Terms of Service

Effective date: 28 July 2026

Short version: Optimally tells you what’s in your food based on public ingredient data. It’s an information tool, not medical advice, and the data isn’t perfect — always check the physical label, especially for allergies. Optimally is a paid subscription billed by Apple, and you cancel it in iOS Settings.

1. Who these terms are between

These terms are an agreement between you and Nathaniel Fiskå (“we”, “us”), a sole trader based in Norway, operator of the Optimally iOS app and this website. Contact: nathanielfiska@gmail.com.

By downloading or using Optimally, you agree to these terms. If you don’t agree, don’t use the app.

2. Apple’s terms also apply

Optimally is distributed through the App Store, so Apple’s Licensed Application End User License Agreement also applies to your use of the app. Where these terms and Apple’s standard EULA genuinely conflict, Apple’s EULA governs your licence to use the software.

You acknowledge that Apple is not a party to these terms, has no obligation to provide support for Optimally, and that any claim about the app itself is between you and us — not you and Apple. Apple is, however, a third-party beneficiary of these terms and may enforce them against you.

3. Your licence to use Optimally

We grant you a personal, non-transferable, non-exclusive licence to use Optimally on Apple devices you own or control, for your own non-commercial use. You may not sell, rent, sublicense or redistribute the app; reverse-engineer, decompile or otherwise attempt to extract its source code except where that restriction is prohibited by law; or scrape, bulk-extract or resell the scores and ratings it produces.

4. What Optimally is — and what it is not

Optimally reads publicly available ingredient data and applies a fixed set of published rules to produce a score. That’s it. Specifically:

Optimally is not medical, nutritional or dietary advice. It does not diagnose, treat, cure or prevent any condition. If you have a medical condition, are pregnant, or are making a significant change to your diet, speak to a qualified professional.
Optimally is not an allergen check. Never rely on it to decide whether a product is safe for an allergy or intolerance. Database records can be incomplete, out of date, or wrong, and manufacturers change recipes without notice. Always read the physical packaging.
Scores are our opinion, expressed consistently. They reflect a published set of rules and the research we cite for each one. Reasonable experts weight these factors differently, and other apps will score the same product differently on purpose.

5. Product data comes from third parties

Product information comes from Open Food Facts and Open Beauty Facts, open databases built by volunteers and licensed under the Open Database License (ODbL). Recall information comes from openFDA, published by the U.S. Food and Drug Administration.

We don’t control that data and we don’t guarantee it is accurate, complete or current. If a product’s entry is wrong, the score built on it will be wrong too. Please tell us — see Support.

6. Subscriptions and billing

Optimally is a paid app. After the introductory questions, an active subscription is required to use it. There is no free tier and no ad-supported version.
Prices are shown in the app in your local currency before you buy, and all payments are processed by Apple through your Apple ID — we never see or handle your card details.
Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before the period ends. Apple charges your Apple ID at confirmation of purchase and at each renewal.
Free trials are offered where you are eligible — eligibility is determined by Apple, and someone who has already used an introductory offer in this subscription group will not be offered another. Where a trial is offered, its exact length and the price after it are shown before you confirm. Cancelling during a trial means you are not charged, but do it at least 24 hours before it ends, because Apple bills the moment it expires. Any unused portion of a trial is forfeited if you buy a subscription during it.
Cancel in iOS Settings → your name → Subscriptions → Optimally. Deleting the app does not cancel a subscription. Step-by-step instructions are on our Support page.
Refunds are handled by Apple, not by us — we have no ability to issue one. Request one at reportaproblem.apple.com.
We may change prices or what a subscription includes. A price change never applies to a period you’ve already paid for, and Apple will ask you to confirm before it takes effect on renewal.

7. Creator codes

We sometimes issue codes granting free access. Codes are for the person or audience they were issued to, and are not for sale or resale. We may invalidate a code in a future version of the app if it is published, shared at scale, or otherwise abused. A code has no cash value.

8. Acceptable use

Don’t use Optimally to break the law, don’t try to disrupt or overload our services or the third-party databases we rely on, don’t attempt automated or bulk access to any endpoint the app uses, and don’t misrepresent Optimally’s scores as a safety certification, a medical assessment, or an official rating of any kind.

9. Our content

The Optimally name, logo, design, scoring rules, written ratings and explanatory text are ours and are protected by copyright and trade mark law. Data sourced from Open Food Facts remains under the ODbL and is attributed as such. You’re welcome to share individual scores and score cards — that’s what they’re for.

10. Availability

We aim to keep Optimally working, but we don’t promise uninterrupted service. Features that depend on external services — product lookups, alternatives, recall checks — can fail when those services are down, and the app is designed to degrade gracefully when they do. We may change, suspend or discontinue features, and if we discontinue a paid feature entirely we’ll act reasonably about any subscription affected.

11. Disclaimers and liability

Optimally is provided “as is”. To the fullest extent permitted by law, we exclude implied warranties of merchantability, fitness for a particular purpose and non-infringement, and we are not liable for indirect or consequential loss, or for decisions you make based on a score.

Nothing in these terms limits liability that cannot lawfully be limited — including liability for death or personal injury caused by negligence, for fraud, or for any right you have as a consumer under Norwegian or EEA law. Where our liability can be limited, it is limited to the amount you paid us in the twelve months before the claim arose.

12. Ending this agreement

You can stop using Optimally and delete the app at any time. We may suspend or end your access if you materially breach these terms. Ending the agreement doesn’t automatically refund a subscription — that goes through Apple.

13. Changes to these terms

We may update these terms. We’ll change the effective date at the top, and for material changes we’ll flag it in the app. Continuing to use Optimally after a change means you accept the updated terms; if you don’t, stop using the app and cancel any subscription.

14. Governing law

These terms are governed by Norwegian law, and disputes fall to the Norwegian courts.

If you’re a consumer, this does not take away rights you have under the mandatory consumer law of your own country, and it does not stop you bringing a claim there. Consumers in Norway may also contact Forbrukerrådet (the Norwegian Consumer Council), and consumers in the EU may use the European Commission’s online dispute resolution platform.

15. General

If any part of these terms is found unenforceable, the rest continues to apply. Not enforcing a term isn’t a waiver of it. These terms, together with our Privacy Policy and Apple’s standard EULA, are the whole agreement between us about Optimally.

Optimally’s scores are an information tool, not medical advice. Always check the physical packaging for allergen information — only the label in your hand is authoritative.
