

Set it up

When you enable sync, Olace asks you to:

1. Save your Recovery Key. Shown once. Usually you will unlock with your PIN or a trusted device; the Recovery Key is the fallback if you lose both. Save it somewhere safe.
2. Set a Sync PIN (optional). A 6-digit PIN that unlocks your synced chats on new devices. Skip it and new devices unlock with a trusted device or your Recovery Key.

You can skip this and finish it later under Settings › Conversation Sync; nothing syncs until you do.

Unlock a new device

A new device offers three ways in, and you can always pick Try another way:

• PIN. Enter your 6-digit Sync PIN, if you set one.
• Trusted device. Approve from a device that already has your key, then tap the number this device shows on that device to confirm it is really you.
• Recovery Key. Enter the key you saved during setup.

On the web

In the web app your key stays in memory for the browser session. When the session ends, unlock again. To stay unlocked on a browser you own, choose Trust this browser: the key is then kept in that browser, wrapped under a key the browser cannot export. Skip it on a shared computer. Conversations are kept encrypted in the browser database the whole time.

If your plan lapses

Sync pauses rather than disappearing: your encrypted cloud copy is kept for 60 days, and resuming a paid plan within that time picks up where it left off. After 60 days the cloud copy is deleted. The conversations on your devices stay where they are.
