Data Deletion Instructions & Data Policy
1. Introduction
This Data Deletion Policy explains how users can request the deletion of their data collected through our application via Facebook Login and Facebook APIs.
Our application respects user privacy and complies with the Facebook Platform Terms, Meta Developer Policies, and applicable data protection regulations. Users have the right to request access, correction, and deletion of their personal information at any time.
2. Information We Collect via Facebook
When users log in to our application using Facebook Login, we may collect the following information, depending on the permissions granted:
- Public profile information (name, profile picture, Facebook ID)

- Any additional permissions explicitly approved by the user
We do not collect or store sensitive personal data beyond what is required for authentication and application functionality.
All collected information is used solely for:
- User authentication and account creation
- Providing core application services
- Improving user experience
We do not sell, rent, or share user data with third parties for marketing purposes.
3. How Users Can Request Data Deletion
Users may request deletion of their personal data at any time through one of the following methods:
Method 1: In-App Account Deletion
Users can delete their account directly inside the application by:
- Logging into their account
- Navigating to Settings
- Selecting Delete Account
- Confirming the deletion request
Once confirmed, all associated user data stored in our system will be permanently deleted within 7 business days.
Method 2: Facebook App Removal
Users can also remove the application directly from Facebook:
- Go to Facebook Settings
- Click on Apps and Websites
- Select our application
- Click Remove
After removing the app, Facebook will notify our system through a Data Deletion Callback (if configured). Upon receiving this request, we will delete all associated user data within 7 business days.
Method 3: Direct Data Deletion Request
Users may also request data deletion by contacting us via email:
Email: tuananh.ngta@gmail.com
Subject line: “Facebook Data Deletion Request”
To process the request, users must include:
- Their full name
- The email address associated with their Facebook account
- Their Facebook User ID (if available)
We will confirm the request within 3 business days and complete deletion within 7 business days.
4. Data Deletion Process
When a deletion request is received:
- The user's account will be deactivated immediately.
- All personal data will be permanently removed from our production database.
- Any tokens, session data, and Facebook access tokens will be revoked and deleted.
- Backup data containing user information will be deleted during the next scheduled backup cycle (no longer than 30 days).
After deletion is complete, the user will receive a confirmation email.
Deleted data cannot be restored.
5. Data Retention
We retain user data only as long as necessary to:
- Provide our services
- Maintain security and prevent fraud
- Comply with legal obligations
If a user becomes inactive but does not request deletion, we may retain minimal account data unless legally required to remove it.
If legally required, certain transactional or compliance records may be retained for a limited period.
6. Data Security
We implement appropriate technical and organizational measures to protect user data, including:
- Encrypted data transmission (HTTPS)
- Secure server infrastructure
- Restricted database access
- Role-based access control
- Regular security monitoring
Only authorized personnel have access to user data.
7. Facebook Data Deletion Callback URL
If applicable, our application implements a Facebook Data Deletion Callback URL in compliance with Facebook requirements.
When Facebook sends a deletion request via the callback:
- We verify the signed request
- We identify the corresponding user
- We delete all associated data
- We return a confirmation code or status URL as required
8. Changes to This Policy
We reserve the right to update this Data Deletion Policy as necessary to comply with legal, technical, or business changes.
