Terms of Use

1. About these Terms

Yafei Wang provides Tick: Simple To-Do ("Tick" or the "app"). These Terms describe use of its task-management features, optional sync, reminders and support on macOS and iPhone. Features and availability can differ by platform, app version and region. Contact yfeiib@gmail.com with questions.

Use the app in accordance with these Terms and applicable law. If you use it for an organization, you must have authority to do so. If you cannot legally agree to these Terms on your own, obtain the permission or supervision required by applicable law.

2. App Store license and purchases

For downloads through the App Store, Apple’s applicable transaction terms and the Apple Standard Licensed Application End User License Agreement govern the app license unless a separate custom license is expressly provided through the App Store. These Terms add information about Tick’s features and do not replace that license, Apple’s Usage Rules or rights you cannot waive under applicable law.

Use Tick on Apple devices you own or control as allowed by the applicable license. Do not unlawfully redistribute the app, remove proprietary notices, or reverse-engineer it except where applicable law or an included open-source license permits. Any download charges, purchases or refunds are handled under the relevant App Store transaction and Apple’s rules. Tick does not collect payment-card information.

3. Your content and responsible use

You retain rights to tasks, notes, lists, links and other content you create. Tick processes that content to provide the features you use. We do not claim ownership of it or a right to publish it. You must have the rights needed to store the content and must not use Tick to violate laws, other people’s rights or the security of the app or connected services.

You are responsible for the accuracy of your task details, dates, repeat rules and instructions, for protecting access to your devices and Apple Account, and for keeping backups of important content.

4. Local data and optional iCloud sync

Core task management works locally without a separate Tick account. Where supported, iCloud sync is optional and requires a compatible version of Tick, an available Apple Account with iCloud access, sufficient storage and connectivity. Connected devices must use the same Apple Account and compatible versions of Tick.

Cloud synchronization is scheduled by the operating system and Apple services. We do not promise immediate updates, uninterrupted availability or that every conflicting edit will be retained exactly as entered. Check important changes on your devices and keep independent backups. Account changes can pause sync to protect existing local content.

Turning sync off retains local content and does not erase data already in iCloud. With sync enabled, deletions can propagate to other connected devices. Uninstalling the app does not necessarily remove all local data, cloud records or backups. Follow the app’s controls and system settings when managing data. Cloud recovery or rebuilding from a device can upload that device’s retained content again.

5. Dates, reminders and notification limits

Tick can schedule local reminders when you permit notifications. Notification timing and visibility depend on system permissions, Focus modes, device state, time-zone changes and operating-system scheduling. Reminders may be delayed or missed, and previously missed reminders are not necessarily delivered later. Each device has its own reminder preferences.

Tick is not an emergency alarm, safety-critical alert system or substitute for independent arrangements for time-sensitive obligations. Check due dates and reminder settings, and use an appropriate backup reminder when timing is important.

6. External services and links

The Mac app may show weather and daily quotes from external providers. Such content may be inaccurate, incomplete, unavailable or unsuitable for a particular purpose. Weather estimates are approximate. External websites, Apple services and content providers have their own terms and privacy practices. Your use of those services is subject to their applicable terms. Tick does not control their uptime, retention or processing locations.

7. Privacy

The Privacy Policy explains local storage, optional iCloud sync, notifications, Mac online content requests and support correspondence. The same policy URL is used for Mac and iPhone. Accepting these Terms does not automatically enable iCloud sync, grant system notification permission or authorize a purchase.

8. Updates and availability

We may provide fixes and change features, supported operating systems or service integrations. Apple and external services may also change their interfaces or availability. We do not promise a particular future feature or a fixed support period. Install updates when appropriate and back up important content before changing devices or versions. Material changes to terms will be communicated as required by applicable law.

9. Warranties, liability and consumer rights

To the extent permitted by applicable law, Tick and external content are provided on an "as is" and "as available" basis without a promise of uninterrupted or error-free operation or fitness for a particular purpose. You should not rely on Tick as your only copy of important information.

To the extent permitted by law, we are not responsible for indirect or consequential losses caused by factors such as external service outages, missed notifications or failure to keep backups. Nothing in these Terms excludes or limits liability that cannot legally be excluded or limited, including liability for fraud or any other mandatory protection under applicable law. Your statutory consumer rights and the applicable App Store license remain unaffected.

10. Ending use

You can stop using Tick at any time. If you uninstall it, first export or back up content you need and separately manage any retained iCloud data or backups. Ending use does not automatically erase information held by Apple or external providers. Any termination of the app license follows the applicable license and law.

11. Applicable rules and updates to these Terms

These Terms are subject to applicable law and do not remove mandatory rights or dispute-resolution options available where you live. Apple’s separate agreements continue to govern App Store and Apple-service use. We will publish revised Terms at this same Terms URL with an updated date and provide any notice required by law.
