Terms of Service

These terms are between you and Vessa, and they apply when you download, open or use the Vessa app or this website. Using the app means you accept them. If you do not, the app is not for you — delete it, and email support@vessa.care if you would like your account removed.

Vessa analyses photographs of your skin, produces scores, and generates skincare routines from products you own using AI models. It is a consumer skincare app.

It is not a medical device and does not provide medical advice or a diagnosis. Scores are estimates from a photograph, not clinical measurements. Nothing in the app substitutes for a dermatologist or doctor — see one for anything painful, spreading, bleeding, or changing quickly, and for any mole or lesion you are unsure about.

Routines avoid combinations known to irritate and respect the pregnancy, sensitivity and prescription answers you give, but you are responsible for what you put on your skin. Patch-test new products, read their labels, and stop using anything that causes a reaction.

• You need an account, created with an email address or Sign in with Apple, and you must be at least 13 — or older, where your country sets a higher age for consenting to online services.
• Keep your sign-in details to yourself; you are responsible for what happens under your account.
• One person per account. Scores and routines are built from one person's skin and mean nothing if two people share a login.
• You can delete your account in the app at any time. It takes effect immediately and removes your data as described in the privacy policy.

Some features require a paid subscription. Subscriptions are sold and charged by Apple through your App Store account, not by Vessa — we never see your payment details.

• The price, billing period and what is included are shown in the app before you buy.
• Subscriptions renew automatically unless you cancel at least 24 hours before the period ends.
• Cancel or change a subscription in iOS Settings → your name → Subscriptions. Deleting the app does not cancel it.
• Refunds are handled by Apple under its own policy. Vessa cannot issue them, but email us if something has gone wrong and we will help where we can.

Your photos and what you write stay yours. To run the service you give Vessa permission to store them and to send them to the AI providers listed in the privacy policy so they can be analysed and answered. That permission exists only to operate the app for you: your photos are not published, shown to other users, sold, or used to train general-purpose AI models.

Upload only photos you are entitled to upload — your own face, and products you have.

• Do not use Vessa to harass anyone, upload other people's photos without their permission, or upload anything illegal.
• Do not attempt to break, overload, scrape or reverse-engineer the service, or to work around usage limits.
• Do not resell access, or present Vessa's output as a medical opinion or as your own professional advice.
• Accounts that do these things can be suspended or removed.

Vessa's scores, routines and chat answers are generated by AI models. They can be wrong, inconsistent between scans, or confidently mistaken, and lighting, camera angle and makeup all move the numbers. Treat them as a structured second opinion to reason with, not as fact. Vessa gives no guarantee of any particular result for your skin.

The app is provided as it is, and may change: features can be added, altered or withdrawn, and service can be interrupted for maintenance or by a provider's outage. If a change is significant and affects a paid feature, you will be told inside the app. Vessa may also update these terms; the date at the top changes when it does.

To the extent the law allows, Vessa is not liable for indirect or consequential loss, for lost data, or for the results of following advice generated in the app. Where liability cannot be excluded, it is limited to the amount you paid for the app in the twelve months before the claim.

Nothing here removes rights you have that cannot be removed — including consumer protections, and liability for death or personal injury caused by negligence.

If you are a consumer, you keep the protection of the mandatory laws of the country you live in, and you can bring proceedings in your local courts. Please email support@vessa.care first — most problems are quicker to fix than to argue about.
