How your data is handled on this website. Last updated May 2026.
This website (hammadhaqqani.com) is a personal portfolio and blog operated by Hammad Haqqani. Your privacy matters. This policy explains what data is collected, how it's used, and your rights. The short version: I collect as little as possible, I never sell your data, and all 86 tools on this site run entirely in your browser, with one transparent exception (the Weather Widget queries the public Open-Meteo API; details below).
85 of the 86 free AI and DevOps tools on the /tools page run 100% client-side in your browser using JavaScript, Web Crypto API, and other browser APIs. The single exception is the Weather Widget, described below. The 85 client-side tools include: • AI & LLM Tools (40): Claude Code ROI calculator, CLAUDE.md generator, Claude Code hooks builder, MCP server config builder, OpenAI to Anthropic SDK migrator, tokenizer comparator, AI agent loop cost predictor, AI agent cost calculator, system prompt analyzer, vibe coding prompt generator, prompt injection scanner, fine-tuning formatter, context window visualizer, LLM parameter guide, AI output parser, prompt comparator, token counter, AI model comparison, system prompt builder, AI API request generator, JSON schema generator, AI content detector, pricing calculator, image prompt builder, prompt templates, AI resume builder, meeting summarizer, AI tone rewriter, i18n scaffold generator, AI data extractor, AI code reviewer, git commit & PR writer, AI regex builder, API docs generator, AI SQL assistant, document Q&A, automation recipe builder, AI log analyzer, prompt eval suite, AI diagram generator • SEO & Web Tools (5): Meta tag generator, social card preview, robots.txt generator, color contrast checker, privacy policy generator • Data Converters (10): JSON/YAML converter, JSON formatter, YAML validator, JSON to TypeScript, CSV/JSON converter, Base64 encoder/decoder, URL encoder, code formatter, SVG to JSX converter, HTML to Markdown converter • DevOps & CI/CD Tools (13): Cron builder, cron to English translator, Docker to Compose converter, subnet calculator, chmod calculator, HTTP status codes, diff checker, regex tester, .gitignore generator, SQL formatter, Postgres index recommender, NAT Gateway cost calculator, GitHub Actions cost calculator • Security Tools (4): JWT decoder, hash generator (SHA-256/384/512), UUID/ULID generator, password generator • Text & Data Tools (6): Timestamp converter, string utilities, Markdown previewer, README generator, mock data generator, JSON visualizer • CSS & Design Tools (4): CSS gradient generator, box shadow generator, color palette generator, flexbox playground • Image & Media Tools (3): QR code generator, image compressor, code screenshot generator NO data from these 85 client-side tools is ever transmitted to any server I control. All processing for those tools happens locally in your browser. I have no access to any text, code, passwords, API keys, prompts, or other sensitive information you use in them. One exception: the Weather Widget queries the public Open-Meteo API (open-meteo.com) for current conditions, forecasts, and air quality. When you search for a city, the city name plus the resolved latitude and longitude are sent to Open-Meteo's servers. Open-Meteo is a free, privacy-focused weather service that does not require an API key, does not log user identifiers, and does not track individual users. See open-meteo.com/en/terms for their terms.
