Terms
These terms explain the rules for using the Callsign Mac app and website. Callsign is intentionally small: it creates visible aliases in a folder you choose so familiar names can open native Mac tools.
Effective date: June 5, 2026
By downloading, installing, purchasing, accessing, or using Callsign or the Callsign website, you agree to these Terms and Conditions. If you do not agree, do not use Callsign.
In these terms, "Callsign," "we," "us," and "our" refer to the Callsign app publisher identified in the Mac App Store listing. "You" means the person using the app or website.
Callsign is a small macOS utility for people switching from Windows to Mac. It creates visible Finder aliases in a folder you choose, so familiar labels such as Task Manager, Control Panel, File Explorer, Snipping Tool, and Paint can open native Mac tools such as Activity Monitor, System Settings, Finder, Screenshot, and Preview.
Callsign is not a launcher, Spotlight replacement, emulator, migration assistant, background indexer, system modification tool, or file indexing service.
Callsign is distributed through the Mac App Store. Your download, purchase, Family Sharing eligibility, refunds, taxes, payment method, and Apple Account are handled by Apple under the Apple Media Services Terms and other Apple rules that apply to your country or region.
Unless the Mac App Store listing says otherwise, Callsign is intended to be offered as a paid-up-front app with no subscription, no account, and no in-app advertising. Prices, taxes, availability, refunds, and promotions may vary by storefront and may change over time through Apple.
Subject to these terms and Apple's applicable App Store terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to install and use Callsign on Apple-branded devices you own or control, solely for your own personal or internal use.
You do not acquire ownership of Callsign, its website, its name, its design, its source code, its text, or its bundled alias catalog.
You are responsible for:
Callsign creates visible alias files only where you approve them. You can inspect, move, rename, or remove those files using Finder, and Callsign may provide a removal flow for managed aliases it created.
macOS search ranking, Spotlight indexing, Finder behavior, and native app availability are controlled by macOS and may vary by machine, operating system version, selected folder, user settings, and time. Callsign does not guarantee that an alias will appear first in search results, appear immediately after creation, appear as an application, or behave exactly like a Windows tool.
Callsign creates aliases to native Mac tools; it does not install Microsoft apps, Windows apps, or replacements for macOS system features.
We may update, improve, remove, suspend, or discontinue Callsign or the website at any time. Updates may change supported aliases, native app mappings, interface text, compatibility, pricing, or availability. Some updates may be required for compatibility with future macOS or App Store requirements.
You may not:
Callsign, the Callsign website, app text, design, and other original materials are owned by the Callsign publisher or licensed to us and are protected by intellectual property laws.
Microsoft, Windows, Apple, Mac, macOS, Finder, Spotlight, App Store, and other names may be trademarks of their respective owners. Callsign is independent and is not affiliated with, endorsed by, sponsored by, or approved by Microsoft or Apple. Product and tool names are used only to describe familiar labels and the native Mac apps they open.
The Callsign website and support process may rely on or link to third-party services, including Apple for Mac App Store distribution and purchases, Cloudflare for website hosting and delivery, email providers for support, and third-party websites linked from the site. Those third parties have their own terms, privacy policies, support rules, and availability. We are not responsible for third-party services or websites.
Your use of Callsign is also covered by the Privacy Policy. The short version is that Callsign is designed with no account, no analytics, no telemetry, no tracking, no network dependency, and local aliases only.
Support information is available on the support page. We try to provide helpful support, but we do not promise any specific response time, resolution, future feature, compatibility update, or continued availability.
To the maximum extent allowed by law, Callsign and the website are provided "as is" and "as available" without warranties of any kind, whether express, implied, or statutory. We do not warrant that Callsign will be uninterrupted, error-free, secure, compatible with every Mac or macOS version, suitable for your needs, or that every alias mapping will be complete, current, or exact.
Some jurisdictions do not allow certain warranty exclusions, so some exclusions may not apply to you.
To the maximum extent allowed by law, Callsign, its publisher, and any contributors are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost data, loss of goodwill, device issues, business interruption, or substitute services arising from or related to Callsign or the website.
To the maximum extent allowed by law, our total liability for any claim related to Callsign or the website will not exceed the amount you paid for Callsign in the twelve months before the claim, or USD $10 if you paid nothing.
Nothing in these terms limits liability where the law does not allow that limitation.
If you use Callsign or the website in violation of these terms or applicable law, you agree to be responsible for claims, losses, liabilities, damages, costs, and expenses, including reasonable attorneys' fees, arising from that misuse, to the extent allowed by law.
You may stop using Callsign at any time and may remove aliases and app data from your Mac using normal macOS controls. Because Callsign is a local Mac app with no account and no network dependency, we do not remotely disable your installed app through a Callsign account. We may stop providing the website, support, future updates, or future App Store availability. Apple's terms may also affect your App Store access, downloads, purchases, or refunds. Sections that by their nature should survive termination will survive, including intellectual property, disclaimers, limitations of liability, indemnity, governing law, and dispute terms.
These terms are governed by the laws of the State of New York, United States, excluding conflict-of-law rules, unless the consumer protection laws of your location require another law to apply. Courts located in New York will have jurisdiction for disputes that are not required to be brought elsewhere by applicable law.
We may update these terms from time to time. The effective date at the top shows when the terms were last updated. If we make material changes, we may provide notice through the website, App Store listing, app update notes, or another reasonable method. Continued use after updated terms become effective means you accept the updated terms.
