What runs where
Every model is computed and drawn in your browser. Your code runs in a sandboxed Web Worker on your own machine; it is never sent to a server to be rendered or executed.
What is stored
- Your account: your email address, your username, your display name and the bio you write. You sign in with a link or a code sent to your email, or with a passkey; there is no password, so none is stored.
- Your designs: when you save a design, its code, its title and description, its versions, a thumbnail taken from the viewer, and the parameter presets you keep with it. A private design is visible to you alone; a public one to anyone with the link.
- Likes and forks: which public designs you liked, and which design a fork of yours came from.
- Sessions: the sign-ins of your account, with the browser they came from, so you can see and end them.
- Your draft: the code in the editor before you save it stays in your browser's local storage and never reaches the server.
What is not done
- Your personal data is not sold.
- Your designs are not used to train machine learning models.
- There is no advertising and no tracking across other sites.
- Data reaches a third party only where the service needs it: hosting, and the mail that carries your sign-in link.
Your rights
You can delete a design at any time from the design itself, and your account from its settings, which removes everything above; an export of your data is there too. For anything else, write to privacy@printparams.com.
