Licensing Knowledge Base
Pricing & Licensing FAQ
Clear, honest answers about activations, migrations, renewals, and licensing terms.
How many Macs can I activate with my license key?
Free can be used on 1 Mac. Pro activates 1 Mac concurrently. The Lifetime license includes activations for up to 3 personal Macs. The Founder Edition includes activations for up to 2 Macs. If you ever switch or upgrade hardware, you can instantly detach an old machine and re-assign the seat.
Can I transfer my license to a new Mac when I upgrade my computer?
Yes! License migration is instant and frictionless. Inside Silo's Settings > License screen, you can click 'Deactivate this Mac' with a single click. Alternatively, log into your Customer Portal to view all active hardware identifiers and remotely release any device seat.
What happens if I decide not to renew my Pro annual subscription?
Silo will never lock you out of your machine or hold your settings hostage. If you choose not to renew after your 1-year Pro cycle, Silo seamlessly continues operating on the Free tier. You retain full access to storage treemaps, port inspection, and system metrics.
How does the Lifetime license handle major macOS upgrades like macOS Sequoia?
Lifetime licenses are truly perpetual. When Apple ships major annual macOS versions (macOS Sonoma, Sequoia, and future releases), your Lifetime license key remains 100% valid with all updates and compatibility patches included forever.
What makes the Founder Edition special?
Founder Edition is strictly capped at the first 500 engineers who support Silo. For $25 one-time, Founders receive a perpetual lifetime license on 2 Macs, a commemorative numbered badge rendered inside the Silo interface, private early access to experimental build channels, and direct voting rights on future utility priorities.
What payment methods are supported and how does Paddle work?
We partner with Paddle as our Merchant of Record to deliver secure global payments. We accept Apple Pay, Google Pay, Visa, Mastercard, American Express, and PayPal. Paddle automatically handles global VAT, sales tax, and sends an official VAT invoice directly to your billing email.
What is your refund or return policy?
We offer a 100% money-back guarantee for 14 calendar days from your purchase date on all paid plans (Pro, Lifetime, and Founder). If Silo doesn't solve your developer workflow needs, clear your Docker bloat, or reclaim the disk space you expected, simply email sparoconnect@gmail.com or use the in-app Help menu for an immediate, no-questions-asked refund.
Does Silo collect telemetry, user analytics, or phone home?
Never. Silo is built on a foundational zero-telemetry principle. All APFS filesystem operations, process audits, and disk indexing occur 100% locally on your Mac using native Darwin APIs. We do not incorporate Google Analytics, Firebase, Mixpanel, or any tracking SDKs.
