Terms of use

Leanward iOS app · Effective: EFFECTIVE_DATE · Last updated: 27 September 2026

In plain words

  • Leanward is an information tool, not a doctor. It does not diagnose or treat anything, and it is not a medical device.
  • Its numbers are estimates. Some food data comes from an open, crowd-sourced database and can be wrong.
  • If you have a medical condition, take medication, are pregnant or breastfeeding, or have a difficult relationship with food, ask your doctor before starting a diet or a fast.
  • The app is for adults aged 18 and over, and is currently free.
  • These terms do not limit your statutory rights.

1. Who offers the app

Nimród Pöőr, a private individual (developer name: RustySleet)
Budapest, Hungary
E-mail: leanward.app@gmail.com

Called "we" below. We develop the app as a private individual, not as a business, and offer it free of charge. You download it from Apple's App Store; the App Store terms and Apple's standard end-user licence agreement govern the download and the licence. These terms add the points that follow from the app's health subject.

2. Accepting these terms

By downloading and using the app you accept these terms and the privacy policy. If you do not agree, do not use the app; you can delete it at any time.

The app is only for people aged 18 and over. During setup it does not accept a younger age.

3. What Leanward is for

Leanward helps you keep a record of what you eat and drink, which supplements you take, how your weight and body composition change, and when you fast. A training log will come in a later version. From your diary and your weight trend it estimates your energy expenditure and suggests calorie and macro targets.

The app is currently free, with no purchases and no ads. If a paid feature ever appears, its terms will be made clear before you buy.

4. Not medical advice, not a medical device

5. When to see a doctor

Talk to a doctor before you change your eating significantly, start fasting or take on much harder training, especially if you:

Stop fasting or dieting and get medical help if you feel dizzy, faint, have palpitations, severe weakness or confusion, or lose weight without explanation. In an emergency, call 112.

6. If your relationship with food is difficult

Counting calories and weighing yourself often is not good for everyone. If you notice that the numbers cause anxiety, guilt or compulsion, that you skip meals to "fit in", or that one "bad" number ruins your day, take a break from the app and talk to someone.

The app has no streaks, badges or motivational messages, so using it does not add pressure. If numbers weigh on you, turn on calm mode in Settings: you then log meals without calories, macros, a weight-loss goal or a weight trend, with support resources one tap away from Today. Calm mode can only be turned off by a deliberate choice in Settings.

7. Estimates and other people's data

8. Your part

9. Who owns what

The app, its name, logo and texts are our intellectual property. You receive a personal, non-exclusive, non-transferable licence to use the app; you do not buy it. Your data is yours; we acquire no rights in it. Third-party data is under its own licence (see section 7).

10. Availability and changes

We aim to keep the app working and up to date. Barcode lookup depends on Open Food Facts being available and needs an internet connection; the diary and the calculations work offline. We may develop the app, add features or remove them. If we stop developing it, the app already on your phone keeps working and you can export your data.

11. Liability

12. Governing law and disputes

Hungarian law governs these terms. If you live in another EU member state and the mandatory rules of your home country give you stronger protection, you keep that protection, and you may bring a claim before the courts where you live.

If you have a complaint, write to us at leanward.app@gmail.com; we reply within 30 days and try to settle it. If that fails, the competent Hungarian court decides, or, as set out above, the court where you live.

13. Apple's role

The app is licensed under Apple's standard end-user licence agreement; these terms add to it, and if the two conflict, Apple's licence agreement prevails. These terms are not Apple's: we are responsible for the app and its content, and Apple has no obligation to support the app.

14. Changes to these terms

When we change these terms, we update the date at the top of this page and announce material changes in the app in advance. If you do not agree with a change, you can stop using the app, exporting your data first.

15. Contact

Questions, bugs or complaints: leanward.app@gmail.com. Frequent questions: Support.

Effective: EFFECTIVE_DATE. These terms also exist in Hungarian; if the two differ, the Hungarian version prevails.
