Write to us
Describe what happened and include the account email and, if relevant, the object key or link. The more specific the report, the shorter the thread. Paid plans are answered first.
hello@knapsack.myFaster than waiting for us
Cannot sign in
Request a password reset — the email arrives within a minute. If it does not, check the spam folder before writing to us; a surprising share of tickets end there.
An upload keeps failing
Check that the object is within your plan's limit and that the account has room. If a transfer always stops at the same percentage, try a different network — corporate middleboxes are the usual cause.
A link does not work for the recipient
Look at the link's expiry and download limit; one of the two is usually exhausted. Issuing a fresh link takes a moment and does not touch the underlying files.
Everything seems down
Check the status page first. If it is green and you are still stuck, tell us your country and network provider — that detail resolves most routing reports quickly.
Reporting abuse
If Knapsack is being used to distribute unlawful material or something that infringes your rights, email hello@knapsack.my with “Abuse” in the subject line, a link and a short description. We review such reports within one business day.
