First, try this.
Quick checks that fix most hiccups without touching your memories.
I can’t see something my partner sent me
Check your connection, reopen Duonook, and give it a few seconds to sync. If your device asks to be authorized again, complete that step first.
Notifications aren’t arriving
Open Profile → Settings → Notifications and check which categories are turned on. Then make sure Duonook has permission to send notifications in your phone’s settings.
An invite won’t open
Open the link on the phone where Duonook is installed and make sure you are using the latest version of the app. Each invite is valid for 7 days: if it has expired, ask the person who invited you for a new one. Invites are private: avoid sharing them anywhere public.
I got a new phone: how do I recover my Couple?
Open Duonook on your new phone and, on the first screen, choose “Recover my Couple.” You can paste your personal key or scan its QR code. When you are done, save the new key: the one you used for recovery is replaced.
I want to keep a copy of my data
In Profile → Settings, you’ll find “Export a copy.” Duonook prepares a readable JSON file with the information stored on your device and opens the system share sheet.
I need one-on-one help
Write to support@duonook.com. Don’t include letters, gift messages, recovery codes, or other private content in your request.
Asking for help safely
Describe the problem, not the content.
To diagnose an error, all we need is the app version, the device model, and the step where things stopped. Support does not need to read what you have written in Duonook.
Never share
Access codes, recovery keys, invite links that are still valid, letters, gift messages, photos, or screenshots showing intimate information. Your partner must use their own key too.
