Privacy Policy

Introduction

Welcome to PromptMask. This Privacy Policy describes how PromptMask ("we", "us", or "our") protects your privacy and handles your information when you use our Chrome extension. PromptMask is designed with privacy as its core principle: all data processing occurs locally in your browser, and we do not collect, store, or transmit any personal data to our servers or any third parties.

Definitions

• Personal Data: Any information relating to an identified or identifiable individual, such as your name or email address.
• Processing: Any operation performed on Personal Data, such as collection, storage, use, or deletion.
• Extension: The PromptMask Chrome extension.

Our Privacy Commitment

PromptMask is built to protect your privacy. All personal data you configure in the extension is processed exclusively within your browser. We do not collect, track, or store your data remotely. No information leaves your device at any time.

What Data PromptMask Uses

Personal Data You Provide

You may enter personal data (such as your name, email address, etc.) into PromptMask's settings to be protected. This information is:

• Stored locally using Chrome extension storage
• Used only to generate anonymized prompts before submission
• Never shared, transmitted, or sold

Configuration Data

PromptMask saves:

• Your list of personal data items to protect
• The placeholder formats you’ve configured (e.g., __FIRST_NAME__)

This allows PromptMask to remember your preferences between sessions. All data remains on your device.

How PromptMask Works

1. You configure your personal information and placeholder settings in the extension.
2. When composing a prompt, you use the extension to generate an anonymized version of your prompt before it is submitted to the AI service.
3. The AI chatbot receives only the anonymized version of your message.
4. This process is performed entirely in your browser. No information leaves your device.

Permissions

Storage Permission

Used to:

• Store your privacy settings and personal data mappings
• Retrieve that information when replacing text in prompts

Host Permissions

PromptMask requests access to supported AI chat platforms to provide its functionality.

• Supported AI chat platforms (e.g., popular web-based AI chat services)

These permissions are required to enable local anonymization of your input. PromptMask does not access or interact with other parts of your browser or unrelated websites.

Data Security

We implement technical measures to ensure that all data processed by PromptMask remains on your device and is never transmitted externally. Your configuration and personal data are stored using Chrome's local extension storage, which is only accessible to you and the extension.

No Data Sharing, Selling, or Tracking

• We do not sell, rent, or transfer user data to third parties.
• We do not use your data for any purpose outside of PromptMask’s core functionality.
• We do not use or transfer your data for credit decisions or lending.
• We do not track your activity or usage.

Your Rights

Since PromptMask does not collect or process your data outside your device, you retain full control over your information. You may delete or modify your data at any time through the extension settings. No data is accessible to us or any third party.

Children's Privacy

PromptMask is not intended for use by children under the age of 13. We do not knowingly collect or process any personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to remove such information.
