Quick answers
Where can I see my balance and what I've spent?
Sign in to the account center. It shows your balance, every top-up and your usage broken down by product.
A task failed — was I charged?
If a task fails because of an error on our side, the usage it consumed is not charged. If you think something was billed by mistake, email us with the time and the session name and we'll look into it.
How do I delete my data?
On iPhone, go to Settings → Delete account to delete your Duck Do data. Data from Mac sessions lives on your Mac; you can remove it in Settings → Privacy → Clean up storage, or by deleting the app's data folder. See the Privacy Policy for what we keep and why.
I can't sign in after reinstalling.
Sign-in tokens are stored per device in the system's secure storage, so a reinstall needs a fresh sign-in. Use the same email or Google account as before; your cloud chats, memory and balance are tied to your account, not the device.
