| Binding | retention-clamped The identity gate is the one that usually closes a Chinese pan, and this one is open; what binds is the 30-day inactivity clock, which makes it a working set and not an archive. |
|---|
| Identity | email the register page offers email and password as the primary path with 'Sign up with phone instead' as the alternative; no card, no ID, no +86 requirement stated |
|---|
| Egress | downloads are metered by tier rather than by byte: free accounts have no published volume cap but a slow channel, Standard is stated at 'up to 5MB/sec', and Super removes the limit; no per-GB egress price is published |
|---|
| Per-object cap | 20 GB per file on the free tier; 30 GB on Standard (20000000000 bytes) |
|---|
| Retention | files are deleted after 30 consecutive days without a sign-in on a free account, or 365 days on a paid account (30 days) |
|---|
| Interface | rest, webdav, cli |
|---|
| Tooling | first-party desktop client and a WebDAV endpoint; the free tier advertises WebDAV and the Super tier advertises 'WebDAV batch download'; the nfd-parser project ships a ct driver |
|---|
| Composes with | the only Chinese pan in this survey that a foreigner can self-register for with an email address alone, so it is the one that can sit under a self-hosted bridge without a +86 number |
|---|
| Reliability | Over-quota triggers deletion of the excess without prior notice, and the inactivity clock deletes a free account's files at 30 days; a monthly sign-in cron keeps it alive and nothing else does. |
|---|
| Notes | 5 TB free, 20 GB per file, email-only registration, WebDAV advertised. The 30-day inactivity deletion is the number that decides how it can be used: a monthly cron job keeps it, and nothing else does. Terms section 3.2.7 also caps the account at 200,000 files, which at 20 GB per file is a 4 PB nominal ceiling and therefore not the constraint. |
