Cookie Policy
Last updated: October 15, 2026(Security & Privacy Hardening)
This Cookie Policy explains what cookies and browser storage mechanisms Project Pak-LLM uses, what data they store, and how you can control them.
1What Are Cookies?
Cookies are small text files placed on your device by websites. We also use related browser storage technologies including localStorage and sessionStorage. This policy covers all such mechanisms.
2What We Store & Why
| Storage Key | Type | Purpose | Duration | Required? |
|---|---|---|---|---|
| theme | localStorage | Remembers your dark/light mode preference | Persistent | No |
| chatFontSize | localStorage | Remembers your preferred chat text size | Persistent | No |
| hasSeenFreeTierNotice | localStorage | Remembers if you've dismissed the server cold-start notice | Persistent | No |
| Firebase Auth Token | IndexedDB (Firebase SDK) | Maintains your authenticated session after login | 1 hour (auto-refreshed) | Yes — required for login |
| pak_llm_guest_id | 1st-party cookie | Guest visitor ID for performance telemetry across sessions (strictly opt-in) | 30 days (or until opt-out) | No |
| pak_llm_guest_info | 1st-party cookie | Stores browser parameters (screen size, locale language, timezone) for layout optimization | 30 days (or until opt-out) | No |
| Vercel Analytics & Speed Insights | 1st-party cookie (Analytics only) | Anonymized page-view statistics and Web Vitals performance metrics; no personal data, not tied to any visitor or IP | 90 days | No |
3What We Do NOT Use
We do not use:
- Third-party advertising or tracking cookies (Google Ads, Facebook Pixel, etc.)
- Cross-site tracking or fingerprinting
- Cookies that track you across other websites
- Session recording tools (e.g., Hotjar, FullStory)
4How to Control Storage & Opt-Out
You have full control over your telemetry preferences. Use the interactive controls below to instantly revoke consent and purge all guest telemetry cookies from your device:
You can revoke your consent and permanently purge guest identifiers (pak_llm_guest_id, pak_llm_guest_info) at any time. Clicking below will instantly delete all non-essential cookies and reload the consent preferences.
You can also clear all localStorage and cookies at any time via your browser settings (Settings → Privacy → Clear Browsing Data). This will reset your theme preference and dismiss-notice state, but will also log you out of the workspace.
To selectively remove a single key, open your browser's DevTools → Application tab → Local Storage → right-click the key and select Delete.
Blocking all cookies will prevent Firebase authentication from working, which means you will not be able to sign in to the workspace.
