Your sleep data stays with you; Remi uses it to personalize, never to sell. BUILT FOR CALM, NOT ENGAGEMENT No streaks. No sleep scores to chase. No urgency. Remi is designed for the nervous system, not the dopamine loop. PRIVACY, CLEARLY • No third-party analytics in the app • Your conversations are processed by Anthropic's Claude (no training on your data, auto-deletion within 30 days) • Voice mode uses ElevenLabs — your audio isn't retained after the session • Delete your account and all data any time from Settings • Full policy at rhythmicly.com/privacy Remi is for anyone who's had enough of sleep tech yelling at them.
