Guide · Limits

To keep the Service stable and fair, we set the limits below. When you reach one, the screen or your agent tells you why and when you can try again. Limits may change; when they do, this page is updated.

Last checked: Publication date

Uploading files

Item	Limit
Size of one file	Up to 100 MB (100,000,000 bytes)
How files are sent	Files up to 8 MiB in one piece; larger files in 8 MiB parts. Each part is checked with its SHA-256 fingerprint, and the whole file is checked again at the end.
Resuming	Choose the same file again within 24 hours of starting to continue where it stopped
Uploads at the same time	3 per member, each sending up to 4 parts at once
File name	Up to 255 bytes
Reference name, each alias	Up to 128 bytes each
Aliases per file	32
Relations per file	64
Workspace description	Up to 500 characters
Notes and correction notes	Up to 2,000 characters
Versions per workspace	1,000,000

Input over a limit is refused, not cut short.
Most Korean characters take 3 bytes. For example, a reference name can hold about 42 Korean characters.
Larger files are planned for a future paid plan. Until then, you can register large files hosted elsewhere as external links.

Storage and daily uploads

Item	Limit
Storage per member	1 GiB (1,073,741,824 bytes) across all workspaces you own. It does not refill; deleting frees space at once.
Who is charged	The workspace owner, including files uploaded by members with write access
Daily uploads	1 GiB per day per person uploading, reset at 00:00 UTC (09:00 in Korea). Bytes sent in failed or cancelled uploads also count.
Forks	No storage used (they refer to the same bytes). If the original is deleted, the storage moves to the owner of the oldest remaining fork, with a notice.
Warnings	One on-screen notice and one email each at 80 %, 95 % and 100 %
When full	Only new files and new versions with new bytes are refused. Reading, downloading, searching, deleting, forking and exporting still work. Nothing is deleted automatically.

Levels

Level	Storage	Daily uploads
0 (everyone at the start)	1 GiB	1 GiB
1 and above	Level quota table — fill when the level policy ships VERIFY	same

Levels never change the per-file limit of 100 MB.
If your level goes down, nothing is deleted. If you then use more than the lower amount, only new uploads are refused until you free space.
How levels are calculated is explained in Basic terms. The exact formula is not published.

Service capacity

Item	Limit
Total storage for the whole Service	15 TiB. If it is reached, new uploads pause for everyone until space is available. Everything else keeps working.
Maintenance	During read-only maintenance, reading and downloading work but changes are paused. See /status.

Workspaces and sharing

Item	Limit
Workspaces you can create	32
Members with access to one workspace	256
Changes to one workspace	About 10 per second; busier workspaces are asked to retry shortly

External links and video links

Item	Limit
Storage used	None (0 bytes)
Links per workspace	5,000
Length of a link address	Up to 2,048 bytes, `https://` only
Link checks	Up to 100 per workspace per day; each link at most once every 24 hours; status only, never the content

Reading and downloading

Counted per hour, starting on the hour. A new count starts at the next hour.

Who	Requests	Bytes downloaded
Signed-in member (including agents)	3,600 per hour	512 MiB per hour
Not signed in, per network group	3,600 per hour	512 MiB per hour

People who are not signed in are counted by a group number (one of 4,096) made from the IP address with a secret key. The IP address itself is not stored. Other people who share the same group may count toward the same total.
If you are signed in but your sign-in is invalid, you get an error instead of being counted as not signed in.
Responses include RateLimit headers so that tools can slow down before hitting a limit.

Item	Limit
Signed out after no activity	30 minutes
Longest sign-in	12 hours

Agent connections

Item	Limit
Active connections	16 per account
Connection period	1 hour, 1 day, 7 days or 30 days
Access token lifetime	10 minutes (renewed automatically within the connection period)
Workspaces per connection	1
Items per page in lists	Up to 64 (the rest on the next page)

Reports

Item	Limit
Open reports per member	16
Report statement	Up to 4,000 characters
Reports without signing in	5 per network group per day (UTC), and a limited number per hour for the whole Service

Reports that have been handled do not count toward these limits.

After leaving

Item	When
Account information, sign-in and connections	Deleted at once
Viewing files and public search	Stops at once
Physical erasure of file originals	About 36 to 45 days after leaving
Database recovery points	Up to 30 days
Encrypted backup copies	Up to 90 days

Details are in the Privacy Policy.
