Your data stays yours

Almost everything Ultarc knows about you lives in your browser, on your device. Your map, pre-test results, study progress, and plan stay local. Clearing your browser data clears them.

Account details. Email and password accounts stay in your browser's local storage. They never reach a server. If you continue with Google, we get your name, email, and profile picture to sign you in. We don't post or read anything else.

Study data. Your answers, levels, map colors, schedule, and preferences save per account in your browser so progress sticks between visits.

About you. Age, grade, classes, and test date help personalize your plan. They stay on your device with the rest of your study data.

If you join the coming-soon list, we store the email you submit so we can send launch and early-access updates. We don't sell waitlist emails. You can ask to be removed anytime.

When you press AI Help on a question, we send that question, its answer choices, and (if you've picked one) your current choice to Anthropic's Claude API to write a hint. Your name and account details are not included. See Anthropic's privacy policy for how they handle API data.

We use a few functional cookies and local-storage keys: your theme, your cookie preference, and (for Google sign-in only) an authentication session cookie. No advertising cookies, no cross-site tracking, no analytics scripts today.

The site is hosted on Netlify, which keeps standard server logs (like request IP addresses) to run the service.

Ultarc is built for students, including students under 18. Because study data stays on the device, a parent or guardian can review or remove it from the browser. Parents with questions can reach us through the Creator page.

Delete your data anytime: log out and clear this site's browsing data, and everything stored locally is gone. To disconnect Google sign-in, remove Ultarc from your Google account permissions.

If we ever move accounts to a real database (for example, when payments launch), we'll update this policy first and say clearly what changes.
