Refund Policy

Web Harmonium is a completely free, browser-based instrument. There are no subscriptions, premium tiers, or paid features — you never need to provide payment information to use the Service.

Because no purchases are made through webharmonium.space, there is nothing to refund. This policy exists solely to be transparent about that fact.

If you purchased a product or service from a third party that directed you to Web Harmonium (for example, a course, book, or educational bundle), please contact that third-party seller directly for refund assistance. We have no visibility into or control over third-party transactions.

If you voluntarily made a donation to support the project and believe an error occurred (e.g., duplicate charges), please contact us immediately with your transaction details. We will work with the payment processor to resolve the issue as quickly as possible.

If you have any questions about this policy, please reach out to us. We typically respond within 1–3 business days.
