Terms of use

The short version

• Roo helps you understand your hair loss, follow a plan and track it. It's not a doctor and doesn't diagnose or treat anything. Talk to a doctor before you start, stop or change a medicine.
• The app is free. Roo Premium is a subscription you buy, renew and cancel through Apple. There's no free trial.
• Roo's AI can get things wrong. Check with your doctor.
• In the community, be kind, share only your own experience, and never sell anything or point to research chemicals. Breaking the rules gets posts removed and accounts banned.
• Roo may earn a commission from shop links. It never changes what Roo recommends.
• Your rights as a consumer under the law always stay yours.

1. Who provides Roo

Roo: Hair Loss Coach ("Roo") is the iPhone app, its widgets, Lock Screen routine and Apple Watch app, and this website at roohairloss.coach. It's provided by Ricardo Gruber, Schlossstr. 50, 9497 Triesenberg, Liechtenstein ("the provider"). Contact: contact@roohairloss.coach. More details are in the legal notice (Impressum).

These terms apply when you use the app or the website. You get the app from Apple's App Store, and Apple's Standard Licensed Application End User License Agreement is the licence for the app itself. These terms add the rules for Roo's own services, such as Roo Premium's features, the AI features, the community, the buddy and the website. Where the two cover the same point about the app's licence, Apple's licence applies. Apple isn't a party to these terms and isn't responsible for Roo's services. How Roo handles your data is in the privacy policy.

2. What Roo is and isn't

Roo is an education, planning and tracking tool. It asks about your hair, shows which pattern your hair loss looks most like, suggests a plan from fixed rules ranked by the evidence, reminds you, keeps your photos and lets you compare them over time.

Results differ from person to person, and many people see no change from a treatment. Roo makes no promise about what will happen to your hair. Treatment information in Roo is based on published studies and is being reviewed by medical professionals; the evidence grades say how strong the evidence is, not how well a treatment will work for you. Roo is not intended to be a medical device.

Roo shows information about research chemicals and medicines still in trials, because people ask about them. That information is a warning, not a recommendation. Roo never tells you where to get them, never links to sellers, and lets you track one only after a warning. Don't use them without a doctor.

3. Who can use Roo

You need to be 13 or older to use Roo. Most hair loss treatments are only for adults, and the plan never suggests medicines to anyone under 18. Where the law of your country sets an age below which a parent or guardian has to agree to online services (in many countries 16), you may use the AI features, the community and a buddy only with their consent until you reach it.

Roo has no sign-up. Your phone gets a random anonymous ID, kept in your iCloud Keychain, which links your community profile, buddy, invites and Lock Screen routine to you. Keep your phone and your Apple account secure, because anyone with them can use Roo as you.

4. Free and Premium

Free. The app is free to download. Your plan, routine, reminders, photos, before and after, the widgets, Learn, reading the community, the buddy and milestone shares are free.

Roo Premium is an auto-renewing subscription, sold by Apple through the App Store, yearly or monthly, at the price the App Store shows you before you buy. It adds what the app lists under Roo Premium, such as Ask Roo, the AI hair analysis, the timelapse, the quick video scan, posting in the community, shampoo scans and the doctor PDF, with the allowances the app shows (for example 10 questions to Ask Roo a day and 2 AI hair analyses in any 30 days). There's no free trial.

• Billing and renewal. Apple charges your Apple account when you buy, and again at the start of each period. Your subscription renews automatically unless you cancel at least 24 hours before the current period ends.
• Cancelling. Cancel at any time in your iPhone's Settings › your name › Subscriptions. You keep Roo Premium until the end of the period you've paid for.
• Refunds and withdrawal. Apple is the seller of the subscription, so refunds and any right of withdrawal are handled by Apple under its own terms, at reportaproblem.apple.com.
• Price changes. Apple tells you about a price increase in advance and, where the law or Apple's rules require it, asks you to agree before it applies.
• Restoring. Roo Premium belongs to your Apple subscription, so it works on your other iPhones and iPads with the same Apple account. Use Restore purchases in Settings if it doesn't show.

