1. Introduction & Ownership
CruxDev (“we”, “our”, “us”), accessible at cruxdev.tech, is an independent open developer utility suite and prompt library created, operated, and maintained by Cholaraja R P in an individual creator capacity based in Karnataka, India. We are committed to absolute data privacy and transparency. This policy explains how our web application functions and details our zero-server privacy architecture.
2. Zero Server-Side Data Collection
CruxDev operates under a strict client-side model. When you use any of our 300+ developer utilities (including JSON formatters, JWT decoders, base64 encoders, cryptography tools, regex testers, code converters, CSS studios, image optimizers, and PDF tools):
- Local Browser Execution: All calculations, encodings, cryptographic transformations, and formatting operations execute locally in your browser using standard Web APIs, Web Cryptography, Canvas APIs, and WebAssembly.
- No Remote Data Transmission: Your input data, confidential code snippets, authentication tokens, API keys, JSON payloads, and uploaded documents are never transmitted to, inspected by, or stored on any server operated by CruxDev.
- No User Accounts: CruxDev does not require registration, login, email authentication, or account creation to access any tool, prompt, or feature.
3. Voluntary Developer Tips (Buy Me a Coffee)
CruxDev is completely free to use. Users who choose to support developer hosting and ongoing maintenance may optionally send a voluntary gratuity (“Tip Dev” / “Tip the Developer”):
- Zero Financial Data Stored: CruxDev does not collect, process, handle, or store credit card numbers, debit card numbers, bank account details, or billing addresses.
- External Payment Handling: All voluntary tips are processed externally by Buy Me a Coffee (Publisherr Inc.) on buymeacoffee.com, under the Buy Me a Coffee Privacy Policy.
- No Required Transactions: Tipping is strictly voluntary. All tools, prompts, and calculators remain unrestricted and free to all users.
4. Local Storage & Cookies
We use browser local storage (localStorage) exclusively for client-side user preferences:
- Theme & Layout: Saving dark or light mode preferences and sidebar state.
- History & Bookmarks: Storing recently used utilities and bookmarked items locally on your device for fast access.
- Learning Progress: Tracking recently used tools and bookmarked items locally on your device.
This data remains exclusively on your device and can be removed at any time by clearing your browser cache or site data.
5. Advertising & Third-Party Cookies (Google AdSense)
CruxDev is supported by non-intrusive advertising served through Google AdSense.
