Questions and answers
What is Plume?
Plume is a health journal for iPhone. You say, type or photograph what you ate and how you slept and felt, and Plume keeps it as a journal of your days. After about a week of entries it starts telling you patterns from your own days, and it can set up small experiments to test them.
Who is Plume for?
People who want to keep track of food, sleep, mood and energy without filling in forms or counting calories, and who would like something to look back over their days for them. Plume is for adults, 18 and older.
How much does Plume cost?
Plume is free during the beta. If paid features are added later, you will be told before anything is charged, and you choose whether to pay.
Which devices does Plume run on?
iPhone with iOS 17 or later. There is no Android or web version.
Do I need an account?
No. You can use Plume without signing in. Signing in, with Sign in with Apple or a code sent to your email, lets you reach the same journal from another device.
Does Plume count calories?
Not in the way a calorie counter does. You never look up a food or enter a number, and there are no daily targets. Plume makes rough estimates from what you wrote, keeps them in the background, and labels them as estimates.
How long before Plume tells me something?
About a week of entries. Before that there are too few days to compare, and Plume says so instead of guessing. Every pattern it shows says how many days it rests on and how sure Plume is.
Is Plume a medical device?
No. Plume is a wellness journal, not a medical device, and nothing in it is medical advice. It does not name conditions or suggest changes to medication. For those questions it points you to a doctor or pharmacist. In an emergency, call your local emergency number.
What languages does Plume understand?
English and Chinese, including both mixed in one sentence. Your own words are kept exactly as you wrote them.
Does Plume work with Apple Health?
Yes, if you allow it. Plume reads summaries such as sleep, steps and workouts from Apple Health so they sit next to what you wrote. It never writes to Apple Health. The Privacy Policy lists exactly what is read.
Where does my data go?
Nothing leaves your iPhone until you agree to it in the app. After that, your entries, photos and audio are read by OpenAI’s models so Plume can understand them, and they are not used to train models. OpenAI may keep them for up to 30 days to prevent abuse. Plume is hosted on Cloudflare, and sign-in emails are sent through Resend. There are no ads, your data is not sold, and the app contains no third-party analytics SDK. The Privacy Policy and the Consumer Health Data Privacy Policy have the details.
How do I export my data?
In the app, open Settings, then Privacy & data, then Export. You get everything as JSON or CSV.
How do I delete my account and data?
In the app, open Settings and choose Delete account & data. You can also ask by email. The steps are on the delete your account page.
Plume understood something wrong. What do I do?
Open the entry and correct it. You can change what Plume read from an entry, edit the entry itself, or delete it. Estimates are only estimates, and your correction replaces them.
How do I reach a person?
Email help@plumeapp.net. It helps to say which iPhone and iOS version you use and what you were doing when the problem happened. Please do not send health details you would rather not put in an email.
Plume cannot answer medical questions. If you are worried about your health, talk to a doctor. In an emergency, call your local emergency number.
