By accessing or using onlinedevtools.app ("Site"), you agree to be bound by these Terms and Conditions. If you do not agree, you must discontinue use immediately. Eligibility:
You must be at least 18 years old or the age of majority in your jurisdiction to use this Site. By using the Site, you represent that you meet this requirement. License to Use:
A limited, non-exclusive, non-transferable, revocable license is granted to access and use the Site for lawful purposes only.
- No malicious, abusive, or unlawful use.
- No automated scraping or abusive traffic.
- No reverse engineering or exploitation attempts.
- No interference with performance, security, or infrastructure.
Violations may result in termination of access without notice. Tool Output Disclaimer:
Tools generate results based on user input. Accuracy, completeness, or fitness for a particular purpose is not guaranteed. Users are solely responsible for validating outputs before reliance.
The Site does not provide legal, financial, compliance, security, or professional advice. Data and Availability:
The Site operates primarily in-browser. No guarantee is made regarding uptime, continuity, or data retention. Browser storage may be cleared at any time. The Site is not responsible for loss of data, configurations, or session information. Advertising and Third Parties:
Advertising may be displayed to support hosting and development. Ads are served by third-party providers. The Site is not responsible for third-party content, claims, or external services. Use of third-party links is at your own risk. Intellectual Property:
Site content, design, branding, and original code are the property of Online Dev Tools unless otherwise stated. No reproduction, redistribution, or commercial exploitation is permitted without written permission. Disclaimer of Warranties:
The Site is provided "as is" and "as available." No warranties, express or implied, are made regarding reliability, availability, security, or fitness for a particular purpose. Limitation of Liability:
To the fullest extent permitted by law, Online Dev Tools shall not be liable for direct, indirect, incidental, consequential, or special damages, including loss of data, revenue, or business interruption.
Total liability, if any, shall not exceed $100 USD. Indemnification:
You agree to indemnify and hold harmless Online Dev Tools from any claims, damages, liabilities, or expenses arising from misuse of the Site, violation of these Terms, or reliance on tool outputs. Governing Law:
These Terms are governed by and construed in accordance with the laws of the United States and the state in which the Site's operator is established, without regard to conflict-of-law principles. Where the mandatory consumer-protection laws of your own country or state of residence apply, nothing in these Terms removes the protections those laws give you. Modifications:
These Terms may be updated at any time. Continued use of the Site constitutes acceptance of revised Terms. How tools work and what they cannot guarantee
Every tool on this site is designed to run locally in your browser. When you paste a JWT, a JSON payload, an IP address, or a CSP header into any tool on this site, that input is processed by JavaScript running on your own machine. It is not transmitted to any server operated by Online Dev Tools. This is a deliberate architectural choice, not just a privacy claim — the site has no backend application server that receives your tool inputs.
This architecture means that tool output depends entirely on your browser's JavaScript engine and the correctness of the client-side code. Tool outputs are provided for informational and development purposes only. They are not a substitute for verification in your actual runtime environment. A JWT decoded here shows you what the token contains; it does not tell you whether your server's validation logic will accept it. A CSP policy analyzed here shows you structural issues and common misconfigurations; it does not certify that your deployment is secure. You are responsible for verifying that tool output is appropriate for your specific use case before acting on it.
Third-party tools and external requests
Some tools — specifically WHOIS Lookup, IP Lookup, and Hostname to IP — make network requests as part of their function. These requests go to third-party APIs (RDAP registries, the Google DNS-over-HTTPS API, and IP intelligence APIs) and are necessary for the tool to work. Input you provide to these tools may be transmitted to those third parties as part of the lookup. The site does not control those third-party services and is not responsible for how they handle query data. Their respective privacy policies and terms apply.
