Effective Date: February 9, 2026
These Terms of Service ("Terms") govern your access to and use of the Foyl application and related services (the "Service") operated by Triluna Industries ("we," "us," "our"). By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.
You must be at least 16 years of age to use the Service. By creating an account, you represent that you are at least 16 years old and have the legal capacity to enter into these Terms. If you are using the Service on behalf of an organization, you represent that you have the authority to bind that organization to these Terms.
Foyl is an AI-powered dialectic reasoning tool that challenges your ideas through structured argumentation. The Service uses large language models (primarily Anthropic's Claude) to generate responses that test, question, and refine your thinking.
Important: AI-generated content is produced by machine learning models and may contain errors, inaccuracies, or biases. The Service does not provide professional, legal, financial, medical, or any other expert advice. You should not rely on AI-generated content as a substitute for professional judgment.
The Free tier includes limited access to the Service, including up to 3 streams per month, 3 forges per month, markdown export, and a maximum intensity of 5. No credit card is required.
The Plus tier provides expanded access including unlimited streams and forges, all export formats, the full intensity range, concept graphs, cross-stream synthesis, and additional features. Plus requires a paid subscription.
We reserve the right to modify pricing at any time. Changes to subscription pricing will take effect at the start of your next billing cycle. We will provide at least 30 days' notice of price increases via email.
Plus subscriptions are billed monthly or annually through Stripe. By subscribing, you authorize us to charge your payment method on a recurring basis until you cancel.
New Plus subscribers may receive a 14-day free trial. You will not be charged during the trial period. If you do not cancel before the trial ends, your subscription will automatically convert to a paid plan.
You may cancel your subscription at any time through the Stripe customer portal or by contacting us at support@foyl.dev. Upon cancellation:

These Terms, together with the Privacy Policy, constitute the entire agreement between you and Triluna Industries regarding the Service.
If any provision of these Terms is held to be unenforceable, the remaining provisions remain in full force and effect.
Our failure to enforce any provision of these Terms does not constitute a waiver of that provision or any other provision.
You may not assign your rights under these Terms without our prior written consent. We may assign our rights and obligations without restriction.
We reserve the right to modify these Terms at any time. We will notify you of material changes by posting the updated Terms on this page and updating the effective date.
