Privacy Policy
Who we are
pixstl is operated by flreey (HK). For any privacy question, contact hello@pixstl.com.
What we collect
When you visit pixstl, our hosting provider processes technical data that every web request contains, such as your IP address, browser type and the page requested. This is needed to deliver pages and to block abuse.
Relief, lithophane and converter tools process your images in your browser; they are never uploaded. Photos you send to the AI 3D tool are uploaded to generate the model and deleted after 24 hours; generated models are kept for 30 days so you can download them again.
If you create an account, our sign-in provider stores your email address and sign-in details. We store your account identifier, your plan, your credit balance and a record of your purchases so the service knows what you can use.
If you email us at hello@pixstl.com, we keep the message and your address only as long as needed to reply.
Cookies
pixstl does not set cookies for tracking or advertising.

How long we keep data
Request logs are kept by our hosting provider for a short period for security and debugging. Analytics records (pseudonymous visit and event data) stay on the analytics service and are used only for aggregate reports. Account data is kept while your account is open; payment records are kept as long as tax law requires. We do not sell personal data.