Your first AI hair analysis is free, once per iPhone, while it's offered. It's counted with Apple's DeviceCheck, so it stays used even if you delete and reinstall the app.

Invite a friend. When a friend subscribes with your code, they get their first month free, and you get a free month when their Roo Premium starts, up to 12 a year. Free months are Apple offer codes, redeemed on Apple's own page; a friend's free month is once per iPhone. Codes have no cash value and can't be sold or swapped. Roo may end the invite programme for new invites; months already earned stay yours. Using fake accounts, devices or subscriptions to collect free months isn't allowed.

Your rights for digital products. If a paid feature doesn't work as described, your statutory warranty rights for digital services apply (in Liechtenstein under the Konsumentengewährleistungsgesetz, KonsGG, and otherwise under the mandatory consumer law of the country where you live). In rare cases the AI features may be paused for a short time, for example when the monthly capacity Roo has with its AI provider is reached; the app then says when they'll be back. This doesn't limit your statutory rights.

5. AI features

Ask Roo and the AI hair analysis use Claude, an AI model made by Anthropic. Before your first use of each, the app shows you what's sent and asks for your consent; you can withdraw it in Settings. AI answers are made by a machine from what you share. They can be wrong, out of date or incomplete, and they're no substitute for a doctor. The AI hair analysis points out visible signs, such as thinning areas, patches, redness or flaking, that may be worth showing a dermatologist. It doesn't diagnose anything. Don't send photos of anyone else, or photos showing more than your hair and scalp need to. You may use what the AI writes for yourself; don't present it as medical advice to others.

6. Community

The community is a place for members to share their own experience. Posts come from members, not doctors. Roo doesn't check them for medical accuracy and isn't responsible for what members write.

Joining. To post you need a community profile and to accept the community rules. Starting threads and replying need Roo Premium; milestone shares and reviews don't.

The rules.

• Share your own experience. Nobody here is your doctor.
• Be kind. No insults, harassment or threats, and never mock anyone's hair or looks.
• No selling, ads, referral codes or spam, and no sources, prices or links for research chemicals or prescription medicines without a prescription.
• Keep personal details, such as phone numbers, addresses or another person's photo or health, private.
• No hateful, sexual, violent or abusive content, nothing illegal, and no content that encourages self-harm. There's no tolerance for these: they're removed and their authors are banned.
• Don't pretend to be someone else, including a doctor or Roo.
• Post only what you have the rights to.

Moderation. Every post, reply, review, name and picture is checked before it appears, first by automatic checks and then by Anthropic's Claude model. Content that breaks the rules or the law isn't published, or is removed. You can report any post or review from its menu, or by email to contact@roohairloss.coach with the post and why. A post you report is hidden for you at once; a post reported by three members who can post is removed for everyone, and Roo reviews reports and removals. An author whose posts are removed three times can no longer post. Roo may also remove content, limit posting or end access to the community when the rules or the law are broken, taking into account how serious and how frequent the breach is. If your content is removed or your access limited, you can ask Roo for the reasons and to look at it again by email. You can block any member, which hides their posts and reviews from you.

Your content. What you post stays yours. By posting it, you allow Roo to store, show, copy and adapt (for example resize or crop) it in the app for members, for as long as it's posted, worldwide and without payment, only to run the community. This permission ends when you delete the post, your profile or all your data; members may already have seen or saved it. Posting anonymously hides your name from members, not from Roo's moderation.

Buddies. A buddy sees only the name you gave them, your streak and whether today's routine is done, and you can nudge each other with a fixed message. Either of you can end it at any time.

7. Shops, online doctors and clinics

Roo links to products from shops and partners. Roo isn't the seller: when you buy, your contract is with the shop, under its terms, prices and delivery. Prices in Roo are rough guides and may differ. Some links are affiliate links, so Roo may earn a commission when you buy, at no extra cost to you. Commission never changes Roo's plan, its ranking of treatments or which product is Roo's pick, which are chosen for trust and evidence.

