Not rated. Nobody has said who this app is suitable for, so Personal Clouds and the Oikou app treat it as 18+.

Internet

It asks to reach nothing on the internet.

Personal Cloud tools

None. It uses nothing from your Personal Cloud beyond its own storage.

Notifications

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
