Welcome to FocusLeaf. This End-User License Agreement and Terms of Service (the "Agreement") is entered into by and between the developer of FocusLeaf (hereinafter referred to as "we", "us", or "Licensor") and the user who downloads, installs, or uses this software (hereinafter referred to as "User" or "you").

FocusLeaf is a local utility application designed for individuals and organizations to restrict, control, or manage the usage of specific websites, applications, or computer devices to help users reduce distractions and improve focus (the "Service" or "Software Service"). The Software and Service are provided via the official website (including but not limited to focusleaf.today, collectively, the "Site") and related channels.

PLEASE READ THIS AGREEMENT CAREFULLY. BY INSTALLING, COPYING, RUNNING THE SOFTWARE, OR USING ANY PART OF THE SOFTWARE SERVICE, YOU ACKNOWLEDGE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE BOUND BY ALL THE TERMS OF THIS AGREEMENT. IF YOU DO NOT AGREE TO THE TERMS OF THIS AGREEMENT, EXIT THIS PAGE IMMEDIATELY, STOP THE INSTALLATION, UNINSTALL AND DELETE THE SOFTWARE, AND DO NOT ACCESS OR USE THE SOFTWARE SERVICE.

1. Service Description & Restrictions

1.1 Target Audience and Age Restrictions

The Service is intended for users who are at least thirteen (13) years of age. Use of the Service by anyone under the age of thirteen (13) is a violation of this Agreement.

1.2 Personal and Non-Commercial License

We grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and run the Software solely for your personal and non-commercial use.

1.3 Account Security

If the Software Service requires the purchase of a license activation key, you are responsible for maintaining the confidentiality of your license activation key and the associated email address used to retrieve it, and you are fully responsible for all activities that occur under your license key. You acknowledge and agree that once a license activation key is bound or linked to a specific email address, if your security email address is lost, closed, or becomes inaccessible due to your personal reasons, resulting in the inability to retrieve or use the license, any associated losses shall be borne solely by you, and we do not provide manual license transfer or re-issuance services.

2. Explicit Authorization for System Modifications

In order to achieve core focus features such as restricting access and enforced distraction blocking, by installing and running the Software, you are deemed to have explicitly acknowledged, authorized, and agreed to the Software performing the following necessary operations on your local device:

  • Modifying local system configuration files;
  • Changing or configuring local system proxy settings;
  • Managing, intercepting, closing, or restricting the display status of specific local applications, processes, and system windows;
  • Intercepting, blocking, or redirecting specific network access or browser webpage access;
  • Executing system-level lock screen, forced logout, forced restart, or forced shutdown commands in accordance with the focus plans you set.

3. Locked Plan, Device Locking & Voluntary Activation

3.1 Acknowledgment of Locking Feature

You acknowledge and agree that once a locked plan or device lock of the Software is enabled, it cannot be manually interrupted, bypassed, or immediately unlocked before the scheduled duration expires.

3.2 Duty of Reasonable Evaluation

Prior to starting any focus session, you must evaluate and confirm on your own that there are no urgent tasks, critical communications, system maintenance, or other non-deferrable needs during the locked period.

3.3 Waiver of Liability

In the event that you voluntarily enable the enforced restriction features, causing you to be unable to access or fully use your computer or network in an emergency, we shall not be liable for any resulting loss of opportunity, missed meetings, academic/exam failure, business delay, or any other adverse consequences.

3.4 Disclaimer for Custom Block Pages

  • (a) Custom Code and Scripting at Your Own Risk: The Software allows you to upload, configure, and run custom HTML pages and JavaScript scripts. You explicitly acknowledge that scripts such as JavaScript have the capability to execute arbitrary web-side code. You assume sole responsibility for the security, safety, and compliance of any custom pages and code that you write, upload, or run.
  • (b) Risks of Importing Third-Party Shared Pages: The Software supports importing custom block pages shared by other users or through third-party channels. We do not perform security audits, virus checks, or code reviews on any block pages created, shared, or distributed by third parties. Importing and using pages shared by others may present security risks (including but not limited to malicious script injection, sensitive information leakage, browser redirection fraud, excessive consumption of local resources, etc.). Before importing any third-party page, you must inspect and verify the security of its code on your own. We shall bear no direct or indirect legal liability for any device damage, data breach, network attack, or any other security incident arising from importing or running third-party shared pages.

5. Purchases & Refunds

5.1 Merchant of Record & Third-Party Terms

The sale, payment processing, transaction handling, tax calculation, and billing for the Software are managed solely and independently by third-party payment service providers, distributors, or platforms (such as Paddle, Lemon Squeezy, etc., collectively "Third-Party Payment Processors") acting as the "Merchant of Record." When purchasing a license activation key, your contract for purchase is concluded directly with such Merchant of Record. You must abide by the relevant terms of service, transaction rules, and privacy policies of these third-party platforms.

5.2 Third-Party Payment Disclaimer

You explicitly acknowledge and agree that we are not a party to any transaction between you and any Third-Party Payment Processor. We shall not under any circumstances be liable for any transaction failures, duplicate charges, delayed refunds, credit card fraud, foreign exchange losses, tax calculation errors, or any other billing and transaction-related disputes arising from or in connection with the services of the Third-Party Payment Processors. Any and all such disputes must be resolved solely and directly between yourself and the respective Third-Party Payment Processor.

5.3 Refund Rules

(a) Within thirty (30) days of completing your payment, if the Software is completely unable to run due to unresolved technical compatibility issues between the Software and your system, you may contact us (or submit a request through the customer support channels of the Third-Party Payment Processor) to request a refund.

6. Disclaimers & Limitation of Liability

6.1 Provided "As Is"

You expressly understand and agree that your use of the Software Service is at your sole risk. The Software and associated materials are provided on an "AS IS" and "AS AVAILABLE" basis. We disclaim all warranties of any kind, whether express or implied.

6.2 Disclaimer for Data and Work Loss

  • The restriction features, blocking functions, or forced shutdown/logout commands of the Software are not guaranteed to recognize or automatically save the data status of third-party software during execution.
  • Prior to enabling any restriction or focus plan, you must properly save all your work, documents, and data. We shall not be liable for any unsaved data loss, progress corruption, business interruption, work delay, or incidental economic loss caused by the operation of the Software, process terminations, system restrictions, or forced shutdowns.

6.3 Disclaimer for Compatibility and Security Software False Positives

  • We do not warrant that the Software will be fully compatible with all third-party software installed on your device (including but not limited to corporate VPNs, internal networking tools, virtual machines, security software, antivirus programs, and firewalls).
  • Due to the technical mechanism of the Software (such as modifying the Hosts file or intercepting processes), it may be falsely flagged as a high-risk operation by third-party security or antivirus software. The User shall evaluate and bear the risks of any network abnormalities, system lag, third-party software malfunction, or failure of the Service arising from configuration conflicts or third-party security software interference.

6.4 No Guarantee of Effectiveness

Due to ongoing updates of operating systems, browsers, and network protocols, as well as environmental complexity, we do not guarantee that the Software will continuously and without any vulnerability block specific access on all devices or system versions. Users may not claim refunds or compensation from us on the grounds of successfully bypassing or circumventing the restrictions of the Software.

6.5 Corporate and Compliance Environments Disclaimer

If you use the Software in a workplace, educational, or any controlled network/device environment, you must ensure that such use complies with the IT security policies and compliance regulations of your organization or employer. You shall solely bear any liability or penalties resulting from your use of the Software that violates organizational discipline or IT audit compliance requirements.
