Terms of Service

Radical Fat Loss (iPhone & Apple Watch) and this website
Effective date: 30 August 2026 · Version 1.4
Provider: Radical Health OÜ, Estonia

1Agreement to these terms

These Terms of Service ("Terms") govern your use of the Radical Fat Loss application for iPhone and Apple Watch (the "App") and the radicalhealth.app website (the "Site"), together the "Service," provided by Radical Health OÜ (Estonian registry code 17536495), Estonia ("we", "us", "Radical Health").

By downloading, accessing, or using the Service, you agree to these Terms and to our Privacy Policy. If you don't agree, please don't use the Service. If you are using the Service on behalf of someone else, you confirm you're authorised to accept these Terms for them.

3Eligibility

The Service is intended for adults aged 18 or older. Do not use the Service if you are under 18. The App concerns weight, eating, and fasting; it is not intended for anyone for whom tracking those would be inappropriate, including anyone with a history of disordered eating. By using the Service you confirm you meet these requirements. If the date of birth on your profile is under 18, the App switches off personalized weight-loss targets, fasting guidance, AI coaching, cloud AI, and analytics.

4Licence to use the App

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable licence to download and use one copy of the App for your own non-commercial use on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. The App is licensed, not sold, to you.

You agree not to, and not to permit anyone else to: copy, modify, or create derivative works of the App; reverse-engineer, decompile, or disassemble it except to the limited extent the law expressly permits; rent, lease, lend, sell, sublicense, or distribute it; or remove any proprietary notices.

6Price and payments

Radical Fat Loss is a membership. It offers two auto-renewable subscriptions in a single group — a monthly plan and an annual plan. At launch both are offered at founding rates: €4.99 per month and €29.99 per year (the base price is in euros; Apple shows and equalises the price for your storefront). We never ask you for payment details and do not handle them at all: the subscription is sold and billed by Apple through your Apple Account, at the price shown and confirmed at the point of purchase.

A 14-day free trial comes first. New users get 14 days of full access, free. The trial is managed by the App itself, so no payment sheet appears when you install and nothing is charged during it. If you don't subscribe by the end of the trial, the App becomes read-only: your data stays on your device and you can always view and export it, while new logging and coaching pause until you subscribe.

Auto-renewal and cancellation. A subscription renews automatically at the end of each period unless you cancel. You can cancel at any time, in one tap, from your Apple subscription settings (on your device: Settings → your name → Subscriptions) — there is no email to send and no retention flow. Cancelling stops the next renewal; you keep access until the end of the period you have already paid for, after which the App becomes read-only with viewing and export still available. Deleting the App does not cancel a subscription — cancel it in your Apple settings.

The Active rate — a lower price you earn by training. Each plan has its standard rate and a lower “Active” rate — at founding prices, €3.99 per month or €19.99 per year. You earn it by using the App for what it is for:

• Your first paid period is at the Active rate, automatically. Every new subscriber's first month, or first year, is billed at the Active rate. You don't have to earn the first one — it is applied for you as an introductory offer.
• After that, you earn each period. Record an active day — any day you log food, weight, or a workout — on 12 or more days in a billing month, and your next month is billed at the Active rate. On the annual plan, reach that bar in 10 of the 12 membership months and your next year is billed at the Active rate.
• A tap applies it — nothing reprices on its own. When you have earned it, the App offers the lower rate and you tap to apply it through the standard Apple purchase sheet; Apple then bills the Active rate at your next renewal. If you don't apply it, or don't reach the bar, that period simply renews at the plan's standard rate. Missing a period is never a penalty — you can earn the rate right back the next period.
• Eligibility is worked out on your device. Whether you have hit the bar is computed on your iPhone, from your own log, and is never uploaded. Applying the rate sends only your subscription's purchase details to our signing service (Privacy Policy §6.5) — never your health data, and never whether or how you have trained.

Founding rates are locked for as long as you stay. The founding prices above are yours for as long as your membership continues without lapsing. When the founding window closes, prices rise for new members only — your founding rate stays: automatically, with no action from you, on the plan you are on — and if you later switch between the monthly and annual plans, you keep it by making the same one-tap claim at each renewal.

We may change prices for the future; where we do, we will show the new price and, where the law requires, obtain your consent before it applies, and an increase never applies to a period you have already paid for. Nothing in this section limits any mandatory statutory rights you have as a consumer under EU or local law, including any right to a refund. Refunds for App Store purchases are handled by Apple under the Apple Media Services Terms and Conditions, via reportaproblem.apple.com.

7AI features & third-party services

The coach and the type-a-meal parser run on your iPhone where the hardware supports Apple's built-in on-device model. Cloud AI is optional and off by default: photo and menu reading and the cloud coach become available only after you enable them behind an explicit, revocable consent, and only on profiles aged 18 or older (§3). Cloud responses are generated by the AI provider, Anthropic, PBC; exactly what is sent, and when, is set out in the Privacy Policy §6.1.

Cloud AI uses your own API key: you paste a key from your own Anthropic account and the App talks to the provider directly — no server of ours sits in that path. Your use of the AI service is then also governed by your own agreement with that provider, including its terms and its pricing, and any charges the provider bills to your account are your responsibility. Without a key, every AI feature runs on the on-device model or a manual path.

