Mewa terms

Last updated 14 november 2026.

Using mewa

mewa is a free period tracker for your own personal use, made by cubeshell llc. by using it you agree to these terms. if you don’t agree, please don’t use it.

Not medical advice

mewa is a tracker, not a medical device. it doesn’t diagnose anything and it isn’t birth control. an ovulation estimate is always an estimate, never a promise. talk to a doctor or nurse about your health.

Age

you need to be 13 or older to use mewa, or 16 or older in the european economic area and the uk.

Your content

what you log and the cards you make are yours. you choose what to share and with whom, and you’re responsible for what you send. please don’t use mewa to hurt, harass or embarrass anyone.

Your person

connecting a person comes in a later version. when it does: only add someone who knows you and would want to hear from you, using their real number. they decide whether to say yes, and they can leave any time. please don’t use mewa to pressure, track or embarrass anyone.

Texts from mewa

mewa heads-ups: when someone adds you on mewa and you text “yes, i’m in” to mewa’s number, mewa sends you short text messages only when that person chooses: a heads-up about how they are doing, and at most three one-tap hints a month. message frequency varies, at most 8 messages a month. message and data rates may apply.

reply STOP to stop all messages, START to get them again, and HELP for help, or write to contact@cubeshell.com. wireless carriers are not liable for delayed or undelivered messages. texts are sent in the us and canada. how mewa handles your number is in the privacy policy.

mewa’s messages can be delayed or not delivered, and they wait during quiet hours. don’t rely on mewa for anything urgent or in an emergency.

Mewa plus

purchases are not available yet. when they are, they will go through your app store, and its terms and refund rules will apply.

No guarantees

we work hard to keep mewa accurate and working, but it’s provided as it is, without warranties. as far as the law allows, mewa isn’t liable for decisions you make based on the app or for data lost from your phone. nothing here takes away rights you have by law.

Changes
