Effective 12 July 2026
These terms govern your use of the Mavlo application and website (mavlo.io), operated by Mavlo Ltd, a company registered in England and Wales and based in Newcastle upon Tyne, United Kingdom ("Mavlo", "we", "us", "our"). By creating an account or using Mavlo, you agree to these terms. If you do not agree, do not use the service.
Mavlo is a fitness accountability service. You voluntarily create weekly fitness commitments — such as gym visits, runs, or activity targets — and attach an amount to each commitment that is charged only if your week is incomplete. Your activity is verified automatically through sources you connect, such as your gym's attendance records or Strava. If you complete your commitment, nothing is charged. If you miss it, the pledged amount is charged to your card as a missed-commitment fee.
Missed-commitment fees are platform fees payable to Mavlo. They are not external-cause payments or speculative financial products, and Mavlo does not route them to any external organisation.
Public gym research tester. You can use the tester without a Mavlo account. It is a provider-compatibility research tool, not account verification, and it never completes or fails a commitment or causes a charge. Planet Fitness and Crunch sign-in takes place on the selected provider's website. For a JD Gyms test, you authorise Mavlo to send the credentials you enter once to the selected JD Gyms member service and retrieve the attendance window shown; Mavlo does not save or log the credentials or resulting provider session. Visit rows are processed only long enough to validate the provider format and are never retained or logged; only the sanitised attempt summary is stored. A provider appearing in the tester does not mean that Mavlo is partnered with or endorsed by it, or guarantee that an integration will work.
You must be at least 18 years old to use Mavlo, because the service involves financial transactions. By creating an account you confirm that you are 18 or over, that the information you provide is accurate, and that you are authorised to use the payment card you save.
Correctly-charged missed-commitment fees are non-refundable. The fee is the agreed consequence of a commitment you set yourself and did not complete; if the verification was accurate, the charge is valid and final. This is the core of the service, not a penalty imposed on you — you choose the commitment, the target, and the amount.
Every charge shows the amount, the reason, the date, the related commitment, and comes with a receipt.
If you believe a fee was charged in error — for example, you completed the activity but a verification source failed, returned wrong data, or Mavlo mis-matched it — you can raise a dispute in the app or by emailing hello@mavlo.io within 14 days of the charge. While a dispute is open, no further related charges are taken. If we find the error was on Mavlo's side or in the verification chain, the fee is refunded in full. Disputes are reviewed fairly: the question is whether you actually completed the commitment, not whether the system says you did.
Mavlo membership is billed through Apple In-App Purchase at the price displayed in the app at the time of purchase (currently £9.99 per month for the monthly plan), and is required before you can run active paid commitments. You can cancel at any time in your App Store subscription settings; your access continues until the end of the current billing period. Subscription payments for the current period are non-refundable by Mavlo, though Apple's own refund process may be available to you.
While Mavlo is in TestFlight beta:
Commitments run for the duration you choose when you create them. Fees already incurred for completed weeks remain valid if you stop using the service. If genuine circumstances prevent you from fulfilling a commitment — serious illness or injury, significant hardship, or your gym closing — email hello@mavlo.io and we will review your case individually.
You agree not to:
Mavlo includes social features (groups and friends) where the names and content you enter are visible to other members. There is zero tolerance for objectionable content or abusive behaviour. You agree not to post, use, or share content — including group names, display names, or any other text — that is hateful, harassing, threatening, sexually explicit, discriminatory, or otherwise objectionable, and not to harass, bully, or abuse other members.
You can report content or a member, and block any member, from within the app. We review reports and act on objectionable content and abusive users — typically within 24 hours — including removing content and suspending or terminating accounts. We also filter obviously objectionable names automatically. By using the social features you agree to these terms; there is no obligation to accept them, but they are required to use those features.
We may suspend or terminate your account if you breach these terms, attempt to manipulate verification, or use the service abusively or fraudulently. You may stop using Mavlo and delete your account at any time in the app. Termination by either side does not cancel fees that were validly incurred before termination, and does not affect your right to dispute any charge under Section 5.
Mavlo is an accountability tool, not a medical or coaching service. Nothing in the app is medical advice. You are responsible for ensuring the commitments you set are safe for you; consult a doctor before starting a new exercise programme if you have any health concerns.
The service is provided "as is". To the extent permitted by law, we are not liable for gym or provider system outages, delays in payment processing by Stripe, inaccurate data supplied by third-party sources (your remedy for a resulting wrong charge is the dispute process in Section 5), or indirect or consequential losses. Our total liability to you is limited to the amounts you have paid to Mavlo in the 12 months before your claim.
Nothing in these terms excludes or limits liability that cannot be excluded under the law of England and Wales, including liability for death or personal injury caused by negligence, fraud, or your statutory rights as a consumer.
We may update these terms from time to time. Changes will be posted on this page with an updated effective date, and we will notify you of material changes in the app or by email. Material changes to fees or charging do not apply to commitments already running until they end.
These terms are governed by the laws of England and Wales, and disputes are subject to the jurisdiction of the courts of England and Wales. If you live elsewhere in the UK, you keep any mandatory consumer protections of your home nation.
Operator: Mavlo Ltd, a company registered in England and Wales, Newcastle upon Tyne, United Kingdom.
