Yes. SelfDecode has a robust privacy policy that ensures you own your genetic code first and foremost. They keep it stored on a third-party server separately from your account and personal information and use exceptionally strong encryption. They also have an entire team of employees dedicated to protecting your information. There are a few cases where they may use your information for marketing or research purposes, but almost always in aggregate unless you explicitly consent otherwise.
For maximum security, we suggest doing your DNA testing with SelfDecode; uploading previous companies’ raw DNA files almost always means you revoke the first company’s liability if anything goes wrong.
