Privacy Policy for Form Autofill Pro

Last updated: December 27, 2025

This Privacy Policy describes how Form Autofill Pro ("we", "us", or "our") handles your information when you use our Firefox browser extension.

1. Data Collection and Storage

Form Autofill Pro is designed with privacy as a priority.

• Local Storage Only: All data you save within the extension (such as form profiles, names, emails, addresses, and other form field values) is stored exclusively on your device using the Firefox Storage API (browser.storage.local).
• No External Transmission: We do not transmit, sync, upload, or back up your data to any external servers, cloud services, analytics platforms, or third-party services. Your data never leaves your browser environment.
• No Data Collection: We do not collect any personal information, usage statistics, telemetry, or analytics data about you or your browsing habits.

2. How We Use Your Information

The information you save in the extension is used strictly for the following purposes:
- To populate form fields on websites you visit, upon your explicit request.
- To display your saved profiles within the extension's interface.
- To provide local notifications about form field detection and filling results.

All processing happens locally on your device. No data is sent to us or any third party.

3. Permissions

The extension requests the following permissions to function:

• Storage: To save your form profiles locally on your device.
• ActiveTab: To detect and interact with form fields on the current webpage you are visiting.
• Scripting: To inject content scripts that enable form detection and filling functionality.
• Host Permissions (<all_urls>): To allow the extension to work on any website you choose to use it on.

These permissions are used exclusively for the core functionality of capturing and filling forms. We do not use them to track your browsing or collect any data.

4. Sensitive Data Protection

For sensitive form fields (such as passwords, credit card numbers, CPF, SSN, or other personal identifiers):
- Data is encrypted using AES-GCM 256-bit encryption before being stored locally.
- Encryption keys are derived from your browser's fingerprint and never leave your device.
- We cannot access or decrypt your sensitive data as we have no access to your device or encryption keys.

5. Third-Party Sharing

We do not sell, trade, rent, or otherwise transfer your information to any outside parties. Since we do not collect or transmit your data, we have no data to share with anyone.

6. Backup and Export

The extension allows you to:
- Export your data to a JSON file for backup purposes.
- Import previously exported data back into the extension.

These backup files are created locally on your device. You have full control over where these files are stored and who has access to them.

7. Security

We rely on the security mechanisms provided by the Mozilla Firefox browser and your operating system to protect the data stored locally:
- Data is stored using Firefox's secure storage APIs.
- Sensitive fields are encrypted with industry-standard AES-GCM encryption.
- We recommend keeping your browser and operating system updated to ensure maximum security.

8. Children's Privacy

This extension does not knowingly collect or solicit information from anyone under the age of 13. If you are under 13, please do not use this extension.

9. Your Rights

Since all data is stored locally on your device, you have complete control:
- Access: You can view all your saved data within the extension interface.
- Delete: You can delete any or all profiles at any time.
- Export: You can export your data for backup or migration purposes.
- Uninstall: Uninstalling the extension will remove all locally stored data.

10. Changes to This Privacy Policy

We may update our Privacy Policy from time to time to reflect changes in functionality or legal requirements. We will notify you of any changes by:
- Posting the new Privacy Policy on this page.
- Updating the "Last updated" date.
- Notifying users through the extension update notes.

Your continued use of the extension after any changes indicates your acceptance of the updated Privacy Policy.

11. Data Retention

Your data is retained locally on your device for as long as you choose to keep it. We do not have access to your data and cannot delete it remotely. To remove all data:
- Delete individual profiles within the extension, or
- Uninstall the extension from Firefox.

12. Compliance

This extension complies with:
- GDPR (General Data Protection Regulation) - No personal data collection or processing.
