Data deletion instructions

1. Disconnect Meta (Facebook) in your Meta account

You can remove our app’s access to your Meta account at any time:

1. While logged into Facebook, open Facebook Settings → Apps and Websites.
2. Find this app in the list and choose Remove.
3. For Business integrations, use Meta Business Suite / Business Settings to review partners and connected assets, and revoke access where offered.

Meta’s interfaces change occasionally; if the exact menu names differ, use Meta’s help center and search for “remove app access” or “business integrations”.

2. Disconnect inside Nanostack

If your Nanostack account has an Integrations, Connected accounts, or similar section, open it and disconnect Meta or any other provider you no longer want linked. That stops new data sync from that connection.

3. Request deletion of data we hold

To ask us to delete personal information associated with your account:

Email us

Please include:

• Subject line: Data deletion request
• The email address you use with Nanostack (and company name, if applicable)
• A short description of what you want removed (for example: account, campaign content, integration tokens)

We will confirm receipt and process verifiable requests within a reasonable time, subject to exceptions allowed by law (for example retaining certain billing or security records).

4. Meta Data Deletion callback (developers)

If you are configuring a Meta app, Meta may also ask for a Data Deletion Request URL (callback). That is a separate technical endpoint we implement in our backend to acknowledge signed deletion requests from Meta—not the same as this public instructions page. Use this page’s URL for user-facing deletion instructions where Meta’s form asks for it.
