Terms of use

Theoretical Enterprises, LLC provides music-theory, practice, document and performance tools. They are educational aids, not a promise that every generated fingering will suit every player, instrument or performance. You are responsible for checking tuning, charts, transposition, cues and backups before relying on them.

You must provide an email address you control, protect access to your email and browser session, and promptly revoke a device you no longer use. Do not share verification codes or session credentials. You remain responsible for activity authorized through your account until you report or revoke that access.

Account holders and purchasers must be at least 18 years old or the age of legal majority where they live. Requesting a sign-in code requires an adult attestation and acceptance of the current Terms and Privacy policy. A teacher may give an assignment link only to a student who is at least 13 and has any authorization required from the student's parent, guardian or responsible school, and must use a nickname or initials rather than identifying or sensitive information.

Barre None does not create student accounts. Children under 13 may not create an account, purchase Pro, retrieve a cloud assignment or submit assignment work online. They may use the local browser tools with a parent, guardian or teacher. Previously saved local work can be exported and handled by that adult without sending it to Barre None.

You keep ownership of charts, notes, recordings and other material you provide. You grant Barre None a limited permission to store, copy, process and transmit that material only as needed to provide the features you choose, such as sync, backup, a workspace, an event, an assignment or a private asset download. This permission ends when the material is deleted from the service, subject to active shared copies, bounded recovery periods and legal recordkeeping.

You must have the rights and permissions needed for anything you upload or share. Do not use the service to distribute unauthorized lyrics, tablature, recordings or other protected material. Workspace members and link recipients may keep copies they already downloaded; removing access cannot erase those copies.

Do not use Barre None to break the law, infringe rights, harass or impersonate someone, distribute malware, probe or bypass access controls, interfere with the service, scrape private content, automate abusive traffic, or send unsolicited invitations. Do not try to derive another person's account, invitation, assignment, asset or workspace token.

Barre None may restrict or terminate cloud access when reasonably necessary to protect users or the service, respond to legal process, address infringement, or stop a material breach. A repeat-infringer policy applies to account holders who repeatedly upload or share infringing material. Where practical, you will receive notice and an opportunity to export your own content unless immediate action is required.

Public purchasing is currently closed. If opened, Pro will be offered as the same feature package at $1.99/month or $19.99/year. A paid subscription renews at its selected interval until canceled. Price, interval, renewal, included features and any taxes are shown before payment. Lemon Squeezy processes the transaction as merchant of record and may present additional checkout terms.

You can cancel through the customer billing portal. Cancellation stops future renewals and keeps Pro active through the paid period unless a refund or provider action ends it earlier. After paid access ends, cloud data becomes read-only and is scheduled for deletion 90 days after the paid access end. Local work remains on your device. Export it before the retention deadline.

Failed payments may receive a seven-day access grace period. A verified service outage may preserve already-active access for up to 30 days. These safeguards do not extend a canceled paid period or create additional paid time.

The browser tools are provided as available. Cloud, email, microphone, MIDI, wake lock, installation and payment features depend on browsers and third-party services. Barre None may change or discontinue a feature, but will not knowingly shorten a paid period without providing a remedy required by law. Material changes to these terms will be posted here with a new effective date and, where required, additional notice.

To the extent the law permits, the service is provided without implied warranties of merchantability, fitness for a particular purpose or uninterrupted operation. Nothing in these terms excludes a warranty or consumer right that cannot lawfully be excluded.

To the extent permitted by law, Barre None is not liable for indirect, incidental, special or consequential loss, lost performance income, lost data or unavailable service. For claims relating to paid service, aggregate liability is limited to the amount you paid for Barre None during the 12 months before the event giving rise to the claim. These limits do not apply where liability cannot legally be limited.

The laws and courts that must apply under consumer, privacy and other mandatory rules continue to apply. These terms do not require arbitration or waive a right to bring a claim in a court or consumer forum that has jurisdiction.
