Why it matters

Kifuna codes are printed on things people trust: menus, signs, business cards and packaging. Every one redirects through kifu.to, so a single scam code can harm the people who scan it and get kifu.to flagged by browsers and mail filters, which would break every customer's printed codes. This policy is part of our terms of service.

What codes may not open, contain or host

And don't use Kifuna in bulk or by automated means beyond the fair-use policy, try to get around its limits or checks, get into accounts that aren't yours, or attack or probe Kifuna or kifu.to. If you find a security problem, tell us at [email protected].

How we check codes

Reporting a code

Anyone can report a code; the pages people see when they scan a blocked or inactive code link to the form. A report gets the code checked again at once, and again later for a scam or malware. Reports alone don't block a code its owner has been using for a while, so nobody can take down a printed code just by reporting it, but several reports from different networks can hold a new one. We never tell the owner who reported a code, and we don't email reporters, except to reply to legal requests.

If we block a code or hold a change

Child sexual abuse material

We never allow it. A single report about a PDF we host holds the code at once while a person reviews it, and we keep the evidence. We report apparent child sexual abuse material to the National Center for Missing & Exploited Children, as US law requires, and may close the account.

If a code opens or hosts something that infringes your copyright, report it and choose “It uses my copyright or trademark”, or write to [email protected]. Tell us the code, by its kifu.to link or ID, the work you say it infringes, and your email address. A person reads every one, and we reply.

If we decide the code infringes, we block it and tell its owner why, and the owner can ask for a review, as above.

For a trademark complaint, a court order or another legal request about a code, use the report form and choose the closest reason; a person reads every one, and we reply. Law enforcement can write to [email protected]. We give out information about an account only with valid legal process, or in an emergency involving danger of death or serious injury, and we tell the account's owner first unless the law or the request forbids it.
