Is It Safe To Upload DNA Online? Real Risks Explained

Uploading your raw DNA can unlock new features on third party sites. It can also expose sensitive information. Here is how to think about the tradeoffs and safer options.

Real world risks

• Data retention - copies can persist long after you delete your account
• Scope creep - features expand and new parties get access over time
• Reidentification - anonymized data can sometimes be linked back to people
• Breaches - even careful platforms are targets

A simple evaluation checklist

• Who operates the service and where is it based
• Does the policy clearly state retention periods you can understand
• Are there options to opt out of research or sharing
• Can you delete your data and request erasure confirmation
• What authentication is available - two factor is preferred
• Do they publish a security page with contact details for issues

Safer alternatives

• Keep computation local with a browser based tool that never uploads your data
• If you do upload, create a unique email and strong password
• Read the privacy policy and retention terms before using a site
• Remove old uploads you no longer need

You can learn a lot without sending data anywhere. Read how our approach works in on device DNA analysis and see the walkthrough in browser based DNA analysis. For a deeper policy view, read genetic traits and privacy.

In short, treat DNA like any sensitive document. Share only with services you trust, and prefer local processing when you can.
