Terms of service
Last updated November 9, 2026. These terms are between you and mcstech, llc ("we").
The service
Castagent lets Shopify merchants create, schedule and publish social media posts, generate captions and images with AI, and measure results. You're responsible for what you publish and for following each social network's rules.
AI content
AI output can be wrong. Review captions and images before publishing; the claims check helps but isn't legal advice. You own the content you create with Castagent, to the extent the law allows.
Billing and credits
Paid plans and credit packs are billed through Shopify. Plan credits refill every 30 days and don't roll over. Purchased credits expire 12 months after purchase. Credits for AI generations that fail on our side are refunded automatically. Posting to X uses credits because X charges per post.
Availability
Social networks can change or limit their APIs at any time. We'll do our best to keep publishing working and to tell you when a network changes, but we can't guarantee any network's availability.
Liability
To the extent the law allows, the service is provided as is, and our total liability is limited to what you paid us in the 3 months before the claim.
