Update your email address

Your email is your sign-in identity. Changing it is intentionally a two-step verification flow — both addresses confirm before the swap takes effect.

Steps

1. Go to Settings → Profile (https://ritsu.ai/settings/profile).
2. Next to Email, click Change.
3. Enter the new email. Click Send verification.
4. We send two emails:
   • To the new address: a confirmation link to prove you own it
   • To the old address: a heads-up plus a "this wasn't me" link in case the change is unauthorised
5. Open the new-address email and click the link. The swap takes effect immediately.
6. You stay logged in on the device you initiated the change from. Other devices may need to re-authenticate.

What changes when email changes

• Sign-in: only the new address works going forward
• Receipts and billing emails go to the new address
• Outbound notifications (digests, security alerts) go to the new address
• The old address is kept on file for 30 days as a fallback for "this wasn't me" recovery, then deleted

What does NOT change

• Your account ID, your data, your subscription
• Saved decks, quiz history, learning progress
• API tokens (if you have any)

OAuth accounts

If you signed up with Google / Apple / Microsoft, your email is managed by that provider. Changing it inside Ritsu disconnects the OAuth link — you'll be prompted to set a Ritsu password before the swap finishes.

Trouble

• Verification email not arriving — check spam, and verify the new address is correct.
• "Email already in use" — that address is on a different Ritsu account. You can't have two accounts on the same email.
• Old email already gone — contact support@ritsu.ai with proof of identity (last billing receipt, account ID).
