Terms & Conditions

Last updated: 6 October 2026

About Khilo & Acceptance of These Terms

Khilo is a weight-lifting tracking service that lets you log workouts, record biometric measurements, build training routines, and receive performance analytics including your Lift Rating (R-Index) and personalised training recommendations. It also offers community features — shared routines and exercises, leaderboards — and tools for personal trainers to manage clients. Khilo is provided by Khilo Ltd ("we", "us" or "our"), a company registered in England and Wales under company number 17495470. Our registered office is at 66 Paul Street, London, EC2A 4NA, United Kingdom, and you can email us at support@khilo.io. These terms are a contract between you and us. By creating an account or using Khilo you agree to these terms; if you do not agree, please do not use the service. Our Privacy Policy explains how we use your personal data.

Your Account

You must provide accurate information when creating your account and keep your sign-in credentials secure; you are responsible for activity that happens under your account. You must be at least 16 years old to use Khilo. One account per person — accounts may not be shared, sold, or transferred.

Subscriptions & Billing

Khilo is a paid subscription service with Bronze, Silver, and Gold plans, plus a separate Personal Trainer plan. Each subscription is billed by one platform: by Apple through the App Store, by Google through Google Play, or by us directly on the web, where payments are processed by Stripe. A store’s own terms also apply to a subscription bought through it. Plans are billed monthly or annually and renew automatically at the end of each billing period until you cancel. We offer one free trial per person, across the App Store, Google Play and the web. It lasts one month on the App Store and 30 days on Google Play or the web, and Apple and Google also decide whether your Apple ID or Google account is eligible for a trial through their store. Your plan is not charged until the trial ends; it then begins billing automatically unless you cancel first, which on the App Store means at least 24 hours before the trial ends. On the web we take your card details when you subscribe and charge that card automatically: when the trial ends, or at once if you have no trial. The App Store and Google Play instead charge the payment method held by your Apple ID or Google account. On the Personal Trainer plan you also pay for client slots, and the free trial does not cover all of them: a slot you add can be charged when you add it, even during the trial. Through the App Store or Google Play, client slots come as one monthly client-slot bundle at a time: a subscription of its own, with no free trial, that renews separately from the plan. Clients covered by a trainer receive access through their trainer’s subscription; if that cover ends, continued access requires a subscription of their own. A store purchase stays with the Khilo account it was first confirmed on, unless our support team moves it or that account is permanently deleted; after that, a store subscription that is still running can be restored on another account. Apple handles refund requests for App Store purchases under its own policies, and we cannot refund an App Store charge through Apple ourselves; Google Play handles refund requests for Google Play purchases under its own policies. Neither affects your rights as a consumer, which Our Responsibility to You describes. Renewal & Cancellation explains how to cancel, and Referral Programme describes the referral programme.

Renewal & Cancellation

You can cancel at any time. Your access then continues to the end of your billing period and you are not charged again, except that on the App Store a cancellation made in the last 24 hours of a period may not stop the next charge, because Apple charges each renewal during those 24 hours. Cancel with the platform that bills the subscription now: an App Store subscription in your App Store subscription settings (on an iPhone or iPad: Settings › your name › Subscriptions), at least 24 hours before the current billing period ends; a Google Play subscription in your subscription settings in Google Play; and a subscription we bill directly, from Profile › Settings › Subscription on the web. Cancelling a Personal Trainer plan does not cancel a client-slot bundle bought through a store. Cancel an App Store bundle in your App Store subscription settings. We cancel a Google Play bundle for you 30 days after your plan ends, unless you renew the plan first; until then it can renew, so to stop it sooner, cancel it in Google Play. When you join a trainer, a subscription of your own that we bill directly ends at the end of its billing period, but one bought through the App Store or Google Play keeps renewing until you cancel it in that store. Deleting your Khilo account does not cancel an App Store subscription, because Apple does not let us. A Google Play subscription, or one we bill directly, is cancelled when your account is permanently deleted, 30 days after you ask, and can renew before then, so to avoid another charge, cancel any subscription before you delete your account. There is one exception to keeping your access until the end of the billing period: a web subscription you paid for when you subscribed, cancelled within 14 days of subscribing, ends straight away and is refunded in full, as Your Right to Cancel explains. A free trial's 14 days pass during the trial, so they never lead to a refund.

