Privacy Policy

Who we are

Dev Tools Suite (devutilities.net) is a browser-based developer utility suite. There are no user accounts. You can use Local tools without signing in, uploading files to a transform API, or creating a profile.

Summary

Most tools process your input entirely in your browser. A small set of Network tools contact external services and say so in the product UI. Optional history and workflow state stay in this browser’s localStorage. Feedback you choose to send is delivered through our feedback path (not through tool editors).

• •Local tools: payloads are not uploaded for processing.
• •Network tools: WHOIS (RDAP via our edge proxy) and DNS (DNS-over-HTTPS).
• •Storage: localStorage for history, recents, pins, and workflow session state.
• •Feedback: optional message (+ email if you allow contact), protected with Cloudflare Turnstile.
• •Analytics: aggregate site usage via Vercel Analytics — not your pasted tool payloads.

Local tools

The catalog is Local-first. Formatters, converters, validators, generators, AI Agent Builder, MCP Validator, LLM Token Counter, JWT decode, Base64, Hash, and similar tools run in JavaScript in your browser.

For Local tools we do not send your input, output, or intermediate editor contents to our servers for transformation, storage, training, or advertising.

Browser storage (localStorage)

To make the workspace useful across visits, the site may store data only in your browser, including:

• •Recent tools and visit counts
• •Pinned / favorite tools
• •Per-tool editor snapshots or history (where a tool offers it)
• •Active workflow / chain session state
• •UI preferences such as theme or sidebar state (when applicable)

Browser storage — your control

This data never leaves your device unless you copy it elsewhere or a Network tool explicitly sends a limited request (see below). You can clear it anytime with your browser’s site data / localStorage controls, or by using in-app clear actions where a tool provides them. Clearing site data resets history and workflow state for this origin.

Network tools — WHOIS Lookup

WHOIS Lookup is a Network tool. When you look up a domain:

• •Your browser posts the normalized domain to our edge API (/api/whois), which fetches public RDAP JSON from the appropriate registry.
• •DNS-over-HTTPS may resolve hostnames (hostname only) for related records.
• •Optional enrichment (for example SSL or geo on resolved IPs) may call additional edge helpers such as /api/whois/enrich.
• •Responses may be cached for about 15 minutes to reduce load on public registries.
• •A short cooldown applies between lookups to limit abuse.

Network tools — DNS Lookup

DNS Lookup queries Cloudflare DNS-over-HTTPS from the browser. Only the hostname (and query type as needed for the lookup) is sent to that resolver — not unrelated editor payloads from other tools.

How Network tools are labeled

Network tools are marked in the catalog and switch the privacy chrome to network-specific copy. Tool pages include their own disclosure. Subnet Calculator and similar offline math tools are Local even when they appear near Network tools in navigation.

Feedback widget

If you open Feedback, you may submit a category, message, optional email (only if you allow contact), and the page path. Submissions go to /api/feedback.

We use Cloudflare Turnstile to reduce spam. Turnstile runs on the feedback flow — not inside Local tool paste/editor surfaces.

In production, feedback may be emailed to the site operator via Postmark. Rate limits apply. Do not include secrets, production credentials, or highly sensitive personal data in feedback.

Analytics and hosting

The site may use Vercel Analytics for aggregate traffic metrics (for example page views). This is not a transcript of what you paste into Local tools.

The app is hosted on infrastructure that necessarily sees standard web request metadata (IP address, user agent, URL, timestamps) in server and CDN logs for Network/API routes, static assets, and normal HTTP delivery. We do not treat those logs as a product feature for reading your Local tool payloads.

Cookies and third parties

Local tools do not require an account cookie. Third parties that may load in limited contexts include:

• •Cloudflare Turnstile on the feedback dialog
• •Cloudflare DNS-over-HTTPS when you use DNS Lookup
• •Public RDAP registries (via our edge proxy) when you use WHOIS
• •Hosting/CDN and analytics providers that operate the site

What we do not do

We do not require accounts for core tools. We do not place ads inside tool editors. We do not sell your pasted payloads. We do not operate a paywall or billing system for Local tools on this product surface.

International use

The site is available globally via the public web. Network requests (WHOIS, DNS, feedback, hosting) may be processed in regions where our providers operate. Local tool processing remains in your browser.

Changes to this policy

We may update this page when product behavior changes (for example a new Network tool). The “Last updated” date at the top reflects the latest review of this disclosure. Material changes to Network vs Local behavior will be reflected here and in product chrome.

Contact

Questions about this policy can be sent through the feedback form. If you allow contact and include an email, we may reply about that submission. This is not a formal legal intake portal.
