Your stuff is your stuff

The short version

Your information is used to run the site and for nothing else. It is never sold, never used for advertising, and never shared with anyone. Not your account email, not your quiz scores, not which guides you opened. The one exception is the volunteer program: when you log hours and they are approved, your name and the approved hours are passed along so they can be credited, because that is the point of logging them.

The site is built and run by an IHHS student, for IHHS students, and the code is open source.

What gets stored, and where

The site only stores what's needed to make the features work. Specifically:

• Theme preference (light or dark), in your browser's localStorage.
• Reading progress: which guides you've opened and when, in localStorage.
• Reading time: how long you actively spend on each guide, counted only while the guide tab is open and you are scrolling, clicking or typing. Only tracked while you're signed in, in localStorage.
• Flashcard scheduling: which cards you've reviewed and when they're due next, in localStorage.
• Quiz scores: how many you got right and on which guide, in localStorage.
• Streak count: how many days in a row you've studied, in localStorage.

All of that lives on your device only. If you clear your browser data, it's gone. If you use a different device, it doesn't follow you.

Anonymous page counts

The site uses Vercel Web Analytics to count visits: which pages get opened, roughly how many people come by, what kind of device and browser they use, and which country they're in. It sets no cookies, it doesn't follow you to other sites, and it can't tell me who any individual visitor is. Repeat visits are matched with a temporary code that changes every day, so it can't even recognize you tomorrow. It has no connection to your account, so it can't link a page view to your quiz scores or reading time.

If you create an account

Accounts are optional. If you make one, the same data above is also synced to a cloud database (Supabase) so it follows you between devices. The only personal info attached to your account is the email address you signed up with, used solely so you can log back in. No name, no school ID, no anything else is collected.

One exception, and only because you'd want it: if you submit volunteer hours for a guide, the guide team reviewing that submission can see the reading time your account recorded on that guide, so honest hours get credited without a back-and-forth. They can also correct that number, for example to credit reading you did on paper. That view stays inside the site's admin pages.

Your email is never shared, never sold, never used for marketing, and never used to message you.

What is NOT collected

• No advertising trackers, no tracking pixels, no Google Analytics, no Meta Pixel. The anonymous page counter above is the only measurement on the site.
• No IP address logging beyond what the host (Vercel) does for basic abuse prevention. The page counter uses your address only to work out the country and doesn't store it.
• No third-party advertising. There are no ads, ever.
• No browser fingerprinting.
• No reading of your other tabs, other sites, or anything outside this site.

The AI tutor

When you chat with the tutor, the question you type plus the surrounding guide text gets sent to a third-party AI provider (Cloudflare Workers AI / Google Gemma 4) so it can write a reply. I don't store the conversation. The AI provider sees the prompt long enough to answer it; their privacy policy applies to that part. I don't tie tutor messages to your account, and I don't read them.

Your rights

• You can delete all your local data anytime by clearing site data in your browser.
• If you have an account, you can email me and I'll delete it and everything attached, no questions asked.
• You can use the site without an account. Then nothing about you leaves your browser except the anonymous page count above.

Changes to this policy

If anything here changes, I'll update the "last updated" date at the top.
