— Frequently Asked
What happens with my data?
Your data is encrypted, never sold to any external party, and never used for advertising. It’s yours, you can always request full deletion. Period.
What if my sleep is interrupted?
That’s exactly what Meri was made for. Meri measures throughout the entire night and knows how to filter out disturbances, getting up for a baby, the bathroom, or anything else that can disrupt sleep. The system finds your true resting point, and what you get in the morning is a reliable reading.
Is it safe to wear overnight
A: Absolutely. Meri is completely radiation-free while you sleep. It never connects to your phone at night, securely syncing your data just once in the morning.
Are the patches reusable
For optimal hygiene and comfort, the medical-grade patches are designed to be replaced regularly, while the core device is yours to keep. We seamlessly send you a new batch of patches every month with your subscription.
Is there a learning curve before I can trust the data?
Not at all. You can rely on MERI from the very first day. The autonomous algorithm simply starts with a broader fertile window to prioritize your safety. As it continuously tracks your data, the window customizes and narrows to your exact rhythm.
