# Privacy Policy for HAT Prep HEC
Effective date: 10 October 2026
HAT Prep HEC ("the app") is a study app for the HEC Higher Education Aptitude Test (HAT), published by Furqan Ali ("I", "me"). This policy explains what information the app uses and why. If you have a question, write to faroo450@gmail.com.
## 1. Information the app uses
**Study data on your phone.** Your answers, mock test results, bookmarks, streak and settings are stored on your phone so the app works offline.
**Guest use (no sign-in).** The app creates an anonymous ID for your install (through Firebase Authentication). It is not linked to your name or email.
**Sign in with Google (optional).** If you choose to sign in, the app receives your Google account name and email address. They are used to show your name in the app, to restore your progress on a new phone, and so the developer can recognise you when you ask for help or are given a free upgrade.
**Backup of your progress (only if you sign in).** Your answer history, mock test results and bookmarks are saved online in my Firebase database, under your account, and can be restored when you sign in on another phone.
**Messages you send to me.** If you use "Ask us" or "Report a problem", your message, the optional name you type, the question you report, and a device notification token (so I can reply to you) are stored.
**Usage numbers.** The app records the last day it was opened and the app version for each install, and counts how many times each question was answered and answered wrongly (without linking those counts to you). I use this to improve questions and to know how many people use the app.
**Ads and device data.** The app shows ads from Google AdMob. AdMob may collect your device's advertising ID, IP address, and similar device information to show and measure ads. See Google's policy at https://policies.google.com/privacy. You can reset or delete your advertising ID in your phone's settings.
**Purchases.** If you buy Pro, the payment is handled by Google Play. I only learn that the purchase was made; I never see your payment details.
## 2. Services that receive data
- Google Firebase (Authentication, Cloud Firestore, Cloud Messaging) stores the online data described above.
- Google AdMob shows ads.
- Google Play Billing handles purchases.
- Google Sign-In handles sign-in.
I do not sell your personal information, and I do not share it with anyone other than these service providers.
## 3. Notifications
The app can send a study reminder and announcements, and a notice when I reply to your message. You can turn notifications off in your phone's settings or in the app.
## 4. Keeping and deleting your data
- Data on your phone: use "Reset progress" in Settings, or uninstall the app, to delete it.
- Online data (backup, messages, name and email): email faroo450@gmail.com from the address you used, asking for deletion, and I will delete it. Backups and messages are kept until you ask for deletion or the app is shut down.
## 5. Children
The app is meant for students preparing for a university entrance test and is not directed at children under 13. I do not knowingly collect personal information from children under 13. If you think a child has given me personal information, please email me and I will delete it.
## 6. Security
Data is sent over encrypted connections and stored with Google Firebase. No system is perfectly secure, but I take reasonable care to protect it.
## 7. Changes to this policy
If I change this policy, I will update the date above. Continuing to use the app after a change means you accept the updated policy.
