Flex Scale & Fast Terms of Use

Effective date: 14 September 2026

Back to Flex Scale & Fast

These terms are an agreement between you and Elixir Consultancy Services Ltd ("ElixirCS", "we", "us") about your use of the Flex Scale & Fast app. We are registered in England and Wales under company number 05821983.

By downloading or using Flex Scale & Fast, you agree to these terms. If you don't agree, please don't use the app. The App Store's own terms also apply.

Our Website Terms of Use apply separately to the website. Please also read the Flex Scale & Fast Privacy Policy, which explains how the app handles your information.

Who can use the app

Flex Scale & Fast is for adults. You must be 18 or over and legally able to agree to these terms.

Your licence

We give you a personal, non-exclusive, non-transferable and revocable licence to install and use Flex Scale & Fast on Apple devices that you own or control, as allowed by the Usage Rules in the App Store's terms. You don't become the owner of the app. The app is free to download and use.

Health information

  • Flex Scale & Fast helps you record and look back at your own weight, fasts, sleep and activity. It isn't a medical device. It doesn't give medical advice, and it doesn't diagnose or treat anything.
  • Charts, trends, estimates and wins describe what you and Apple Health have recorded. They don't show what caused a change, and they aren't a promise of future results.
  • Fasting and changing your weight aren't right for everyone. Talk to a doctor or another qualified health professional before you start, especially if you have a health condition, take medication, are pregnant or breastfeeding, or have had an eating disorder.
  • Stop fasting and get medical help if you feel unwell.
  • The app can only be as accurate as the readings it's given, such as those from your scale, your other devices and Apple Health.

Your data

  • Your fasts, the weights you add, your goals and your height are stored only on your iPhone. We don't have a copy and can't recover them for you.
  • They aren't included in iCloud or in iPhone backups. If you delete the app, erase your iPhone or move to a new one without exporting them first, they will be lost.
  • Use Export my data in the app's Settings to keep your own copy. You are responsible for keeping exported files safe.
  • Data from Apple Health stays in Apple Health. What the app can show depends on what is in Apple Health and what you allow the app to read.

Acceptable use

You must not use Flex Scale & Fast to:

  • break the law, or infringe anyone's privacy, copyright or other rights;
  • try to gain unauthorised access to the app or to our systems;
  • introduce malicious code, or disrupt the app or anyone else's service;
  • reverse engineer, decompile, disassemble or modify the app, except where the law doesn't allow us to prevent this; or
  • remove or change legal, copyright or ownership notices.

Apple users

Flex Scale & Fast is distributed through Apple's App Store, and Apple's Standard End User Licence Agreement also applies. If these terms conflict with Apple's mandatory App Store terms, Apple's terms apply to the extent of the conflict.

Apple requires us to tell you the following:

  • These terms are between you and Elixir Consultancy Services Ltd only, and not with Apple. Apple is not responsible for Flex Scale & Fast or its content.
  • Apple has no obligation to provide any maintenance or support for Flex Scale & Fast.
  • If Flex Scale & Fast fails to meet any applicable warranty, you may tell Apple, and Apple will refund the purchase price of Flex Scale & Fast to you, if there was one. To the maximum extent the law allows, Apple has no other warranty obligation for Flex Scale & Fast.
  • Elixir Consultancy Services Ltd, not Apple, is responsible for dealing with any claims about Flex Scale & Fast or your use of it, including product liability claims, claims that it fails to meet a legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
  • If anyone claims that Flex Scale & Fast, or your possession and use of it, infringes their intellectual property rights, Elixir Consultancy Services Ltd, not Apple, is responsible for investigating, defending, settling and discharging that claim.
  • You confirm that you are not located in a country that is subject to a US Government embargo, or that has been designated by the US Government as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
  • Questions, complaints and claims about Flex Scale & Fast should be sent to support@elixircs.com, or by post to Elixir Consultancy Services Ltd, 7 Croftflat Drive, Fenay Bridge, Huddersfield, HD8 0FS, United Kingdom.
  • You must follow any third-party terms that apply when you use Flex Scale & Fast.
  • Apple and its subsidiaries are third-party beneficiaries of these terms. Once you accept these terms, Apple has the right to enforce them against you as a third-party beneficiary.

Updates and changes

We may release updates to keep the app secure, compatible and working well. Flex Scale & Fast may stop working on devices, or on versions of iOS, that we no longer support. We may make reasonable changes to the app, including for legal, security or technical reasons. Exporting your data from time to time means you always have your own copy.

Things we don't control

Flex Scale & Fast depends on things we don't control, including Apple Health, iOS updates, and the scales, watches and other apps that save data to Apple Health. We can't promise the app will always work without interruptions or errors. This doesn't affect any rights you have by law.

Intellectual property and trademarks

Flex Scale & Fast, this website and their content, design and code belong to ElixirCS or are licensed to us. Apple, Apple Watch and iPhone are trademarks of Apple Inc., registered in the U.S. and other countries. Flex Scale & Fast is an independent app and is not made, endorsed or sponsored by Apple.

Your consumer rights

Flex Scale & Fast is provided "as available". To the extent the law allows, we don't make promises beyond those in these terms. Nothing in these terms takes away rights you have by law, including your right as a consumer to digital content that is as described, fit for purpose and of satisfactory quality.

Limitation of liability

We are responsible for loss or damage you suffer that is a foreseeable result of us breaking these terms or failing to use reasonable care and skill. We are not responsible for loss or damage that isn't foreseeable, for loss caused by things outside our reasonable control, or for business losses if you use the app for personal purposes.

Decisions about your eating, fasting, exercise and health are yours to make. Where you need to, make them with the help of a qualified professional.

Nothing in these terms limits our liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that can't be limited by law.

Ending these terms

You can stop using Flex Scale & Fast at any time. We may suspend or end your right to use it if you seriously or repeatedly break these terms. Where it's reasonable, we will tell you first and give you a chance to put things right. We may act straight away if we need to protect people, systems or our rights, or to follow the law. Rights you already have, including consumer remedies, stay in place.

Changes to these terms

We may update these terms for legal, security, technical or business reasons. We will publish the new version here with a new effective date. If a change is significant, we will give you reasonable notice where we can. If the law requires your agreement to a change, we will ask for it.

Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you are a consumer living elsewhere, you keep any mandatory rights under the law of your country, and you can bring proceedings in your local courts.
