Terms & privacy
Updated 14 November 2026. Operated by RENDUN LIMITED. Contact: support@rendun.co (include “661m” and your account email).
Your allocation
$2.99 USD purchases one subdomain allocation for 365 days, including managed DNS and scoped API access. This is a license to use a name under 661m.com, not an independently registered domain. There is no automatic renewal or recurring debit. You can renew in the console. Each domain supports up to 100 DNS record values. Hosting, mailboxes, HTTP redirects, certificates, search indexing and third-party acceptance are not included.
Early access
The service currently runs on one server. The two advertised nameservers share that server and do not provide independent redundancy. No uptime SLA is offered. Provider integrations and internet DNS caches can delay activation. We preserve your order and retry provisioning; do not pay again if provisioning is pending.
Expiry and acceptable use
The console shows your expiry date. After the paid term there is a seven-day renewal grace period; service records are then suspended. Names are not automatically resold to another customer. Contact support for recovery. Invitations, if issued, provide a separate 30-day test allocation without payment. Do not use the service for phishing, malware, impersonation, spam, illegal activity or attempts to access other users' resources. We may suspend abusive allocations. Public DNS records are public information.
Payments and support
Payment is processed by PayPal. We do not receive your card number. Billing statements may show RENDUN LIMITED. Contact support for billing problems, cancellation or refund requests; applicable statutory rights remain unaffected. No automatic refund or special financial promise is made by an AI agent. Keep your PayPal receipt and account credentials.
Data and security
We store your account email, salted password hash, hashed access tokens, DNS settings, payment identifiers, expiry dates and change history to provide the service. Session cookies are necessary for login. No advertising cookies or third-party analytics are used. Payment details are processed by PayPal under its privacy policy. Operations staff and hosting providers may process service data to maintain the system. The application is hosted on a Tencent Cloud server; service data may be processed outside your country.
Account and configuration data are retained while the account or allocation is active; billing and security records may be retained for accounting, fraud prevention and legal requirements. Contact support to request access, correction, account recovery or deletion. Backups may retain deleted data until their retention period ends. Do not store secrets or personal documents in public DNS records. Never share account passwords with agents; use scoped tokens.
