Withdraw pending research interest
Enter the private code from your registration receipt. A valid receipt code removes the pending email record and its private references. This request sends no email. Public worksheets remain available.
Use your private receipt
The code is submitted in the form body and never added to the address bar. Keep it private. The response does not reveal whether a code matched a pending record, had expired or was already used.
If you no longer have the receipt code, self-service withdrawal cannot identify the record. Pending interest expires after 30 days. Physical deletion follows the scheduled cleanup. See the privacy policy for details.
