The short version
Because we run no advertising or tracking cookies, there is no consent banner to click through. What we do store is listed here in full, and you can clear all of it from Settings at any time.
What we store in your browser
| Item | What it holds | Why | How long |
|---|---|---|---|
| Firebase auth session | A sign-in token from Google Firebase Authentication. | Keeps you signed in so you are not asked for your password on every page. | Until you sign out or it expires. |
| ptp-attempts-* | Your quiz and mock-exam attempts. | Powers progress, readiness scores, and category mastery — and keeps them working offline. | Until you clear study data or delete your account. |
| ptp-prefs-* | Your notification and study preferences. | Remembers your choices, like default quiz length and reminder time. | Until you clear study data or delete your account. |
| ptp-exam-date-* | The certification exam date you set. | Drives the countdown on your dashboard. | Until you change or clear it. |
| ptp-tutor-usage | A per-day count of AI tutor messages. | Enforces the fair-use limit that keeps the tutor available to everyone. | Resets daily. |
| ptp-support-queue | Support messages that could not be delivered yet. | Makes sure a message you typed is not lost if you were offline. | Until the message is delivered. |
Third parties
Google Firebase provides our authentication, database, and hosting, and sets the sign-in token above. Google Fonts serves the typefaces used across the site. Our mobile app also uses Firebase Crashlytics for crash diagnostics. None of these is used to build an advertising profile of you.
Clearing it
Open Settings → Data and privacy to clear the study data stored on this device, or to delete your account and everything attached to it. You can also clear site data through your browser's own privacy settings — signing you out and resetting local progress, though anything already synced to your account stays with your account.
