Privacy Policy

Plain-language explanation of how OneDevToolkit handles information — built around browser-side processing.

Last updated: August 6, 2026

Summary

  • 300+ tools process your text and files in your browser. We do not upload tool inputs to OneDevToolkit servers for processing.
  • No account is required to use the core toolkit. Optional sign-in syncs favourites and recent tools — not file contents.
  • We use privacy-conscious analytics (Google Tag Manager and GA4) to understand traffic — not what you paste into tools.
  • Contact form messages are emailed to our team and protected with Google reCAPTCHA. We do not currently operate an email newsletter.

1. Who we are

OneDevToolkit (onedevtoolkit.com) provides free online developer utilities — JSON formatters, token counters, PDF tools, image compressors, and more. This policy describes how we handle information when you visit the site, use our tools, create an account, or contact us.

2. Information we do not collect from tools

Our tools are designed to run locally in your browser using client-side JavaScript and standard Web APIs. When you format JSON, test a regex, compress an image, or work with a PDF, that content stays on your device.

We do not transmit, store, or log:

  • Text, code, or payloads you enter into tools
  • Files you open for client-side processing (PDFs, images, video where supported in-browser)
  • Passwords, API keys, tokens, or other secrets you paste into utilities
  • Output generated by tools in your browser

If a specific tool must contact an external service (for example, fetching a public URL you provide), that behaviour is limited to what you explicitly request. Tool descriptions on the site explain when network access is involved.

3. Information we may collect

3.1 Contact form

When you submit our contact form, we receive the details you choose to provide — typically your name, email address, subject, optional tool name, and message text. We use this information solely to respond to your enquiry, troubleshoot issues, or follow up on feedback.

Submissions are processed through a Netlify serverless function and delivered by email via our SMTP provider (Mailgun). Google reCAPTCHA v3 helps block spam; Google may process technical signals as part of that check. See Google’s Privacy Policy for details.

3.2 Optional accounts

You can use most of OneDevToolkit without registering. If you create an account, we may store:

  • Email address and a hashed password
  • Favourite tools and recently used tool slugs (identifiers only — not file or text content)
  • Basic account metadata such as creation date

Vault entries, recipe workflows, and similar workspace data are stored in your browser (localStorage or IndexedDB) by default. Passphrase-encrypted vault data remains on your device unless a future sync feature is explicitly enabled and described at that time.

3.3 Analytics and tag management

We use Google Tag Manager (container GTM-NKS29HFG) and Google Analytics 4 (measurement ID G-6PRCK6PN01) to understand how visitors use the site — for example which pages are viewed, approximate geography, browser type, and referral source.

This analytics data is aggregated and does not include the contents of tools you use. You can limit analytics through browser settings, opt-out extensions, or Google’s Analytics Opt-out Browser Add-on.

3.4 Hosting and server logs

OneDevToolkit is hosted on Netlify. Like most hosting platforms, Netlify may retain standard server logs (IP address, request time, user-agent, referring URL) for security, abuse prevention, and operational reliability. These logs are governed by Netlify’s Privacy Policy.

3.5 Newsletter

We do not currently offer an email newsletter or marketing mailing list. If we introduce one in the future, we will update this policy and ask for your consent before sending promotional messages.

4. How we use information

We use the limited information described above to:

  • Operate, maintain, and improve OneDevToolkit
  • Respond to contact form submissions and support requests
  • Authenticate optional accounts and sync favourites
  • Measure site performance and fix bugs
  • Protect the service against spam, abuse, and security threats
  • Comply with applicable legal obligations

We do not sell your personal information. We do not use tool inputs for advertising profiling.

5. Cookies, local storage, and similar technologies

OneDevToolkit uses browser storage to keep the site usable and respectful of your preferences:

  • Theme preference — stored locally so dark/light mode persists
  • Favourites and recent tools — stored locally; optional account sync covers slugs only
  • Vault, recipes, and workbench data — stored locally in your browser unless otherwise stated
  • Analytics cookies — set by Google Tag Manager / GA4 as described above
  • reCAPTCHA — may set cookies or use similar storage when you submit the contact form

For a focused breakdown, see our Cookies & Storage page. You can clear site data through your browser settings at any time.

6. Third-party services and libraries

Beyond analytics and spam protection, OneDevToolkit relies on third parties that may process limited technical data when you use the site:

  • Netlify — hosting and serverless functions (contact form)
  • Mailgun — email delivery for contact messages
  • Google — Tag Manager, Analytics, reCAPTCHA, and font delivery where loaded
  • jsDelivr / CDN providers — delivery of open-source libraries (jQuery, PDF.js, FFmpeg.wasm, and others)

Some tools load open-source engines entirely in your browser. Those projects remain under their own licenses; see Attributions. We do not claim ownership of third-party software.

External documentation links (for example MDN or API provider sites) are outside our control. Review their privacy practices separately.

7. Data storage and security

We apply reasonable technical and organisational measures to protect information we handle — HTTPS everywhere, hashed passwords for accounts, and minimal server-side data collection by design.

Tool processing intentionally avoids our servers, which reduces exposure of sensitive content. No method of transmission or storage is perfectly secure; we cannot guarantee absolute security, but we work to keep risk proportionate to the data we hold.

Contact form emails are retained only as long as needed to resolve your request, unless we must keep a record for legal or abuse-prevention reasons.

8. Your rights and choices

Depending on where you live, you may have rights to access, correct, delete, or restrict certain personal information we hold — for example contact form correspondence or account details.

Practical steps you can take today:

  • Clear browser storage — removes local vault, recipe, and preference data on your device
  • Disable analytics — via browser settings, extensions, or Google’s opt-out tools
  • Delete your account — contact us if account deletion is not yet available in the UI
  • Opt out of reCAPTCHA — avoid submitting the contact form, or email us directly at support@onedevtoolkit.com

To exercise privacy rights or ask questions about data we hold, contact us using the details below. We will respond within a reasonable timeframe.

9. Children’s privacy

OneDevToolkit is aimed at developers, technical professionals, and general adult users. We do not knowingly collect personal information from children under 13 (or the applicable age in your jurisdiction). If you believe a child has provided us personal data, please contact us and we will take steps to delete it.

10. International visitors

OneDevToolkit is operated from the United States perspective of our hosting providers. If you access the site from another country, your information may be processed in the United States or other locations where our service providers operate. By using the site, you understand that data may cross borders with appropriate safeguards where required by law.

11. Changes to this policy

We may update this Privacy Policy when we add features, change providers, or adjust legal requirements. When we make material changes, we will revise the “Last updated” date at the top of this page. Continued use of OneDevToolkit after an update means you accept the revised policy.