Your Right to Cancel

If you subscribe on the web, the law gives you 14 days to change your mind, from the day you subscribe to the end of the 14th day after it, UK time. What that means for you depends on whether your subscription starts with a free trial. If you pay when you subscribe, for example because you have already had your one free trial, you can cancel within those 14 days and we will refund everything you paid for the subscription. Cancelling from Profile › Settings › Subscription is enough: we then end your subscription straight away, instead of at the end of the billing period, and automatically refund every payment for it to the way you paid; if you are a Personal Trainer, the access you give your clients ends with it. You can also tell us clearly that you want to cancel, by email to support@khilo.io or by post to the address in the Contact section; you do not need to use a form or give a reason, and we will refund you within 14 days of your telling us. If your subscription starts with a free trial, the 14 days fall within the trial, while the plan costs you nothing, so there is no payment for the plan to refund. The first payment, when the trial ends, comes after the 14 days are over: cancelling after it stops your subscription renewing, but that payment is not refunded. To avoid paying, cancel before the trial ends. On the Personal Trainer plan, a client slot you add during the trial can be charged when you add it; if you paid for one within the 14 days, tell us that you want to cancel and we will refund those charges. Subscriptions bought through the App Store or Google Play are refunded by Apple or Google under their own policies, as Subscriptions & Billing explains. These rights are in addition to your other rights as a consumer, which Our Responsibility to You describes.

Referral Programme

You can invite friends to Khilo using your personal referral code or link. A new member can start one free trial, as described in Subscriptions & Billing, and their plan is not charged if they cancel before the trial ends (for an App Store trial, at least 24 hours before it ends). When a friend you referred makes their first successful payment, you each receive free time on your own plan: your friend’s next month is free, so a friend whose monthly plan began with a free trial pays for a single month across their first three (the trial, their first paid month, and the free month), apart from any client slots, and you receive a free month, or two free weeks if your friend’s plan costs less than yours. Rewards are given 14 days after that payment, through the service that bills each of you: on the web, as account credit worth that time, taken off your next invoices; through Google Play, by moving your next payment date back; and through the App Store, as an offer you claim in the Khilo app, which starts at your next renewal. If that payment is refunded within those 14 days, neither reward is given. To earn a reward you must hold an active, paid subscription when it is due. Rewards have no cash value, cannot be transferred, and can be used only against Khilo subscriptions. We may withhold or reverse a reward where we detect abuse — including self-referral, such as signing up a second account with your own payment card — and we may change or end the referral programme at any time.

Community Content & Conduct

You may publish routines and exercises to the community, choose a username and display name that other members see, show sections of your public profile, and appear on leaderboards. You retain ownership of content you create, and grant us a licence to host and display it within Khilo. Everything you publish must follow these rules. It must not be illegal, and in particular it must not threaten, harass or abuse anyone, stir up hatred against people for who they are, promote terrorism or violence, encourage suicide, self-harm or eating disorders, be sexually explicit, exploit or endanger children, infringe anyone's copyright, trade mark or other rights, or be spam, a scam or fraud. It must also not be offensive or misleading, reveal anyone else's personal information, or be dangerous — for example, an exercise likely to cause injury, or a name that impersonates someone. Manipulating leaderboards with false workout data is prohibited, and leaderboard entries may be removed following a moderation review. Khilo has no private messaging between members, and everyone aged 16 and over uses the same moderated community. We remove illegal content as soon as we become aware of it. Violations can result in content removal and strikes against your account; repeated or serious violations can result in a publishing ban or account termination, as the next two sections explain.

