Zoom’s iOS App Shares Data with Facebook Regardless of User’s Account Status

A recent discovery reveals that Zoom, a popular video conferencing app, sends user data to Facebook even when a user does not have a Facebook account. Businesses might switch to Google Meets.

With the COVID-19 pandemic leading to a significant increase in remote work and virtual communication, the video conferencing app Zoom has rapidly gained popularity. However, it has recently been discovered that Zoom’s iOS app sends user data to Facebook even when a user does not have a Facebook account. This raises concerns over the privacy and security of the app, especially since users are often unaware of this data sharing.

What Kind of Data is Shared with Facebook?

Upon opening the app, Zoom’s iOS app automatically sends information to Facebook about the user’s device, network, time zone, city, and more. Additionally, it shares a unique advertiser identifier, which enables companies to target the user with personalized ads. This data sharing occurs even if the user has not logged into the app using a Facebook account.

Unique Advertiser Identifier

A unique advertiser identifier is an alphanumeric string assigned to a user’s device, enabling advertisers to track the user across various apps and websites. This identifier helps companies target the user with personalized ads based on their interests and behavior. Although users can reset their identifier or opt-out of targeted advertising, most are unaware of this option or its implications.

Zoom’s Privacy Policy

Zoom’s privacy policy does not explicitly mention this data sharing with Facebook. While it states that the company collects information about a user’s device, operating system, and network, it does not mention sharing such data with third parties like Facebook. This lack of transparency can be particularly concerning for users who are conscious of their online privacy.

Changes in Zoom’s Privacy Policy

Zoom has made recent changes to its privacy policy, stating that it no longer sends data to Facebook when users open its iOS app. However, these changes only came to light after the data-sharing practice was publicly disclosed.

Security and Privacy Concerns

The fact that Zoom shares user data with Facebook without explicit consent raises several security and privacy concerns. Users may be unaware that their data is being shared with a third party, which can lead to a sense of betrayal and mistrust in the app’s security measures. Additionally, this data sharing may be illegal in some jurisdictions under data protection laws.

Legal Ramifications

The European Union’s General Data Protection Regulation (GDPR) requires companies to obtain explicit consent from users before sharing their data with third parties. If Zoom is found to be in violation of these regulations, it could face significant fines and legal repercussions.

Recommendations for Users

Users who are concerned about their privacy and security when using Zoom’s iOS app should consider taking the following steps:

  1. Update to the latest version of the app: Zoom claims to have stopped sharing data with Facebook in recent updates, so users should ensure they have the latest version installed.
  2. Review and adjust privacy settings: Users should review their privacy settings on both Zoom and Facebook, adjusting them to limit data sharing and targeted advertising.
  3. Be cautious when using social media login options: When signing up for new apps, users should be cautious when using social media accounts to log in, as this can lead to unwanted data sharing.
  4. Consider alternative video conferencing apps: If privacy and security are a top priority, users may want to explore alternative video conferencing apps with more transparent privacy policies and practices.


Zoom’s iOS app sharing user data with Facebook, even when the user does not have a Facebook account, raises serious privacy and security concerns. Users should remain vigilant about their privacy settings and be cautious when using social media logins for various apps. While Zoom has updated its privacy policy and claims to have stopped sharing data with Facebook, it is essential for users to stay informed about the privacy practices of the apps they use and consider alternative solutions if necessary. By taking a proactive approach to their online privacy, users can better protect themselves from unwanted data sharing and potential security risks.
