Dear Snap Data Protection Officer,
I am writing to exercise my right to erasure under Article 17 of the GDPR in relation to two Snapchat accounts that belong to me:
alexemmet
alex_emmet
I previously contacted Snapchat Support through X, formerly Twitter, because I was unable to identify a functioning general support email address or reach a human support representative through the available support channels.
In my message through X, I explained that I am requesting deletion of both accounts and the personal data associated with them.
I still have access to the login credentials for alexemmet and can verify ownership of that account through the normal account-access process.
For alex_emmet, I no longer have access to the old device, email address, or phone number that may have been associated with the account. The account was created when I was under 18.
Snapchat Support responded through X that it could not take action where a user does not know, or no longer has access to, the email address or phone number associated with an account.
I would like to clarify that I am not requesting account recovery, a password reset, or restored access to alex_emmet. I am making a data-subject request for erasure of my personal data.
I understand that Snap is entitled to verify my identity before acting on this request. Under Article 12(6) GDPR, where there are reasonable doubts concerning the identity of the person making a request, the controller may request additional information necessary to confirm the person's identity.
I am therefore asking Snap to provide an alternative means of verifying that I am the data subject associated with alex_emmet, given that I no longer have access to the original device, email address, or phone number. I am willing to provide reasonable information necessary for verification through a secure channel.
My request covers:
deletion of the Snapchat account alexemmet;
deletion of the Snapchat account alex_emmet;
erasure of personal data associated with both accounts;
erasure of personal data contained in previous support correspondence, support tickets, attachments, account-recovery records, and associated metadata concerning me.
If Snap considers that any of this data must be retained, please identify the categories of data being retained, the legal basis for retention, and the applicable retention period.
If Snap considers that it cannot comply with the erasure request for alex_emmet, please provide the specific reason for that decision and explain why no alternative method of verifying my identity is available.
I would also appreciate confirmation that this request is being handled as a GDPR data-subject request rather than as an account-recovery request.
I can provide screenshots of my correspondence with Snapchat Support through X if required.
Kind regards,
Alex

# Omega
The Omega is Tensamin's central Server. It maintains the centralized user Registry & manages Omikron useage.
On first start Omega creates an unencrypted private keyring at `./omega.mk` and the matching public bundle at `./omega.mpkb`. Existing identity files are loaded fail-closed, so a malformed keyring or mismatched public bundle stops startup. A missing public bundle is rebuilt from a valid private keyring without generating a new identity.
## MTP routing contract
Omega preserves the MTP distinction between an absent routing field and a
present zero value on the wire. For Omega request and response operations,
both forms are rejected:
- request IDs are required and nonzero for correlation;
- authenticated sender and receiver IDs are required and nonzero;
- fields that are optional for a particular notification remain `Option` and
are not converted to zero.
