Welcome to Online Tools (formerly referred to as "https://en.udtool.com/"), your go-to platform for simple, practical, and free online tools. We are dedicated to providing a diverse range of utility tools to streamline your daily tasks, including calculation tools (e.g., Screen PPI Calculator, Sphere Surface Area Calculator), photo & color tools (e.g., Image Rotation, Image to Base64), text tools, PDF tools, and development tools (e.g., Gzip Compress/Decompress, Base64 Encode/Decode). Before using any of our tools, we kindly ask you to read and understand the following disclaimers carefully, as your use of this website constitutes your acceptance of these terms.
1. Liability for Malware, Viruses, and Related Damages
While we strive to maintain a secure and safe online environment for all users, Online Tools does not guarantee that the website, its servers, or the tools provided will be completely free from malware, viruses, Trojan horses, or other harmful components. The internet is an open and dynamic space, and despite our regular security checks and updates, we cannot fully eliminate the risk of external threats.
Therefore, we shall not be held liable for any direct, indirect, incidental, consequential, or punitive damages that you may incur as a result of using this website or its tools. This includes, but is not limited to, damages to your computer hardware or software, loss of data, disruption of business operations, or any other financial or non-financial losses caused by the infection of viruses, malware, or other malicious programs accessed through our platform.
We strongly recommend that you take appropriate precautions to protect your devices and data, such as installing and regularly updating reliable antivirus software, enabling firewalls, and avoiding the download or installation of untrusted files.
2. Copyright and Intellectual Property
The algorithms and source codes of the tools available on Online Tools are collected from publicly accessible online resources. Our primary goal is to compile these useful tools in one convenient platform to serve users’ needs, and we have made every reasonable effort to ensure that the use of such materials does not infringe upon the intellectual property rights of any third party.
However, due to the vast and decentralized nature of online information, there may be instances where we inadvertently use content that is protected by copyright or other intellectual property laws without obtaining proper authorization. If you believe that any part of our website (including tool algorithms, source codes, text, images, or other materials) infringes upon your copyright or other intellectual property rights, please contact us immediately with detailed information. This should include:
Your full name and contact information (email address, phone number, etc.).
A clear description of the infringing content and its location on our website (e.g., specific tool page URL).
Proof of your ownership of the intellectual property rights (e.g., copyright registration certificate, original creation records).
Upon receiving a valid and verifiable copyright infringement notice, we will promptly investigate the matter and take appropriate actions, such as removing the infringing content, modifying the relevant tools, or discontinuing the provision of the affected service, to resolve the issue in compliance with applicable laws and regulations.
3. Accuracy and Reliability of Tool Results
The tools on Online Tools are designed to provide users with quick and convenient calculations, conversions, or processing results for reference purposes only. We make every effort to ensure the accuracy and reliability of the tool algorithms, but we do not guarantee the absolute correctness, completeness, or timeliness of the data results generated by the tools.
Several factors may affect the accuracy of the results, including:
Input errors: If you provide incorrect, incomplete, or invalid data when using the tools, the output results will inevitably be inaccurate. Algorithm limitations: Some tools may use simplified algorithms to ensure efficiency, which may lead to minor deviations from precise professional results in specific scenarios.
External variables: For tools related to real-world data (e.g., unit conversions based on regional standards), changes in external standards or parameters may affect result accuracy if not updated in a timely manner.
Therefore, you are solely responsible for verifying and validating the results generated by our tools before using them for any critical purposes (such as business decisions, academic research, engineering design, or legal documentation). Online Tools shall not be liable for any losses or damages arising from your reliance on the unvalidated results of our tools.
4. General Liability for Damages
In addition to the specific disclaimers above, Online Tools shall not be held liable for any direct, indirect, special, incidental, or consequential damages (including but not limited to loss of profits, loss of data, or damage to reputation) that may arise directly or indirectly from:
Your use or inability to use our website or tools.
Errors, omissions, or interruptions in the operation of the website or tools.
Unauthorized access to or modification of your data transmitted through the website.
Any third-party content, products, or services linked to or provided through our website.
This disclaimer shall apply to the fullest extent permitted by applicable law, and it shall survive the termination of your use of our website or any services provided herein.
