The agreement between Illumenza and coaches who use Illumenza Coach.
These terms govern your use of Illumenza Coach ("the Service"), operated by YAP FENG YUAN, trading as Illumenza ("we", "us"), a sole proprietorship in Japan. By creating an account you accept them.
They bind coaches. Your clients are not party to this agreement — their relationship is with you, governed by your own terms and the coaching agreement they sign.
Illumenza Coach is software for running a coaching practice: enrolment links, electronic agreements, payment collection, scheduling and session booking, client records, and the public pages you publish. We provide the tools. We do not provide coaching, and we are not a party to any agreement between you and a client.
You decide what client data you collect and why, so you are the controller of it. You are responsible for:
Paid plans renew automatically each month until cancelled. Cancel any time in the billing portal; Pro stays active until the end of the period you already paid for. Fees are non-refundable except where the law requires otherwise. We may change prices with at least 30 days' notice by email; the new price applies from your next renewal.
Payments your clients make to you flow through your own connected payment account. We are not the merchant of record for those transactions, do not hold those funds, and take no cut of them.
Don't use the Service to:
Everything you upload — page content, agreements, notes, branding — stays yours. You grant us only the licence needed to host, process, and display it in order to run the Service for you. You keep responsibility for having the rights to it.
The Service itself, its code, and its branding remain ours. These terms grant you a limited, non-exclusive, non-transferable right to use it while your account is in good standing.
The Service integrates Stripe, Google Calendar, Documenso, and email delivery providers. Your use of those is also subject to their own terms, and outages or changes on their side can affect features here. We are not responsible for their acts or omissions.
We aim to keep the Service running and to give notice before planned maintenance, but we offer no uptime guarantee. Features may be added, changed, or removed; we'll tell you before removing anything you materially depend on.
The Service is provided "as is", without warranties of any kind to the fullest extent the law allows. We are not liable for indirect, incidental, or consequential damages, for lost profits, or for lost data. Where liability cannot be excluded, our total liability for any claim is capped at the fees you paid us in the twelve months before the claim arose. Nothing here limits liability that cannot lawfully be limited — including liability to consumers under Japanese law.
You may close your account at any time. We may suspend or terminate an account that breaches these terms, doesn't pay, or puts the Service or other users at risk — with notice where circumstances allow. On termination you can export your data during a 30-day window, after which it is deleted as described in the Privacy Policy.
We may update these terms. Material changes will be emailed to coaches at least 30 days before they take effect; continuing to use the Service after that means you accept them.
These terms are governed by the laws of Japan. Any dispute arising from them is submitted to the district court having jurisdiction over our principal place of business as the exclusive court of first instance — without prejudice to any right a consumer has under Japanese law to bring proceedings in their own local court.
