Terms of Service
These Terms govern your use of Chopinly — the web app and installable app at chopinly.com and the account service behind it (the "Service"), operated by LaLa Solutions LLC, a Delaware limited liability company ("we", "us"). By using the Service you agree to these Terms and to the Privacy Policy. If you do not agree, please don't use the Service.
1. What Chopinly is
Chopinly is a practice assistant for musicians: a practice clock attributed to goals, notes, a history and analytics, plus a metronome, tuner, pitch pipe, sight-singing books and a reader for your own sheet music. It runs in your browser and works without an account. An optional account backs your practice up and syncs it between your devices, and gives you a private space for the score files you choose to upload.
2. Who may use it
Anyone may use the app without an account. To create an account you must be at least 16 years old, or have a parent's or guardian's permission, and be able to enter into this agreement. If you use Chopinly on behalf of a school or organization, you confirm you are allowed to accept these Terms for it.
3. Your account
You sign in with a one-time code sent to your email address; there is no password. You are responsible for keeping your email account and your devices secure, and for what happens under your account until you sign out. Tell us at [email protected] if you believe someone else has access. You may sign out of any device, download your data, or delete your account at any time from the account button in the app.
4. Acceptable use
Please don't: break the law; probe, scan, overload or disrupt the Service or other people's accounts; access the Service with automated tools other than the app itself in a way that imposes unreasonable load; try to get at other users' data; upload content you have no right to store or that is unlawful; or offer the hosted Service, or a substantially equivalent copy of it, to third parties as your own product. We apply technical limits (for example, rate limits and size limits) to protect the Service; they are designed to be invisible in ordinary use.
5. Your content is yours
You own the practice data, notes, score files and everything else you put into Chopinly. You grant us only the limited license needed to store, back up, sync, transmit and display it to you and your other devices in order to provide the Service. That license ends when you delete the content or your account. We do not sell your content, share it with anyone for their purposes, or use it to train machine-learning models.
Sheet music. Upload only music you have the right to keep a personal copy of — editions you bought, public-domain scores, your own manuscripts and arrangements. Uploaded files are private to your account: they are never shared with other users, listed, indexed or published, and only your own signed-in devices can fetch them. Each account has a storage allowance shown in the app, which we may change with notice. If you are a rights holder and believe a file in someone's private space infringes your rights, write to [email protected] with enough detail to identify the work and your claim; on a valid notice we remove the file and inform the account holder, who may respond to us in turn.
6. The Service is free, and provided as it is
Chopinly costs nothing and shows no advertising. We may add, change or remove features over time. We operate the Service with care — including database backups and managed infrastructure — but it comes with no uptime guarantee. If we ever decide to end the hosted Service, we will give account holders at least 30 days' notice by email and in the app, and the download button will keep working through that period so you can take your data with you. After that, remaining account data is deleted.
7. The code and the Service are licensed differently
Chopinly's source code is licensed under the Elastic License 2.0, which lets you use, modify, self-host and build on the software but not offer it to others as a hosted service. That license governs the code. These Terms govern your use of the hosted Service at chopinly.com. "Chopinly" and the Chopinly mark are our trademarks and are not licensed by either.
8. Disclaimer of warranties
The Service is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. Chopinly is a tool, not a teacher or a health professional; see the Disclaimer. Some jurisdictions do not allow certain warranty exclusions, so some of this may not apply to you.
9. Limitation of liability
To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost data, lost profits or goodwill, arising out of or relating to the Service. Because the Service is free, our total liability to you for any claim relating to it is limited to fifty US dollars (USD 50) or the smallest amount permitted by law, whichever is greater. Nothing in these Terms limits liability that cannot be limited by law, including for gross negligence, willful misconduct, or, where you are a consumer, rights that your local law gives you and does not allow to be waived.
10. Your responsibility to us
You will hold us harmless from claims by third parties that arise from content you store in the Service or from your breach of these Terms.
11. Ending things
You can stop using Chopinly at any time, and delete your account in the app; deletion is immediate. We may suspend or close an account that breaks these Terms or threatens the Service or other users; where reasonable we will warn you first, and you can always ask for your data.
12. Governing law and disputes
These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-law rules. Disputes will be resolved in the state or federal courts located in Delaware, and each of us waives any right to take part in a class action. If you are a consumer in the European Union, the United Kingdom or elsewhere with mandatory consumer-protection rules, nothing here takes away the protections of the law of your country of residence or your right to bring a claim in your local courts.
13. Changes to these Terms
We may update these Terms. Material changes will be announced by email to account holders or in the app at least 14 days before they take effect; the effective date at the top will change. Continuing to use the Service after that date means you accept the new Terms.
14. The whole agreement
These Terms, together with the Privacy Policy, Cookie Policy and Disclaimer, are the entire agreement between you and us about the Service. If any part is found unenforceable, the rest stands. You may not transfer this agreement; we may transfer it in connection with a merger or sale, and you would be told.
