Privacy Policy

This policy explains how Violin Tab App collects, uses, shares, retains, and deletes information when you use the website, app, memberships, email-interest form, and microphone tutor.

• Account and authentication. Clerk processes sign-up, sign-in, session, email address, and optional profile information. Violin Tab App stores the Clerk user identifier needed to connect your account to product data. We do not receive your password.
• Membership and billing. Stripe processes payment details. We store a Stripe customer reference and use subscription status, plan, renewal, and cancellation information to provide paid access. We do not store full card numbers.
• Email interest. If you submit the marketing interest form, we store the normalized email address and submission dates for Violin Tab App updates.
• Browser-saved preferences. Favorites and some practice preferences and summary progress metrics may be stored on your device using browser storage. These values do not include microphone audio or raw pitch samples. Clearing browser data removes those local values.
• Microphone tutor. Microphone access requires your device permission. Pitch analysis happens live on your device. Violin Tab App does not record, upload, transmit, or store the microphone audio used by tutor mode, and raw pitch samples are not retained after live analysis.

We use information to authenticate learners, deliver free and paid features, process and support memberships, respond to support and deletion requests, send requested updates, analyze pitch on the device without retaining microphone audio, protect the service, and meet legal obligations.

We use Clerk for authentication, Stripe for billing, Replit for application hosting, and related technical providers needed to operate the service. These providers process information under their own service terms and privacy commitments.

We do not sell personal information. We may disclose information when required by law, to protect users or the service, or as part of a business transfer subject to appropriate safeguards.

• Microphone tutor audio is analyzed in real time on the learner’s device. It is not recorded, uploaded, or stored by Violin Tab App, and raw pitch samples are not retained after live analysis.
• Violin Tab App no longer accepts learner performance recording submissions.
• If a legacy submission from the former recording program is still associated with an account, the learner may request its removal or delete the account. Legacy recording objects are placed on the deletion queue, and temporary storage or network failures are retried until cleanup completes.

A signed-in learner can open Account, choose Delete account, review the consequences, and confirm by typing DELETE. Completion cancels active Violin Tab App subscriptions, retires the Stripe customer used by this product, deletes the Clerk identity and local account mapping, removes matching email-interest entries, and removes any legacy submission records or recording objects associated with the account.

Account deletion is permanent and does not itself promise a refund. Stripe and other providers may retain transaction or security records where required by law. If you cannot sign in, use the public support and deletion instructions.

A parent or guardian should supervise a child’s use of Violin Tab App and manage the child’s account, billing, and device permissions as appropriate. Tutor mode does not record, upload, or store microphone audio. A guardian who believes a child provided account or email-interest information without appropriate permission should contact support so it can be reviewed and deleted.

You can deny or revoke microphone permission, manage billing through Stripe, request removal of email-interest information, and delete your account. We use reasonable technical and organizational protections, but no online service can guarantee absolute security.

We may update this policy as the product or law changes. The effective date above identifies the current version. Material changes will be presented through an appropriate public or in-product notice.

Privacy, access, correction, email removal, and deletion questions can be sent to classicalviolintab@gmail.com. Do not send passwords, payment-card details, or recording files by email.
