Anonymized Academic Context
The AI engine only receives anonymized academic data needed to fulfill your request (e.g., "Student has 45% accuracy in Circular Motion; generate a 3-day revision timetable"). Personal passwords, banking details, and full identities are never sent to the LLM backend.
Session Ephemerality
You can clear your AI study coach chat sessions at any time directly through the student dashboard, instantly purging cached conversation logs from your active profile.
4. Telegram Quiz Bots Data & OTP Security
Examinex provides two distinct Telegram bot workflows: our official platform bot (@examinexQuizbot) and private instructor bots.
| Bot System | Data Processed | Data Usage & Retention |
|---|---|---|
| Official Platform Bot (@examinexQuizbot) | Telegram User ID, username, temporary 6-digit OTP verification code, and MCQ quiz responses. | Links your Telegram account to your Examinex web student profile, delivers timed quizzes, updates your web exam history, and sends exam countdown alerts. |
| Verified Instructor Bots | Telegram chat ID, group ID, student Telegram handle, and poll participation scores. | Allows tuition teachers to send daily practice polls to their class groups and record student engagement in the instructor portal. |

- Personalized AI Tutoring: Enabling Examinex AI to formulate tailored revision timetables and target lesson weaknesses.
- Account Security & Verification: Verifying accounts via OTP, preventing credential stuffing, and resetting passwords.
- System Notifications: Sending essential SMS/email alerts regarding exam results, membership renewals, and scheduled maintenance.
8. Anti-Cheat & Exam Integrity Monitoring
To preserve academic honesty in competitive exams and island-wide tournaments, Examinex utilizes non-invasive anti-cheat telemetry:
Server-Authoritative Timers
Exam timers run entirely on the server. Tampering with local device clocks or closing browser tabs will not stop the exam clock, preventing unfair time extensions.
Focus & Tab Switching Detection
During competitive tournament examinations, our exam engine records tab blur events and multiple device logins under the same account to detect unauthorized collaboration.
11. Security Safeguards & Encryption
Examinex implements multi-layered security controls to protect your data from unauthorized access, alteration, or disclosure:
HTTPS / TLS 1.3
All web traffic between your browser and Examinex is encrypted in transit using 256-bit TLS/SSL certificates.
Bcrypt Password Hashing
All passwords are irreversibly hashed with cryptographic salt factors, ensuring credentials cannot be reversed.
Role-Based Access
Administrative access to database records is restricted to verified personnel with multi-factor authentication.
12. Data Retention & Account Deletion
We retain your personal and examination records as long as your account remains active to provide continuous revision progress tracking across your A/L preparation years.
Right to Erasure (Account Deletion):
You may request the permanent deletion of your Examinex account at any time. When an account is deleted:
- Your personal contact information, passwords, and profile details are permanently purged from active databases.
- Historical exam attempts are either anonymized for statistical reporting or permanently deleted.
- Financial transaction records are retained only for the legally mandated period required by Sri Lankan tax and auditing legislation.

Under the Sri Lanka Personal Data Protection Act No. 9 of 2022 (PDPA) and international standards, you have the following rights:
