Terms of sale and licence

Last updated: 11 November 2026

These terms apply when you buy or use the Master of All Skills Claude Code plugin from Leffler International Investments Pty Ltd (“we”, “us”). By buying or installing it you agree to them.

1. What you buy

• A one-off licence (US$79) to install and use the plugin, with access to updates for 12 months from purchase.
• After 12 months your copy keeps working. Another 12 months of updates is optional (US$39). Neither payment renews automatically.
• Prices are in US dollars. PayPal may convert the amount to your currency and apply its own fees.

2. Licence

• One licence covers one person or one organisation named at purchase, on their own computers and projects, including projects they build for their clients.
• You may not resell, publish, share or redistribute the plugin or its files, or give others access to the private repository.
• We may also grant access free of charge, at our discretion, under the same licence terms.
• We keep all intellectual property rights in the plugin. Code the plugin helps you write in your own projects belongs to you.

3. Delivery

After payment we email the address on your PayPal payment to ask for your GitHub username, then GitHub sends you an invitation to the private plugin repository. Installation steps are in the setup guide on our home page.

4. What you need

Your own Claude plan that includes Claude Code, and a GitHub account. Claude subscription and usage, and any third-party services you connect, are not included and have their own terms and fees.

5. Refunds

Our MOS Plugin Refund Policy forms part of these terms. It includes the voluntary full refund offer within 14 calendar days before download, activation or access, and preserves all applicable mandatory consumer rights. An applicable statutory cancellation does not require a reason or a review. Fault related rights are not limited to that voluntary period. Read the full policy for purchase verification, remedies, original payment processing and licence consequences.

6. Your responsibilities

The plugin proposes and makes changes only with your approval. You are responsible for reviewing changes before merging or deploying them, for backups, and for the accounts, keys and services you connect. Read the disclaimer.

7. Ending access

If you breach these terms, for example by sharing the plugin, we may remove your repository access. For releases 1.4.0 and later, online licence verification is required. A completed refund of the plugin purchase ends that licence and may remove repository access. Expiry of updates alone does not end a paid base licence. Licence checks do not delete your project files. Older locally installed copies cannot be disabled remotely.

8. Liability

To the extent the law allows, our total liability for any claim about the plugin is limited to the amount you paid us for it, and we are not liable for indirect or consequential loss, including lost profits or data. Nothing in these terms limits your rights under the Australian Consumer Law or other laws that cannot be excluded.

9. Changes and law

We may update these terms; the version on this page at the time of your purchase applies to that purchase. These terms are governed by the laws of Australia.
