You can choose whether your sample is stored

The privacy summary says you may choose sample storage; if you do not, the sample is destroyed after the laboratory completes its work.

This choice concerns sample storage after laboratory work; the summary says a discard choice cannot be reversed.

Research participation is optional, and you can opt out

If you choose to participate in research, the privacy summary says your deidentified data is pooled with other participants and you can opt out later.

This applies only if you choose to participate in research.

Posts get a broad, lasting license, though you keep your rights

For content you submit or post, the terms grant 23andMe a perpetual, irrevocable license to use and share it; they exclude genetic and health information from this content definition.

This applies to User Content submitted, posted, or displayed through the service, which the terms define to exclude genetic or health information.

Research products based on your information bring no promised payment

If research or commercial products include or result from your information, the terms say you receive no rights in those products and no compensation.

Research participation is described as voluntary and based on an Institutional Review Board-approved consent document.

Deleting your account opts you out of research and discards your sample

The privacy summary says account deletion opts you out of research and discards your sample, and that deletion cannot be cancelled or reversed.

The described effects concern research participation and your sample; the excerpt does not explain the handling of other information.

The terms allow access to be ended or restricted broadly

The terms allow termination without prior notice and say 23andMe may restrict website access for any reason.

The terms require individual arbitration, with a 30-day opt-out

The terms generally require binding arbitration and waive class or collective actions; they provide a 30-day window to opt out of those provisions.

The terms provide exceptions to arbitration and a 30-day opt-out; if you do not opt out within the stated window, the terms say you will be bound by the arbitration provisions.

The terms require a 60-day dispute process before filing

Before arbitration or litigation, the terms require at least 60 days of informal negotiation and an individual conference that you must attend.

This process applies before initiating arbitration or litigation under the terms.

Payments are generally nonrefundable, with a failed-sample exception

The terms say payments are generally nonrefundable, but promise a refund less shipping and handling if a sample fails a second processing attempt.

The failed-sample refund applies only after the same sample fails a second processing attempt; the separately referenced Return and Refund Policy was not supplied.

A failed sample gets another processing attempt at no charge

If the first sample-processing attempt fails, the terms promise a free reprocessing attempt and, if that fails, a free collection kit for a second sample.

This applies when processing fails for one of the reasons described in the terms; after the second attempt fails, the terms provide a refund less shipping and handling instead of another kit.
