Field notes
The data model avoids preset categories: a container is anything that holds something else, and users can build a hierarchy as deep as their actual storage. The page says the catalog remains on the device, works offline, and can be exported with photos. For cross-device sync, it describes passkeys and end-to-end encryption, while explicitly warning that losing every device also means losing access to synced data.
