In order to make money from your content you always have to be able to show that you have the ID’s and paperwork.
Which is great, until something goes wrong.
You can lose the papers in moving house, computers can die, laptops break or get stolen, plus all the usual fire and flood worries. Exe's have been know to trash things on their way out. And if that happens, you can get your content back from the sites by just downloading, but what about all the paperwork?
You can’t rely on them having kept copies.
Under GDPR (and/or other privacy laws) they might well have simply noted that “ID’s and releases have been provided” and perhaps logged a couple of details, but NOT have kept the originals. And even if they have, they might not be willing to give them to you*
Our Secure Vault offers a nice free backup store for your encrypted records.
* Data protection applies to PERSONAL data. If we do a scene and I give you my ID, which you upload to the sales platform. Later, your partner trashes your PC. You want to put the scene on a new platform. You grab the scene from the first one, but what about the ID's and Model Releases? MY passport is MY personal data, not yours. The first platform declines to give it to you. So you can't sell the scene on the second one.
