At Amooz App Studio, we believe you should always be in control of your data. This page explains how to delete the data associated with your use of our apps, MathStudy and English Exam Prep. For both apps, you can delete your data in a few seconds from inside the app, or by sending us an email.
Scroll down to the section for the app you use: MathStudy comes first, followed by English Exam Prep. The contact details at the bottom apply to both apps.
MathStudy
If you’d like to delete the data associated with your use of MathStudy, you can do so in just a few seconds using either of the methods below.
Method 1: Delete from Within the App (Fastest)
This is the quickest way to delete your data. Everything is removed immediately, with no waiting or back-and-forth.
- Open MathStudy on your Android device.
- Tap the Settings tab at the top-right of the Home screen.
- Scroll down to the Data & Privacy section.
- Tap Delete My Data.
- Confirm the deletion when prompted.
That’s it. Your data is deleted right away.
Method 2: Email Us a Deletion Request
If you’ve already uninstalled MathStudy or you’re unable to access the in-app option for any reason, just send us an email and we’ll take care of it for you.
Email: support@amoozstudio.app | Subject line: Delete My Data
To help us locate your data quickly, please include in your email:
- The approximate date you first installed MathStudy
- The email address linked to your Google Play purchase (only if you had an active premium subscription)
- Any other detail that might help us identify your data
We will process your request within 30 days and confirm by email once it’s complete. Most requests are handled within a few business days.
What Gets Deleted
When you request deletion, the following data is permanently removed:
- Your scan history and AI Tutor sessions
- Your lifetime usage statistics (total scans, app opens, features used)
- Your local app preferences
- Your anonymous device identifier
- Subscription tier records linked to your device
What Is Kept to Prevent Abuse
A small set of free-tier scan counters (daily and monthly) are kept after deletion to prevent abuse of the free tier — without them, a user could repeatedly delete their data to reset their scan limits.
These counters:
- Contain no personally identifiable information
- Reset automatically over time (daily counters reset every 24 hours; monthly counters reset at the start of each month)
- Are only used to enforce the 3-scans-per-day and 10-scans-per-month free-tier limit
If you upgrade to a Premium subscription, these counters become irrelevant and are no longer applied to your account.
What Is Not Automatically Deleted
A couple of things you should know about:
- Your Google Play subscription. Deleting your data does not cancel an active subscription. To cancel, please visit https://play.google.com/store/account/subscriptions or open the Google Play Store on your phone, tap your profile icon, and go to Payments & subscriptions → Subscriptions.
- Records we are required to keep by law. A small number of records, such as proof of past purchases for tax purposes, may be retained as required by applicable laws. These records are kept securely and are not used for any other purpose.
English Exam Prep
If you’d like to delete the data associated with your use of English Exam Prep, you can do so in just a few seconds using either of the methods below. English Exam Prep has no accounts, so most of your data (essays, transcripts, scores, and results) is stored only on your own phone, and you are in control of it.
Method 1: Delete from Within the App (Fastest)
This is the quickest way to delete your data. Everything on your phone is removed immediately, with no waiting or back-and-forth.
- Open English Exam Prep on your Android device.
- Tap the Settings tab in the bottom bar.
- Scroll down if needed and tap Delete My Data.
- Confirm the deletion when prompted.
That’s it. Your saved data is deleted right away, and the app restarts at its welcome screen, as if freshly installed.
Method 2: Email Us a Deletion Request
If you’ve already uninstalled English Exam Prep, you’re unable to access the in-app option for any reason, or you want us to delete the usage and crash data we hold under your app’s anonymous installation ID, just send us an email and we’ll take care of it for you.
Email: support@amoozstudio.app | Subject line: Delete My Data
To help us locate your data quickly, please include in your email:
- The name of the app (English Exam Prep)
- The approximate date you first installed it, and your phone model
- The email address linked to your Google Play purchase (only if you had an active premium subscription)
- Any other detail that might help us identify your data, such as a Firebase Installation ID if you can find one
We will process your request within 30 days and confirm by email once it’s complete. Most requests are handled within a few business days.
What Gets Deleted
When you use the in-app Delete My Data button, the following is permanently removed from your phone:
- Every saved Practice and Mock Exam attempt, including your essays and written answers, speech transcripts, scores, AI feedback, and estimated band scores, across every feature
- Your onboarding setting, so the app treats your phone as new again
When you send us an email request, we also delete the usage events and crash reports we hold under your app’s anonymous installation ID, as far as we are able to identify them.
Uninstalling the app also removes everything stored on your phone.
What Is Kept to Prevent Abuse
A small set of free-tier usage counters for the app’s AI-powered practice features are kept after deletion to prevent abuse of the free tier. Without them, a user could repeatedly delete their data to reset their usage limits.
These counters:
- Contain no personally identifiable information
- Reset automatically over time
- Are only used to enforce the free-tier limits
If you upgrade to a Premium subscription, these counters become irrelevant and are no longer applied.
What Is Not Automatically Deleted
A few things you should know about:
- Your Google Play subscription. Deleting your data does not cancel an active subscription. To cancel, please visit https://play.google.com/store/account/subscriptions or open the Google Play Store on your phone, tap your profile icon, and go to Payments & subscriptions → Subscriptions.
- Copies held by our AI providers. When you use an AI feature, your writing or recording is processed by Anthropic (written feedback) or OpenAI (speech-to-text). These providers may keep a copy for a limited time, up to 30 days, and delete it on their own schedule. We cannot delete it earlier.
- Your latest voice recording file. The app keeps only your most recent recording as a temporary file in its private storage, and “Delete My Data” does not remove it. It is replaced by your next recording. To remove it yourself, clear the app’s cache: on your phone, open Settings → Apps → English Exam Prep → Storage → Clear cache, or uninstall the app.
- Your Dark Mode setting. We treat this as a device preference, not personal data.
- Records we are required to keep by law. A small number of records, such as proof of past purchases for tax purposes, may be retained as required by applicable laws. These records are kept securely and are not used for any other purpose.
