Companion documents: the Privacy Policy says what happens to your data (in short: it stays on your phone); the Purchase Terms cover the one-time purchase.
1. Who we are and what this is
LEVR is an Android app for logging strength training and tracking markers such as sleep or mood alongside it. It is published by Adam Hájek ("we", "us"), contactable at .
LEVR is software you run, not a service we operate for you. There is no LEVR server and no account on our systems. You install a program; it runs on your phone; that is the whole of it.
By installing or using LEVR you agree to these terms. If you do not agree, do not use the app; uninstalling it removes everything it holds.
2. What you need
- An Android phone running Android 8.0 or later. We do not guarantee the app runs correctly on every device, Android version, or manufacturer software.
- No account. Signing in with Google is optional and unlocks nothing.
- You must be 16 or older. The app asks once, at first launch. If you are younger, you must not use LEVR.
- No network connection. The app works offline. A connection is needed only for the optional Google sign-in and for buying the unlock, both of which happen inside Google's own components.
3. Your data is yours
- Everything you create in LEVR — sessions, sets, markers, notes, photos — is yours. We claim no ownership and no licence over it, and we could not use it if we wanted to: we never receive it.
- We do not sell it, advertise against it, or train models on it. The Privacy Policy is the detailed statement and forms part of these terms.
- It lives on your device and you can delete it there at any time, including by uninstalling.
- We cannot recover it for you, and we are not responsible for its loss. Nothing backs it up — not us, and not Android's own backup, which is switched off for LEVR so that your logs are not copied to Google Drive. If you lose or reset your phone, clear the app's storage, or uninstall, the data is gone. Keeping your own records is your responsibility.
4. Your responsibilities
You agree not to:
- use LEVR in any unlawful way, or in breach of Google Play's terms;
- reverse engineer, decompile, modify or tamper with the app, except to the extent that applicable law expressly permits despite this restriction;
- circumvent, disable or interfere with the paid-feature boundary or with Google Play billing;
- copy, redistribute, resell, rent or sublicense the app or access to its paid feature.
5. Health, fitness and safety — read this
LEVR is a logging and analysis tool. It is not a medical device, it does not provide medical, diagnostic, therapeutic or professional advice, and it must not be used as a substitute for any of those.
- The correlations the app shows are statistical relationships in data you entered yourself. They describe your own records and nothing more. They are not diagnoses, not treatment or training recommendations, and not evidence that one thing caused another. A correlation between two markers can be a coincidence, a shared cause, or an artefact of how you logged.
- Strength training carries an inherent risk of injury. You decide what to train, how heavily, and whether to train at all. Those decisions and their consequences are yours alone, and you make them at your own risk.
- Consult a qualified professional before beginning or changing a training programme, and particularly if you have or suspect a medical condition, are injured, are pregnant, or are taking medication. Stop and seek medical attention if you experience pain, dizziness or any other symptom that concerns you. Do not delay seeking professional advice because of anything the app displayed.
- Nothing the app shows is validated for any clinical or diagnostic purpose, and the app does not monitor you, does not detect emergencies and cannot call for help.
To the fullest extent permitted by law, we accept no liability for any injury, health outcome, training result or decision arising from your use of LEVR.
6. No warranty
The app is provided "as is" and "as available", without warranty of any kind. To the fullest extent permitted by law we disclaim all warranties, express or implied, including any implied warranty of merchantability, satisfactory quality, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the app will be uninterrupted, error-free, free of defects, compatible with your device, or that any calculation, chart or statistic it displays is accurate, complete or suitable for any purpose.
We may change, suspend or discontinue any feature in future versions. You are never forced to update, and a version you have already installed keeps working on your phone.
Nothing in this section affects rights that mandatory consumer law gives you and that cannot be excluded or limited by agreement.
7. Limitation of liability
To the fullest extent permitted by law:
- we are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, loss of records, loss of profit, loss of opportunity, or business interruption, however caused;
- our total aggregate liability to you in connection with the app and these terms, on any basis, is limited to the amount you actually paid for the LEVR unlock in the twelve months before the event giving rise to the claim, or, if you paid nothing, to EUR 25;
- these limits apply even if a remedy fails of its essential purpose.
Nothing here excludes or limits liability that cannot lawfully be excluded or limited — including liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or under mandatory consumer protection law. If you are a consumer in the EU or EEA, your mandatory statutory rights apply whatever these terms say.
8. Ending it
Stop using LEVR whenever you like; uninstall it and nothing of yours remains. There is no subscription to cancel and no account to close. If you bought the unlock, the Purchase Terms §6 govern what happens to it.
Sections 3 to 7, 9 and 10 survive the end of these terms.
9. Changes to these terms
We change this document when the app changes. The app ships the current text inside itself (Settings → Legal & privacy) and the published copy is at https://stelnos.com/levr/terms. Continuing to use the app after a change means you accept the current version; if you do not accept it, uninstall the app. A change never reaches back into a purchase you have already made.
10. Law, disputes, and the rest
- Governing law: Czech law. If you are a consumer, this does not deprive you of the protection of the mandatory law of the country where you live.
- Courts: the courts of the Czech Republic, save that a consumer may also bring proceedings in the courts of their own country of residence, and mandatory local rules on jurisdiction apply.
- Severability: if any provision is held invalid or unenforceable, it is severed or read down to the minimum extent necessary, and the remaining provisions stay in force.
- No waiver: not enforcing a provision on one occasion does not waive it.
- Entire agreement: these terms, the Privacy Policy and the Purchase Terms are the whole agreement between us about the app, and replace any earlier draft or statement.
- For the purchase itself your counterparty is Google (see the Purchase Terms), so a payment dispute belongs with Google first. EU consumers may also contact their national consumer authority or a European Consumer Centre.
