What Marcus does with your data
Marcus does not train, fine-tune or evaluate any AI model. We have no model of our own to feed. Your prompts and the files generated for you are stored so you can open, revise, download and publish the project, and for nothing else. We do not sell project data and do not pass it to advertising or analytics networks.
What counts as your data
Your data is the brief you type, the revisions you ask for, and the HTML, CSS and JavaScript Marcus writes for you. It lives in a project that belongs to your account (or, before you sign in, to the browser session that started it).
Anthropic Claude writes the pages
Every build is generated by Anthropic's Claude. To do that, the text of your request is sent to Anthropic and the generated files come back to our server. That step is governed by Anthropic's own terms and privacy policy, not by ours, so if this matters for your project, read Anthropic's privacy policy before you build. Do not put passwords, customer records or other secrets into a brief.
Where it is stored
Project files, the project database and server logs sit on our server in Estonia, in the EU. Published pages are served from the same machine at aimarcus.love/p/your-project.
Deleting a project
Deleting a project removes its database record, every revision and its folder of files from the server straight away. There is no undo, so download the ZIP first if you want to keep a copy.
