Privacy
MailDNS keeps what it needs to run the API safely, and nothing about you beyond that. Last updated October 18, 2026.
This website
- No cookies, no analytics, no advertising, and nothing loaded from other companies: fonts and scripts come from this site.
- Like any web server, ours and the network providers in front of it keep standard request logs: the address a request came from, the page, the time and the browser's user agent. We use them to keep the site running and to deal with abuse.
The API
For every call we record:
- which key made it, and the IP address it came from;
- the command or path, the domain it named, the result and how long it took;
- for every change, the records of the host before and after.
We use this to run and secure the service, enforce limits, and answer the question "who changed this record, and when". It is kept while your key is active, and afterwards for as long as we may need it to answer questions about past changes.
Registrar keys you connect
- When you connect a registrar account, its API key is checked on the spot and kept so MailDNS can make the record changes your keys ask for. It is never shown again, on the connect page or anywhere else.
- It is used only for DNS records on the domains you chose, and to keep the list of those domains up to date. Never for nameservers, registration, renewals or transfers.
- To disconnect an account, ask the person who set up your MailDNS account. You can also revoke the key at your registrar at any time.
The records you write
DNS records are public by design: once a record is live, anyone can look it up. Don't put anything in a record that you would not publish.
What we never do
We don't sell this information or use it for advertising. We share it only with the providers needed to run the service, or when the law requires it.
Questions
Accounts are by invitation, so there is no public inbox. Ask the person who issued your key; they can reach us directly.
