Read the full notice
- edit_noteWhat you logPeriods, symptoms, pain, mood, sleep, meals and food photos, weight, calm minutes, and your getting-to-know-you answers, which can include pregnancy, hormones, medicines and health history.
- smartphoneKept on this phone unless you choose backupYour diary stays in this browser, so clearing the browser or losing the phone can lose it. You can export a copy any time from You. Cloud backup is a separate choice below: a copy kept in your account in a secure database hosted in Singapore, which other Rhythme users cannot see; authorised Rhythme administrators and the companies that run the database can reach it only to run, secure or support the service.
- auto_awesomeLuna’s AI help is your choiceReading a note, naming the food in a photo and writing a journal reading are three separate choices. Each stays off until you turn it on. Your name is never added, and Rhythme keeps none of it.
- lockWhat we will not doWe do not sell your data or use it for ads, and Rhythme does not keep what Luna reads for you.
- dnsOrdinary service recordsOur web host keeps standard connection logs and fonts load from Google. Using a Rhythme Plus code records that use with a scrambled network address, to stop misuse. There is no advertising, and no analytics unless you turn on “Help improve logging” below; then only group counts and averages across at least 20 adults are produced.
- tuneYou stay in controlEvery choice below can be turned off any time from You, as easily as it was turned on, and each change is kept on record with the notice version you read. Export your diary, or delete everything on this phone, any time from You.
- medical_informationA friend, not a doctorPredictions and Luna can be wrong. Rhythme does not diagnose, treat, or work as contraception. In an emergency, call your local emergency number.
- cakeFor adultsRhythme is for people 18 and over. For that we keep only your confirmation. Your birthday is optional: a month and a day, with the year only if you add it, kept on this phone and used only for the birthday card.
info
Your earlier answers said you were under 18Rhythme is now for adults only. Tick the confirmation below only if it is true today; otherwise choose “I am under 18”.
Optional extras, all off until you turn them on
