1. What stays on the teacher's phone
- Sheet photos. All OMR reading happens on the device itself. Photos are not uploaded to us or to any cloud AI service.
- Your device code & license. A random code identifying your phone (for your paid pass) is stored locally and in our license records.
- App lock PIN/biometric settings. Never leave the device.
2. What we store, and where
- Test results — roll number, marks, correct/wrong/blank counts, and any flags — stored in Google Firebase Firestore under your teacher or school account, so your data survives a lost phone and syncs to the school dashboard.
- Student roster — the roll numbers and names you type in, so results and parent reports can show names instead of bare numbers. Stored under your own account, never shared with anyone.
- Test setup — test title, class, subject, question count and your answer key.
- Pass & payment records — your plan, issue/expiry dates and the Razorpay payment reference, so we can verify purchases and restore your pass when you change phones.
- Trial records — the name and WhatsApp number you enter when starting the free trial, so the trial stays one-per-person and we know who we are supporting.
- School registration requests — the details you type into the registration form (school name, city, contact person, phone, email).
3. What we deliberately do NOT collect
- Student addresses, photos, or parent contact numbers. We hold only what the teacher types — roll number and name — nothing more.
- Your WhatsApp contacts or messages. Sharing results opens your WhatsApp with a ready message; you pick the chat yourself. We never read or send anything on your behalf.
- Location, advertising identifiers, or browsing behaviour. The app contains no ads and no third-party trackers.
4. Who processes data for us
We use Google Firebase (authentication, database and hosting) and Google Cloud, with servers located in India (asia-south1). Payments are processed inside the app by Razorpay — we receive only the payment confirmation and reference, never your card/UPI credentials or bank details.
5. Children's data
OMR Mitra is used by teachers in classrooms, so we designed for children's privacy from day one: the only student data we hold is what the teacher types — roll number, name and marks — stored under the teacher's own account and used only to prepare results and reports for parents. It is never shared with, or sold to, any third party. Sheet photos, which may contain handwriting, never leave the teacher's phone.
6. Data retention & deletion
- Ask us any time (WhatsApp or support@omrmitra.in) and we will delete your account data and license records.
- Uninstalling the app removes everything stored on the phone, including sheet photos and results not synced to the cloud.
- School accounts: your school's admin can request export or deletion of the school's entire dataset.
7. Security
- Paid passes are locked to one phone using Ed25519 cryptographic signatures — copying the app to another device does not carry your license.
- All traffic to our cloud uses TLS encryption.
- School data is isolated per school at the database-rules level; one school can never read another's records.
8. Changes to this policy
If we change this policy we will update the date above and announce it in the app. Continued use after a change means you accept the updated policy.
