Free · Made in India · CBSE Classes 6 to 12

Study that earns screen time.
Safety that holds.

Vinaya is one free family app. Your child learns CBSE chapters through animations, quizzes and step-marked long answers, and finished study earns the screen time you choose. You get real control of their phone and PC: remote lock, live location, SOS and app limits.

Vinaya Study: animated velocity–time graph in Class 11 Physics
Vinaya parent dashboard: today's screen time and what needs attention

Why parents love Vinaya

Less fighting about phones. More real learning.

Most parental-control apps only say "no". Vinaya gives your child a reason to say "yes" to study, and gives you the tools to step in when it matters.

Safety when it counts

Lock every device from your phone and see it confirmed ("locked on 2 of 2"). Live location with 30-day history and home/school geofences. A child SOS button, remote ring, low-battery and location-off alerts.

Learning earns screen time

Study apps are free to use; social, video and games burn the daily budget faster. Finish a quiz and ask for bonus minutes — you approve with one tap.

CBSE, made clear

Chapters follow the current NCERT books in the order schools teach, with concept-first explanations, animations and long answers marked the way CBSE marks them.

Free for every family

No subscription, no ads, no "premium" lock on safety. If Vinaya helps you, you can support it later, just like Wikipedia.

Respect, not spying

Vinaya never reads calls, SMS, chats or social messages. You see time, apps, websites and location: what you need to guide, not to snoop. Your child can see the rules too.

How it works

Set up in three steps

  1. 1

    Create your family

    Sign up on the parent dashboard (web, Android or Windows), add your child and their CBSE class.

  2. 2

    Protect their devices

    Install Vinaya Guard on the child's Android phone (quick setup with a code, no factory reset) or run the Windows installer as admin.

  3. 3

    Pair the Study app

    Enter the pairing code in Vinaya Study. Rules, study time and rewards now flow both ways. You approve, they learn.

Concept-first lessons for CBSE Classes 6 to 12, chapter by chapter on the current NCERT syllabus. See what is ready now

Gyaan Isles game New

Every chapter is an island zone. Right answers grow crystals, and real mastery beats the boss. See it

Animated concepts

Step-by-step diagrams you can play, pause and rewind until the idea clicks.

Realistic clips

See a candle melt, water swirl and nails rust in short looping clips, right inside the lesson.

Concept-first physics

Graphs drawn as you read, so slope really means velocity and area really means distance.

Long answers, CBSE-marked CBSE

Write your answer first, then check it against a model marked point by point, the way the board marks.

Practice with feedback

Up to 50 questions a chapter. Get one wrong and see why straight away, with the working.

Revision guides

Key points at the end of every chapter. One-page Class 12 guides are on their way into the app.

Games & rewards

Points for real effort, spent on the extra screen time you agree to.

Hindi Quest Game

Build words from letter blocks, open मात्रा doors and beat the bosses.

Ask a doubt Offline

Stuck on 2x + 3 = 11 or a tricky word? Get the steps at once, even with no internet.

Real animations from the course

These are the exact files the app uses. Pick one:

Animated velocity–time graph
Class 11 Physics · Velocity–time graph: slope and area
Looping clip: a candle burning
Class 7 · Candle burning: physical + chemical change
Looping clip: convection current in water
Class 7 · Convection current
Looping clip: iron nails rusting
Class 7 · Rusting needs air and water
Looping clip: a cork bobbing on ripples
Class 11 · Waves move energy, not the cork

Study, gamified

Gyaan Isles: a world they light up by learning

Every zone is a chapter. Every crystal is a concept mastered. Kids play their way through the syllabus, and you watch the progress.

Build an explorer

Pick skin, hair, outfit and a pet. New outfits unlock by mastering zones. Nothing to buy.

Explore Science Island

All 12 Class 7 Science chapters are zones, from Curiosity Camp to Heat Volcano. Answer right and crystals grow.

Beat the Magma Golem

The boss tests recall, not luck. Crack its armour with right answers, earn the badge, put it on the trophy shelf.

