Privacy Policy
Last updated: February 28, 2026
Market Post Pro ("we", "us", or "our") operates the website www.marketpostpro.com and the Market Post Pro Chrome Extension (collectively, the "Service"). This Privacy Policy explains how we collect, use, and protect your information when you use our Service.
By using Market Post Pro, you agree to the collection and use of information in accordance with this policy. If you do not agree, please discontinue use of the Service.
1. Information We Collect
Account Information
When you sign in with Google, we receive your name, email address, and profile picture from Google. We use this information solely to create and manage your account within Market Post Pro. We do not receive or store your Google password.
Vehicle Listing Data
When you use the Service to scrape vehicle listings, we collect and store the vehicle information you choose to save — including vehicle details (year, make, model, trim, price, mileage, VIN), images, and any descriptions or notes you add. This data is associated with your account and is used to power your listing history and posting features.
Usage Data
We may collect anonymized usage information such as pages visited, features used, and general interaction patterns. This data is used to improve the Service and does not identify you personally.
Chrome Extension
The Market Post Pro Chrome Extension accesses the content of dealer vehicle listing pages you visit in order to extract vehicle information at your request. The extension does not collect browsing history, does not run on pages you have not explicitly chosen to scrape, and does not transmit any data without your action.
2. How We Use Your Information
We use the information we collect to:
- Authenticate your identity and maintain your session
- Store and display your saved vehicle listings
- Generate AI-powered vehicle descriptions on your request
- Provide the Facebook Marketplace auto-fill feature
- Improve and maintain the Service
- Respond to support requests
We do not sell, rent, or share your personal information with third parties for marketing purposes.
3. Google Sign-In
Market Post Pro uses Google OAuth 2.0 for authentication. When you sign in with Google, we request access only to your basic profile information (name, email address, and profile picture). We do not request access to your Gmail, Google Drive, Google Calendar, or any other Google services.
Your use of Google Sign-In is also governed by Google's Privacy Policy.
4. Data Storage and Security
Your data is stored on secure servers. We implement reasonable technical and organizational measures to protect your information against unauthorized access, alteration, disclosure, or destruction. Session authentication is handled via signed HTTP-only cookies.
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.
5. Data Retention
We retain your account information and saved vehicle listings for as long as your account is active. You may delete individual listings at any time from your history. To request deletion of your account and all associated data, please contact us at the email address below.
6. Third-Party Services
Market Post Pro uses the following third-party services to operate:
- Google OAuth — for authentication
- AI language models — for generating vehicle descriptions (vehicle data is sent to the model; no personal account data is included)
These services have their own privacy policies. We are not responsible for the practices of third-party services.
7. Children's Privacy
Market Post Pro is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us and we will promptly delete it.
8. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any significant changes by updating the "Last updated" date at the top of this page. Continued use of the Service after changes constitutes acceptance of the updated policy.
