1. INTRODUCTION
This Privacy Policy explains how Grammar Check Assistant ("we", "our", "us", or "the App") collects, uses, and protects information when you use our mobile application. By installing and using the App, you agree to the practices described in this policy. If you do not agree, please do not use the App.
2. INFORMATION WE COLLECT
We have designed Grammar Check Assistant to collect as little personal information as possible. The App does not require you to create an account, and we do not ask for your name, email address, phone number, or any other directly identifying information.
2.1 Text you submit for grammar checking
When you use the grammar-checking feature, the text you enter, paste, share into the App, or load from a file is sent over the internet to the LanguageTool API (https://api.languagetool.org/v2/) so that grammar, spelling, and style suggestions can be returned to you. This text is transmitted only for the purpose of performing the grammar check and is not stored on our own servers. LanguageTool's handling of this text is governed by their own privacy policy, available at https://languagetool.org/legal/privacy.
2.2 Images and media files (optional)
If you choose to import text from images stored on your device, the App requests the READ_MEDIA_IMAGES permission (on Android 13+) or READ_EXTERNAL_STORAGE permission (on Android 12 and below). Images are processed on your device and are not uploaded to our servers. Only text that you explicitly choose to check is transmitted to LanguageTool.
2.3 Information stored locally on your device
The App stores the following information only on your device, never on our servers:
- Your grammar-check history (text you have checked and the suggestions returned), stored in a local Room database.
- Your app preferences (such as theme, language settings, and notification preferences), stored using Android DataStore.
You can delete this data at any time by clearing the App's data in Android settings or by uninstalling the App.
2.4 Advertising information
The App displays advertisements served by Google AdMob. Google and its partners may collect and process certain information through the AdMob SDK to serve personalized or non-personalized ads, including:
- Advertising ID (a resettable identifier assigned by your device).
- Approximate (non-precise) location derived from IP address.
- Device information (model, OS version, language, crash data).
- Ad interaction data (impressions, clicks).
Google's use of advertising data is governed by the Google Privacy Policy: https://policies.google.com/privacy. You can reset or limit your Advertising ID at any time in your Android device settings under "Privacy" or "Google" > "Ads".
2.5 Network and device information
The App uses the INTERNET and ACCESS_NETWORK_STATE permissions to send requests to the LanguageTool API and to determine whether a network connection is available. Your IP address may be visible to LanguageTool and to Google AdMob as part of normal network communication.
3. PERMISSIONS USED AND WHY
- INTERNET and ACCESS_NETWORK_STATE: required to send text to the LanguageTool API for grammar checking and to serve ads.
- POST_NOTIFICATIONS: used to show optional notifications, such as reminders or check-complete alerts.
- VIBRATE: used for haptic feedback inside the App.
- READ_MEDIA_IMAGES (Android 13+) / READ_EXTERNAL_STORAGE (Android 12 and below): used only if you choose to import an image or text file from your device.
4. HOW WE USE INFORMATION
We use the information described above only to:
- Provide the grammar, spelling, and style checking features of the App.
- Save your history and preferences locally for your convenience.
- Display advertisements that keep the App free to use.
- Diagnose crashes and improve stability (through standard Google Play services).
We do not sell your personal information. We do not use your text for training artificial intelligence models. We do not profile users beyond what is required to serve ads via Google AdMob.
5. THIRD-PARTY SERVICES
The App integrates the following third-party services. Each has its own privacy policy:
- LanguageTool (grammar-checking API): https://languagetool.org/legal/privacy
- Google AdMob (advertising): https://policies.google.com/privacy
- Google Play Services: https://policies.google.com/privacy
These providers may process data about you (such as your IP address, device identifiers, and advertising ID) in accordance with their own policies.
6. DATA SECURITY
All network requests made by the App use HTTPS with TLS encryption. Locally stored data is kept in the App's private storage area, which is not accessible to other apps on your device. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
7. DATA RETENTION
- Text sent to LanguageTool is not retained by us. Please consult LanguageTool's privacy policy for details on their retention practices.
- History and preferences stored locally on your device remain until you clear them, clear the App's data, or uninstall the App.
- Advertising data is retained by Google AdMob according to Google's policies.
8. CHILDREN'S PRIVACY
Grammar Check Assistant is not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us at kamilamin046@gmail.com and we will take steps to delete such information.
9. YOUR RIGHTS
Depending on your jurisdiction (for example, under the GDPR in the European Economic Area or the CCPA in California), you may have the right to:
- Access the personal data we hold about you.
- Request correction or deletion of your personal data.
- Object to or restrict certain processing.
- Withdraw consent for personalized advertising.
- Lodge a complaint with a data protection authority.
To exercise these rights, contact us at kamilamin046@gmail.com. Because most of your data is stored only on your device, you can often satisfy these rights directly by clearing the App's data or uninstalling the App.
10. OPTING OUT OF PERSONALIZED ADS
You can opt out of personalized advertising at any time:
- On Android: open Settings > Google > Ads, and enable "Opt out of Ads Personalization" or reset your Advertising ID.
- You may also control your ad preferences at https://adssettings.google.com.
11. INTERNATIONAL DATA TRANSFERS
The third-party services we use (LanguageTool, Google) may process your information on servers located outside your country of residence. By using the App, you consent to such transfers, which are carried out with appropriate safeguards as required by applicable law.
12. CHANGES TO THIS PRIVACY POLICY
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this document. Continued use of the App after changes are posted constitutes your acceptance of the revised policy.
