Cantus is a client, calendar, invoicing, and business-management tool for piano technicians, provided by Moore Piano Services / Petra Moore LLC ("we," "us"). By creating an account, you agree to these terms.
During the private beta period, Cantus is provided at a discounted founder rate. The service may change, improve, or experience temporary interruptions as we develop it. Beta participants agree to report bugs and provide feedback in good faith. Your founder-rate pricing, once set, is locked for the life of your account as long as your subscription remains active.
You must provide accurate information when signing up. You are responsible for keeping your login credentials secure and for all activity under your account. One account is intended for one technician or one business. Cantus is currently invite-only; accounts are created at our discretion.
Cantus is built for piano technicians running a piano service business, not as a benchmark for other software makers. Registration is not open to any individual who is an employee, contractor, owner, or affiliate of a business that develops, sells, or operates competing piano-technician or field-service management software, including but not limited to Gazelle.
Registering an account for the purpose of market research, competitive analysis, feature mapping, or design replication — regardless of whether you also happen to be a piano technician — is a material breach of these terms and grounds for immediate termination without notice or refund.
You own the data you enter into Cantus. We do not claim any intellectual property rights to your client lists, business information, invoices, photos, recordings, or files. You are responsible for the accuracy of the data you enter and for complying with applicable law regarding the personal information of your own clients. See our Privacy Policy for details on how data is stored and protected.
When you enable reminder, follow-up, or review-request features, Cantus sends messages to your clients on your behalf using your business name and contact information. You are responsible for ensuring you have an appropriate relationship with the recipients and that the messages comply with applicable laws (including CAN-SPAM for email and, when text messaging becomes available, TCPA). You can disable automated sending at any time through Settings.
Cantus allows you to generate private, shareable links that show your clients limited, read-only information about their own piano(s). You are responsible for sharing these links only with the intended client. We do not control who you share links with, and we are not liable for data exposure resulting from a link being shared with unintended recipients.
Cantus is designed exclusively for managing a legitimate piano service business. You agree not to:
We reserve the right to suspend or terminate accounts that violate these terms, with notice where practical and without refund for the current billing period.
Cantus — including its name, logo, design, user interface, visual identity, source code, documentation, and all related materials — is the intellectual property of Moore Piano Services / Petra Moore LLC. All rights are reserved.
Trademarks. "Cantus" is a trademark of Petra Moore LLC, the subject of a pending U.S. federal trademark application (Serial No. 50007476). The Cantus name and logo may not be used in connection with any product or service that is not provided by us, or in any manner likely to cause confusion about the source of a product or service. Nothing in these terms grants you any right to use the Cantus name or logo except as described below.
Your own data (client records, business information, photos, invoices) remains your property at all times — this section applies only to the Cantus product itself, not to the data you store in it.
Subscriptions bill automatically on a recurring monthly basis via Stripe. You can cancel at any time; cancellation takes effect at the end of the current billing period, and you retain full access until then. No refunds are issued for partial billing periods unless required by applicable law. Prices may change for new subscribers, but your rate is locked as long as your subscription remains continuously active.
Cantus facilitates online invoice payments between you and your clients through Stripe, including through Stripe Connect, which lets payments go directly into your own connected Stripe account. We are not a party to the transaction between you and your client. You are responsible for the accuracy of invoices you issue, applicable sales tax, and any disputes with your clients regarding payments.
We aim for high availability but do not guarantee uninterrupted service. Planned maintenance will be communicated in advance when possible. Support is provided on a best-effort basis via support@getcantus.com.
Cantus relies on third-party services — including Stripe for payments, Supabase for data storage, Netlify for hosting, and Resend for email delivery. We are not liable for financial losses, missed appointments, delayed reminders, or failed transactions caused by an outage, error, or interruption in any of these third-party services, whether or not it also affects Cantus.
You may export a complete copy of your data at any time using the built-in backup feature. You may delete your account directly from Settings at any time; this is a self-service, irreversible action. If you cancel your subscription without deleting your account outright, your data is retained for 30 days and then permanently deleted. You may also request deletion by contacting support.
You may close your account at any time, either directly through Settings or by contacting support. We may suspend or terminate accounts that violate these terms, with notice where practical. Upon termination, the data retention and deletion policy in section 13 applies.
Cantus is provided "as is" and "as available." To the fullest extent permitted by law, Moore Piano Services / Petra Moore LLC is not liable for indirect, incidental, special, consequential, or punitive damages arising from your use of the service, including but not limited to loss of data, loss of revenue, or business interruption. This includes financial losses, missed appointments, or transaction failures caused by outages or errors in Stripe or other third-party integrations we rely on, as described in section 12. Our total liability to you for any claim arising from the service is limited to the amount you have paid us in subscription fees during the 12 months preceding the claim.
You agree to indemnify and hold harmless Moore Piano Services / Petra Moore LLC from any claims, damages, or expenses arising from your use of the service, your violation of these terms, or your violation of any law or the rights of a third party.
These terms are governed by the laws of the State of South Carolina. Any disputes will be resolved in the courts of Greenwood County, South Carolina.
We will notify active subscribers by email before material changes to these terms take effect. Continued use of the service after notification constitutes acceptance of the updated terms.
