By creating an account or using Ægir Iron (the "App"), you agree to these Terms of Service. If you do not agree, do not use the App.
Ægir Labs, LLC provides strength training tracking and coaching software. The App allows athletes to log training sessions, track personal records, and connect with coaches. Coaches may use the App to program training, monitor athlete progress, and deliver meet plans.
Account creation: You must provide accurate information when creating an account. You are responsible for maintaining the security of your password.
Athlete accounts: Athletes may only join a coach's roster via a personal invite link provided by their coach. By joining via invite link you consent to your coach having access to your training data.
Coach accounts: Coaches are responsible for the accuracy of programming they deliver to athletes through the App.
You agree not to:
Certain features of the App require a paid subscription. By subscribing you agree to pay the applicable fees. On the web, payments are processed by Stripe, Inc. On iOS, subscriptions are sold and processed by Apple through the App Store (with subscription state tracked via RevenueCat), and are subject to Apple's terms, including auto-renewal and Apple's own cancellation and refund policies. Except where required by law, or where an Apple purchase is refunded under Apple's policies, subscription fees are non-refundable.
We reserve the right to change pricing with 30 days notice to existing subscribers.
Ægir Assistant Coach (AI add-on): The in-app AI assistant is a separate, optional subscription that is additive to your base plan and is not bundled into coaching. It is off until you enable it, has no free trial, and is subject to a monthly usage limit. You can cancel it at any time through the same channel you purchased it (Apple on iOS, or our card checkout on the web); turning off the in-app toggle hides the feature but does not by itself cancel the subscription.
Your use of the App is also governed by our Privacy Policy, which is incorporated into these Terms by reference.
You retain ownership of your training data. By using the App you grant Ægir Labs, LLC a limited license to store and process your data solely for the purpose of providing the service.
Optional third-party integrations: The App lets you optionally connect third-party services, such as Strava, and share your workout data to them at your direction. These connections are off until you enable them. When you share data to a third-party service, your use of that service and the data you send to it are governed by that service's own terms and privacy policy, not these Terms.
AI assistant (Ægir Assistant Coach): This feature is off until you enable it. When you enable it and send a message, the text you type plus the training context needed to answer it (such as your recent logs, training maxes, analytics summaries, and the exercise catalog) is sent to Anthropic, PBC, a third-party AI provider, to generate the response. Your inputs are not used to train Anthropic's models. Your use of this feature is additionally subject to Anthropic's applicable terms. If you do not want your content sent to this provider, leave the feature disabled, which is the default.
The App is a tool for tracking athletic training data and provides pre-built program templates for informational and educational purposes only. These templates are general in nature and are not personalized to your fitness level, health conditions, or physical limitations. Ægir Labs, LLC is not a medical provider, licensed trainer, or healthcare professional. Nothing in the App constitutes medical advice, diagnosis, or treatment. Consult a qualified healthcare provider before beginning any exercise program. You assume all risk associated with your training activities.
Any output from the in-app AI assistant, including suggestions, analysis, and generated programs, is produced automatically, is informational and educational only, and is not personalized medical advice. It may be inaccurate or incomplete, so review it before acting, and confirm any change before it is saved.
The App, including all software, design, and content created by Ægir Labs, LLC, are protected by copyright and other intellectual property laws. You may not copy, modify, or distribute any part of the App without our written permission.
We reserve the right to suspend or terminate your account at our discretion if you violate these Terms. You may delete your account at any time by contacting angela@aegirlab.com.
THE APP IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, ÆGIR LABS, LLC SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING FROM YOUR USE OF THE APP.
These Terms are governed by the laws of the State of Oregon, without regard to conflict of law principles. Any disputes shall be resolved in the courts of Oregon.
We may update these Terms from time to time. Continued use of the App after changes constitutes acceptance of the updated Terms. We will notify users of material changes via email.
