Copyright starts the moment you create something. Here is how to prove it: a dated ownership certificate on every file, free, plus what official…
Your work is yours the moment you make it. What people usually need is proof: a dated record that shows the file existed, that it is yours, and that a stranger can check. That is what sinima. gives you on every upload, free, in about a minute.
You already hold the copyright in work you made yourself. Writing, film, music and images are protected from the moment they are recorded in a fixed form, in every country signed up to the Berne Convention, which is almost all of them. There is no form to fill in for that part. The trouble is that holding a right and proving you held it first are two different things. Most arguments are lost on evidence, not on law.
Create a free account, upload the file, and you get a dated ownership certificate in your own name, with a code anyone can check from a link. The certificate records the file itself, the date and time it arrived, who you are, and anything else you choose to add: your co-creators, your lawyer, your point of contact, and any registration you already hold elsewhere. You can download it, print it, email it, or share a link with a client or a lawyer.
In some countries, registering with a national copyright office gives you extra remedies in court, and in the United States registration is usually needed before you can file a lawsuit. Registration and proof are not the same thing, so do both: keep the dated certificate for everyday disputes, takedowns and client work, and register formally for the work you would go to court over. You can record any registration number on your certificate so it all sits in one place.
No. In nearly every country the right exists from the moment you record the work in a fixed form. Registration is an extra step that can strengthen what you can claim in court, and in the United States it is normally required before you can sue.
You need a dated record of the exact file. Upload it here and you get a certificate carrying a unique mark of that file, the date and hour it arrived, and your name, with a code a stranger can check from a link.
Someone can wrongly claim it, which is why dated proof matters. They cannot take the right from you by posting it first. With a certificate in hand you can answer a claim, or send a takedown, with evidence attached.
A notice tells people the work is claimed, but it proves nothing about the date. Mailing yourself a copy is weak evidence and easy to challenge. A dated certificate tied to the file itself is far stronger, and takes about a minute.
No. Certificates are included on the free plan, with no card required.
Yes. You can record a refusal against each file, and that answer travels with it. Nothing is licensed or offered to anyone without you saying yes first.