Moderation, Strikes & Appeals

We check what members publish before other members see it, using proactive technology: an AI model provided by Anthropic reviews every routine and exercise, and every username and display name, against these rules, so that harmful or illegal content is caught before anyone sees it. The model decides whether the content breaks a rule, how confident it is, and which rule. Content it approves with enough confidence is published; where it is not confident enough to approve, a person on our team reviews the content before it is published. Content it rejects is not published, or is withdrawn if it was already live, and stays in your own library with the reason. When the model is confident that content breaks a content rule, a strike is added to your account automatically, and our team can also issue a strike after reviewing content or a report. A strike expires after 28 days. While you have 3 active strikes you cannot publish, and what you have already published is withdrawn from the community, until enough strikes expire or we lift the restriction. A username or display name the model rejects cannot be used, or is released if it was already in use, and you choose another; a name never leads to a strike. When the creator of a leaderboard asks for an entry to be removed from it, the same model decides whether the reason they give justifies removing it, and a person on our team decides instead when the model would remove the entry but is not confident enough. Because these decisions are made automatically, you can ask for a person to review any of them: use Appeal on a rejected routine in the app, or email us at support@khilo.io about any other decision, including a strike, a restriction or a removed leaderboard entry. A member of our team reviews every appeal and tells you the outcome, and if we agree the decision was wrong we restore your content and remove the strike. Our Privacy Policy explains how moderation uses your personal data.

Reporting, Blocking & Complaints

If you see content or behaviour that breaks these rules, or that you think is illegal, please report it. Use Report on a community routine or exercise, or email us at support@khilo.io for anything else, such as a username, a public profile or a leaderboard entry; tell us what it is and where you saw it. Anyone, including someone without a Khilo account, can report content on Khilo that they believe is illegal by emailing us. To help us act on it, tell us where the content is, why you believe it is illegal, your name and email address, and that you believe in good faith that what you have told us is accurate and complete. When you report by email, we confirm that we have received your report, and then tell you what we decided and how you can challenge that decision. Our team reviews every report and decides whether to remove the content or act against the account that published it, and that member can appeal as the previous section explains. You can also block a creator, from the menu on any routine or exercise they published in Community or from their public profile: you then no longer see what they publish in Community, they are not told, and you can unblock them at any time from your profile. You can complain to us about content you reported, about action we took against your content or account, about how our moderation or its AI works, or about how we meet our duties under the Online Safety Act 2023: email us at support@khilo.io with the word "complaint" and what it concerns. We look into every complaint, tell you what we decided and why, and put things right where we got them wrong, for example by restoring content we removed in error.

Personal Trainer Features

Personal Trainer accounts can invite clients by invite code, cover their access, build routines for them, and record workouts on their behalf. Personal trainers are independent of Khilo — we provide the tools, not the training service itself, and we are not responsible for the advice or programming a trainer gives their clients. Trainers must only use client data within Khilo for the purpose of coaching that client. Demo videos attached to exercises must be published on one of the platforms we accept — YouTube, Instagram or TikTok — by an account the trainer has connected to Khilo, which is how we check that the trainer owns them. Khilo uses YouTube API Services to connect a YouTube account: by connecting one you agree to be bound by the YouTube Terms of Service (https://www.youtube.com/t/terms). A connected Instagram or TikTok account remains subject to that platform's own terms. When a client links to you, you see the training data and body measurements Khilo shares with a trainer, as our Privacy Policy describes. You use that data as an independent controller under data protection law: you are responsible for using it lawfully and only to coach that client, and for keeping it confidential.

Health & Safety Disclaimer

Khilo is not a medical service and does not provide medical advice. Training recommendations — suggested weights, reps, deloads, warm-up sets, and adaptation adjustments — are generated from your logged performance and are for general information only. Consult a doctor before starting or changing an exercise programme, especially if you have a health condition. Weight training carries inherent risk of injury; always train within your limits and use appropriate safety equipment. You use Khilo and act on its recommendations at your own risk.

Intellectual Property

The Khilo app, including the R-Index rating system, analytics, design, and branding, is owned by us and protected by intellectual-property law. “Khilo” is our trade mark and is the subject of a pending UK trade mark application (No. UK00004446017); our logo and other brand elements are not registered trade marks, but remain our property and are protected by copyright and design rights. We give you a personal, non-exclusive, non-transferable licence to use Khilo for your own training while you have an account. These terms do not grant you any right to copy, modify, redistribute, or reverse-engineer the service, except where the law allows it. Content you create remains yours, as described in the Community Content section.

