The agreement between us, in plain English.

1. What you're agreeing to

These terms ("Terms") govern your use of DomiSol, the marketing site at domisol.app, the editor at dash.domisol.app, and any related service (collectively, the "Service"). By signing in or using the Service, you agree to these Terms. If you don't, please don't use the Service.

2. Plans and the free tier

DomiSol has a free tier and paid plans. That means:

• Writing, playing back, sharing and printing your scores in solfa or jianpu are free, and stay free. There will always be a free tier.
• Paid plans and AI credits unlock the rest, chiefly the AI features, which cost us real money per use. What each plan includes is listed on the pricing page, and your current allowance is shown in the editor.
• Features may change, break, or be removed. If we remove something you are paying for, we'll email you first.
• Data loss is unlikely (we run automated backups) but is not impossible, keep important scores exported to PDF.
• We may impose reasonable rate limits or usage caps to keep the Service stable.

2a. Payment, renewal and refunds

Payments are processed by Polar, our merchant of record, who handles billing and any applicable sales tax or VAT. Subscriptions renew automatically at the then-current price until you cancel, which you can do at any time from the billing portal; cancelling stops the next renewal and you keep your plan until the end of the period already paid for.

Purchases made in the iOS or Android app are billed by Apple or Google through your store account, not by Polar. A subscription bought there renews automatically until you cancel it in your store account settings, at least 24 hours before the end of the period, and refunds for those purchases are handled by the store under its own policy. A plan bought on either side belongs to your DomiSol account and works in the app and on the web.

AI credits are consumed as you use AI features and do not expire. Credits already spent are not refundable. If something we charged you for did not work, email us, we would rather fix it than argue about it.

3. Your account

You're responsible for the activity on your account. Pick a strong password (or sign in with Google). Don't share your credentials. Tell us at hello@domisol.app right away if you think your account was compromised.

You must be at least 13 years old to create an account.

4. Your content

You own everything you create on DomiSol. Scores, lyrics, arrangements, they're yours. We claim no ownership over any of it.

You grant us a limited licence to host, render, and serve your content for the purpose of operating the Service (we have to be able to display your scores back to you). When you publish a score publicly, you also grant us the right to serve it to anyone who follows the share link.

You promise that you have the right to upload everything you upload, that you're not infringing someone else's copyright or trademark.

5. Acceptable use

You agree not to:

• Use the Service to do anything illegal or to facilitate illegal activity.
• Upload content that infringes third-party rights or that is hateful, harassing, or obscene.
• Probe, scan, or test vulnerabilities of the Service without our written permission.
• Try to extract the source data of other users' private scores.
• Resell access to the Service or scrape it for commercial purposes.

6. Intellectual property

The DomiSol name, logo, and the editor's UI design and code belong to us and are protected by copyright and trademark laws. You may not copy them. (Open-source components we use are listed at /oss/, those are governed by their own licences.)

7. Termination

You can delete your account anytime by emailing hello@domisol.app. We can suspend or terminate your account if you violate these Terms; in non-egregious cases we'll give you a chance to fix the issue first.

8. Disclaimers

The Service is provided "as is", without warranty of any kind. We try to keep it running smoothly, but we don't guarantee it will be uninterrupted or error-free. Audio playback uses your browser's Web Audio API, fidelity depends on your hardware and OS.

9. Liability

To the maximum extent allowed by law, our total liability for any claim related to the Service is capped at the amount you paid us in the 12 months preceding the claim (which, on the free tier, is zero). We're not liable for indirect, consequential, or incidental damages.

10. Pricing changes

We give all signed-in users at least 14 days' notice by email before any pricing change takes effect, and there will always be a free tier. A price you are already subscribed at does not change under you: founding members keep their locked rate for as long as the subscription stays active.

11. Changes to these Terms

We may update these Terms occasionally. If we make material changes, we'll email signed-in users and update the date at the top of this page. Continued use of the Service after the effective date means you accept the changes.

12. Governing law

These Terms are governed by the laws of the jurisdiction in which DomiSol is incorporated. Any dispute that can't be resolved by email will be resolved in the courts of that jurisdiction.
