Terms of Service
Last updated 8 September 2026
1. What this service is
Violinista is a practice tool for string players. It shows MIDI and MusicXML files on a fingerboard, tunes an instrument, and scores scale intonation through your microphone. It is not a substitute for instruction from a qualified teacher.
2. Accounts
The free tier works without an account. You can use a supported social provider or create an account with a verified email and password. Social account passwords do not reach us. First-party passwords are stored as salted one-way hashes. You are responsible for activity under your account. Contact us to delete it.
3. Plans and payment
The Free plan is free indefinitely and is not a trial. Premium costs $7 per month or $60 per year, billed through Stripe. We do not receive or store your card details. Premium begins with a 14-day free trial. Stripe collects your card when you subscribe and charges it when the trial ends. Subscriptions renew automatically until cancelled.
4. Cancelling and refunds
You can cancel from the billing page. Access continues to the end of the paid period. We do not automatically refund partial periods. Contact us about an unexpected charge or service problem. This does not affect any refund rights required by law.
5. What happens to your practice data
You can export every session and scored note as CSV or JSON on any plan. Cancelling does not delete your history. The most recent seven days remain visible on the Free plan. You can still open, download and remove your existing private uploads and submissions after Premium ends.
6. Acceptable use
Do not attempt to break, overload or gain unauthorised access to the service, and do not upload material you do not have the right to use. Automated scraping or resale of the service is not permitted. This does not restrict the permissions granted by a public score’s stated license.
Public score library
Browsing and practising approved public scores is free. Saving a custom score privately or submitting it for public review requires Premium. A submission is not public until approved. You must have permission to share the exact score and arrangement under its selected license, with the required credits. Reviews check compatibility, musical suitability and stated rights; they do not guarantee that a score is error-free. Use the report control or contact support about errors or rights concerns. Uploads may be rejected or withdrawn. Removing a publication here cannot recall copies already downloaded or revoke rights already granted by its license.
7. Availability
We do not guarantee uptime. Features may change. We will give notice of significant changes when possible.
8. Liability
The service is provided as it is. To the extent permitted by law, our total liability to you for any claim relating to the service is limited to the amount you paid us in the twelve months before the claim. Nothing here limits liability for death, personal injury, or fraud, or any other liability that cannot lawfully be limited.
9. Contact
For questions about these terms, billing, or your account, email [email protected].
10. Changes and governing law
We may update these terms; the date at the top will change and material changes will be announced in the app. Continued use after a change means you accept the updated terms. These terms are governed by the laws of the jurisdiction in which the operator of Violinista is established.
