Collecting and Using Your Personal Data

Types of Data We Collect

Personal Data

When you use the Service, we may ask for personal information that can be used to contact or identify you. This may include:

  • Email address
  • Usage Data
  • Information from your sign-in provider
  • Cookies

Usage Data

Usage Data is collected automatically when you use the Service. It may include your device's IP address, browser type and version, the pages you visit, the time and date of your visit, the time spent on those pages, and other diagnostic data.

Information from Third-Party Sign-In Services

You can create an account and sign in through the following services:

  • Google

You can also sign in using an email magic link, delivered through Cloudflare Email.

If you register through, or give us access to, a Third-Party Sign-In Service, we may collect Personal Data already associated with that account, such as your name, email address and profile picture.

Payment Information

Stripe processes card payments for Mizhi Smart. We do not store full card numbers.

Payments are processed by our payment providers. We do not receive or store your full card number. We receive the details needed to manage your purchase, such as the order amount, the date, your billing country and the status of the payment.

Tracking Technologies and Cookies

We use Cookies and similar technologies to keep you signed in, remember your preferences, and understand how the Service is used. These may include beacons, tags and scripts that collect and track information to improve and analyze the Service.

A first-party Cookie also records how you arrived at the Website (the referring website, campaign tags in the link, and the page you landed on). When you create an account or start a purchase, we store this with your account so we can see which channels bring customers.

We use self-hosted Umami and Google Analytics 4 to measure page visits, referring websites, campaign sources, and interactions such as signing in, starting a generation, downloading a result, and purchasing credits. Google Analytics may set analytics cookies. Purchase events include an order identifier, amount and currency. Our custom analytics events do not include your prompts, uploaded images, generated images, email address or payment-card details. Cloudflare also collects website performance and traffic measurements.

You can set your browser to refuse all Cookies or to tell you when a Cookie is being sent. If you refuse Cookies, some parts of the Service may not work.

Photos and Faces

Some features let you upload photos, and those photos may show human faces. We use uploaded images only to produce the generation you request, such as editing the background or visual style of an image.

We do not use uploaded photos for facial recognition, and we do not create biometric identifiers from them.

We do not publish your uploaded images or generated results in our gallery, advertising or other promotional materials without your separate, explicit permission.

Uploaded images and stored results are retained until you request deletion, subject to operational and legal retention needs. We do not currently promise an automatic deletion period. Media links may be accessible to anyone who has the URL; do not upload confidential material. Third-party providers handle copies under their own retention policies.

By uploading a photo, you consent to this limited use of the image for the purpose of creating your result. You must only upload photos of yourself, or of people who have agreed to their use.

When you start a generation, the text you entered and the photos you submitted are first checked by an automated content-safety service. If the check blocks a request, we keep a record of it (your account, the text, links to the photos and the reason given) so we can answer questions about the decision and prevent misuse.

Use of Your Personal Data

We may use Personal Data to:

  • Provide and maintain the Service, including monitoring how it is used.
  • Manage your Account, including your registration and access to the features available to registered users.
  • Process purchases and keep records of your credits and orders.
  • Contact you with service messages, and with news, offers and information about features similar to those you have used or asked about, unless you have opted out.
  • Handle your requests to us.
  • Analyze and improve: to analyze data, identify usage trends, measure the effectiveness of our promotional campaigns, and improve the Service and your experience.

Retention of Your Personal Data

We keep your Personal Data only as long as needed for the purposes in this Privacy Policy. We keep and use it as far as needed to comply with our legal obligations (for example, where the law requires us to keep it), resolve disputes, and enforce our agreements and policies.

We also keep Usage Data for internal analysis. Usage Data is generally kept for a shorter time, unless it is used to strengthen security or improve the Service, or the law requires us to keep it longer.

Deleting Your Personal Data

You have the right to delete, or ask us to help you delete, the Personal Data we have collected about you.

You can update some of your information by signing in to your Account. To access, correct or delete any personal information you have given us, or to delete your Account, contact us at contact@flux3klein.net.

Security of Your Personal Data

We take the security of your Personal Data seriously and use commercially reasonable measures to protect it. No method of transmission over the internet or of electronic storage is completely secure, so we cannot guarantee absolute security.

You are responsible for keeping your Device and your sign-in credentials secure.

Third-Party AI Processors

To deliver our AI generation features, we work with third-party AI model providers.

  • Processors: fal.ai processes image generation and editing using Black Forest Labs models. Replicate processes prompt and image content checks using Llama Guard.
  • Data minimization: we do not share identifiers such as your account ID, email address, real name or precise location with these AI providers. Where technically possible, data sent for AI processing is de-identified.

Cloudflare provides hosting, D1 database storage, R2 media storage, email delivery, Turnstile verification and website measurements. Google provides optional social sign-in and Google Analytics 4. Stripe processes payments. Our self-hosted Umami installation measures visits and product interactions. First-party attribution cookies record referring domains and campaign parameters. Each provider receives the information needed for its service.

Your Choices

  • Opting out: if you do not want a particular provider to process your data, do not submit content to the generation or editing features.

Opting Out of Information Use

You can limit how we use your information:

  • Browser settings: set your browser to refuse Cookies. Some parts of the Website may then not work fully.
  • Marketing emails: use the unsubscribe link in any marketing email, or write to contact@flux3klein.net.
  • Account deletion: ask us to delete your account at any time by writing to contact@flux3klein.net. After deletion, we handle your personal information as required by applicable privacy law.

Children's Privacy

The Service is intended for users aged 18 and older. We do not knowingly collect Personal Data from anyone under 18. If you believe a minor has given us Personal Data, contact us and we will delete it.

Content Rules

The rules on what you may upload and generate are set out in the Content Restrictions section of our Terms of Service.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time, and we recommend that you review it periodically. Changes take effect when they are posted on this page, and the effective date at the top will change. We may also announce significant changes on the Website.
