User Data Deletion

Overview

Facebook requires apps that access user data to provide a clear way for users to request deletion of their data. You must provide either: (A) Data Deletion Instructions that explain how users remove the app and request deletion, or (B) a Data Deletion Callback URL that Facebook can call to trigger automated deletion. Implementing a callback and/or clear instructions is mandatory for app review and to move the app to live use. :contentReference[oaicite:1]{index=1}

How users can request deletion

Choose one of the following methods to request deletion of your personal data stored by this app.

1. Email request (manual)

Send an email to info@genius-tech-eg.com with the subject Delete My App Data. Include:

Your Facebook name
Email used with the app (if any)
Any additional info to help identify your account (user id, profile link)

We will verify your identity and remove all data linked to your account. Typical processing time: within 48 hours after verification unless legal retention applies.

2. Remove the app via Facebook

Remove the app from your Facebook account (Settings → Apps and Websites → find this app → Remove). Facebook will notify us and, if a Data Deletion Callback is configured, it will call our endpoint to begin automated deletion. :contentReference[oaicite:2]{index=2}

Important: If you removed the app and Facebook invoked our callback, you will receive a confirmation code and link (if available) to check the deletion status.

What we will delete

We delete all personal data associated with your account collected or generated by this app, including Facebook-provided profile information and any app-specific records, unless we are legally required to retain certain records (e.g., for tax or regulatory reasons). After deletion we’ll remove identifiers and purge backups according to our retention policy.

Contact & Verification

For manual deletion requests or questions: info@genius-tech-eg.com. Provide enough details to identify your account. We may ask for additional verification to prevent unauthorized deletions.

Deletion status page (optional)

When the Data Deletion Callback is used, our system returns a status URL so users can track progress. Example status page path you can implement:

https://genius-tech-eg.com/deletion-status?request_id=ABC123

This page should show request creation time, current state (pending / in progress / completed), and the confirmation_code.

Developer: Data Deletion Callback (must-haves)

HTTPS endpoint — the callback URL must use HTTPS and be publicly reachable. No HTTP. :contentReference[oaicite:3]{index=3}
Registered in App Dashboard — add the callback URL in your app settings under Facebook Login → Data Deletion Requests. :contentReference[oaicite:4]{index=4}
Return JSON — when Facebook calls your callback, respond with JSON containing at least url (status URL) and confirmation_code (alphanumeric). Example format below. :contentReference[oaicite:5]{index=5}
Verify requests — validate that the request originated from Facebook (signed_request or signature verification) and authenticate accordingly.
Process promptly — start deletion immediately or schedule it; keep the user informed via the status URL.

Expected JSON response

{ “url”: “https://genius-tech-eg.com/deletion-status?request_id=ABC123”, “confirmation_code”: “XG7H2-9P” }

Example callback endpoint (Node.js / Express)

This is a minimal example — adapt to your auth and verification flow.

// POST /data-deletion-callback app.post(‘/data-deletion-callback’, express.urlencoded({extended:true}), (req,res)=>{ // 1) Validate request signature / signed_request from Facebook (implement verification) // 2) Extract facebook user id or app-scoped id from payload // 3) Schedule or perform deletion for that user in your DB // 4) Generate request_id & confirmation_code and status URL const requestId = ‘REQ-‘+Date.now(); const confirmationCode = ‘CD-‘+Math.random().toString(36).slice(2,10).toUpperCase(); const statusUrl = `https://genius-tech-eg.com/deletion-status?request_id=${requestId}`; // Respond with JSON (Facebook requires this structure) res.json({ url: statusUrl, confirmation_code: confirmationCode }); });

Testing & verification

Send a simulated POST to your endpoint and ensure the JSON response is reachable by Facebook.
Check logs to confirm signature validation and mapping to user records.

Why this matters: Facebook will check that your app provides a working deletion flow or clear instructions during review. Proper implementation avoids rejection or disabling of the app. :contentReference[oaicite:6]{index=6}

Recordkeeping & audit

Log deletion requests, verification steps, and final actions taken. Maintain an audit trail in case Facebook or regulators request proof of deletion.

FAQ

Q: How long until my data is gone?
A: We aim to complete deletion within 48 hours of verification unless legal retention applies.
Q: Will backups be deleted?
