Terms of Service

Effective: 9 May 2026

These Terms of Service ("Terms") govern your use of the Mantis Crochet Notebook web application at app.mantiscn.com and the related editor at editor.mantiscn.com (together, the "Service"). By creating an account or using the Service you agree to these Terms and to our Privacy Policy.

1. The service

Mantis Crochet Notebook is a tool for crocheters to create, import, organize, calculate, and follow crochet patterns. The Service is currently in pre-alpha. Features may change, break, or disappear on short notice while we iterate.

2. Your account

  • You must be at least 13 years old (16 in the EU) to create an account.
  • You are responsible for keeping your password confidential and for everything that happens under your account.
  • One person, one account. Don't share credentials.

3. Subscriptions and trial

Paid tiers (Maker, Designer, Designer Unlimited) are billed monthly or annually through Stripe. Most paid signups include a 14-day free trial that requires a credit card; if you don't cancel before day 15 the subscription auto-converts to paid. Cancel any time on the billing portal accessible from the settings page; cancellation takes effect at the end of the current billing period.

Pricing and AI feature caps are listed on the public pricing page. We may change prices and caps with at least 30 days' notice; if a change disadvantages you, your existing subscription continues at the prior price until your next renewal.

4. Acceptable use

You agree not to:

  • Reverse-engineer, scrape, or hammer the Service in ways that degrade availability for other users.
  • Use the Service to infringe third-party copyright (for example, by importing and redistributing copyrighted patterns you do not have rights to).
  • Attempt to bypass tier caps, rate limits, payment, or access controls.
  • Use the Service to send spam, harass others, or distribute malicious content.
  • Resell access to your account or its API tokens.

We may suspend or terminate accounts that violate these rules. Severe abuse may be referred to relevant authorities.

5. Your content and your patterns

You keep ownership of every pattern, swatch, photo, and note you create or upload. You grant us a limited license to host, display, and process that content solely so we can operate the Service for you (rendering charts, calculating yardage, sending you email, backing up your data).

Patterns you import from third-party sources remain subject to that source's license. Importing a pattern for personal use is generally fine; redistributing or modifying for commercial use may require the original designer's permission. You are responsible for respecting third-party terms.

6. AI features

Pattern import, chart generation, and similar AI features pass your input through third-party LLM providers (OpenAI, Anthropic). These providers process your input under their own terms. We do not use your content to train models. AI output is best-effort and may be wrong; you are responsible for reviewing it before relying on it for a finished project.

7. Service availability

We aim for high availability but make no uptime guarantee at this stage. We may add, remove, or change features. We may take the Service offline for maintenance with as much notice as is reasonable.

8. Termination

You can delete your account at any time on the account page. We may terminate accounts that violate these Terms, fail to pay, or are inactive for an extended period. Termination cancels any pending subscription and removes your data per our Privacy Policy.

9. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Service will be error-free or uninterrupted, or that any pattern import or AI feature will produce accurate output.

10. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS PRECEDING THE CLAIM AND (B) USD $50. IN NO EVENT WILL WE BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES.

11. Changes to these terms

Material changes will be emailed to the address on your account at least 7 days before they take effect. Continued use of the Service after a change means you accept the updated Terms. The effective date at the top of this page reflects the most recent version.

12. Governing law

These Terms are governed by the laws of the State of Arizona, USA, excluding its conflict-of-laws rules. Disputes will be brought in the state or federal courts located in Maricopa County, Arizona.
