Cookie-Free Notice

You may have noticed something missing from StudyBonk: a cookie consent banner. That's not an oversight or a design shortcut — StudyBonk sets zero cookies and loads zero trackers, so there is nothing to consent to. This page explains what that means and what the site uses instead.

Zero cookies, zero trackers

StudyBonk does not set any cookies — not analytics cookies, not advertising cookies, not even strictly-necessary ones. It also loads no third-party scripts, pixels or fingerprinting libraries of any kind.

You don't have to take this on faith. The site is open-source at github.com/TuffyCoder/StudyBonk, and you can inspect every page's network activity in your browser's developer tools: the cookies tab for studybonk.pages.dev will stay empty.

What we use instead: localStorage

To remember your progress between visits, StudyBonk uses your browser's localStorage — a standard web feature that lets a site save small amounts of data on your own device. Your XP, streaks, flashcard decks, focus stats, theme preference and encrypted AI chat history are written there.

The crucial property: localStorage data never leaves your device. It is not attached to requests, not readable by other websites, and never transmitted to StudyBonk's servers — the site keeps no servers of its own to send it to.

• sb.theme — light or dark mode preference.
• sb.gamification — XP, streaks, badges and quests.
• sb.srs and sb.userDecks — review schedules and custom decks.
• sb.focusSettings and sb.focusStats — timer settings and session history.
• sb.ai.history.enc, sb.ai.memory and sb.devicekey — encrypted local AI data.

How localStorage differs from cookies

Cookies and localStorage are both browser storage, but they behave very differently where privacy is concerned — which is why a site full of localStorage can honestly call itself cookie-free.

• Cookies are sent to a server with every request; localStorage stays on your device, always.
• Cookies are the backbone of ad tracking and session profiling; localStorage here holds only your own study data.
• Third-party cookies can follow you across sites; StudyBonk's localStorage is readable by no other site.
• Clearing cookies in your browser does not necessarily clear localStorage — see the next section.

How to clear your StudyBonk data

If you want a fresh start — or you're on a shared computer — you can wipe everything StudyBonk has saved. In most browsers: open Settings, find the privacy or site-data section, view site data for studybonk.pages.dev, and delete it. Browsers usually also let you clear site data for the site you're currently on via the padlock icon in the address bar.

One friendly warning: clearing site data erases your XP, streaks, decks and AI history permanently — that's the flip side of a no-account design. Export a JSON backup from the dashboard first if you want to keep your progress.

• Browser settings → Privacy → Site data → studybonk.pages.dev → delete.
• Or: padlock icon next to the address bar → site settings → clear data.
• Export a dashboard backup first if you want to keep your progress.

Theme preference

The one thing that might feel like personalization is your light or dark mode choice, stored under the sb.theme key. Even that stays in your browser — switch devices and the site starts in its default theme until you choose again. No advertising ID, no cross-site profile, no 'personalized experience' built from your data: just a preference flag on your own machine.
