Unfortunately, there is no way for us to know which email address was used to create your Keep Secret account. This approach has been chosen to maintain the security of your data.
In order for us to find the correct email address, you will need to send us messages from EACH of the possible email addresses that you may have registered in the application. We will check everything (indicate «Is this address registered?» in the subject line of the letter). As soon as we determine which of the addresses was registered in Keep Secret, we will immediately inform you about it.
