Privacy Policy

Last updated: August 2026

1. Client-Side Processing Architecture

At ToolNest (https://toolnest.smrityku.workers.dev), user privacy and data security are fundamental core principles. All interactive utilities provided on the website (including JSON formatters, Base64 encoders/decoders, JWT decoders, UUID generators, SQL formatters, password generators, and cryptographic hash generators) execute 100% locally within your web browser using standard Web APIs and client-side JavaScript.

Tool inputs are processed locally in the browser for supported tools and are not intentionally transmitted to ToolNest application servers, stored in remote databases, or shared with third-party networks.

2. Information Collection & Use

We do not collect personal information through our utilities. We collect minimal information only in the following specific contexts:

  • Direct Inquiries & Support: If you choose to contact us via our contact form, we collect the name, email address, topic, and message you submit solely to respond to your technical inquiry or feedback.
  • Hosting Infrastructure & Security Logs: Like most web services, our content delivery network and hosting provider (Cloudflare) automatically logs basic HTTP request metadata (such as IP addresses, approximate geographic region, browser user-agent, and requested asset paths) to defend against distributed denial-of-service (DDoS) attacks, ensure site reliability, and deliver content efficiently. These server logs never contain tool input values or processed payloads.

3. Cookies and Local Storage

ToolNest maintains a strict minimal-storage approach:

  • Theme Preference (localStorage): We store your Dark or Light theme selection in your browser's local storage so your visual preference is remembered across visits. No personal data is stored.
  • Essential Security Cookies: Cloudflare edge nodes may set ephemeral security cookies (e.g. for bot management and DDoS protection) in strict accordance with their privacy standards.

4. Third-Party Infrastructure

ToolNest is delivered using reputable, industry-standard infrastructure:

5. Data Security Best Practices

Because tool data is executed strictly in volatile browser memory, there is no server-side storage or retention of your data. We advise users to maintain up-to-date operating systems, secure browsers, and trusted browser extensions when handling confidential or sensitive production data.
