Terms & Conditions
Last updated: 11 September 2026
1. Acceptance of these Terms
These Terms & Conditions ("Terms") form a binding agreement between you and ProLyft, operated by MuscleHealth OÜ, a company registered in Estonia under registry code 17596698 ("we", "us"). You can reach us at support@prolyftapp.com. Depending on the store you download from, ProLyft may be listed under a different seller name; the company named above is the operator in every case. They cover the ProLyft mobile app, our website at prolyftapp.com and any related services we provide. By creating an account or using the app or the website, you confirm that you have read, understood and accepted these Terms and our Privacy Policy, which forms part of them. If you do not agree, please do not use ProLyft.
2. Eligibility
ProLyft is designed for adults and teenagers, and the minimum age for an account is 13. It is not directed at young children and we do not market it to them. Some countries in the EU and EEA set a higher age — up to 16 — for agreeing to a service like this on your own; if you are below the age that applies where you live, you can use ProLyft with a parent's or guardian's consent. Section 15 of the Privacy Policy sets out the age rules in full, what happens if we learn that an account belongs to a child below the age that applies, and how a parent or guardian can have it removed. The app keeps a record of your training and, if you enter them, your body metrics, so use it only if you understand what keeping that kind of record means. Whatever your age, loaded barbell work is not something to learn alone — we strongly recommend that younger lifters train under the supervision of a qualified adult. By registering you confirm that the information you give us is accurate and that you keep it up to date.
3. Your account
You can create an account with an email address and password, or sign in with Google or Apple. One person, one account. When you register with an email address we send you a verification link, and you can request a fresh one from Profile → Settings — subject to a rate limit that protects against automated abuse, so several requests in quick succession may be declined for a while. Verifying is entirely optional: nothing in ProLyft is locked behind it and nothing ever will be — your account works in full from the moment you create it, whether you verify or not. What verifying does is prove that the address really reaches you, which is what our password-reset and account-recovery mail depends on; if we cannot reach you there, we may not be able to get you back into your account. If you sign in with Google or Apple, they have already confirmed your address to us and there is nothing for you to do. Please register with an address you actually control, and keep it up to date. You are responsible for keeping your credentials secure and for all activity that happens under your account. Notify us immediately at support@prolyftapp.com if you suspect unauthorised use.
4. Free tier, subscriptions and refunds
The core features of ProLyft are free to use. Some advanced features are (or will be) offered as part of a paid subscription billed through the Apple App Store or Google Play. Payment is taken by Apple or Google, never by us — we never see your card details. We use RevenueCat to keep track of which subscription your account holds; it does not bill you either, and your card details never reach it. Subscriptions renew automatically unless cancelled in your store account settings at least 24 hours before the end of the current billing period, and a free trial converts to a paid subscription unless cancelled before it ends. Refunds are handled under the App Store or Google Play refund policies, so please contact them rather than us. If you are a consumer in the EU or EEA you have a 14-day right of withdrawal for digital purchases, which you may lose once delivery has begun with your agreement. If we ever change the price of a subscription, Apple or Google will tell you in advance and — for an increase — ask you to agree before it takes effect; you can cancel at any time before then.
5. Your content, sharing and licence
You keep ownership of what you create — your nickname, profile picture, custom exercises, routines, workout notes and training history. By using the social and sharing features you grant us a worldwide, non-exclusive, royalty-free licence to host, store, reproduce and display that content for the sole purpose of operating the app and showing it to the people you share it with. The licence ends when you delete the content or your account, except for copies others have already saved. Share cards are images generated on your device: they may carry your nickname and your training numbers, and once you post one outside ProLyft it is beyond our control. Your profile picture is served from a public web address — see section 9 of the Privacy Policy. You are responsible for what you post, and section 7 sets out the content and behaviour that are not allowed.
6. Reporting, blocking and moderation
There is no place in ProLyft for abusive users or objectionable content. You can block any user in the app, which removes the follow relationship in both directions and stops them interacting with you. To report a user — or their nickname, their profile picture, or anything else of theirs that reaches you in the app — open their profile and tap the flag icon: you can choose a reason and add a note, and the report reaches us directly. If something does not fit that form, or you want to send us more detail or evidence, email support@prolyftapp.com. Every report is reviewed, and we act on it within 24 hours of receiving it. Where a report is justified — or where we otherwise reasonably believe these Terms have been broken — we will remove the content and restrict or permanently close the account responsible. Section 11 sets out how suspension and closure work.
7. Acceptable use and prohibited content
You agree not to misuse ProLyft. In particular, do not: harass, bully, threaten or stalk anyone; post hateful content or content that attacks people for who they are; impersonate another person, a coach or ProLyft itself, or use a misleading or offensive nickname; post content that is unlawful, sexually explicit, or that promotes self-harm, disordered eating or the unsafe use of drugs; upload anything that infringes someone else's copyright, trademark, privacy or other rights; send spam, chain messages or unsolicited promotions; upload malware or anything designed to damage a device or our systems; attempt to access other users' data or accounts; probe, disrupt or overload our services; reverse engineer, decompile or tamper with the app; scrape or harvest content, including the exercise library, by automated means; create accounts by automated means, or sell, rent or share your account; or use ProLyft or anything in it commercially without our written permission. Content or behaviour of this kind can be reported as described in section 6.
