Privacy policy

Last updated 19 October 2026

shelfie helps you understand your skin and hair, check products against them, and keep a routine. To do that it stores some information about you. This page says what, why, where it goes, and how to remove it.

What we collect

• Your account. The email address you sign up with, or the identity your sign-in provider (Apple or Google) shares with us, plus a username, an avatar colour and an age range if you set them.
• Your quiz answers. The skin and hair questions you answer and the type the app works out from them.
• Health information. Two quiz questions ask about health: whether you are pregnant or breastfeeding, and whether you have been diagnosed with a skin condition such as eczema, rosacea or melasma. Both are optional. We use these answers only to adapt your routine and to flag ingredients you should be careful with. They are never used for advertising, never sold, and never shared with other members. You can answer "None", and you can change or clear your answers at any time in Account.
• What you keep in the app. The products on your shelf and in your cart, your ratings and reviews, when you use each product, your routine log, your daily skin log (grades, tags and notes), and the friends you add.
• Skin photos. Photos you choose to add to a skin-log day. They are stored in a private folder that only your account can open, through short-lived links. They are never shown to other people and are never analysed without you asking. The app strips the camera's location and device data from each photo before saving it.
• What you post and share. Posts, questions, comments, likes, the products you add to your shelf, finish or review, and the products you share on the feed. Friends and other signed-in members can see these, including the products you mark “Not for me” and the reason you give; you can limit them to friends in Account (“Who sees my activity”). Your skin log and photos are never shown to anyone.
• Notifications. A device token so we can send the reminders and alerts you turn on. You can turn them off in the app or in iOS Settings.
• Beta sign-ups. If you ask to join the beta on shelfie.care, the first name, email address, optional Instagram or TikTok handle and answers you give us. We use them only to choose who to invite and to email you about the beta, and we delete them when you ask.
• Usage and errors. A short list of named events (for example "product added", "skin logged") and error reports, identified by your account id only. No names, photos, notes or product names are included, with one exception: when a search finds nothing, the words you typed are kept so we can add what is missing. Session recordings, when enabled, mask every image and every typed field.

Why

To run the app: build your routine, score products against your skin, show your friends' shelves, remind you in the evening, and find and fix what breaks. We do not sell your information and we do not show advertising.

Who handles it

• Supabase stores your account, your data and your photos.
• PostHog receives the usage events and error reports described above.
• Apple and Google handle sign-in when you choose them, and Apple delivers notifications.
• Vercel hosts the web version of the app.

Each of these processes data only to provide its service to us.

What other people can see

Signed-in members can see your username, your skin and hair type, your shelf, and what you post. Your quiz answers, logs, photos, cart and email are yours alone.

Keeping it and deleting it

We keep your data while your account exists. You can delete a skin-log day, a post or a product at any time, and you can delete your whole account from Account → Settings → Delete account. That removes your profile, answers, shelf, logs, photos, posts and comments straight away and cannot be undone. You can also write to us and we will do it for you.

Your health information and your rights

Answering the two health questions is your consent to the use described above, and you can withdraw it by clearing those answers in Account or by deleting your account. If you live in a state with a consumer health data law, such as Washington or Nevada, you also have the right to know what health information we hold about you, to have it deleted, and to a list of anyone we have shared it with, which is no one. Write to the address below and we will act within thirty days.

Children

shelfie is not intended for children under 13, and we do not knowingly collect their information.

Not medical advice

Everything the app says about your skin, your hair and your products is general information built from your own answers. It is not a diagnosis or a treatment plan. See a doctor or a dermatologist for medical concerns.

Changes

If this policy changes in a way that matters, the app will say so the next time you open it.
