How can we help?

Support, payments, privacy requests and security reports. First reply target: 2 hours; maximum 48 hours.

Response target: we aim to send a first reply within 2 hours. We allow up to 48 hours when volume is high, on weekends or holidays, or when we need to verify account control.

Include your username and, for payment issues, the NOWPayments invoice or payment ID. Never send passwords, private keys, seed phrases or authenticator codes.

Support response SLA

Target first response: within 2 hours during normal operations.
Maximum: up to 48 hours when volume is high, on weekends or holidays, or when account verification is required.
Security reports and suspected account compromise: prioritized. Put SECURITY in the subject line.
Response times are measured from when your email reaches [email protected]. An automated acknowledgement is not a human response.
This is an operational target, not a contractual guarantee.

Account and sign-in help

Lost your authenticator? Use a recovery code on the login screen. If you have none, email us from an address you can access and include your username.
Username changes are available with Premium or Staff and limited to once every 30 days.
Deleting your account is permanent and removes your messages, files and sessions. We cannot restore a deleted account.

Payments

Premium is paid in crypto through NOWPayments. Purchases are non-refundable.
If a payment left your wallet but Premium did not activate, send us the invoice ID and payment ID. Do not send wallet private keys or seed phrases.
Dashboard-created payment links are not linked to an account and do not activate Premium.

Privacy and data requests

For access, deletion or other privacy requests, email [email protected]. Because Markero does not require an email address, we may need to verify that you control the account. See our Privacy Policy for details.

Security reports

Please report vulnerabilities privately to [email protected] before public disclosure. See the security page for the threat model and scope.