Account Deletion & Termination

You may delete your account at any time using the Delete Account option at the end of this page in the app, or by emailing us at support@khilo.io from the address on your account. Your account is deactivated immediately and scheduled for permanent deletion; you have 30 days to sign back in and cancel the request, after which your account and the personal data we hold about you are permanently removed, except for the limited records described in the Data Retention section of our Privacy Policy. We may suspend or terminate accounts that seriously or repeatedly breach these terms, abuse the service, or create risk for other users. Where we can, we will tell you why and give you a chance to respond first, unless the law, the safety of others or the seriousness of the breach prevents it, and you can ask us to review the decision. Deleting your account does not entitle you to a refund of any unused subscription period except where required by law. Deleting your account does not cancel a subscription bought through the App Store; Renewal & Cancellation explains what happens to each kind of subscription.

Our Responsibility to You

If you are a consumer, the law gives you rights in relation to digital content and services, including under the Consumer Rights Act 2015: we must provide Khilo with reasonable care and skill, and as we describe it. Nothing in these terms affects those rights; Citizens Advice can explain them. Apart from that, Khilo is provided “as is”, and to the extent the law allows we make no other promises about it — for example, that it will always be available or free of errors. We are responsible for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill, but not for loss that was not foreseeable, and not for business losses, because Khilo is for personal use. We are not responsible for injury arising from your own training decisions, as the Health & Safety Disclaimer explains. Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else the law does not allow us to limit or exclude. Otherwise, our total liability to you is limited to the amount you paid for the service in the 12 months before the claim arose, but never below what the law allows, and never so as to stop you recovering the price of a service we did not provide as promised.

If You Got Khilo from the App Store

If you downloaded Khilo from Apple's App Store, these points also apply. These terms are an agreement between you and us, not Apple, and we, not Apple, are solely responsible for Khilo and its content. Your licence to use Khilo is limited to a non-transferable licence to use it on Apple-branded products that you own or control, as the Usage Rules in Apple's Media Services Terms and Conditions permit, except that it may also be used by other accounts associated with you through Family Sharing or volume purchasing where those rules allow. Apple has no obligation at all to provide maintenance or support services for Khilo; that is ours, as these terms describe. If Khilo fails to conform to any warranty that applies to it, you may notify Apple, and Apple will refund the purchase price of the app, if any, to you; to the maximum extent the law permits, Apple has no other warranty obligation with respect to Khilo, and any other claims, losses, liabilities, damages, costs or expenses caused by a failure to conform to a warranty are our responsibility, as these terms set out. We, not Apple, are responsible for addressing any claim by you or a third party relating to Khilo or your possession and use of it, including product liability claims, any claim that Khilo fails to conform to a legal or regulatory requirement, and claims under consumer protection, privacy or similar legislation. If a third party claims that Khilo or your possession and use of it infringes their intellectual property rights, we, not Apple, are solely responsible for investigating, defending, settling and discharging that claim. You confirm that you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties. You must comply with any third-party terms that apply when you use Khilo, such as your mobile data agreement. Apple and Apple's subsidiaries are third-party beneficiaries of these terms, and once you accept them Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary. Questions, complaints and claims about Khilo should be sent to us, at 66 Paul Street, London, EC2A 4NA, United Kingdom or support@khilo.io.

Changes to These Terms

We may change these terms to reflect changes in the law, in how Khilo works, or in the features we offer. Before a change that affects you materially takes effect, we will tell you by email or in the app, at least 30 days in advance unless the law or a security issue requires it sooner, and we will update the “Last updated” date at the top of this page. If you do not agree to the change, you can stop using Khilo and delete your account, and if you have a subscription, you can cancel it before the change takes effect; your access continues to the end of the period you have paid for. Other changes take effect when we publish them here.

Law & Disputes

These terms are governed by the law of England and Wales, and the courts of England and Wales can hear any dispute about them. If you live in Scotland, you can bring legal proceedings in either the Scottish or the English courts, and if you live in Northern Ireland, in either the Northern Irish or the English courts. If you live in the European Union, you keep the protection of the mandatory consumer law of the country where you live, and can bring proceedings in its courts. If something goes wrong, please contact us first, so we can try to put it right.
