Privacy Policy

Last updated 5 August 2026. Hi3D has no accounts, so there is far less to explain here than on most privacy pages — but what there is, we set out plainly.

What We Collect

We do not ask for your name, your email address or any other identifying detail, because the generator does not require an account. There is nothing to sign up for and no profile attached to your generations.

When you use the tool we necessarily receive three things: the image you upload, the 3D model produced from it, and ordinary server request data such as your IP address, browser user agent and the time of the request. The request data is used to apply the fair-use rate limit, to detect abuse, and to diagnose errors. We also load Cloudflare Turnstile, which performs a privacy-preserving check that you are a human rather than an automated script.

Your Images and Models

Uploaded images and generated 3D models are stored only as long as the pipeline needs them and for a short window afterwards so you can download your result. They are then deleted automatically. We do not build a public gallery from user uploads, and the examples shown in our own gallery are our own material.

We do not use your uploads to train models. If you upload something sensitive, the safest assumption on any online service is still that you should not — but as a matter of policy, your images are processed to fulfil your request and for nothing else.

Analytics and Cookies

We use a self-hosted analytics installation to count page views and understand which pages are useful. It records aggregate information such as page path, referrer, approximate country and device type. It does not use advertising cookies, does not follow you across other websites, and does not build an advertising profile.

A small number of functional cookies may be set to remember your language preference and to support the rate limit and bot check. We do not sell data to anyone, and we do not run third-party advertising trackers on this site.

Third Parties

Running the service involves a short list of providers: a hosting and content delivery provider that serves this site and its images, Cloudflare for the Turnstile bot check and network protection, and GPU compute infrastructure that performs the reconstruction itself. Each of these processes data only to deliver the service. Some pages link to external websites; once you follow such a link, that site's own privacy policy governs your visit.

Your Rights and Contact

Because we hold no account data, there is usually no personal profile to access, correct or delete. If you believe we hold information relating to you and want it removed, or if you have any question about this policy, write to [email protected] and we will respond. Should this policy change materially, we will update the date at the top of this page.
