Last updated: August 12, 2026 · Applies to the Tansy iOS app and this website.
By using the Tansy app or this website, you agree to these terms. If you do not agree, please do not use them.
Tansy grades products and meals against the skin profile you describe, and a check-in records observations about your own skin over time. Grades and observations are informational. They are not a diagnosis, treatment, or medical advice, and they are not a substitute for a dermatologist or other clinician. If you have a medical concern about your skin, see a professional.
Grades come from a published rubric applied to ingredient lists and nutritional estimates. They are our best honest read of the available data against your profile, and the data can be incomplete or wrong. A grade is a starting point for your own judgment, not a guarantee that a product or food will or will not affect your skin.
If you join the waitlist on this site, we use your email to tell you when Tansy launches. Details are in the Privacy Policy. You can leave the list any time by emailing us.
Tansy offers an auto-renewing subscription, Tansy Pro, in two lengths:
Prices are in US dollars and may differ in your local currency and by region. The price you will be charged is always shown in the app before you confirm.
Payment is charged to your Apple Account when you confirm the purchase. Your subscription renews automatically unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the period ends, at the price of the plan you selected.
You can manage or cancel at any time in Settings on your device: tap your name, then Subscriptions. Cancelling stops the next renewal; it does not refund the period you are currently in, and you keep access until that period ends. Deleting the app does not cancel a subscription.
Free trials. If you start the 7-day trial and do not cancel before it ends, it converts to a paid annual subscription automatically and your Apple Account is charged. Cancel at least 24 hours before the trial ends to avoid being charged. Any unused portion of a free trial is forfeited if you buy a subscription before the trial ends.
Refunds are handled by Apple, not by us. Request one at reportaproblem.apple.com.
Product recommendations may include retailer links that pay us a commission at no cost to you. Grades and recommendations are computed from the ingredient rubric alone and are never influenced by commissions.
Your photos, logs, and profile stay yours. Face photos never leave your device. We claim no rights over anything you create in the app.
The app, this site, and their content are ours or our licensors'. Product data comes from Open Beauty Facts under the Open Database License. Don't copy, resell, or reverse-engineer the app.
Don't misuse the app or site: no breaking, probing, or overloading them, and no using them to break the law.
Tansy is provided as-is. To the maximum extent the law allows, we are not liable for indirect or consequential damages arising from your use of the app or site, and our total liability is limited to what you paid us in the twelve months before the claim.
We may update these terms. If a change matters, we will say so in the app or on this site before it takes effect. Using Tansy after a change means you accept the updated terms.
