Privacy Policy

Last updated: 10 October 2026 · Applies to the SF Prep website and the SF Prep Android app

This policy explains what personal data SF Prep collects, why we collect it, who we share it with, how long we keep it and the choices you have. SF Prep is run by Dial N Search Private Limited (“we”, “us”).

In short: we collect only what we need to sign you in and save your learning. We do not sell your personal data. We never see your card or UPI details. You can ask us to delete your account at any time.

1. Information we collect

Type	What it includes	When we collect it
Sign-in	Your WhatsApp phone number and the sign-in message you send to our number (the code, the time and the message ID).	When you send the `LOGIN…` code on WhatsApp.
Profile	Full name, date of birth, gender, and when you accepted our Terms and this policy.	On your first sign-in.
Learning activity	Your answers, tests, DPPs, results, time taken, bookmarks, saved sets, chosen exams or books, language preference, the questions you report, the study XP, streak and leaderboard badges your tests earn, the challenges you share, and your study reminder time.	While you use SF Prep after signing in.
School	The school, class and section you belong to, if you join a school with its code or your school adds you. For teachers who ask for a school portal: the school's name and details you send.	When you join a school or ask for a portal.
Telegram	If you use our Telegram bot (@sfprep_bot): your Telegram chat ID, name, username and language, and your quiz answers.	When you start the bot.
Purchases	Google Play order number, plan, purchase and renewal dates, and subscription status. Payment details are handled by Google Play; we never see your card, UPI or bank details.	If you buy an ad-free plan.
Android app	A push notification token (Firebase Cloud Messaging), if you allow notifications. Crash reports (Firebase Crashlytics) such as device model, Android version, app version and what the app was doing when it crashed.	When you use the app.
Technical logs	IP address, browser or device type, pages requested, date and time, and error details.	Whenever you visit, to run and secure the service.

You can read our free notes, current affairs and GK without an account. In that case we do not know who you are; we only keep the technical logs above, and Google may use cookies for ads as explained in section 6.

We do not ask for your email, address, Aadhaar, photos, contacts or location.

2. Cookies and local storage

Cookies are small files your browser stores for a website. We use a few of our own cookies and the browser's local storage to make SF Prep work:

Name	Purpose
`sfprep_auth`	Keeps you signed in. Encrypted, and cannot be read by page scripts.
`sfprep_login_client`	Links the sign-in code shown on the screen to this browser, so you are signed in on the right device.
Session cookie	Keeps a test you are taking in progress.
`sf_qlang`	Remembers the language you chose for questions and notes.
Local storage	Saves test answers on your device so they are not lost if the connection drops, and remembers small display choices such as the notes font.

These are needed for SF Prep to work, so they cannot be switched off inside SF Prep. If you block them in your browser, signing in and tests will not work. Google's advertising cookies are described in section 6.

3. How we use your information

To sign you in, keep your session secure and stop misuse of sign-in codes.
To save your progress and show your results, analysis, bookmarks and library.
To personalise practice to the exams or books you chose.
To give you the ad-free plan you bought and check its status with Google Play.
To show your streak, XP, leaderboards, badges and challenge boards.
To send app notifications, including study reminders, if you allowed them.
To review question reports and fix mistakes.
To find and fix bugs, and to protect SF Prep from scraping, fraud and attacks.
To answer your messages and requests.
To follow the law and respond to lawful requests.

We do not use your data to make automated decisions that have legal or similar effects on you.

4. Why we are allowed to use it

We use your personal data on the basis of the consent you give when you create your account and accept this policy, and where it is needed to provide the service you asked for, to keep it secure, or to comply with the law. You can withdraw your consent at any time by asking us to delete your account; this does not affect what we did before you withdrew it.

6. Advertising

Some pages show ads served by Google: Google AdSense on the website and Google AdMob in the Android app. No ads are shown on sign-in or profile pages, while you take a test, or to users with an active ad-free plan.

Google and its partners use cookies (website) and the device advertising ID (app) to show and measure ads, including ads based on your earlier visits to this and other websites.
Where the law requires it (for example in the EEA and the UK), we ask for your consent before personalised ads are shown.
You can turn off personalised ads at Google Ad Settings, and reset or delete the advertising ID in your phone's Android settings.
How Google uses this data: policies.google.com/technologies/partner-sites.
Some users aged 13 or over may be invited to an optional SF Coins Wallet, where they can choose to watch rewarded ads for in-app coins. Google tells us when such an ad was watched (with your account number and an ad reference, not your name or phone); we keep this with your coin history. Coins have no money value.

7. Children

SF Prep is used by school students, and you must be at least 5 years old to create an account. If you are under 18, a parent or guardian should read this policy, agree to it for you and supervise your use of SF Prep. A parent or guardian can ask us to see or delete their child's data by writing to us from the contact details below.

8. How long we keep it

Data	How long
Account, profile and learning activity	While your account is active. Deleted within 30 days of a confirmed deletion request.
Ad-free plan purchase records	As long as tax and accounting laws require, even after the account is deleted.
Technical logs and sign-in messages	Only as long as needed to run, secure and debug the service.
Crash reports	As set by Firebase Crashlytics.

9. Security

We take reasonable steps to protect your data, including:

HTTPS encryption for all traffic between your device and SF Prep;
an encrypted sign-in cookie, and one-time sign-in codes that expire;
checking that sign-in messages really come from WhatsApp;
rate limits that block automated abuse of sign-in and tests;
access to personal data only for authorised team members who need it.

No system is completely secure. If we learn of a data breach that affects you, we will inform you and the authorities as the law requires.

10. Your rights and choices

See your data: your profile, results and bookmarks are in the app. You can also ask us for a summary of the personal data we hold about you.
Correct it: ask us to correct wrong or incomplete details.

Withdraw consent: stop using SF Prep and ask us to delete your account.
Notifications: turn them off at any time in your phone's settings.