Review that sticks

Due questions return to restore a zone, so concepts come back before they fade.

No chat, ads or purchases

A safe world with no strangers, no shop and nothing to pay for.

Parents see progress

Zones mastered and badges earned show up in your parent app.

Free, forever

Every feature free. For every family.

Vinaya has no ads, no paid tier and doesn't sell data. Safety should never depend on what a family can pay. If Vinaya helps your child, you'll be able to support it with a small, voluntary donation, just like Wikipedia. Children never see donation requests.

Donations are not open yet. Nothing is charged on this site.

Download & verify

Install safely, verify every file

Coming to Google Play by 27 January 2027

Until then, Vinaya installs from our own server. Always download from aavahanam.com, check the fingerprint, then follow the install guide for your phone.

Signing certificate fingerprints

Vinaya Android apps — signing certificate (APK Signature Scheme v2)
All three APKs (vinaya-agent.apk, vinaya-parent.apk, vinaya-study.apk) are signed with the same key.
Subject: CN=DW, OU=DW, O=DW, L=Hyderabad, ST=Telangana, C=IN
Certificate SHA-256: 79:2C:24:E9:1D:C2:C2:8F:EB:F1:72:B8:DA:A8:47:F1:5C:45:D4:96:16:EA:12:83:69:27:34:DE:01:01:12:B0

Verify:  apksigner verify --print-certs vinaya-agent.apk
Android refuses to update an installed Vinaya app with an APK signed by any other key.

How to verify

Windows (PowerShell)
Get-FileHash .\vinaya-windows-x64.zip -Algorithm SHA256
Mac / Linux
sha256sum vinaya-agent.apk
Signing certificate
apksigner verify --print-certs vinaya-agent.apk

The hash must match exactly. Android also refuses updates signed with a different certificate, so a tampered update cannot replace a genuine Vinaya install.

Install guide

Installing on Android, step by step

Your phone warns you because Vinaya isn't on the Play Store yet, not because anything is wrong. Check the file first, then pick your phone.

  1. Verify first

    Compare the SHA-256 and signing fingerprint with the list above. If they match, the file is genuine.

  2. Allow the installer

    Open the APK from Chrome or Files. When asked, allow Install unknown apps for that one app.

  3. Get past Play Protect

    If you see Unsafe app blocked, tap More details, then Install anyway.

FAQ

Questions parents ask

Is Vinaya really free?

Yes. Every study and safety feature is free. There are no ads. Voluntary donations may open later; children never see them.

Does Vinaya read my child's messages or calls?

No. Vinaya never reads calls, SMS, WhatsApp or social media messages. It shows screen time, apps, websites visited and location: enough to guide, not to spy.

Which classes and subjects are covered?

Vinaya is built for CBSE Classes 6 to 12. Classes 7, 11 and 12 are live now, with every subject on the current NCERT syllabus; Classes 6, 8, 9 and 10 are on the way. The chapter list shows exactly what is ready today.

Is Vinaya on the Play Store?

Not yet. It is coming to Google Play by 27 January 2027. Until then, install from aavahanam.com and follow the install guide.

Do I need to factory-reset my child's phone?

No. Quick setup uses a code and the phone's device-admin permission. An optional "Maximum protection" mode uses a factory reset so Vinaya cannot be removed at all.

Does it work on iPhone?

Not for device control, because Apple doesn't allow it. Your child can still use Vinaya Study in the browser on an iPhone or iPad.

What happens if my child removes or bypasses it?

On Android, uninstalling and factory reset are blocked, and turning protection off sends you an alert. On Windows, Vinaya runs as a protected service with a watchdog. A child who knows the device's unlock code can still try; you'll know.

Does the study app need internet?

Chapters download once and then work offline, including Ask a doubt. Progress syncs when the device is back online.

Where is our data stored?

On Vinaya's own server in a dedicated database. Not sold, not shared with advertisers. Location history is kept for 30 days.
