Do I get any money back if I don't die by the end of the life insurance policy term?

No.

You don’t receive any money back if you outlive the policy term. At the end of your term, you simply stop making payments and your coverage ends.

However, if you purchase a return of premium term life insurance policy you will get back almost all of the premiums you paid, if you outlive the duration of your policy term.

Keep in mind, premiums are higher for a return of premium policy, compared to a regular term life insurance plan.

So, you are betting that you will outlive your term life policy if you purchase return of premium coverage.
