Tactile Terms of Service
Last updated September 13, 2026
Tactile is made by one person. These terms are the plain version of the deal: you get to use the app for free, and you accept that it is software, not a promise that nothing will ever go wrong.
who you are agreeing with
Tactile is developed and published by Mason (LeShan) Chen, an independent developer trading as masn.studio. In these terms, "Tactile" means the Tactile app for Mac, the Tactile Browser Bridge extension for Chrome, and this website. By installing or using Tactile you agree to these terms. If you do not agree, do not use it.
what tactile is
Tactile is a menu bar app that plays haptic feedback on your Force Touch trackpad when the pointer reaches something clickable, with optional visual aids, keyboard haptics, sound alerts, and music haptics. It needs the Accessibility permission on your Mac to do this, and Feel the Music also needs the System Audio Recording permission. You control those grants and can revoke them at any time in System Settings.
your license
Tactile's source code is released under the MIT License. It lets you use, copy, modify, and share the code, and nothing in these terms takes any of that away. These terms cover the builds I publish, the Chrome extension, and this website.
price
Tactile is free. There is no paid tier, no in-app purchase, no subscription, and no ads. The optional tip link in the app goes to Buy Me a Coffee, which handles the payment, so I never see your payment details. A tip does not unlock anything.
your responsibilities
Tactile is an aid, not a safety system. Do not rely on it as your only way to notice a call, an alert, or a destructive button. A tick can be missed, and apps do not always describe their controls correctly. Only use Tactile on Macs you own or are allowed to set up.
the mac app and updates
Tactile is distributed outside the Mac App Store, because the system-wide Accessibility access it needs is not permitted inside Apple's sandbox. It is signed with an Apple Developer ID and notarized by Apple. It checks for updates using Sparkle and asks before installing one, unless you choose automatic installs. Only download it from this site or from the official GitHub releases page it links to.
the chrome extension
The Tactile Browser Bridge is optional. It is distributed through the Chrome Web Store, which has its own terms from Google.
changes to the app
Tactile is actively developed. Features may be added, changed, or removed, and macOS updates can break things outside my control. Enhanced haptics and Feel the Music use parts of macOS that Apple does not document, so they may stop working after an update. When that happens, Tactile falls back to standard haptics.
privacy
Tactile collects no personal data. There is no account, no analytics, and no Tactile server. The full explanation is in the privacy policy, which is part of these terms.
no warranty
Tactile is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement. I do not warrant that it will be uninterrupted, error free, or compatible with every app, device, or trackpad.
limitation of liability
To the fullest extent the law allows, I am not liable for indirect, incidental, special, or consequential damages, or for lost data, lost work, or lost profits arising from your use of Tactile. Tactile is free, so total liability for any claim is limited to the amount you paid for it. Some jurisdictions do not allow these limits, so parts of this section may not apply to you.
apple and google
Tactile is not made or endorsed by Apple or Google. Mac, macOS, and Force Touch are trademarks of Apple Inc., and Chrome is a trademark of Google LLC.
ending it
You can stop using Tactile at any time by quitting it, deleting the app, and removing the extension from Chrome. These terms end for you if you break them, though that never limits what the MIT License lets you do with the source code. The sections about warranty and liability survive.
governing law
These terms are governed by the laws of the Commonwealth of Massachusetts, United States, without regard to its conflict of law rules, and any dispute will be handled in the state or federal courts located in Middlesex County, Massachusetts. If you are a consumer somewhere with stronger local protections, this does not take those away.
changes to these terms
If these terms change, the new version will appear on this page with an updated date. Continuing to use Tactile after that means you accept the change.
