About CBSE Science 10
Thirteen chapters. Five units. Eighty marks. CBSE Science 10 turns the whole Class 10 Science syllabus into something you can actually revise from — on the bus, the night before, or whenever five minutes opens up.
Every chapter is built the same way, around four tools you switch between with a tap: Notes to read, Cards to drill, Tricks to remember, and Quiz to test yourself. Open a chapter and you get concise revision notes written to the CBSE 2025-26 syllabus, a deck of flip flashcards, a set of memory mnemonics, and a bank of 30+ exam-style questions with a full explanation behind every answer.
No account, no sign-up, nothing to load. All thirteen chapters ship inside the app and work completely offline — from Chemical Reactions all the way to Our Environment.
Free to download with two full chapters — Chemical Reactions and Equations, and Life Processes — unlocked for everyone. A single $5.99 in-app purchase unlocks the remaining eleven chapters and removes ads. One payment, no subscription, ever.
The Syllabus, in Five Units
CBSE Class 10 Science is examined out of 80 marks across five units. CBSE Science 10 mirrors that exactly — each unit colour-coded, each chapter ready to drill. Chapters marked FREE are unlocked for everyone.

Revision Notes
Concise, exam-focused notes for all 13 chapters, written to the CBSE 2025-26 syllabus — clear headings, bullet points, and clean tables you can scan fast.
Flashcard Decks
Tap to flip. Every chapter has a Cards deck of question-and-answer flashcards — mark each one “Got it” or “Still learning” as you work through it.
Memory Tricks
The Tricks tab collects mnemonics for the facts that never stick — OIL RIG, state-symbol orders, reaction types — each with a short explanation.
Practice Quizzes
Pick your session size — Quick (10), Standard (20), or Full (35). Every question is multiple-choice with a worked explanation the moment you answer.
Exam-Style Questions
30+ questions per chapter, graded Easy to Hard, modelled on the kind of MCQs that turn up in the CBSE Class 10 board exam.
Two Chapters Free
Chemical Reactions and Equations and Life Processes are unlocked for everyone — try every tool on a full chapter before you decide to buy.
Works Fully Offline
Every chapter is bundled inside the app. No account, no sign-in, and no internet needed once it’s installed — revise anywhere.
One-Time Unlock
A single $5.99 purchase opens the other eleven chapters and removes the ads — for good. No subscription, no auto-renewal, no recurring charge.

Privacy Policy
Last updated: May 2026
1. Introduction
This Privacy Policy describes how CBSE Science 10 ("the App," "we," "our," or "us") handles information. The App is a study aid for the CBSE Class 10 Science syllabus — notes, flashcards, mnemonics, and quizzes — for iPhone and iPad.
We respect your privacy. This policy explains what the App does, and does not do, with information on your device.
2. Information We Collect
We do not collect any personally identifiable information. CBSE Science 10 does not require an account, does not ask for your name or email, and does not transmit any personal data to our servers (we don’t run any).
- No sign-in, account, or registration.
- No location, contacts, microphone, camera, or photo-library access.
- No first-party analytics or crash-reporting SDKs.
- Your study progress — chapters read, quiz scores, flashcard status — and your unlock entitlement are stored locally on your device only.
3. Advertising (Free Version)
The free version of CBSE Science 10 shows a banner advertisement served by Google AdMob on the Home and Notes screens. AdMob may collect a limited set of identifiers (such as the iOS Identifier for Advertisers, IDFA) and basic device and ad-interaction data in order to show ads and measure their performance.
Before any tracking-based ads can be shown, we present Apple’s App Tracking Transparency prompt. If you choose Ask App Not to Track, AdMob will only serve non-personalised ads, and the IDFA is not shared.
For details on AdMob’s data practices, please review Google’s privacy policy at https://policies.google.com/privacy.
4. In-App Purchase
The Unlock all chapters in-app purchase is processed entirely by Apple via StoreKit. We do not see or store your payment details. Your purchase entitlement is verified through Apple’s receipt, stored locally on your device, and restored on demand via Restore Purchase.
5. Data Sharing
We do not sell, rent, or otherwise share user data. The only third-party data flow is from Google AdMob in the free version, as described above. Unlocking the App removes the banner ad and that data flow entirely.
6. Children’s Privacy
The App is a study aid intended for Class 10 students and is not directed at children under 13. We do not knowingly collect personal information from children, and the App collects no personal information from anyone.
7. Changes to This Privacy Policy
We may update this Privacy Policy periodically. Any updates will be reflected on this page with a new "Last updated" date.
