Legal

Terms and conditions

These terms explain the rules for using ToolBarKit and the limits of the tools we provide. Please read them before using the service.

Effective date: September 27, 2026

The short version

Use the tools lawfully, do not harm the service or other people, keep copies of anything important, and independently check results before relying on them. Health results are informational, and decoding a JWT does not verify that it is genuine.

1. Acceptance of these terms

By accessing or using ToolBarKit, you agree to these terms and our Privacy Protection policy. If you do not agree, do not use the service. If you use ToolBarKit for an organization, you confirm that you are authorized to accept these terms for that organization.

You must be legally able to agree to these terms. If local law requires permission from a parent or guardian, you may use the service only with that permission.

2. The service

ToolBarKit is a collection of general-purpose utilities, including notes, short links, text counters and formatters, Base64 tools, a JWT decoder, and health-related calculators. Features may process data in your browser, send data to the ToolBarKit backend for a result, or store data when the feature is designed to save it.

The service is provided without a guaranteed service level. We may add, change, suspend, or discontinue a feature when reasonably necessary. When practical, we will avoid changes that unnecessarily interfere with saved content.

3. Your responsibilities

You are responsible for:

  • the information and content you submit;
  • checking inputs and outputs before relying on them;
  • keeping independent copies of important notes, links, or results;
  • protecting note keys, passwords, tokens, and other confidential information; and
  • complying with laws and third-party rights that apply to you.

Note keys, usernames, and short-link keys are identifiers, not a guarantee of secrecy. Use the available password protection for notes where appropriate, and do not treat an unprotected or shared note as confidential.

4. Acceptable use

You must not use ToolBarKit to:

  • break the law or infringe another person's rights;
  • create, store, or distribute malware, phishing content, unlawful material, or links intended to deceive or harm;
  • collect, expose, or misuse personal or confidential information without authorization;
  • bypass access controls, probe systems without permission, or attempt to gain unauthorized access;
  • overload, disrupt, scrape, or automate requests in a way that harms the service or prevents others from using it; or
  • misrepresent your relationship with ToolBarKit or its operators.

This section does not prevent you from using your browser's Network panel to follow our documented JWT privacy-verification steps.

5. Your content and limited permission

You keep ownership of content you submit. You confirm that you have the rights and permissions needed to submit it and allow us to process it as described here.

For content stored by a ToolBarKit feature, you grant ToolBarKit a limited, non-exclusive permission to host, copy, process, and deliver that content only as needed to operate, secure, and support the feature. This permission ends when the content is deleted, except for temporary backups, security records, or retention required by law.

We may remove or restrict content when reasonably necessary to address unlawful use, security risk, infringement, abuse, or a valid legal request.

6. Tool-specific limitations

Health tools

BMI, waist-ratio, calorie, and related results are estimates for general information. They are not medical advice, diagnosis, or treatment and are not a substitute for a qualified health professional. Do not use them for an emergency.

JWT decoder

The decoder displays a token's header and payload locally in your browser. It does not verify the signature, issuer, expiry, audience, claims, safety, or authenticity. A decoded token must not be treated as a validated token.

Short links

Short links redirect to destinations chosen by users. We do not endorse or control those destinations. Check a destination before opening or sharing it.

Other utilities

Formatter, counter, Base64, and similar outputs can contain errors or differ from another tool's conventions. Verify outputs before using them in production, security, financial, legal, or other important work.

7. Privacy and security

Our Privacy Protection policy explains how different features handle information. You are responsible for deciding whether ToolBarKit is suitable for the information you enter. Do not submit secrets, regulated data, or highly sensitive personal information unless you understand the feature's handling and have authority to do so.

We use reasonable safeguards, but no website, network, or storage system is completely secure. Please report a suspected vulnerability responsibly and do not exploit it.

8. Third-party services and links

ToolBarKit relies on third-party infrastructure and may link or redirect to third-party websites. Their services, availability, security, content, and terms are outside our control. Your use of a third-party service is governed by that provider's terms and privacy practices.

9. Intellectual property

ToolBarKit's name, interface, original content, and service design are owned by their respective operators or licensors. These terms do not transfer those rights to you. Any source code made available in a repository remains governed by the license included with that code.

Feedback is voluntary. You allow us to use feedback without payment or obligation, while we will not claim ownership of your underlying content merely because it appears in the feedback.

10. Availability and enforcement

We may limit or block access when reasonably necessary to protect the service, comply with law, address abuse, or enforce these terms. Where appropriate and practical, we may provide notice or an opportunity to correct the issue.

You may stop using ToolBarKit at any time. Provisions that reasonably need to survive—such as ownership, disclaimers, and limits of liability—continue after use ends.

11. Disclaimers

ToolBarKit is provided on an “as is” and “as available” basis. To the extent permitted by applicable law, we do not promise that the service will always be available, uninterrupted, secure, or error-free, or that any result will be complete or suitable for a particular purpose.

Nothing in these terms excludes warranties or rights that cannot lawfully be excluded under the laws that apply to you.

12. Limitation of liability

To the extent permitted by applicable law, ToolBarKit and its operators will not be liable for indirect, incidental, special, consequential, or exemplary loss arising from use of—or inability to use—the service, including loss of data, opportunity, revenue, or goodwill.

These limitations do not apply where liability cannot legally be limited, including any liability that applicable law requires us to retain. Your statutory consumer rights are not affected.

13. Applicable law and disputes

These terms are governed by applicable law. Mandatory protections and rights available in your place of residence continue to apply. Before starting formal proceedings, please contact us so we can try to resolve the concern informally. A court or authority with lawful jurisdiction may hear any dispute that cannot be resolved.

14. Changes to these terms

We may update these terms to reflect feature, legal, security, or operational changes. The effective date at the top identifies the current version. If a change is material, we will take reasonable steps to make it visible. Continued use after updated terms take effect means you accept them, where permitted by law.

15. General terms and contact

If part of these terms is found unenforceable, the remaining terms will continue to apply to the extent allowed by law. A delay in enforcing a term is not a waiver of it. These terms and the linked Privacy Protection policy form the agreement about your use of ToolBarKit.
