Terms of service

Last updated November 08 2026

These terms are an agreement between you and GM Companion (“we”, “us”) about the GM Companion desktop app and this website. By creating an account or using the app, you accept them. If you don't agree, please don't use GM Companion.

1. Your account

You need an account to use the app. You sign in with Google, Discord or a code sent to your email address. Keep access to that email or account secure: whoever can sign in with it can use your subscription. You must be old enough to enter into this agreement where you live, or have a parent or guardian's permission.

2. Free trial

The first time an account subscribes, it gets a 7-day free trial. Checkout asks for a payment method, but nothing is charged during the trial. Unless you cancel before the trial ends, the subscription starts and the first payment is charged when the trial ends. One free trial per person and per account.

3. Subscription and payment

• The subscription renews automatically at the end of each period (monthly or yearly) and is charged at the start of each new period, until you cancel.
• Purchases are processed by Stripe and sold through Link, which is the seller of record for your payment. Link collects any applicable sales tax and sends your receipts. Link's terms also apply to the purchase.
• The price, in your currency and with tax, is shown at checkout before you pay. Current prices are on the pricing page.
• If we change the price, we'll tell you by email at least 30 days before it applies to you. The new price applies from your next renewal after that, and you can cancel before then.
• If a payment fails, Stripe tries again over the following days and the app keeps working while it does. If payment can't be collected, the subscription ends.

4. Cancelling and refunds

You can cancel at any time in the app, under Options, Account, Manage subscription, or from your Link account. Cancelling stops future renewals. You keep access until the end of the period you've already paid for, and there's no charge for cancelling.

Payments already made aren't refunded for partly used periods, except where the law says otherwise. If something went wrong, such as a charge you didn't expect, write to support@gm-companion.com and we'll sort it out. You can also ask Link's support for help with a payment.

5. Your licence to use the app

While your subscription is active, we give you a personal, non-exclusive, non-transferable licence to install and use GM Companion on computers you use, for your own games, including games you run for others. The app stays our property; you get the right to use it, not ownership of it.

You agree not to:

• get around, disable or interfere with the subscription check or any other protection in the app;
• share your account, or sell, rent or redistribute the app;
• copy, modify or reverse-engineer the app, except as far as the law allows despite this restriction;
• use the app in a way that breaks the law or the rights of others.

6. Your content

Everything you create or bring into the app, like your campaigns, notes, pictures, maps and recordings, belongs to you (or to whoever you got it from). It's saved on your computer, and we don't receive it or claim any rights over it. You're responsible for having the right to use what you import, and for keeping backups. If you record a session, make sure everyone at the table knows and agrees.

7. AI features

AI features are optional and use a provider you choose: a cloud service with your own account and key, or a model on your own computer. Your use of a provider is governed by its own terms, and any costs it charges are between you and it. AI can be wrong: check what it writes before relying on it, especially imported rules and statistics.

8. Game content and trademarks

GM Companion is independent software and isn't affiliated with, endorsed or sponsored by Wizards of the Coast. Dungeons & Dragons and D&D are trademarks of Wizards of the Coast LLC.

The app includes material from the System Reference Document 5.2 (“SRD 5.2”) by Wizards of the Coast LLC, available at dndbeyond.com/srd. The SRD 5.2 is licensed under the Creative Commons Attribution 4.0 International License.

9. Updates and availability

We improve the app over time, and installed copies update themselves. We may add, change or remove features, but we won't remove a major feature you're paying for without telling you first. The app needs an internet connection to sign in and to check your subscription; after a successful check it keeps working offline for 14 days. We work to keep our services running, but we can't promise they'll never be interrupted.

10. Warranty and liability

We provide GM Companion as it is and as available. To the extent the law allows, we don't make promises beyond those in these terms, and we aren't liable for indirect losses or for losing data stored on your computer. Our total liability for any claim is limited to what you paid us in the 12 months before it arose.

Nothing in these terms limits rights that consumer protection law gives you and that can't be waived, including under Quebec's Consumer Protection Act if you live in Quebec.

11. Ending this agreement

You can stop using GM Companion and cancel at any time, and you can ask us to delete your account. We may suspend or close an account that seriously breaks these terms, for example by getting around the subscription; where it's reasonable, we'll warn you first and give you a chance to fix it. Your campaigns remain on your computer either way.

12. Changes to these terms

If we change these terms, we'll update the date at the top. For significant changes, we'll tell you by email or in the app at least 30 days before they take effect, and you can cancel before then if you don't agree.

13. Law and disputes

These terms are governed by the laws of Quebec, Canada, without taking away the protection of the consumer laws where you live. If there's a problem, please write to us first; most things can be solved quickly.
