Last updated: 2026-09-04. These Terms are an agreement between you and X8 Media LLC, the California company operating the Momentum app and onmomentum.co ("Momentum," "we," "us").
Momentum is a training and coaching app for surfing and related board sports: session logging, conditions data, AI-assisted coaching that is reviewed by expert human coaches, scores, plans, audio memos, and a social feed. During the beta, features may change, break, or be removed at any time.
You must be 18 or older during the beta, provide accurate account information, and keep your account to yourself. We may suspend or terminate accounts that violate these Terms.
Use of Momentum requires accepting the Release of Liability, Assumption of Risk, and Safety Agreement (the "Release"), which is part of these Terms. Coaching content is informational only, is not professional or medical advice, and never assesses whether conditions are safe for you on a given day.
You own the content you post or upload (sessions, videos, photos, comments). You grant us a non-exclusive, worldwide, royalty-free, sublicensable license to host, store, reproduce, display, and adapt that content as needed to operate, improve, and promote the service. You represent that you own or have rights to what you upload and that people appearing in your footage consented to it.
Coaching analysis of your videos is performed by our coaching engine together with expert human coaches who view submitted footage. See the Privacy Policy for how footage is handled.
Model training: we may use the videos you upload to improve Momentum's coaching and analysis models. Accepting these Terms turns that on, and you can turn it off at any time in Settings, under Privacy. From then on your footage is not used that way. Turning it off cannot pull footage back out of a model already trained on it, and it never changes your coaching, your scores, or your streak.
The feed exists to celebrate sessions, not to harm anyone. You may not post or upload content that is illegal, harassing, hateful, sexually explicit, violent, infringing, deceptive, or that targets private individuals. That covers anything you send us, including video you upload for coaching, whether or not it is ever posted. We may remove content and restrict accounts at our discretion. Report and block tools are available on every post in the feed; we review reports and act within one week. Zero tolerance for abusive behavior. Contact: legal@onmomentum.co.
We respond to copyright notices under the DMCA. Send notices to our designated agent: X8 Media LLC, 3101 Ocean Park Blvd Ste 200, #311, Santa Monica, CA 90405, or legal@onmomentum.co. We terminate repeat infringers.
Momentum's software, design, brand, coaching content, scores, and audio (including the coach voice content generated with the coach's consent) belong to us or our licensors. We grant you a personal, non-transferable license to use the app. Don't copy, scrape, resell, or reverse-engineer it.
The beta is free, and beta users receive Pro features at no charge. Paid subscriptions may be introduced later with clear notice and pricing; no charge will ever occur without your explicit action. When subscriptions ship on iOS, they run through Apple In-App Purchase.
Momentum uses service providers (hosting, storage, authentication, voice generation, conditions data — listed in the Privacy Policy) and displays conditions data that may be inaccurate or delayed. Never rely on in-app conditions data for safety decisions.
The service is provided "as is" and "as available," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, and non-infringement. Scores and coaching are opinions, not guarantees of results.
To the fullest extent permitted by law: we are not liable for indirect, incidental, special, consequential, or punitive damages, or lost profits or data; and our total liability for all claims relating to the service is capped at the greater of $100 or the amount you paid us in the twelve months before the claim. Nothing in these Terms limits liability that cannot be limited under California law (including for gross negligence, willful misconduct, or fraud).
We may update these Terms. The current version and the date it took effect are always on this page. If we make a material change we will make reasonable efforts to tell you in the app before it takes effect, and continuing to use Momentum after an update means you accept it. You can stop using the service any time and delete your account (and its data) in Settings. Sections that by nature survive (release, licenses you granted for past content as needed to have operated the service, disclaimers, liability limits, disputes) survive termination.
If a provision is unenforceable it severs. These Terms plus the Release and Privacy Policy are the entire agreement. We may assign these Terms to a successor entity (including the future Momentum company); you may not assign them.
These Terms are between you and Momentum only, not with Apple, and Apple is not responsible for the app or its content.
