What a pointless app. You have a brain. it processes memories. Brains have worked pretty well for millions of years recording memories. And they don't require a Terms of Service or Privacy Policy.
You mean that notoriously unreliable system which drifts over time by re-storing altered information during every recall, selectively stores some details and not others, and nearly always functions poorly during old age, the time when people would most like to tell stories and reminisce? That one?