8. Health and fitness disclaimer
ProLyft provides workout tracking and training guidance for informational and educational purposes only. It is not medical advice, it is not a medical device, and it is not a substitute for professional medical care, diagnosis or treatment. Nothing in the app — including tailored programmes, suggested loads, estimated one-rep maxes and progress statistics — is a clinical assessment. Consult a physician before starting or changing an exercise programme, especially if you are pregnant, have a heart condition, an injury, a chronic illness or take medication. Stop immediately and seek medical attention if you feel pain, dizziness, chest tightness or unusual shortness of breath. Never disregard professional medical advice because of something you saw in the app.
9. Assumption of risk
Resistance training carries an inherent risk of injury. By using ProLyft you accept that risk and agree that you alone are responsible for your safety: for training within your ability, for your technique, for warming up, for the condition and correct use of your equipment, and for deciding whether a suggested exercise, weight or programme is appropriate for you. Suggested loads and progressions are estimates calculated from the numbers you enter — they are suggestions, not instructions, and you should always reduce or skip anything that does not feel safe. Use a spotter where appropriate. Results vary between individuals and we do not guarantee any particular strength, fitness or body-composition outcome.
10. Intellectual property and trademarks
The app, the website and all content we provide (including the exercise library, illustrations, animations, text and training programmes) are owned by us or our licensors and are protected by copyright and other intellectual-property laws. "ProLyft", the ProLyft logo and our other names, marks, slogans and visual identity are our trademarks. You may not use them as your own, in a way that suggests we endorse or are connected with you, or in any confusingly similar form, without our written permission. You may not copy, modify, translate or distribute our content except as these Terms allow. None of this affects your ownership of your own content under section 5.
11. Suspension, termination and account deletion
You can delete your account at any time in Settings. Deletion is reversible for 7 days: signing back in within 7 days restores your account and data; after 7 days everything is permanently erased, as described in the Privacy Policy. We may remove content and suspend or permanently close your account if you breach these Terms — immediately and without prior warning where the breach is serious, such as harassment, unlawful content, infringement of someone else's rights, or an attempt to compromise the service. Where it is proportionate we will warn you first and give you a chance to put things right. Signing out also clears your training data from the device, subject to one exception, explained in section 7 of the Privacy Policy. Copies may also remain in backups you make of your own phone.
12. Changes to the app
ProLyft is under active development. We may add, change and improve features over time. If we remove or materially reduce a feature you rely on, we will give reasonable notice in the app beforehand, except where we have to act immediately for security or legal reasons. Features clearly marked as experimental or preview may change or disappear at any time. If a change materially reduces a paid feature you have already paid for, we will tell you in advance and, where the law requires it, offer a pro-rata refund. We may also occasionally take the backend offline for maintenance. Because ProLyft stores your training data on your device first, the app keeps working while that happens — you can log workouts as normal and they sync once the backend is back. Signing in does need a connection, though, so if you are signed out during maintenance or an outage you will not be able to sign back in until it is over. We are not responsible for interruptions caused by events outside our reasonable control.
13. Third-party links, disclaimer and limitation of liability
ProLyft may link to websites, stores and services we neither own nor control. Those links are there for convenience, they are not an endorsement, and once you follow one you are covered by that third party's terms and privacy policy rather than ours; we are not responsible for their content, products or practices. The app itself is provided "as is" and "as available", without warranties of any kind. To the maximum extent permitted by law, we are not liable for indirect, incidental or consequential damages, for injuries or health outcomes arising from exercise you choose to perform, or for lost, corrupted or unsynced workout data — keep your own records if that data matters to you. Where liability cannot be excluded, it is limited to the amount you paid us in the twelve months before the event. Some things can never be excluded, whatever this document says: we remain fully liable if our negligence causes death or personal injury, and for fraud. And none of the above reduces the rights the law gives you as a consumer — if a term here conflicts with those rights, your rights win.
14. Your responsibility to us
If your use of the app breaks these Terms or the law and that leads to a third-party claim against us, you agree to cover the reasonable costs of dealing with it, to the extent the claim results from your own actions. This does not apply to claims caused by our acts or omissions, and it does not limit any statutory consumer rights you have.
15. Changes to these Terms
We may update these Terms from time to time. Material changes will be announced in the app at least 14 days before they take effect, and the date at the top of this page will change. Continued use after that means you accept the updated Terms; if you do not accept them, you can delete your account in Settings.
16. Governing law, disputes, assignment and general terms
These Terms are governed by the law of the Republic of Estonia and the Estonian courts have jurisdiction, without affecting the mandatory consumer-protection rules of the country where you live or your right to bring a claim before your local courts where the law allows. If you are a consumer and we cannot settle a complaint between us, you may refer it to the Consumer Disputes Committee at the Estonian Consumer Protection and Technical Regulatory Authority (Tarbijakaitse ja Tehnilise Järelevalve Amet, ttja.ee), or to the alternative dispute resolution body in your own country. We may transfer or assign these Terms, in whole or in part, to another company — for example if ProLyft is sold, merged or reorganised — provided your rights under them are not reduced; you may not transfer your account or your rights under these Terms to anyone else. If any clause is held invalid, the rest remains in force. These Terms are the entire agreement between us about ProLyft, and our not enforcing a term on one occasion is not a waiver of it.
17. Contact
Questions, complaints, reports and legal notices: email us at support@prolyftapp.com and we will reply as soon as we reasonably can. The company behind ProLyft, its registry code and its postal address are in section 1.
