⚠️ Legal Review Notice: This privacy policy is provided for informational transparency for an open-source educational project. It has not been formally evaluated or certified by licensed legal counsel and requires formal legal review to ensure full regulatory and jurisdictional compliance.

            Key Summary for Students & Parents:

            • Mission PlusTwo is completely free and open-source.

            • You can use 100% of the planner without signing in (all study data stays solely on your phone or computer).

            • If you choose to sign in with Google, we store your study checklist and your Google display name/email solely to sync progress across your devices.

            • We do NOT run commercial ads, sell student data, or track your behavior across third-party websites.

1. Who We Are

Mission PlusTwo is an open-source, non-profit community project built for Kerala Higher Secondary (+2) and Plus One (+1) Improvement students preparing for the Directorate of General Education (DHSE) exams.

2. Data We Collect and Why

We practice strict data minimization:

Guest Mode (Default): When you use Mission PlusTwo without signing in, your syllabus selections, completed chapters, and study timetable are stored entirely in your device's browser localStorage. No personal study information is transmitted to our servers.
Google Sign-In (Optional Cloud Sync): If you tap "Connect Google Account" to sync your checklist between your smartphone and computer, we receive and store:
- Your Google Display Name (to display your name in the navigation bar).
- Your Google Email Address (to identify your study plan document in Cloud Firestore).
- Your Study Plan JSON data (target exam date, completed chapter IDs, subject priorities).
Pseudonymous Analytics (Google Analytics via Firebase): We use Google Analytics (measurement ID G-12KPP3ZZ80) configured for pseudonymous usage metrics.
- Google Signals and Ad Personalization features are permanently disabled (allow_google_signals: false, allow_ad_personalization_signals: false).
- No direct Personally Identifiable Information (PII) such as student names, phone numbers, or email addresses are attached to analytics events.
- Cookies and Pseudonymous Identifiers: Google Analytics operates using browser cookies and storage identifiers:
  - _ga: A first-party cookie used to distinguish unique browsers or devices, containing a pseudonymous client identifier. Stored for up to 2 years.
  - _ga_12KPP3ZZ80: A session cookie used to maintain session state across page reloads. Stored for up to 2 years.
  - A pseudonymous Client ID generated on device by Google Analytics to aggregate related user flows.
- Only aggregated lifecycle milestone events are recorded: opened, setup_started, plan_created, first_task_checked, and returned_day3 to evaluate app stability and user retention.
- The analytics SDK is loaded lazily on demand to optimize performance.

3. Student Data Protection Principles & Minor Notice

Many Plus One and Plus Two students in Kerala are minors (between 15 and 18 years old). We design our application with student privacy in mind:

We do NOT track or profile children's browsing behavior across third-party websites.
We do NOT serve targeted advertisements, sponsored commercial content, or sell user records.
We do NOT process data detrimental to a student's physical or mental well-being.
Parental Consent Gate (DPDP Act 2023): In accordance with Section 9 of India's Digital Personal Data Protection Act 2023, students under 18 must confirm affirmative parental or guardian consent before linking a Google account for cloud synchronization. An explicit confirmation gate is presented prior to OAuth authentication. Offline Guest Mode remains accessible at all times with zero personal information collected.
Students or parents may delete their cloud account and all study data at any time directly through the "Reset Plan" button in Settings, which permanently deletes the Firestore cloud document.

4. Data Storage & Security

Cloud data is hosted securely using Google Cloud Firebase (Firestore) in compliant data center regions. Access is governed by strict security rules ensuring that only your authenticated Google account can read or write your study document.

5. Your Rights

You have the right to inspect, export, or delete your study data at any time:

Export: Tap Settings → Export Plan to download a local JSON backup.
Delete: Tap Reset Plan to permanently delete both your local browser storage and cloud document.