Prescription-strength products need a doctor first. Online doctors linked in Roo are independent providers who decide for themselves whether to prescribe anything. Partner dermatologists and clinics pay to be listed and are marked "Partner"; best-rated lists come from Google Maps and aren't checked by Roo. Check a provider's qualifications before you book. Roo isn't responsible for third-party products, services or websites.

8. Fair use and intellectual property

Use Roo only for yourself and in line with the law. Don't:

• get around Roo Premium, its allowances, rate limits or DeviceCheck, or share access to them;
• use bots, scripts or other automated access, or copy, scrape or resell Roo's content;
• attack, overload or probe Roo's systems, or interfere with other members' use;
• reverse engineer the app, except where the law allows it.

Roo's name, the character Roo, the illustrations, texts, plan rules and software belong to the provider or its licensors and are protected by copyright and other rights. Parts of the app use open-source software and data under their own licences (for example Open Beauty Facts data under the Open Database License), which apply to those parts.

9. Liability

The provider is liable without limitation for injury to a person (life, body or health), for damage caused intentionally or through gross negligence by the provider or anyone the provider is responsible for, under Liechtenstein's law on product liability (Gesetz über die Produktehaftpflicht), and where a guarantee has been given. For consumers, these cases can't be excluded or limited anyway (Art. 8 of the Konsumentenschutzgesetz, KSchG).

For slight negligence, and as far as the law allows, the provider is liable only for breaching an essential contractual obligation, meaning one that makes the proper use of Roo possible in the first place and on which you may regularly rely. In that case liability is limited to the damage that was foreseeable and typical for this kind of contract when it was made.

These limits also apply to the provider's representatives and helpers. Mandatory statutory liability, and your statutory warranty rights for digital services, stay unaffected.

10. Ending, changes and availability

You can stop using Roo at any time. Delete the app, and use Settings › Delete all my data in the app first to delete what Roo's server keeps about you. Cancel Roo Premium with Apple; deleting the app doesn't cancel it.

Roo may suspend or end your use of its server features (such as the community, the buddy or invites) for a serious breach of these terms or the law, or for good cause; the features that run on your phone keep working. Roo may stop offering the free service with reasonable notice.

Changes to Roo. Roo keeps improving and may change, add or remove features. For a paid feature, Roo makes a change only for a valid reason (for example new evidence, safety, the law, security, or a change at a provider Roo depends on), at no extra cost to you, and tells you clearly in advance. If a change harms your use of Roo Premium more than slightly, you may end the contract free of charge within 30 days, as the law provides (in Liechtenstein Art. 27 KonsGG; the mandatory consumer law of the country where you live may give you the same right).

Changes to these terms. If these terms change, the date at the top changes and the app or website tells you in advance. Changes that affect an existing subscription apply only if you agree to them; if you don't, the earlier terms keep applying until your subscription ends.

Roo aims to keep its services available, but they may be interrupted by maintenance, faults or causes outside Roo's control.

11. Law and disputes

These terms are governed by the law of the Principality of Liechtenstein, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. If you're a consumer, this choice doesn't take away the protection of the mandatory consumer law of the country where you usually live.

If you're a business, the courts of the Principality of Liechtenstein have jurisdiction. For consumers, the courts that have jurisdiction under the mandatory law apply, including those where you live.

The EU's online dispute resolution platform closed on 20 July 2025. In Liechtenstein, consumer disputes can be taken out of court to the Amt für Volkswirtschaft (Office of Economic Affairs), the body for consumer disputes under the Alternative-Streitbeilegung-Gesetz (AStG), www.llv.li. [Choose one: "The provider is willing to take part in its dispute resolution proceedings." or "The provider is neither obliged nor willing to take part in dispute resolution proceedings before a consumer dispute resolution body."] Before anything else, write to contact@roohairloss.coach; most things are sorted out quickly.

If any part of these terms is invalid, the rest still applies, and the statutory rules take the place of the invalid part.

The consumer rights mentioned above are in Liechtenstein's General Civil Code (Allgemeines bürgerliches Gesetzbuch, ABGB), Konsumentenschutzgesetz (KSchG) and Konsumentengewährleistungsgesetz (KonsGG), and in the mandatory consumer law of the country where you live.
