Last Updated: December 2025

This Privacy Policy describes how Stillo ("we," "our," or "us") collects, uses, and protects information when you use our mobile application ("App"). By using Stillo, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

1.1 App Usage Data

We collect anonymous information about how you use Stillo, including:

• Focus session duration and completion status
• Frequency of app usage
• Features you interact with

This data helps us improve the app's functionality and user experience. All usage data is anonymized and cannot be used to identify you personally.

1.2 App Performance Data

To ensure Stillo runs smoothly and to fix issues, we collect:

• Crash logs and error reports
• Performance metrics (app responsiveness, loading times)

This information is collected automatically and helps us identify and resolve technical issues.

1.3 Device Information

We collect limited, non-personal device information, including:

• Operating system version (e.g., Android version)
• Device model and manufacturer
• App version

This information is used to ensure compatibility and optimize the app for different devices.

1.4 Analytics Data

We use Google Firebase Analytics to collect anonymous usage statistics. This service helps us understand how users interact with Stillo, which features are most popular, and how we can improve the app. All analytics data is aggregated and anonymized.

2. Information We Do NOT Collect

Stillo does not collect the following types of information:

• Your name or personal identification
• Email address
• Phone number
• Location data or GPS coordinates
• Contacts or address book information
• Photos, videos, or other media files
• Payment information or financial data
• Biometric data

We do not require account creation or registration to use Stillo. If you choose to use OAuth login (e.g., Google Sign-In), authentication is handled by the third-party provider, and we do not store your login credentials.

3. How We Use Your Information

The information we collect is used solely for the following purposes:

• App Improvement: To understand how users interact with Stillo and enhance features
• Bug Fixes: To identify, diagnose, and resolve technical issues and crashes
• Performance Optimization: To ensure the app runs efficiently on different devices
• User Experience: To provide a better, more personalized experience

We do not sell, rent, or share your information with third parties for marketing or advertising purposes.

4. Third-Party Services

4.1 Google Firebase

Stillo uses Google Firebase services, which may collect and process information:

• Firebase Analytics: Collects anonymous usage statistics to help us understand app usage patterns
• Firebase Crashlytics: Collects crash reports and error logs to help us fix bugs

These services are provided by Google LLC and are subject to Google's Privacy Policy. You can learn more about how Google uses data at https://policies.google.com/privacy.

Firebase data is stored on Google's servers and is subject to Google's data security measures. We do not have direct access to personally identifiable information through these services.

5. App Permissions

Stillo may request the following permissions on your device:

• Notifications (Optional): To send you reminders and alerts about your focus sessions. You can disable this permission at any time in your device settings.
• Foreground Service: To keep the focus timer running in the background when you switch to other apps. This is essential for the app's core functionality.
• Wake Lock: To keep your device screen active during focus sessions, preventing the screen from turning off while you're using the timer.

All permissions are requested only when necessary for Stillo's functionality. You can revoke permissions at any time through your device settings, though this may affect certain features.

6. Data Storage and Security

Stillo stores data locally on your device. We do not store personal data on our servers. All focus session data and app preferences are stored securely on your device.

We implement reasonable security measures to protect the information we collect. However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.

7. Children's Privacy

Stillo is not intended for children under the age of 18. We do not knowingly collect personal information from children under 18. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately, and we will delete such information from our records.

If we become aware that we have collected personal information from a child under 18 without verification of parental consent, we will take steps to remove that information from our servers.

8. Your Rights and Choices

You have the following rights regarding your information:

• Stop Data Collection: You can stop all data collection by uninstalling Stillo from your device. Uninstalling the app will remove all locally stored data.
• Disable Analytics: You can opt out of Firebase Analytics by adjusting your device's advertising settings or by uninstalling the app.
• Manage Permissions: You can manage app permissions at any time through your device's settings menu.

Since we do not collect personally identifiable information and do not require account creation, there is no account to delete or personal data to request removal of.

9. Data Retention

We retain anonymous analytics and crash data for as long as necessary to improve the app and fix issues. This data is automatically deleted after a reasonable period or when it is no longer needed for these purposes.

Data stored locally on your device (such as focus session history) remains on your device until you uninstall the app or clear the app's data.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top of this policy.

You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.

11. Compliance with Google Play Policies

This Privacy Policy is designed to comply with Google Play Developer Policy requirements, including:

• Transparency about data collection and use
• Clear disclosure of third-party services
• Information about user rights and choices
• Children's privacy protections

12. International Users

If you are using Stillo from outside the United States, please be aware that information we collect may be transferred to and stored on servers located in the United States or other countries. By using Stillo, you consent to the transfer of information to countries outside your country of residence, which may have different data protection rules than your country.
