Privacy policy

Last updated: 9 November 2026

Who we are

Unity Publication and Educational Services ("Unity Publication", "we", "us"), Vadodara, Gujarat, publishes books and video courses and runs the Tarkit MCQ practice app (earlier called the Unity Publication app) and the website unitypublication.org for Gujarat competitive exams, in Gujarati and English. We decide why and how your personal information is used, so we are responsible for it. By creating an account and using the app or website you agree to this policy. You can withdraw that agreement at any time (see "Your rights").

What we collect and why

• Login and account: your mobile number (or e-mail, if you log in by e-mail), and your name and e-mail if you give them. The login code is kept only in scrambled form and for a short time. Why: to log you in and secure your account.
• Your phone: the make and model, and a device ID. The app makes the device ID on your phone by scrambling Android's own ID with a one-way method (SHA-256); we never receive the Android ID itself. Why: our rule of one mobile number on one phone, and to stop account sharing.
• Your IP address, when you ask for or enter a login code, place an order or pay. Why: to stop abuse and repeated attempts.
• Practice and progress: the questions shown to you and your answers (choice, right or wrong, time taken, language, date), mock tests and scores, mistakes notebook, study log and streak, planner settings (exam date, daily goal, reminder time), and any question you report. Why: to run the practice features, show your progress and suggestions, and apply your plan's daily limit. We do not use this for advertising and give it to no one else.
• Your profile: the exam(s) you choose, preparation stage, strong and weak subjects, daily study time and app language.
• Plans and payments: your plan, its dates, price and discount, your referral code and rewards, and Razorpay or Google Play order and payment numbers. We never see or store your card, UPI or bank details.
• Books, courses and e-books: for a printed book, your name, mobile number, address, city and pin code; for courses and e-books, your access, the lesson being played, and e-book reading counts.
• Problems with the app: crash reports (app version, phone model, Android version, screen, error text, with phone numbers, e-mails and tokens masked). Our server's timing logs hold no personal details.
• Our contact list: if you earlier contacted us, bought from us or were a member of our old website, we may hold your name, number or e-mail in our own list.
• On your phone: your login token, language and app-lock PIN (stored scrambled) sit in the phone's secure storage. Fingerprint or face unlock is handled by Android; we never receive it. The optional daily study reminder is made on your phone; our server sends nothing for it. The camera is used only when you tap scan on a book code. The app checks on the phone whether it is rooted or an emulator, and reads the Google Play install link once, only to open the book or lesson that link pointed to.

Why we use your data

Because you asked for the service, because you consented when you signed up, because the law requires us to keep certain records, and to prevent misuse such as account sharing and repeated free trials.

Messages from us

• Service messages (login code, account-deletion code) go to your mobile number by WhatsApp, and to your e-mail if WhatsApp does not work. You cannot switch these off while you use the account.
• Reminders and offers about your own plan or trial (for example, plan ending soon, trial day 5 and 7) may be sent by WhatsApp or e-mail, a few per plan, between 9 am and 9 pm. Each has a link to stop them. If the link has expired, write to us and we will stop them.

Who we share it with

We do not sell your personal information and do not use it for third-party advertising. These providers receive only what they need:

• Hostinger: hosts our website, database and backups.
• Razorpay: takes payments on the website.
• Google (Google Play Billing): takes payments made inside the Android app and tells us only that a purchase was made, its product and its order number.
• Meta (WhatsApp Business): delivers WhatsApp messages to your number.
• Bunny: delivers course videos.
• Telegram: we send the delivery details of paid printed-book orders (name, address, mobile number) and short alerts to our private owner chat.
• Courier companies: your name, address and mobile number, to deliver a book.
• Your browser contacts Google (fonts) and YouTube (free preview videos) when you open those pages of our website.

We may also give information when the law or a court requires it.

Outside India

Some of these providers run servers outside India, so your information may be processed or stored outside India. We choose well-known providers and share only what is needed.

If you delete your account

In the app, open your profile and choose "Delete my account and data"; a 6-digit code (valid 10 minutes) is sent to your mobile number. You can also do it without the app at unitypublication.org/delete-account, with a code sent to your mobile number on WhatsApp, or to your e-mail if you log in with e-mail.

• Erased: login sessions and devices, practice answers and notebook, study log, planner and reminders, mock tests, profile and exam choices, reports, referral code and coupons, course and e-book access, login and deletion codes, and the name, e-mail, mobile number and device on your account.
• Kept, with your name, e-mail, mobile number and IP address removed: order and payment records (amount, date, item, Razorpay or Google Play numbers), as tax and accounting law requires, for up to 8 years. A printed-book order that is paid but not yet shipped is kept until it ships; after that we remove the name and address by hand. A used sticker code stays marked as used, with only an account number.
• Kept, scrambled: so that deleting and signing up again does not give a second free trial, we keep one-way scrambled codes (keyed hashes) of your mobile number, e-mail and phone's device ID, with the date your first trial began, for 400 days (about 13 months). The device code is saved when your phone is first linked to your account; the number and e-mail codes when you delete. For 30 days after you delete, the same kind of code also remembers which exam you had chosen and the day you deleted, so that deleting and signing up again cannot be used to change the exam you chose on the Free plan or to reset the same day's daily limit. We cannot read a number, e-mail or ID back from them; they only let our system recognise the same one returning. They are still personal data and we treat them so.
• Backups: we keep 14 daily database backups, so deleted data may sit in an old copy for up to 14 days before it is overwritten. Our hosting company's backups follow its own schedule. We use backups only to restore after a failure.
• Others: Razorpay, Google, Meta and Telegram keep their own records under their own policies; our deletion cannot erase those. A paid plan, course or e-book is lost on deletion, with no refund; auto-renew is cancelled first.

How long we keep other data

Login codes: 7 days after they expire. Logged-out sign-ins: 30 days. Security logs with IP addresses: up to 12 months. Crash reports and timing logs: 30 days. Account and learning data: until you delete the account.

Children

The service is made for adult exam aspirants. We do not ask your age at sign-up. If you are under 18, please use it only with a parent's or guardian's permission; they may write to us to see, correct or delete your data. We show no advertising and do not track you for advertising. If we learn that a child's account was opened without a parent's permission, we will delete it on request.

Security

We use reasonable safeguards: login codes stored scrambled, limits on attempts, password and authenticator-protected admin access, encrypted connections in the app, no card data on our servers, and daily backups. No system is completely safe, so keep your codes and PIN private. If a breach affects your data, we will inform you and the authorities as the law requires.

Your rights

You may ask us to show what we hold about you, correct it, erase it or withdraw your consent, and you may complain. Use in-app deletion, or write or call us. We acknowledge within 2 working days and aim to resolve within 30 days. Where the law makes us keep a record, we will tell you why. Withdrawing consent may mean we can no longer give you the service.
