MarketCraft ("the app") is an educational app that teaches personal finance and how the Indian stock market works. This policy explains what happens to your information when you use it.
Short version: everything stays on your phone unless you choose to sign in with Google. Then only your learning progress is copied to our cloud, and you can delete it any time. A certificate becomes public only if you tap “Add a verify link”.
The app saves the following locally on your phone (Android app storage). Unless you sign in (section 2), none of it is sent to us or anyone else:
The first name you type during onboarding (you can change it in Profile)
Learning progress: lessons completed, coins, streaks, badges, quiz and game results
Questions you answered wrongly, so the Revise feature can bring them back on later days
My Money Plan answers, if you fill them in: monthly take-home pay, monthly expenses, savings, costly debt, age and whether you have dependents, health cover or term cover
Stock checks you save in “Check a stock yourself”: the company name and the numbers you type
Inputs you type into calculators such as Meet Future You and Tax Check; these are not saved unless they come from your Money Plan
Your Trade World practice account: the virtual money balance, pretend trades, pending orders, watchlist, price alerts, chart lines and trade journal. Trade World uses made-up companies and made-up prices with virtual money only; nothing is real money and nothing is sent to a broker
Your invite code (a random 6-character code) and the invite and thank-you codes you have used, so each reward is given only once
Your "Investor DNA" (built from your choices in the practice games)
Strategies you build and save in the Strategy Lab
Settings such as language, appearance, daily reminder on/off and its time, and the “Thought for the day” quote on/off
You can delete all of this at any time with Profile → Settings → Reset progress (Trade World also has Start fresh in Add money), or by uninstalling the app.
Signing in is optional. You can tap Not now and use every feature without an account. If you tap Continue with Google (during setup, on the first screen, or in Profile):
What we receive from Google: your Google account's email address, name and a unique account ID. We do not receive your Google password, contacts or anything else in your Google account.
What is copied to the cloud: your learning progress (the first name you typed, lessons completed, coins, streaks, badges, quiz and game results, questions to revise, Investor DNA, saved Strategy Lab strategies, your invite code and app settings).
What is never copied: your My Money Plan answers, any holdings you entered, your saved stock checks and your Trade World practice account. They stay only on your phone.
Where it is stored: Google Firebase (Firebase Authentication and Cloud Firestore), run by Google as our service provider, in the Mumbai (asia-south1) region. Data is encrypted in transit (HTTPS) and at rest. Security rules let only your own signed-in account read or change your backup.
Why: only to restore your progress if you change or reset your phone. It is not used for advertising, analytics or profiling, and it is not sold or shared with anyone else.
How long: until you delete it (see “Delete your account” below).
Signing out only stops backups; it does not delete the saved copy.
When you finish a learning path, you can tap Add a verify link on your certificate (you need to be signed in). This publishes a small public record so others can check that the certificate is real: the name on the certificate, the path’s title, the number of lessons and steps, the date, the certificate number and your account ID. Anyone who has the certificate number or link can see it at marketcraft-4942.web.app/verify. If you never tap the button, nothing about your certificate leaves your phone. The record is removed when you delete your account.
The app does not open, read or upload any files from your phone. When you share a certificate or result, you choose the app to share it with (for example WhatsApp or LinkedIn); MarketCraft does not post anything for you.
Mutual fund NAV history: when you use the fund labs, the app downloads public AMFI NAV data from the free service mfapi.in. The request contains only the fund name you type in the search box or the fund's scheme code. It contains no personal information. mfapi.in may log standard technical details such as your IP address, under its own policies.
App updates: the app checks Expo's update service (expo.dev) for new versions of its content and code. That request includes technical details such as the app version, runtime version and platform (Android). It contains no personal information.
Sign-in, backup and verify links (only if you use them): Google sign-in and Firebase (googleapis.com), as described in section 2.
Links to other websites: some screens have “look it up” links to NSE, BSE, Screener, Moneycontrol, AMFI, Value Research, Morningstar and the Income Tax Department. They open in your phone’s browser, outside the app. If you typed a company name in “Check a stock yourself”, the link is a Google search for that name on the chosen site. Those websites’ own privacy policies apply, and MarketCraft is not affiliated with them.
The free app shows ads from Google AdMob: a banner at the bottom of the Explore and Charts tabs, and short video ads only when you choose “Watch a short ad” to earn coins. There are no ads inside lessons.
To show ads, limit how often you see them and prevent fraud, Google's ad SDK collects your device's advertising ID, IP address (which gives an approximate location), app and device information, and how you interact with ads. Google processes this as described in its policy: policies.google.com/technologies/partner-sites. We don't receive your personal information from Google.
You can reset your advertising ID or turn off personalised ads in your phone's Settings → Google → Ads (on some phones Settings → Privacy → Ads). The ads are meant for adults; we use AdMob's controls to block gambling and similar categories.
The app has no analytics SDK. An account is optional.
When you send a challenge (Market Duel, Life Simulator, Stock Check or a Trade World challenge) or an invite, the message contains a short code and a link to marketcraft-4942.web.app. A challenge code holds only the game or day number and the scores; an invite code holds only random letters. No name, account or personal data is in any code. Our website is hosted on Firebase Hosting (Google), which may log standard technical details such as IP address and browser type to run and protect the service. The website has no ads, cookies for tracking, or analytics.
The Listen button reads lesson text using your phone's built-in text-to-speech voice. The text is processed by your phone's speech engine; the app does not record audio or send it anywhere.
If you turn on the daily reminder, the app schedules a local notification on your phone. No push server is used, and no notification token is sent anywhere.
Notifications: only if you turn on the daily reminder.
The app does not request location, contacts, camera, microphone or SMS permissions.
MarketCraft is intended for users aged 18 and over. It is not directed at children.
MarketCraft is for education only. It is not registered with SEBI as an investment adviser or research analyst, and nothing in the app is a recommendation to buy, sell or hold any security. “Check a stock yourself” only compares numbers you type with general rules of thumb; it never says buy, sell or avoid. No live market data is used. Real data shown in the app is public and at least 3 months old.
If this policy changes, the updated version will be posted at this address with a new "Last updated" date.
Under India's Digital Personal Data Protection Act, 2023 you can ask to see, correct or delete your data in our cloud, or withdraw consent (sign out and delete your account). Write to marketcraftsupport@gmail.com with any question or complaint about this policy; we reply within 7 days.
You only have a MarketCraft account if you signed in with Google. To delete your account and all data we hold:
In the app: open Profile → Settings → Delete my account & backup and confirm with your Google account. Your account, cloud backup and any public certificate records are deleted straight away.
Without the app: email marketcraftsupport@gmail.com from the Google account you used, with the subject “Delete my account”. We delete your account, backup and certificate records within 7 days and confirm by email.
What is deleted: your MarketCraft account (email, name, account ID), your cloud backup and any verify-link certificate records. Nothing is kept afterwards. Progress saved on your own phone is not affected; remove it with Profile → Settings → Reset progress or by uninstalling the app.
