• Access Controls: Limiting access to data to authorized personnel.
• Data Anonymization: Removing personally identifiable information from data used for research purposes.
• Transparency: Providing users with clear information about how their data is used.

However, no security system is foolproof, and the risk of data breaches remains a constant threat. Users should carefully review 23andMe's data privacy policy and consider the potential risks before submitting their DNA.

Data Deletion: Taking Control of Your Genetic Information

Recognizing the importance of user control over their data, 23andMe provides options for users to delete their genetic information from the company's databases. This is a crucial feature that empowers individuals to take ownership of their personal data and mitigate potential privacy risks.

The data deletion process typically involves several steps:

• Account Closure: Users must first close their 23andMe account.
• Data Deletion Request: Users must then submit a formal request to delete their genetic data.
• Verification: 23andMe will verify the user's identity to ensure that the request is legitimate.
• Data Deletion: Once verified, 23andMe will permanently delete the user's genetic data from its databases.

It's important to note that data deletion is irreversible. Once the data is deleted, it cannot be recovered. Users should carefully consider the implications before proceeding with data deletion.

Even after data deletion, some anonymized or aggregated data may still be retained for research purposes. However, this data will not be linked to any individual user. 23andMe's commitment to data deletion reflects a growing awareness of the importance of data privacy and user control in the digital age.