AI output is an estimate, not a measurement: photo macro reads and coach answers may be incomplete or wrong (§11). The App presents them for you to check and edit, not to obey.

The App also queries one further third party: Open Food Facts, when you scan a product barcode, and only with the barcode number. It also downloads a public food-composition dataset to keep its offline database current. Your use of such services is governed by their own terms; we don't control them and aren't responsible for their availability or output. What each feature sends, and when, is described in our Privacy Policy.

8Your data & privacy

Radical Fat Loss is local-first: your profile, logs, weight, and the health data the App reads live on your device. Your app content also syncs through your own Apple iCloud account (Apple's CloudKit), under your Apple ID and Apple's terms, so it reaches your devices and survives a reinstall — this is your iCloud, not a server we operate, sensitive fields are end-to-end encrypted, and the data read from Apple Health is excluded from it; you can turn it off in iOS Settings. We don't run a server that stores your app data, and we never sell your data. How we handle data — including the optional features that send something to us or a third party, iCloud sync, and your GDPR rights — is set out in full in our Privacy Policy, which forms part of these Terms. You are responsible for keeping your own backups; if you delete entries or the App, the related local data is removed.

9Acceptable use

You agree to use the Service lawfully and not to:

• break the law, infringe others' rights, or misuse the Service to harm anyone;
• interfere with, disrupt, or attempt to gain unauthorised access to the Service or its systems;
• introduce malware, scrape at scale, or circumvent security or usage limits;
• use the Service to provide medical, dietary, or clinical advice to others as if it were a professional service.

10Intellectual property

The Service — including the App, the Site, our software, design, text, logos, and the "Radical Health" and "Radical Fat Loss" names and marks — is owned by Radical Health OÜ or its licensors and is protected by intellectual-property laws. These Terms grant you no rights to our trademarks or branding. Any content you create stays yours; because it lives on your device, you retain full control of it.

11Disclaimers

We work hard to make the Service useful and honest, but to the fullest extent permitted by law it is provided "as is" and "as available," without warranties of any kind, whether express or implied, including fitness for a particular purpose, accuracy, or uninterrupted availability. The App's calculations, estimates, and insights — including AI- and photo-based ones — may be incomplete or wrong, and are for general information only. This section does not exclude any warranty or right that cannot be excluded under applicable consumer law.

12Limitation of liability

To the fullest extent permitted by law, Radical Health OÜ will not be liable for any indirect, incidental, special, or consequential damages, or for any loss of data, profits, or goodwill, arising from your use of (or inability to use) the Service. Our total liability for any claim relating to the Service is limited to the amount you paid us for it in the 12 months before the event giving rise to the claim.

Nothing in these Terms limits liability that cannot be limited by law — including liability for death or personal injury caused by negligence, for fraud, or under your mandatory consumer-protection rights. Some jurisdictions don't allow certain limitations, so some of the above may not apply to you.

13Suspension & termination

You may stop using the Service at any time. You can cancel the membership in your Apple subscription settings (§6): it will not renew, you keep access until the end of the period you have already paid for, and the App then becomes read-only with your data still viewable and exportable. You can also delete the App at any time; deleting it does not by itself cancel a subscription. We may suspend or end your access if you materially breach these Terms or use the Service in a way that risks harm to others or to the Service, giving notice where reasonable and proportionate. Sections that by their nature should survive termination (such as §10–§12, §14, and §15) continue to apply.

14App Store — additional terms

You obtained the App through the Apple App Store. The following apply to that distribution and, in case of any conflict with the rest of these Terms for App Store matters, prevail:

• This agreement is between you and us, not Apple. Radical Health, not Apple, is solely responsible for the App and its content.
• Scope of licence. The licence in §4 is non-transferable and limited to use on Apple-branded products you own or control, per the App Store Usage Rules.
• Maintenance and support. We are solely responsible for any maintenance and support for the App. Apple has no obligation to provide it.
• Warranty. We are solely responsible for any product warranties, whether express or implied. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any) of the App; to the maximum extent permitted by law, Apple has no other warranty obligation regarding the App.
• Product claims. We, not Apple, are responsible for addressing any claims relating to the App, including product-liability, regulatory, and consumer-protection claims, and claims that the App fails to conform to legal or regulatory requirements.
• Intellectual-property claims. If a third party claims the App infringes its intellectual-property rights, we (not Apple) are responsible for the investigation, defence, settlement, and discharge of that claim.
• Legal compliance. You represent that you are not located in a country subject to a U.S. Government embargo or designated "terrorist-supporting," and that you are not on any U.S. Government list of prohibited or restricted parties.
• Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right to enforce them against you.

15Governing law & disputes

These Terms are governed by the laws of Estonia, and disputes fall to the competent courts of Estonia — except where the mandatory consumer-protection law of your country of residence in the EU/EEA grants you stronger protection or a different forum, in which case those rights are preserved. As an EU consumer, you may also use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr. We're usually glad to sort things out directly first — email hello@radicalhealth.app.

16Changes to these terms

We may update these Terms as the Service evolves. We'll post the new version here with an updated effective date and, for material changes, give reasonable notice (for example, in the App). Changes don't apply retroactively, and your continued use after they take effect means you accept them. If you don't agree to a change, stop using the Service.
