Privacy Policy

Last updated: 12 October 2026

This policy explains what information HyperTransformer AI (“we”, “us”), a product from Build with Priyanka, collects when you use this website, how we use it, and the choices you have.

1. Information we collect

  • Your Google account details. When you sign in with Google we receive your name, email address, profile picture and Google account ID. We never see your Google password.
  • Your practice progress. Your Coding Game answers, Study Cards you viewed, flagged or edited, your AI Interview Prep questions, answers, scores and levels, the subjects you chose, and your settings. This is stored in our database linked to your account, and in your browser’s local storage.
  • Messages you send us through the contact form: your name, email address and message.
  • Technical information. Your IP address is used briefly to prevent spam on the contact form. Our hosting provider may record standard server logs such as IP address, browser type and the pages requested.

2. How we use it

  • To provide the service: sign you in, save your progress and sync it across your devices.
  • To generate and grade AI Interview Prep questions.
  • To reply to your messages and support requests.
  • To keep the service secure and prevent abuse.
  • To show advertising that helps fund the service (see section 4).

3. Services we rely on

  • Google for sign-in (Google Privacy Policy).
  • NVIDIA AI models power AI Interview Prep. The questions you are asked and the answers you type are sent to NVIDIA’s API to create questions and grade answers. Please do not include personal information in your answers.
  • MongoDB Atlas stores accounts and progress, and Vercel hosts the website.
  • Voice features use your browser. Reading questions aloud happens on your device. Voice answers use your browser’s speech recognition; in Google Chrome, for example, your browser sends the audio to Google to turn it into text. We never receive or store audio.
  • Google Analytics counts visits and shows us which pages and sections are used, so we can improve the site. It uses cookies and receives your IP address and browser details (how Google uses this data).
  • Google Fonts provides the typefaces used on the site.

4. Cookies, local storage and advertising

  • ip_session: keeps you signed in for up to 30 days. It cannot be read by scripts on the page.
  • ip_oauth_state and ip_oauth_next: last 10 minutes and protect the sign-in process.
  • _ga and _ga_*: Google Analytics cookies that tell visits apart, kept for up to 2 years.
  • Local storage: your progress, theme and display preferences on this device.

We may show advertisements from Google AdSense and other advertising partners. Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to our users based on their visit to this site and/or other sites on the Internet.

You can opt out of personalised advertising by visiting Google Ads Settings, and opt out of some third-party vendors’ use of cookies for personalised advertising at www.aboutads.info. Where the law requires it, for example for visitors in the European Economic Area and the UK, we ask for your consent before advertising cookies are used.

5. Sharing

We do not sell your personal information. We share it only with the service providers above so they can run the service for us, or when the law requires it.

6. How long we keep it, and deleting it

We keep your account and progress while you use the service. To delete your account and all your progress, email shahasanepriyanka@gmail.com from the address you sign in with and we will delete it. Logging out removes your progress from that browser; it stays saved to your account.

7. Your rights

Depending on where you live, you may have the right to access, correct or delete your personal information, or to object to how we use it. To make a request, contact us.

8. Children

HyperTransformer AI is not directed at children under 13, and we do not knowingly collect information from them. If you believe a child has given us information, contact us and we will delete it.

9. Security

We use HTTPS, signed sign-in cookies and access-restricted storage to protect your information. No method of transmission or storage is completely secure, but we work to keep your information safe.

10. Changes to this policy

If we change this policy we will update the date at the top of this page. Significant changes will be highlighted on the site.
