# .app domains

> Google Registry TLD for applications. HSTS-preloaded across every major browser, so HTTPS is required from day one.

`.app` is run by Google Registry and aimed at app makers and product sites. The whole TLD is on the [HSTS preload list](https://hstspreload.org/), which means every major browser will refuse to load an `.app` site over plain HTTP. You need a valid TLS certificate before the site can serve a single page.

| -------------------- | ----------------------------------------------------- |
| Registry             | Google Registry                                       |
| Registration period  | 1 to 10 years                                         |
| Renewal grace period | 30 days after expiry                                  |
| Redemption period    | 30 days after grace                                   |
| Transfer lock        | 60 days after registration or transfer (ICANN policy) |

## Eligibility

Open.

## Features

* **HTTPS-only.** HSTS preload is enforced at the TLD level. There is no opt-out.
* **WHOIS privacy.** Free, applied by default.
* **DNSSEC.** Supported.
* **IDN.** Supported.
* **Auth (EPP) code.** Issued instantly from the [domain panel](/domains/management/panel).

## Things to know

If the site renders blank with a certificate error, it's almost always the TLS cert. Noxity hosting accounts auto-provision Let's Encrypt for added domains, but if the domain points at an external server you'll need to install your own cert before the site loads.
