Master Split is a one-time purchase, perpetual license for the macOS application (Apple Silicon), licensed per the EULA for use on one Mac. Price is shown at checkout (taxes/VAT may apply by location). Payment is processed by Stripe; we do not receive your card details. Your license key is delivered by email, typically within minutes of purchase. Keep it safe — it is your proof of license.
The demo provides the full application for 1 day, one demo per person/email. We may use technical measures (e.g., per-email and per-IP limits) to prevent demo abuse and may refuse or revoke demos obtained by circumventing them.
We offer a 14-day money-back guarantee: if Master Split isn't right for you, email support@mastersplit.app within 14 days of purchase for a full refund, no questions asked.
Refunded purchases result in the associated license key being deactivated. Chargebacks on legitimately delivered licenses likewise result in key revocation.
Activation, machine binding, and license transfer depend on our license server. We aim for high availability but do not guarantee uninterrupted service; the desktop application is designed to operate offline for up to 30 days between validations. If we permanently discontinue the license service, we will issue a final update that removes online validation so installed copies keep working.
You agree not to: resell or redistribute license keys; use the service to obtain keys fraudulently; probe, overload, or disrupt the license server or website; or violate applicable law in connection with your purchase or use.
The Software requires an Apple Silicon Mac and a supported macOS version, as stated on the website at the time of purchase. We do not guarantee compatibility with future macOS versions indefinitely, though we endeavor to keep the product current (see EULA §7).
The website, the Master Split name and branding, and the Software are our property or licensed to us. Open-source components are credited in the User Manual and governed by their own licenses.
The website and license service are provided "as is". OUR TOTAL LIABILITY RELATING TO ANY PURCHASE IS LIMITED TO THE AMOUNT PAID; NO INDIRECT OR CONSEQUENTIAL DAMAGES, TO THE MAXIMUM EXTENT PERMITTED BY LAW. Statutory consumer rights (including in the EU/UK/Australia) are not affected where they cannot be waived.
Governed by the laws of New York; venue New York, NY.
We may update these terms; the version in force at your time of purchase governs that purchase. Material changes will be posted on the website with the updated date.
