LinkedIn is a popular social media platform used by professionals to network and find job opportunities. While it offers many benefits, there are some privacy concerns users should be aware of when using LinkedIn.
Data Collection
LinkedIn collects a significant amount of data about its users including:
- Profile information – name, photo, education, work history, skills, interests, etc.
- Connections/contacts
- Group memberships
- Job searching and application activity
- Browsing and clickstream data
- Location data
- Device information
While some of this data is needed to provide core services, the extent of data collection is quite broad. LinkedIn states this data helps provide a personalized experience and relevant suggestions to users.
Data Sharing
LinkedIn shares user data with:
- Third party services – LinkedIn uses third party apps, services, and advertising partners. Information may be passed to these partners.
- LinkedIn Corporation – Data may be shared across LinkedIn products (e.g. SlideShare) and with parent companies (Microsoft).
- Advertising partners – Data such as profile info, usage data, inferred interests may be used for targeted advertising.
- Employers/recruiters – User profile data may be shared with prospective employers during the job seeking process.
While LinkedIn states they do not sell personal data, the extensive sharing with partners raises privacy concerns over user control.
Targeted Advertising
Like other social networks, LinkedIn relies on targeted advertising as a key revenue source. User data helps serve customized ads within the LinkedIn platform and across the web. Some concerns include:
- Lack of transparency – LinkedIn states it does not create individual profiles for ad targeting but serves ads based on information like profile fields, usage activity, device info, and inferred interests.
- No way to limit – There are no options within LinkedIn to limit ad targeting or data collection for advertising purposes.
- Behavioral tracking – LinkedIn tracks activity across devices and websites to serve targeted ads. Users have limited control to stop this tracking.
Profile Visibility
LinkedIn profiles are visible by default and only certain sections can be hidden. This makes it difficult to control what’s visible to the public versus private connections. Concerns include:
- Public visibility – Name, photo, headline, current positions are publicly viewable by default.
- Limited customization – Users can only customize the visibility of limited sections like education history and interests.
- Search engines – Public profiles are indexed by search engines like Google making info discoverable.
For privacy-conscious users, the inability to make profiles completely private is a limitation.
Data Retention
LinkedIn retains user data indefinitely after an account is closed. The only way to request deletion is to contact customer service. Key issues around data retention include:
- No automated deletion – No option to have data automatically deleted if account is closed.
- Unclear retention periods – LinkedIn states they retain data as needed to provide services but does not disclose exact retention periods.
- Limited deletion – Deleting an account does not ensure all data is deleted from LinkedIn’s systems.
LinkedIn’s indefinite retention of profiles and unclear deletion policies are concerning for those looking to minimize their data footprint.
Account Security
Maintaining strong account security is important given the sensitive professional data stored on LinkedIn. Some areas of concern include:
- Account hijacking – There have been incidents of hackers gaining access to LinkedIn accounts, often to send spam.
- Weak password policies – LinkedIn does not enforce password complexity or multi-factor authentication.
- Email security issues – LinkedIn has had breaches that exposed user email addresses.
While no social media platform is completely secure, LinkedIn’s security protections could be stronger to prevent unauthorized account access.
Conclusion
In summary, key privacy issues to consider with LinkedIn include:
- Extensive data collection and sharing with minimal user control
- Targeted advertising based on profile and usage data
- Public visibility of profiles with limited customization
- Unclear data retention policies and practices
- Account security vulnerabilities that have led to hijacking
Users should carefully weigh these risks against the benefits of using the platform. While LinkedIn provides valuable professional connections, it’s wise to be cautious about sharing personal information and utilizing privacy settings where available.
