Google API Services User Data Policy Compliance
Document King Scanner's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Data Protection Mechanisms for Sensitive Data
- Data Encryption in Transit: All sensitive data, including Google OAuth tokens, personal identifiers, and scanned documents, transmitted between your device, our application, and Google's APIs is securely encrypted in transit using industry-standard HTTPS/TLS protocols.
- Secure Storage & Minimum Retention: We do not store your scanned documents, PDF files, or image data on our servers. All file operations are directed entirely to your personal Google Drive. The only data we store in our secure, encrypted database relates directly to your authentication session (Name, Email, Profile Picture, and OAuth Tokens) which are strictly required to communicate with Google APIs on your behalf.
- Access Control & Human Intervention: We strictly request the minimum required scopes necessary for the app's core functionality. No human personnel, developer, or third party has access to your private documents, files inside your Google Drive, or your sensitive Google Account authentication data.
- Data Deletion & Revocation: You retain full ownership and control over your data. You can delete your files at any time directly from your Google Drive. Furthermore, when you use the "Log Out" function within Document King Scanner, our system automatically revokes your Google OAuth token via Google's revocation API and instantly deletes your user record and session data from our database.
1. Information We Collect and Access (Google OAuth Permissions)
When you authenticate with Document King Scanner via Google OAuth, we strictly request the following permissions to provide our service. We access this information natively through Google's API:
- Email Address Visibility: To securely identify your primary Google Account email address.
- Basic Profile Access: To see your personal info, including any personal info you've made publicly available (such as your name and profile picture) to personalize your session.
- OpenID Connect: To associate you securely with your personal info on Google.
- App-Specific Drive Access: To strictly see, edit, create, and delete ONLY the specific Google Drive files you use and create with this app (i.e., the "Document King Scanner" folder). We cannot see or access your other Drive files.
- AI Quota Management: To use generative AI models utilizing your personal quota, ensuring fair usage of AI resources.
- Sensitive Permission (AI Semantic Retrieval): To view, query, edit, and manage the content you uploaded to the AI Semantic Retriever. We specifically use this to process document images in real-time for automated edge detection and text extraction (OCR).
2. How We Use Your Information (Limited Use)
In strict adherence to the Limited Use policy, we use the accessed data exclusively for the following purposes:
- Authentication: Logging you into the app via Google OAuth.
- Document Storage: Creating PDFs based on your scans and saving them directly into the newly created "Document King Scanner" folder in your Google Drive.
- Real-time AI Processing: Sending temporary image chunks to the Google Gemini API strictly to detect document boundaries. These images are processed in-memory and instantly discarded; they are never permanently stored, used for advertising, or used to train AI models.
3. Data Sharing and Third Parties
Your privacy is absolute. We do not sell, trade, rent, or transfer your personally identifiable information, OAuth tokens, or scanned documents to any third parties for any reason.
Data is only transferred securely over HTTPS to Google's official APIs (Google Drive API for file storage, and Google Generative Language API for edge detection). We do not use third-party analytics providers that intercept or read your sensitive Google user data.
4. Your Rights and Data Revocation
As a user, you hold complete control over your data:
- Immediate Data Wipe: By clicking "Log Out" in the Document King Scanner app, our backend servers make a direct API call to Google to revoke our application's access to your account, followed by a complete deletion of your user profile and database records from our system.
- Manual Revocation: You can independently revoke our application's access at any time by visiting your Google Account settings page at myaccount.google.com/permissions.
5. Advertisements
Currently, Document King Scanner does not display any third-party advertisements within the application. We are committed to providing a clean, distraction-free scanning experience. However, Document King Scanner reserves the right to introduce advertisements or sponsorships in the future to support the ongoing development and maintenance of the application. If this policy changes, any integrated ad networks will strictly adhere to our data privacy principles and will not be granted access to your sensitive Google Account data or your scanned documents.
6. Changes to This Privacy Policy
* This Privacy Policy is subject to change at any time by Document King Scanner. We reserve the right to update, modify, or completely revise this policy without prior explicit notice to reflect changes in our practices, technology, Google API regulations, or legal requirements. Your continued use of the Document King Scanner application following any changes constitutes your acceptance of the revised Privacy Policy. We encourage you to review this page periodically for any updates.
