Grammarly is generally safe to use on Android devices, as it employs strong data encryption and industry-standard security practices. However, because it operates as a custom keyboard, it technically has the ability to read and collect everything you type, including passwords and personal messages. Understanding these permissions helps you make an informed choice about your digital privacy.
Is Grammarly Safe on Android? The Short Answer
If you are wondering whether you can trust this popular writing assistant on your smartphone, the short answer is yes. Millions of users and major tech platforms trust Grammarly.
However, safety means different things to different people. While the app will not intentionally steal your data, using any third-party keyboard requires a certain level of trust. Let’s break down how Grammarly handles your data on Android, what permissions it asks for, and how you can protect your privacy.
How Grammarly Works on Android
To fix your grammar and spelling in real-time across different apps—like Gmail, WhatsApp, and Google Docs—Grammarly runs as an active keyboard service on your Android phone.
When you type, the Grammarly keyboard processes your text to offer suggestions. According to Grammarly’s official privacy policy, the app does not collect sensitive data such as:
- Credit card numbers
- Passwords
- Street addresses
- Phone numbers
What Data Does Grammarly Collect?
To improve its AI and provide writing suggestions, Grammarly does collect certain types of information:
- Text Data: The words and sentences you type (to check for errors).
- Usage Data: How you interact with the app, performance logs, and crash reports.
- Device Information: Your device type, operating system, and unique device identifiers.
Understanding Grammarly Android Permissions
When you install Grammarly from the Google Play Store, the app requests specific permissions to function correctly.
| Permission | Why Grammarly Asks for It | Privacy Implication |
|---|---|---|
| Full Access / Network Access | To send text snippets to Grammarly’s cloud servers for grammar checking. | Your typing leaves your device and goes to secure servers. |
| Vibrate & Sound | To give you haptic feedback while typing on the virtual keyboard. | Completely harmless; local to your device. |
| Show over other apps | To display spelling corrections and floating widget tools over your active apps. | Necessary for the keyboard interface to pop up smoothly. |
The “Access Your Personal Data” Warning Explained
When installing any third-party keyboard on Android, your phone displays a scary warning message stating that the app might be able to collect all the text you type, including personal data like passwords.
This is a standard Android security warning for all custom keyboards (including Gboard and SwiftKey). It does not mean Grammarly is malicious; it simply describes the technical capability required for a keyboard to do its job.
Grammarly Privacy: Pros and Cons
Before deciding to keep or install the app, consider these privacy advantages and drawbacks:
Pros:
- Enterprise-Grade Security: Data is encrypted both in transit (using HTTPS/TLS) and at rest (using AES-256).
- Control Over Personal Data: You can easily delete your Grammarly account and wipe all stored writing data at any time.
- Block Sensitive Fields: Grammarly automatically turns off in fields marked as password inputs or secure login screens.
- SOC 2 Compliance: The company undergoes regular independent audits to verify its security measures.
Cons:
