Introduction
DevStackTools ("we," "our," or "us") operates the website at www.devstacktools.com. We are deeply committed to protecting the privacy and security of software developers, engineers, and visitors who utilize our online developer utility tools.
This Privacy Policy outlines how we treat data, how our client-side architecture functions, our use of cookies, and the advertising policies we adhere to in compliance with global data protection standards.
🔒 100% Client-Side Processing Guarantee
Our primary privacy principle is data isolation:
- Zero Data Uploads: Every tool (JSON validator, Base64 encoder, JWT decoder, Bcrypt generator, XML/YAML parser) executes entirely within your browser's JavaScript engine. Your source code, API keys, database records, and payloads are never sent across the network.
- No Server Logs of Input Data: Because no payloads are transmitted to our servers, we have zero access to what you paste or format.
- No User Account Requirement: You can access all tools immediately without creating an account or providing an email address.
Information We Collect
1. Anonymous Analytics
We use privacy-friendly analytics (Vercel Analytics and Vercel Speed Insights) to monitor site performance, page load times, and aggregated visitor metrics (such as browser type and approximate country). These analytics do not track individual identities or use persistent tracking cookies.
2. Local Browser Storage
We utilize your browser's localStorage strictly to store your personal UI preferences (such as Light/Dark theme mode and your saved favorite tools list). This data never leaves your device.
Google AdSense & Advertising Disclosures
To support the continuous development and hosting of our free developer utilities, we partner with third-party advertising networks, including Google AdSense.
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites on the internet.
- Google's use of advertising cookies (including the DoubleClick DART cookie) enables it and its partners to serve ads to our users based on their visit to our sites and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings.
- Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting www.aboutads.info or the Network Advertising Initiative at optout.networkadvertising.org.
Your Privacy Rights (GDPR & CCPA / CPRA)
Under data protection regulations including the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), you have specific rights regarding your personal information:
- Right to Know & Access: The right to request information on any data collected.
- Right to Deletion: You can clear your local browser storage at any time via your browser settings.
- Right to Opt-Out of Sale: We do NOT sell, rent, or trade any personal information.
- Non-Discrimination: You will never receive degraded service for exercising your privacy rights.
