Product and price

PortLine is downloadable macOS software for transferring files between a Mac and supported Android devices.

Website prices are US$11.40 per year or US$20.40 once for lifetime Premium. A three-day trial requires a payment card and automatically renews at US$11.40 per year unless canceled before it ends. One trial per email address. Applicable tax is displayed at checkout. Cancel future renewals through Manage billing; deactivating a Mac does not cancel billing.

A website license activates one Mac at a time. Premium works offline: a Lifetime license for up to a year at a time, a yearly plan through its paid period plus 7 days while it renews, and a trial until it ends. PortLine refreshes access automatically whenever it is open and online. Recover a lost key by signing in with your purchase email. Replacing a key resets its Mac binding; a Mac that stays offline keeps already-issued access until it next connects or that access’s offline period ends. Lifetime is a one-time license for the supported lifetime of the product, not a promise of perpetual platform compatibility.

Additional charges

There are no shipping charges for digital delivery. Any applicable tax is shown before payment. You are responsible for internet access, required hardware such as a data cable, and any currency conversion or other fees charged by your payment provider.

Payment methods and timing

Accepted payment methods are credit and debit cards, and Cash App Pay for eligible customers in the United States. Checkout shows the methods available in your country.

Website checkout uses Stripe Managed Payments; the seller of record and applicable terms are shown at checkout. Yearly payment is collected at purchase, or after the three-day trial, and each renewal; lifetime payment is collected once. App Store purchases remain billed and managed by Apple.

Delivery and activation

Download the app from our website. After a successful payment or trial registration, sign in with the same email to view your license and activation instructions. Delivery is electronic; no physical item is shipped. Contact support if your purchase or activation does not appear.

Trial, cancellations, and refunds

The three-day trial requires a payment card. If you cancel before the trial ends, you are not charged; otherwise it renews at US$11.40 per year. Canceling a yearly plan stops future renewals, and Premium stays available until the end of the paid period. Cancel at any time through Manage billing; deactivating a Mac does not cancel billing.

Use the trial to check compatibility before committing. If a refund is necessary, contact [email protected] with your order and issue for individual review. This does not limit mandatory consumer rights or Stripe Managed Payments’ applicable refund rights and policies. App Store refunds follow Apple’s process.

System requirements

macOS 13 or later. USB connections require a supported Android device running Android 8 or later; Secure Wi-Fi requires Android 11 or later with wireless debugging support and the same local network. Compatibility depends on the device, cable, network, and manufacturer settings. Sufficient local storage is needed for the app, cached files, and transfers. Check compatibility using the trial before purchase.

App Store purchases

This disclosure’s website payment, delivery, and refund information applies to purchases made on the PortLine website. Purchases through the Mac App Store are billed by Apple and follow Apple’s purchase and refund processes.
