Terms of Service
Last updated: February 9, 2026
1. Acceptance of Terms
Welcome to Spellweave. By accessing or using our Magic: The Gathering deck building application and related services (collectively, the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, please do not use our Service.
We reserve the right to modify these Terms at any time. We will notify you of significant changes by posting a notice on our website or sending you an email. Your continued use of the Service after such modifications constitutes your acceptance of the updated Terms.
2. Description of Service
Spellweave provides tools for Magic: The Gathering players to:
- Import and manage card collections
- Build and optimize decks using AI-powered algorithms
- Generate AI-powered deck explanations and strategy guides
- Create AI-generated strategy visualizations
- Export collections and decks in various formats
- Share decks via public links
The Service may include free and paid features. Certain features require a subscription or mana purchase.
3. Account Registration
To use most features of Spellweave, you must create an account. When registering, you agree to:
- Provide accurate and complete information
- Maintain the security of your account credentials
- Notify us immediately of any unauthorized access
- Accept responsibility for all activities under your account
You must be at least 13 years old (or 16 in the European Economic Area) to create an account and use our Service.
4. Beta Access
Spellweave is currently in open beta. During the beta period:
- Features may be incomplete, contain bugs, or change without notice
- We may reset data or make changes that affect your saved content
- The Service is provided "as is" with no guarantees of availability or reliability
By using Spellweave during the beta, you understand and accept these conditions.
5. Subscription Plans and Payments
5.1 Plans
Spellweave offers different subscription tiers with varying features and limits. Plan details, pricing, and entitlements are displayed on our pricing page and may change over time.
5.2 Billing and Auto-Renewal
Paid subscriptions are billed in advance on a recurring basis (monthly or annually, depending on your chosen plan). By subscribing, you authorize us to charge your payment method for the subscription fees plus any applicable taxes. Your subscription will automatically renew at the end of each billing period unless you cancel before the renewal date. It is your responsibility to manage your subscription and cancel if you no longer wish to be charged. You can cancel at any time through your account's billing settings.
5.3 Mana
Certain features (such as AI deck analysis and video generation) may require mana. Mana is non-refundable and has no cash value. Unused mana does not expire unless your account is terminated.
5.4 Cancellation
You may cancel your subscription at any time through your account's billing settings or the subscription management portal. Upon cancellation, you will retain access to paid features until the end of your current billing period. After that period ends, your account will revert to the free tier.
5.5 Refund Policy
All subscription payments and mana purchases are non-refundable. We do not provide refunds or credits for partial billing periods, unused subscription time, or unused mana balances. Because subscriptions renew automatically, you are responsible for canceling before your next renewal date to avoid being charged for the following period. Forgetting to cancel does not entitle you to a refund for any billing period during which you had access to the Service, regardless of whether you actively used it. By subscribing, you acknowledge and agree to this policy.
6. User Content
6.1 Your Content
You retain ownership of any content you create or upload to Spellweave, including collections, decks, and deck names ("User Content").

6.2 AI-Generated Content

AI Output Disclaimer: AI-generated content is provided "as is" without any guarantee of accuracy, completeness, or suitability for any particular purpose.

You are solely responsible for reviewing and verifying AI-generated content before use or distribution.
No Exclusivity: AI-generated outputs are provided to you for personal use. Spellweave does not guarantee exclusivity or uniqueness of generated content.
