Terms of Use & License

1. Acceptance of these terms

These Terms of Use (the “Terms”) are an agreement between you and Clearware, LLC(“we,” “us”) covering your use of the CardTray application and this website. By installing, launching, or using CardTray, you agree to these Terms. If you do not agree, do not install or use the app.

2. License to use the app

Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use CardTray on devices you own or control. You may not resell, rent, or redistribute the app, and you may not attempt to reverse engineer, tamper with, or circumvent its safeguards except to the extent the law expressly permits.

3. The idle-bandwidth exchange (a condition of use)

CardTrayis provided free of charge, and it is funded by sharing a slice of your device's idle, unused internet bandwidth — when it can— through Massive, our vetted partner. This exchange is what pays for development instead of a subscription, paid card decks, or advertising, and it is a condition of using the free app.

• Participation is disclosed to you at install time, before anything runs.
• Only one Clearware app shares on a device at a time. Massive's network allows a single connected client per machine. If you have another Clearware application installed, only one of them shares at any moment; the other keeps trying and takes over once the slot frees up. On a device where a sibling app holds the slot, CardTraymay share nothing for as long as that lasts. We say “when it can” because of this limit, not as a hedge — CardTray does not itself throttle, schedule or withhold sharing.
• Sharing runs in the background and continues after you close the app, for as long as you are signed in to Windows, until you turn it off or uninstall. It runs only for the signed-in user.
• The bandwidth sharing carries Massive's ordinary web traffic. It does not read, transmit, or otherwise access your saved games, replays, scores or records, the files on your disk, your browsing history, your credentials, or your screen.
• To operate the network, Massive processes a limited set of device data — your IP address during active sessions, an anonymous device identifier, city-level location, device specifications, and bandwidth statistics — as an independent data controller under its own privacy policy.
• You may turn sharing off at any time from the app's Settings, its tray menu, or Massive's own tray icon. The games do not run while sharing is off. You cannot start or continue a game, and a game on screen when sharing stops is paused rather than ended. It was saved on its last move, so nothing is lost, and it resumes at the same move once sharing is back on. Your saved games, stats, records and replays stay readable while sharing is off. Uninstalling ends participation completely and removes the Massive agent (section 7).
• There is no automatic pausing on metered connections, no automatic back-off while you are using the network, and no bandwidth cap.

Full details are on How it's funded, and privacy details are in our Privacy Policy.

4. Your responsibilities

CardTray is a single-player game library that runs on your own computer. You are responsible for how you use it. In particular:

• Your game data is yours to keep. CardTrayhas no accounts and no cloud sync, so your saved games, replays, records and achievements exist only in the app's folder on that computer. Uninstalling leaves them in place; deleting that folder removes them permanently, and we hold no copy from which to restore them.
• Scores, streaks, personal bests and achievements are personal records kept on your device. They have no monetary value, cannot be exchanged or redeemed for anything, and are not entries in any contest. CardTray involves no wagering and no prizes.
• You must not use the app to gain unauthorised access to any system, to interfere with a service, to infringe intellectual property, to invade privacy, or for any unlawful purpose.

5. No warranty

CardTrayis provided “as is” and “as available,” without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the app will be uninterrupted or error-free, or that any particular deal can be won. Many solitaire deals cannot be won; only Daily Challenge deals are checked as winnable before they are offered. The solver may be unable to reach an answer for a position and say so, and its answers assume every card is known. Games marked Beta are still being checked and their rules may change in an update; a game saved or finished under earlier rules may then be locked, so that it can no longer be continued or replayed move by move, although the same deal can always be dealt again.

6. Limitation of liability

To the maximum extent permitted by law, Clearware, LLC will not be liable for any indirect, incidental, special, or consequential damages, or for any loss of data, arising out of or related to your use of CardTray. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

7. Uninstalling and ending these terms

You may stop using CardTray at any time. Uninstalling the app is the way to opt out of the idle-bandwidth exchange and end these Terms — there are no dark patterns and nothing to cancel. Once the app is removed, bandwidth sharing stops. We may also suspend or end your license if you materially breach these Terms.

8. Changes to these terms

We may update these Terms as the product evolves. When we make material changes, we will revise the “last updated” date above and, where appropriate, notify you in the app or on this site. Continuing to use CardTray after changes take effect means you accept the updated Terms.
