Privacy

The short version: this site collects almost nothing, and the tools collect literally nothing.

The 124 tools never see your data

Every tool on /tools/ runs entirely in your browser. The JSON you format, the JWTs you decode, the passwords you generate — none of it is sent anywhere, logged, or stored. You can verify this: open your browser's network tab while using any tool. Four tools make narrow network calls to do their job (DNS lookups via Cloudflare, certificate checks via crt.sh, and the response-time tester calling the URL you provide) — those calls carry only the query itself, never anything else.

Cookies & advertising measurement

The site itself works entirely without cookies; tools save your own preferences (like favorites) in your browser's localStorage, which never leaves your device. When I run ad campaigns, standard advertising tags (Meta, Google) may load to measure whether those ads actually led to an enquiry — never for EU visitors without explicit consent (you'll see a plain accept/decline choice, and "decline" is respected), and never for anyone sending Do Not Track / Global Privacy Control. These tags measure conversions on this site; I don't run third-party ad inventory, sell data, or do fingerprinting.

Analytics

Page views are counted with Plausible, a cookieless, GDPR-compliant analytics service that stores no personal data and cannot identify you. It records aggregate counts (page, country, browser family) — nothing individual.

How you use this site (first-party, opt-out-able)

The site also keeps its own anonymous record of how it gets used — pages read, scroll depth, tools tried, return visits — under a random ID in your browser, so it can adapt to what you're here for (an engineer, a client, and a learner want different things). This is first-party only: no cross-site tracking, no fingerprinting, nothing sold or shared. It includes a once-per-session geo-IP lookup (IP + approximate city-level location) described on the tracking page. Browsers sending Do Not Track / Global Privacy Control are excluded by default, and one click deletes your profile from the server: the full honest breakdown and the opt-out switch live at /privacy/tracking/.

What is stored, and only when you submit it

• Contact / demo requests: the name, email, and message you type into the contact form — stored so I can reply, plus an instant notification to me. Ask and it's deleted.
• Newsletter: your email address, only if you subscribe. Every digest includes an unsubscribe path; one email to devyuvrajsinh@gmail.com removes you instantly.
• Testimonials: what you write on an invite link, published only after review and only as you wrote it.
• Tool suggestions: the suggestion text itself.

All of this lives in Google Firebase (Firestore) in the asia-south1 (Mumbai) region, readable only by the site's single administrator — enforced by server-side security rules, not just interface design.

Third-party services

• Firebase Hosting / Firestore (Google) — serves the site and stores form submissions.
• Plausible — cookieless page-view counts.
• cal.com — only if you choose to book a call there.
• Ad measurement tags (Meta Pixel, Google tag — only while campaigns run) — consent-gated in the EU, disabled for DNT/GPC browsers, used solely to attribute enquiries to ads. Any email sent server-side for conversion matching is SHA-256 hashed first.

Questions or deletion requests

Email devyuvrajsinh@gmail.com — I'm the only person who reads it, and deletion requests are honored same-day.
