Frequently Asked Questions (FAQ)

Q. Why is installing the Privileged Helper required?

A. To switch macOS's standard packet filter (pf) and sharing settings, administrator privileges through Apple's official SMAppService are needed once, at the beginning. Once you allow it, it runs automatically from then on without asking for a password.

Q. Does RoamSwitch impact battery life?

A. The load on battery and CPU is practically zero. It does no constant polling and runs only when it receives macOS network state change events (SCDynamicStore).

Q. Is Apple Silicon (M1/M2/M3/M4) supported?

A. Yes. RoamSwitch is built exclusively for Apple Silicon (M1 / M2 / M3 / M4 and later). * Intel Macs are not supported.

Q. Can I get a refund after purchase?

A. As a digital product, refunds and cancellations are not accepted. Please use the free version first to confirm it works in your environment and doesn’t disrupt your workflow. Customers in the EU and UK consent to immediate delivery and waive the statutory right of withdrawal at checkout. To report a defect in RoamSwitch, contact us via the form above (refunds and cancellations are not available for defects either).

Q. You’re a solo developer — what happens to my license if development stops?

A. Pro licenses are validated fully offline, so activated devices keep working even if our server goes away. If the product is discontinued we keep the final signed build available, and the key components (MCP server, detection logic, SDK) are already on GitHub under the MIT license. See “Business Continuity & End-of-Life Policy” on the Legal page for details.

Reporting a security issue

If you find a vulnerability in RoamSwitch itself or in lafine.net, please contact us through the contact form above and choose “Bug / Bug Report” (it helps if the subject or body includes “security”). Please refrain from disclosing it until a fix is published. We will not take legal action against good-faith security research. As a rule, we will acknowledge receipt within 5 business days.
