GymMathics Privacy Policy EN
Effective date: September 1, 2026 Last updated: September 1, 2026
This Privacy Policy explains how the GymMathics app ("App", "we")
handles your information. The App is developed by Novrian
("Developer") and is available on the Google Play Store under the
package name com.novrian.gymmathics.
By downloading and using the App, you agree to the practices described in this policy. If you do not agree, please stop using the App.
1. Quick Summary
- GymMathics is a basic math practice app.
- We do not operate our own server. All of your practice data (player name, level progress, XP, and session history) is stored only locally on your device.
- We do not require you to create an account, and we do not collect your real name, email address, phone number, contacts, precise location, photos, or other identity data.
- The App shows ads through Google AdMob and supports in-app purchases through Google Play Billing. These third-party services may collect certain data as described below.
2. Information We Process
2.1 Information you provide yourself (stored locally)
| Data | Example | Purpose | Storage location |
|---|---|---|---|
| Player name | The nickname you freely type on the Profile page | Greeting you in the app and displaying it on result cards | A file in the App's internal storage on your device |
| Progress & achievements | Levels passed, stars, XP, rank | Saving your game progress | A file in the App's internal storage |
| Session history | Operation, mode/level, score, duration, stars, session date | Displaying your practice history | A file in the App's internal storage |
| "Pro" status | A flag indicating whether ads have been disabled via purchase | Enabling the ad-free version | A file in the App's internal storage |
Data in this section is never sent to the Developer and never uploaded to any server by us. The player name is entirely up to you; we recommend not using your full legal name or other sensitive information.
This data is deleted when you uninstall the App or clear the App's data through your device settings (see Section 8).
2.2 Information collected automatically by third-party services
a. Google AdMob (advertising)
The App shows banner and interstitial ads from Google AdMob. To serve and measure ads, Google and its advertising partners may collect and process data such as:
- Your device's Advertising ID (Google Ad ID);
- IP address and approximate IP-based location (e.g., country/city);
- Device and system information (model, OS version, language, carrier, network type);
- Ad interactions (ads viewed, tapped, and view duration);
- Identifiers used for fraud prevention and ad frequency capping.
This data is collected directly by Google through the Google Mobile Ads SDK embedded in the App. Its processing is governed by Google's Privacy Policy and how Google uses information from sites or apps that use its services.
b. Google Play Billing (in-app purchases)
If you purchase the "Pro" product (remove ads), the transaction is processed entirely by Google Play. We do not receive or store your card number, payment data, or identity. The App only asks Google Play whether the currently signed-in account owns the "Pro" product, then stores that status flag locally. Ownership is tied to your Google Play account by Google, so the purchase can be restored on another device using the same account. Payment processing is governed by the Google Play Terms of Service.
c. Google Play Services
Distribution, updates, integrity verification, and platform-level crash reporting may be handled by Google Play in accordance with Google's policies.
We do not embed any other third-party analytics, behavioral tracking, or crash-reporting SDKs (e.g., Firebase Analytics, Crashlytics, Facebook SDK) in the App.
3. Basis and Purpose of Processing
We and our third-party service providers process the information above for the following purposes:
- Running the App's core functionality (storing your progress and history on-device);
- Displaying ads to fund the App for free-tier users;
- Processing and restoring "Pro" purchases;
- Maintaining security and preventing abuse and ad fraud;
- Complying with applicable legal obligations.
4. Sharing and Saving Result Images
The App has "Share Result" and "Download Result" features on the results page.
- Download Result saves a PNG image of the result card to your
device gallery, in the
Pictures/GymMathicsalbum. The image is only saved on your device. - Share Result creates a temporary image and opens Android's built-in share menu. You fully choose the destination (messaging app, social media, email, etc.). Once the image leaves GymMathics, its handling is governed by the destination app's privacy policy.
We do not upload result images to any server.
5. App Permissions
| Permission | Reason for use |
|---|---|
INTERNET |
Loading ads from Google AdMob and communicating with Google Play Billing |
ACCESS_NETWORK_STATE |
Checking network availability before requesting an ad |
WRITE_EXTERNAL_STORAGE (Android 9 / API 28 and below only) |
Saving result images to the gallery on older Android versions; on Android 10 and above, the save-to-gallery feature uses scoped storage and does not require this permission |
The App does not request location, camera, microphone, contacts, phone, SMS, or broad file-access permissions.
6. Third-Party Services
The App relies on the following services. We encourage you to read each one's privacy policy:
- Google AdMob / Google Mobile Ads — https://policies.google.com/privacy and https://support.google.com/admob/answer/6128543
- Google Play Billing / Google Play — https://policies.google.com/privacy and https://play.google.com/about/play-terms/
7. Personalized Ads and Your Choices
- You can limit or reset your Advertising ID via Device Settings → Google → Ads (or Settings → Privacy → Ads). There you can also choose "Delete advertising ID" or "Opt out of Ads Personalization".
- In regions where required (e.g., the EU/EEA, UK), the App may show a Google consent dialog before personalized ads are served.
- You can remove ads entirely by purchasing the "Pro" product within the App.
8. Data Storage, Retention, and Deletion
- The data described in Section 2.1 is stored on your device for as long as the App is installed.
- To delete all of the App's local data, you can:
- Go to Device Settings → Apps → GymMathics → Storage → Clear data, or
- Uninstall the App.
- Data collected by Google (Section 2.2) is stored and deleted according to Google's retention policies. Requests regarding that data can be made through your Google Account's privacy controls at https://myaccount.google.com/.
9. Children's Privacy
GymMathics is intended for a general audience wanting to practice basic arithmetic skills. We do not knowingly collect personal data from children. Because the App does not ask for a real name, email, or other identity data, and all game data is stored locally, the App does not build a user profile on our side.
If you are a parent or guardian and believe your child has provided personal data to a third-party service through the App, please contact us at the address in Section 12, and use the Advertising ID controls in Section 7 to limit ad data collection.
10. Security
Local data is stored in the App's private storage area, which on standard Android devices cannot be accessed by other apps. However, no method of electronic storage is completely secure; we cannot guarantee absolute security, particularly on rooted or modified devices.
11. Changes to This Policy
We may update this Privacy Policy from time to time. The latest version will always be available on this page, with an updated "Last updated" date. We will make reasonable efforts to notify you of material changes through the App's release notes.
