It does not send push notifications.

Storage

Up to 512 MB on your Personal Cloud.

Its address

Works best with its own address. A Personal Cloud shared through Cloudflare can give it one; on a private Personal Cloud on Tailscale it opens under your Personal Cloud’s address, where it may not work fully. Private and shared Personal Clouds
