Privacy Policy
Juno is an independent skincare guide. It is not affiliated with any skincare brand, retailer or medical provider. The short version: what you tell Juno stays on your iPhone. The only exception is the text Juno needs to read to answer you, and that is used only for the answer and is not kept.
What stays on your iPhone
- What Juno remembers about your skin, and your chats.
- Your shelf: the products you use, when you started and stopped them, and why.
- Your daily check-ins, the spots you mark on the face map, and your progress photos.
- If you turn on cycle-aware tips, the days your period started.
- Your settings.
This is stored only in the app and protected by your iPhone's passcode. Delete all of it anytime in You → Privacy → Delete everything I've told Juno, or by deleting the app.
What is sent so Juno can answer
Juno uses AI to understand what you write. When you send a message, or your story during setup, the app sends three things to Juno's server:
- Your message.
- The last few messages of that chat.
- A short summary of your skin: what Juno remembers, the products on your shelf, your recent check-ins and spots, and a period heads-up if you turned that tip on.
Juno's server passes this to an AI model and returns the answer. The model is OpenAI's open gpt-oss model, run by Cloudflare Workers AI.
This information is used only to write your answer. It is never used for advertising and never sold. Juno's server does not store your messages or your skin summary. The app asks your permission before Juno reads anything. If we ever add another AI provider, we will name it on this page first.
Some of this is health information, such as acne, skin reactions, pregnancy or your cycle. Please only share what you're comfortable sharing.
Membership and message counts
To check your membership and count your 40 messages a day, the app sends Apple's signed record of your subscription to Juno's server. That record contains a transaction number, not your name, email or Apple ID. Linked to that transaction number, the server stores two things: a message count for each day, which is deleted automatically after a few days, and any extra messages you bought.
During setup, before you have a membership, the server counts a few free reads using a random number the app creates. To prevent abuse, it also keeps a daily counter for each network address, which is deleted automatically.
Barcode lookups
When you scan a barcode, only the barcode number is sent to Open Beauty Facts to fetch the product's name and ingredients. If the product isn't there, the number is also checked in its sister databases. No information about you is included.
Camera and photos
The camera reads barcodes and ingredient labels, and takes progress photos if you choose to. Labels are read on your iPhone using Apple's on-device text recognition. Progress photos are saved only inside the app on your iPhone and are never uploaded.
UV tip
If you turn on the daily UV tip, the app uses your approximate location to get today's UV index from Apple Weather. Juno doesn't store your location or send it anywhere else.
Reminders
iOS schedules routine reminders, check-ins and the weekly report on your iPhone. You can turn them off in the app or in Settings.
Shopping links
Some answers include "Buy" links to products on Amazon. As an Amazon Associate, Juno earns from qualifying purchases. This never changes what Juno recommends. If you tap a link, Amazon handles your visit under its own privacy notice. Juno receives only Amazon's totals of qualifying purchases, never who bought what.
Purchases
Memberships and message packs are bought through Apple's App Store. Apple handles the payment. We never see your payment details, name, email or Apple ID.
No tracking, no ads
Juno has no advertising, no analytics and no tracking. There is no account or sign-in.
Not medical advice
Juno explains skincare and research. It isn't a doctor and can't diagnose. See a dermatologist for anything that worries you.
Children
Juno is not directed to children under 13.
Changes
If this policy changes, we will update this page and the date above.
