Do we pay anything when we preorder?

No. A preorder is a request. Our team contacts you, confirms the details and sends a final quote. You pay only after you confirm.

What does the ৳99 monthly subscription include?

All premium features of Nirvar, MyTube and OI Browser on that student's tablet, plus access to the institution web console and the Android control app. The first 3 months are free.

What happens if we stop the subscription?

The tablet keeps working as a tablet. Premium features such as advanced rules, curated MyTube content and console management stop until the subscription is renewed.

Can students remove Nirvar or get around the rules?

On Dishari Tab, Nirvar is part of the system. It cannot be uninstalled, the safe-internet and VPN settings are locked, and in our testing it blocked 16 of 17 common bypass tricks.

Can parents see their child's usage too?

Yes. Nirvar has a parent mode, so parents can see usage and approve requests alongside the institution, if your institution allows it.

Do the rules still work without internet?

Yes. Rules are stored and enforced on the tablet, so limits, schedules and bedtime work with or without a connection.

How long does delivery take?

It depends on order size and stock. You choose a preferred delivery window in the preorder form and we confirm the timeline with your quote. We deliver to all 8 divisions.

Is there a warranty and support?

Yes. Every tablet has a manufacturer warranty, and your institution gets a dedicated support contact. Details are included in your quote.

Why Dishari

A tablet is a door. You decide what's behind it.

Ordinary tablets arrive open to everything. Dishari arrives already set up for learning, and it stays that way.

Even stronger on Dishari Tab

Because Nirvar is part of the tablet's system, it can do more than any app from a store.

Zero setup

Tablets arrive enrolled and configured for your institution.

Apps paused, not deleted

Blocked apps are suspended at system level, so they cannot open at all.

DNS & VPN locked

Network safety settings cannot be changed on the tablet.

Cannot be uninstalled

Nirvar is part of the system, not an app students can remove.

Bedtime & study hours

Whole-device schedules for nights, exams and class time.

Managed settings

Factory reset, developer options and account changes are controlled.
