Terms of Use
Last updated 8 October 2026
These terms are the agreement between you and Sport Star Management LLC for the use of Landau — the ideal figure (“Landau”). They cover what the app does, what it is not, how the one-time purchases work and what each of us is responsible for.
1.Agreement
Landau — the ideal figure is operated by Sport Star Management LLC (OOO «Sport Star Management», OGRN 1097746525898), a company registered in the Russian Federation, with its registered office at 34 Verkhnyaya Krasnoselskaya Street, Moscow, 107140, Russia (“we”, “us”).
By downloading, installing or using Landau — the ideal figure, you agree to these terms. If you do not agree, do not use the app. Our handling of personal data is described in the Privacy Policy, which forms part of this agreement.
2.Eligibility
You must be at least 16 years old and able to enter a binding contract where you live. If you are using Landau — the ideal figure on behalf of an organisation, you confirm you are authorised to bind it to these terms.
3.Your account
Landau has no accounts. Purchases are tied to your Apple ID: Restore Purchases on a new device reattaches them. Your measurements are stored only on your device; back it up if you want to keep them.
4.What Landau — the ideal figure is, and is not
Landau is a tribute to the physicist Lev Landau: it applies his half-serious formula of attractiveness to five measurements, keeps your history, offers tips and a chart of famous figures to compare with.
Landau is entertainment, not health, nutrition or medical advice. The coefficient is a historical curiosity with no scientific or medical validity, and the tips are general remarks, not a programme. Do not change your diet or exercise on the strength of a number in this app; talk to a doctor.
5.Acceptable use
You must not:
- Attempt to gain access to another user's account, data or key material.
- Probe, scan or test the vulnerability of our systems without our prior written consent, or otherwise interfere with their operation.
- Use automated means to create accounts or place load on the service beyond normal app use.
- Reverse engineer, decompile or disassemble the app, except to the extent that applicable law expressly permits it despite this restriction.
- Resell, sublicense or make the service available to third parties as your own.
We may suspend or terminate an account that breaches this section.
6.Purchases
Landau is free to download. The first calculations are free, and sharing a result unlocks the full calculation for free. Packs of further calculations are one-time purchases. The exact price for your region and currency is shown on the purchase screen before you confirm.
Payment is charged to your Apple App Store account on confirmation of purchase; we never receive or handle your payment details. One-time purchases do not renew. Restore Purchases in the app reattaches them to a new device signed in with the same store account.
Refunds are handled by Apple under its own policies. We cannot issue a refund for a store purchase. Where you have a statutory right of withdrawal under consumer law in your country, that right is unaffected by this section.
7.Apple App Store
Where you obtained Landau — the ideal figure from the Apple App Store, the following applies and prevails over anything inconsistent elsewhere in these terms:
- This agreement is between you and Sport Star Management LLC only, not with Apple. We, not Apple, are solely responsible for Landau — the ideal figure and its content.
- Apple has no obligation to furnish any maintenance or support for Landau — the ideal figure.
- If Landau — the ideal figure fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever.
- Apple is not responsible for addressing any claim by you or a third party relating to Landau — the ideal figure, including product liability, failure to conform to legal requirements, and consumer protection or privacy claims.
- Apple is not responsible for the investigation, defence, settlement or discharge of any third-party claim that Landau — the ideal figure infringes intellectual property rights.
- You confirm you are not located in a country subject to a U.S. Government embargo or designated as “terrorist supporting”, and that you are not on any U.S. Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these terms and, upon your acceptance, will have the right to enforce them against you.
8.Availability
We aim to keep Landau — the ideal figure available, but we do not guarantee uninterrupted service. We may suspend it for maintenance, and we may change or discontinue features. If we discontinue the service altogether, we will give you reasonable notice in the app or by any other means we have.
9.Termination
You may stop using Landau — the ideal figure at any time. We may suspend or terminate your access if you breach these terms, if we are legally required to, or if continuing would expose us or other users to material risk. Except where a breach makes it inappropriate, we will give notice first.
10.Disclaimers
To the fullest extent permitted by law, Landau — the ideal figure is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose and non-infringement.
We do not warrant that Landau — the ideal figure will be uninterrupted or error-free, or that the coefficient or the tips have any medical, nutritional or scientific value.
Nothing in these terms excludes or limits liability that cannot lawfully be excluded, including liability for death or personal injury caused by negligence, and for fraud. If you deal as a consumer, your statutory rights are unaffected.
11.Limitation of liability
Subject to the section above, to the fullest extent permitted by law:
- We are not liable for indirect, incidental, special, consequential or punitive loss, or for loss of profit, revenue, goodwill or anticipated savings.
- We are not liable for any health outcome resulting from treating the app's result or tips as advice.
- Our total aggregate liability arising out of or in connection with these terms is limited to the greater of (a) the amount you paid us in the 12 months before the event giving rise to the claim, and (b) 50 EUR.
12.Changes to these terms
We may update these terms. The date at the top reflects the current version. Where a change materially affects your rights, we will give notice in the app before it takes effect. Continuing to use Landau — the ideal figure after that point means you accept the change; if you do not, stop using the app.
13.Governing law
These terms are governed by the law of the Russian Federation, and disputes are resolved by the competent courts of the Russian Federation. If you are a consumer resident elsewhere, this does not deprive you of the protection of mandatory consumer law in your country of residence, nor of the right to bring proceedings there.
