Calamus Terms of Service

Last updated: November 2026

These Terms are an agreement between you and BrandCast Labs LLC (“we”, “us”), 127 West Hargett Street, Suite 301, Raleigh, NC 27601. They cover the Calamus apps for macOS, Windows and Android, calamus.cc, my.calamus.cc and the Calamus Pro service. When you use Calamus or start a trial, you accept these Terms and our Privacy Policy.

Who can use Calamus

You must be 13 or older. If you are under 18, a parent or guardian must agree to these Terms for you. We offer Calamus in the United States.

Your license key

Your license key is your login. There is no password. Anyone who has your key can use your account, so keep it private.

If you lose your key, use Email me my key on my.calamus.cc. We send the same key to the email address on the account. We cannot send it to a different address.

Plans

• Free runs on macOS and Windows. You can change one story. Your other stories are read-only. Reed works with an AI provider that you set up and pay for yourself.
• Pro is a monthly or annual subscription. You can change every story, Reed uses AI credits through Calamus, you can sync your stories between devices, and you can use the Android companion app.
• Complimentary licenses are Pro licenses that we give at our choice. They have no billing.

Billing

Stripe processes all payments. We do not sell anything inside the apps. Prices show at Stripe Checkout before you pay. Taxes are added where the law requires them.

• Trial. Pro starts with a 14-day trial. A card is necessary to start it. If you cancel before the trial ends, we charge you nothing. Stripe sends you a reminder email 7 days before the trial ends. If you do not cancel, the subscription starts and your card is charged when the trial ends.
• Renewal. The subscription renews each month or each year, and your card is charged each time, until you cancel.
• Cancellation. Cancel at any time on my.calamus.cc with Manage billing. Pro continues until the end of the period you paid for. Then it stops, and we do not charge you again.
• Plan changes. You can change between monthly and annual in Manage billing. The change is prorated. If the new plan costs more, you pay the difference. If it costs less, the difference becomes a credit on your account for later invoices. It is not paid back to your card.
• AI credits. Each paid period of Pro, and the trial, includes AI credits. You can buy more credits on my.calamus.cc. A Reed request uses credits based on what the AI service charges for that request. Credits do not expire. They stay on your account when Pro ends, but you can use them only during a trial or an active Pro subscription.
• Refunds. We do not give refunds for subscription periods, partial periods, plan changes or credits, except where the law requires it. If you think we charged you in error, write to support@calamus.cc. We can give a refund at our discretion.
• Failed payments. If Stripe cannot collect a payment, Pro stops.
• Price changes. Before a new price applies to your subscription, we tell you by email. You can cancel before the new price starts.

When Pro ends

Your stories stay on your device. On macOS and Windows, the Free plan applies: you can change one story, and the others are read-only. The companion apps stop working until Pro is active again. Synced copies on our servers are deleted 30 days after Pro ends.

Your stories

You own your stories. You also own what Reed writes for you, to the extent that the law lets anyone own it. We get no rights to your stories, except the rights we need to run Calamus for you: to send the parts of a story that Reed needs to the AI service, and to store synced copies when you use sync. We do not use your stories to train AI models.

Reed and AI

Reed uses AI models that other companies run. On a trial or Pro, requests go through Calamus to OpenRouter, and only to model hosts that do not keep the text. On Free, requests go to the provider that you set up, under that provider’s terms.

AI output can be wrong. It can also be similar to existing work. You are responsible for what you publish. If a Reed reply is offensive or harmful, use Report on that reply in the app. We can change the AI models and services that Reed uses.

Acceptable use

Do not use Calamus to:

• break the law or the rights of other people;
• make content that the AI model providers’ policies prohibit;
• share your license key publicly, or resell access or credits;
• attack, overload, reverse engineer or get around the limits of the Calamus servers.

We can suspend or close an account that breaks these rules or that does not pay.

Sync

Sync is a Pro feature. Your device holds the main copy of your stories. Sync stores a copy on our servers so that your other devices can get it. We keep recent versions, but sync is not a guaranteed backup. Keep your own backups. The Privacy Policy says what sync stores and for how long.

Deleting your account

You can delete your account on my.calamus.cc. This cancels your subscription at once, with no refund. It deletes your synced stories, your license record and your billing record at Stripe, and your key stops working. Stripe keeps the payment records that the law requires.

Disclaimers

Calamus is provided “as is” and “as available”. To the extent the law allows, we make no warranties, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We do not promise that Calamus will always be available, free of errors, or that it will never lose data.

Limitation of liability

To the extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost data, profits or revenue. Our total liability for any claim about Calamus is limited to the amount you paid us in the 12 months before the claim, or $50 if you paid nothing.

Changes to these Terms

We can change these Terms. We post the new version on this page and change the date at the top. If a change is important, we tell Pro subscribers by email before it applies. If you continue to use Calamus after a change, you accept the new Terms.

Law

The laws of North Carolina govern these Terms. Any dispute goes to the state or federal courts in Wake County, North Carolina.
