Privacy first.
Your Dreams, Only You Can See.
We use industry-leading encryption technology. All sleep data is stored locally on your device only, never in the cloud. We cannot view it, and we will never sell it.
Stored on your device
Your most personal data never leaves your device. Sleep, heart rate, and other health metrics are stored locally — not on our servers.
Only with your consent, anonymized & encrypted
Nothing reaches the cloud unless you allow it. And when it does, it’s anonymized and de-identified first, then protected with industry-leading encryption in transit.
We can’t see your data, and we’ll never sell it.
Questions?
Everything you might wonder before your first night with Mellows. Can’t find your answer? We’re just a message away.
Mellows is an AI-powered sleep companion for iPhone. It combines designer-crafted spatial audio soundscapes, personal sleep intelligence — your Sleep Score, Recovery, Sleep Age and more — and a sleep assistant named Mia, all built on the sleep data in Apple Health.
We’re in early access now — join the waitlist to be first in.
With your permission, Mellows reads your sleep data from Apple Health. For that you’ll want an Apple Watch — or another wearable that records your sleep to Apple Health.
It turns your nightly data into your Sleep Score, Recovery, Sleep Age, and trends — and gives Mia the context to answer questions about your sleep.
Mellows is free to use — you can see your Sleep Score, Recovery, Sleep Age and daily insights at no cost. Premium unlocks Trends, chatting with Mia, and the full soundscape library, with a 7-day free trial on the annual plan.
Your raw health measurements stay on your device; only derived sleep summaries sync securely to power your trends and Mia. We never sell your data. (See Privacy First above.)
