This policy explains how 4px LLC (“we,” “us”) handles personal information in connection with UIXHERO Design QA (design-qa.com).
When you contact us or request an initial consultation, we collect your company name, your name, your email address, and what you would like to discuss (including any relevant URLs). When you request materials, such as the full PDF of our sample report, we collect your email address.
Quick Design QA (free) and the UI Review (paid) point out UI problems in a screenshot of a web page or app screen that you send us.
We do not send your email address, IP address, or device information to the AI.
Except as required or permitted by law, or for the service providers in section 06 and the analytics in section 07, we do not share personal information with third parties without your consent.
We are a company in Japan, and Japanese law requires your consent before we send personal information abroad. If you agree before uploading, we send your screenshot and the text you typed into the form (section 02) to OpenAI or Anthropic. We send it to one of them; if that company's service fails, we also send it to the other.
We keep a record that you gave this consent: for 90 days for Quick Design QA, and for about 13 months with your order record for the UI Review.
Where needed to run our services, we may use outside service providers for parts of our work, such as sending email and managing forms. We choose them carefully and oversee how they handle your information.
To understand how the site is used and to improve our services, this site uses Google Analytics (GA4), an analytics tool provided by Google. Google Analytics uses cookies to collect traffic data, such as when you visited, which pages you viewed, which site referred you, and the browser and device you used. This information is sent to and stored by Google. It does not include information that directly identifies you, such as your name. We use this data only to analyze and improve our services. You can opt out by disabling cookies in your browser or by installing the Google Analytics Opt-out Browser Add-on. For details of how Google handles the data, see Google's privacy policy.
If you ask to access, correct, or delete the personal information we hold about you, we will verify your identity and respond promptly. Please contact us at the address below.
We may update this policy when needed and will announce significant changes on this site.
