The short version
The builder runs in your browser. Your prompt and the files you choose are read locally in the tab and are not uploaded anywhere. The site sets no cookies, runs no analytics and loads no third-party scripts. Today it shows no advertising.
Files and text you choose
Reference images, video clips, audio tracks, the first frame and the last frame, and the prompt you write are all handled inside your open browser tab. The page draws its preview from those files on your own screen.
These files stay in your browser only. They are not uploaded to this site or to any server of ours, because this site has no upload endpoint. Closing the tab clears them.
This is not a promise in the abstract: it follows from the site's own source. The published files (index.html, app.js, styles.css) contain no fetch(), no XMLHttpRequest, no WebSocket and no other network call that carries your content, and no external URL is loaded by the page.
Accounts, cookies and analytics
- No account, no sign-in, no profile.
- No cookies are set by this site.
- No analytics, no tracking pixels, no session recording.
- No localStorage, sessionStorage or IndexedDB: the page keeps nothing on your device between visits.
What the host receives
The site is a set of static files served from Cloudflare Pages. Your browser has to request those files from that server, so the host receives the ordinary technical request data any web server receives — for example your IP address, the time of the request and your browser's user agent string — in order to return the page. That data is handled by the hosting provider under Cloudflare's own privacy policy, not collected into an account or a profile here, because there is no account system on this site.
Nothing you write or upload is sent to us: there is no backend to receive it.
Advertising
The site currently runs no advertising. We may add third-party advertising in the future. If that happens, the advertising networks behind those ads may use cookies or similar technologies to choose and measure the ads you see, and their own privacy policies will apply to that processing. This page will be updated at the same time.
Changes to this policy
Any change is written onto this page together with a new "last updated" date at the top.
