Privacy Policy
Last updated: September 2026 · HAZRI
1. Who we are
Hazri is operated by HAZRI ("we", "us", "our"). We provide a location-verified attendance system for educational institutions. This Privacy Policy explains what personal data we collect, why we collect it, and how it is stored and used.
2. Data we collect
| Data | Who provides it | Purpose |
|---|---|---|
| Email address | Teacher (account) | Authentication |
| Full name | Teacher (signup) & Student (submission) | Account display; attendance record |
| Roll number | Student (submission) | Unique identification per session |
| GPS coordinates (lat/lng) | Student device | Geofence verification; stored with record |
| Distance from class | Calculated server-side | Displayed to teacher on dashboard |
| Signature (image) | Student (optional, when session requires it) | Manual verification by teacher |
| IP address | Student device | WiFi-lock mode only (not stored otherwise) |
3. How we use your data
- Authentication: Email and password are used only to log teachers in. Passwords are hashed by Supabase Auth and never stored in plaintext.
- Attendance verification: GPS coordinates are compared to the teacher's recorded location server-side to enforce the geofence radius. We do not track movement or location history.
- Teacher dashboard: Attendance records (name, roll number, distance, time, optional signature) are displayed to the teacher who created the session.
- Export: Teachers can export their session data to Excel or PDF. We do not access or process exported files.
4. Data sharing
We do not sell, rent, or share your personal data with third parties for marketing or advertising. Data is shared only in the following limited cases:
- Supabase: Our database and authentication provider (supabase.com). Data is stored on Supabase-managed infrastructure. See Supabase's Privacy Policy.
- Vercel: Our hosting provider (vercel.com). Request logs may be retained for up to 24 hours. See Vercel's Privacy Policy.
- Legal obligation: If required by law or court order.
5. Data retention
Attendance records are retained as long as the teacher account exists. Teachers can delete sessions (and their associated records) at any time from the dashboard. Teacher accounts and all associated data can be deleted on request by contacting rivasatechnologies@gmail.com.
6. Student data and consent
Students do not create accounts. When a student submits attendance, they are providing data voluntarily in the context of their educational institution. Teachers using Hazri are responsible for informing students that attendance is being recorded digitally and that location data is captured. By submitting the form, students consent to the collection described in Section 2.
7. Cookies and tracking
Hazri uses only essential session cookies provided by Supabase Auth to keep teachers logged in. We do not use analytics cookies, advertising trackers, or any third-party tracking scripts.
8. Your rights
You have the right to:
- Access the personal data we hold about you.
- Request correction of inaccurate data.
- Request deletion of your account and associated data.
- Object to the processing of your data.
To exercise these rights, email rivasatechnologies@gmail.com. We will respond within 30 days.
9. Security
We take reasonable technical measures to protect your data, including encrypted connections (HTTPS), server-side validation, and Row Level Security on our database so teachers can only access their own data. No system is completely secure — please use a strong, unique password for your account.
10. Changes to this policy
We may update this Privacy Policy. The "Last updated" date at the top of this page will reflect any changes. Continued use of the Service after changes constitutes acceptance.
