Is Ancestry Safe for DNA Testing and Genealogy?
Ancestry is the largest genealogy platform offering DNA testing, family tree building, and historical record searches. While Ancestry has not experienced a breach comparable to 23andMe, the fundamental concerns about consumer DNA testing apply: genetic data is permanent, law enforcement can request access for criminal investigations, and the data has implications for biological relatives who never consented to testing. Ancestry is a more stable company than 23andMe, but genetic data collection by any commercial entity carries inherent long-term risks that warrant caution.
What Ancestry Collects
- DNA genotype data from saliva samples
- Genetic ethnicity estimates and DNA matches with other users
- Family tree data including names, dates, and relationships
- Historical document searches and genealogy research patterns
- Subscription and account information
Who Sees Your Data
- Ancestry LLC and its subsidiary platforms
- DNA matches who share genetic segments
- Law enforcement through a dedicated legal process request portal
- Research partners if you opt into the research program
- Family members who can see shared family tree data
Law Enforcement Access to DNA Data
Ancestry has received and responded to law enforcement requests for user DNA data. While the company states it requires valid legal process, the existence of a large DNA database creates a resource that law enforcement can potentially leverage. The use of consumer DNA databases in criminal investigations has solved numerous cold cases but also raises concerns about genetic surveillance. Your DNA does not just identify you but can be used to identify relatives, meaning testing affects your entire biological family even if they never consented to a database.
Genetic Data Permanence and Family Implications
Like all consumer DNA testing, Ancestry data is permanent and has implications beyond the person tested. DNA results can reveal unexpected parentage, unknown siblings, ethnic heritage that was not previously known, and predispositions to certain conditions. This information affects biological relatives who did not consent to testing. Family secrets can be revealed, and the emotional impact can be significant. Before testing, consider whether you and your family members are prepared for unexpected discoveries that cannot be undone.
Company Stability and Data Stewardship
Ancestry is owned by Blackstone Group, a major private equity firm, providing financial stability that 23andMe currently lacks. The company has been operating since 1983 in various forms and has a longer track record of data stewardship. However, private equity ownership means the company ultimate goal is return on investment, and DNA data is a valuable asset. If Ancestry is sold again, data could transfer to a new owner with different priorities. Regular review of privacy policies and maintaining the ability to delete your data are important regardless of current ownership stability.
Recommended Privacy Settings
| Setting | Where | Recommended |
|---|---|---|
| DNA Matching | Settings > DNA > DNA Matching | Review whether DNA matching is appropriate for your situation and disable if you prefer genetic privacy |
| Research Participation | Settings > DNA > Research | Opt out of research sharing programs to prevent genetic data from being used beyond genealogy |
| Family Tree Privacy | Family Tree > Settings > Privacy | Set family tree to private to control who can see your genealogical research |
Safer Alternatives
Research family history through public records and archives without submitting your DNA to any commercial database
HIPAA-protected genetic testing with professional counseling and stronger data protections than consumer services
Our Verdict
Ancestry is a more stable alternative to 23andMe but still carries the fundamental risks of consumer DNA testing: genetic data is permanent, law enforcement can request access, and testing affects biological relatives who never consented. The private equity ownership provides current financial stability but does not guarantee long-term data stewardship commitments. If you choose to use Ancestry, configure privacy settings carefully, opt out of research programs, and understand that your genetic data once submitted has implications that extend far beyond typical personal information. Caution is warranted for any consumer DNA testing service.

Frequently Asked Questions
Can the police use my Ancestry DNA?
Law enforcement has sought and obtained DNA data from consumer genealogy databases to solve criminal cases. Ancestry states it requires valid legal process for law enforcement requests and publishes transparency reports. However, even without directly accessing your account, investigative genetic genealogy techniques can use public DNA databases and family matching to identify individuals through their relatives DNA. By testing, you potentially provide information that can be used to identify family members in criminal investigations.
Is Ancestry more stable than 23andMe?
Yes. Ancestry is owned by Blackstone Group, a major private equity firm with substantial resources. The company has operated in various forms since 1983 and has not experienced the financial crisis that 23andMe is facing. However, private equity ownership means the company could be sold, and long-term data stewardship depends on future ownership decisions. Ancestry is more stable today, but genetic data commitments should be evaluated on a permanent timeline, not just current conditions.
Can I delete my DNA data from Ancestry?
Yes. Ancestry allows you to delete your DNA results and request destruction of your physical saliva sample. Go to Settings, then DNA, then Delete DNA Results. The process removes your genetic data from the Ancestry database and stops DNA matching. However, if your data was previously shared with research partners or if relatives have already seen your matches, that information cannot be fully recalled. Deletion prevents future access but does not erase all traces from systems or the memories of people who accessed your results.
