Everything about your account is under Settings. This page covers the everyday parts; security has its own page, as do notifications and billing.
Public or private
The single most useful distinction, because it is the one people get wrong:
| Public — anyone can see | Private — only you |
|---|---|
| Username | Email address |
| Display name | Payment details |
| Profile picture | Your library |
| Profile description | Your prompts |
Display name and username
Your display name is what people read. Change it freely; nothing breaks.
Your username identifies you. Some names are reserved and will be refused.
Profile picture
Upload one from your settings.
Email address
Used for signing in, for account notices, for resetting your password, and for receipts.
Changing it requires confirming the new address — a link is sent there. Until you follow it, the old address remains in use. That is the point: an unconfirmed address might be a typo, and an account whose email nobody can read is an account nobody can recover.
Keep it current. If you lose access to the address on the account, getting back in becomes considerably harder.
Sign-in methods
Shows how you sign in — an email and password, or a connected account such as Google — and which you used last.
Worth checking if signing in is not working. Trying a password on an account that only ever had Google fails simply because there is no password on it to match.
Language and appearance
Light and dark theme, and similar display preferences. These are yours and follow your account rather than the device, so the app looks the same on your phone as on your computer.
Developer API
A tab for people who want to drive the product from their own code rather than the app. You request access, and once granted you manage API keys there — each listed by its prefix and status, with revoke available.
Nothing about it affects ordinary use, and you can ignore the tab entirely if you are not writing software against it.
Connected sessions
Where you are currently signed in, and where you can sign out of a device you no longer have. This lives with the security settings; see keeping your account secure.
Closing the account
Under danger zone, deliberately separated from everything else and behind a confirmation. See deleting your account.
Note that cancelling a plan and deleting an account are different things. Cancelling drops you to the free plan and keeps everything. Deleting removes it.
