Tracking, explained honestly.
This site watches how it gets used — which pages you read, how far you scroll, whether you come back — and adapts to it. Here is exactly what that means, what it will never mean, and the one-click way to turn it off.
What is tracked
- A random ID. Your browser gets an anonymous UUID stored in its own localStorage. It is not derived from anything about you or your device — it's a coin flip, and clearing site data destroys it.
- Your journey on this site. Pages viewed, time on page, scroll depth (in 25% steps), which tools you used, which notes and case studies you read.
- Interest signals. Things like clicking the resume, checking availability, hovering the "book a call" button, or starting the contact form without sending it.
- How you arrived. The referring site and any campaign parameters — this site only ever sees the referrer your browser chooses to send.
- Coarse context. Device class (mobile/desktop), browser language, and your timezone. Your country is guessed locally in your browser from the timezone — your IP address is never read, stored, or sent to any geo service.
From that behavior, the site guesses which of six audiences you belong to — hiring manager, potential client, fellow engineer, learner, recruiter, or just passing through — and adapts a few things (which call-to-action you see, whether a "welcome back" note appears). When it isn't confident, it guesses nothing and shows the default site.
What is never done
- No fingerprinting. No canvas, audio, font, or hardware probing — the ID is random, not derived.
- No cross-site tracking by this system. The behavioral profile described on this page stays first-party and joins no ad network. Separately, when ad campaigns are running, standard ad-measurement tags (Meta/Google) may load — consent-gated in the EU, never for DNT/GPC browsers — as described in the privacy policy.
- No raw IP addresses — not stored, not even looked up.
- No keystroke or session recording. Form fields are never read — only the fact that one was focused.
- No selling or sharing. Ever. The data has exactly one reader (me) and one purpose: making this site better at answering whatever you came for.
Do Not Track is respected
If your browser sends Do Not Track or Global Privacy Control, tracking is off by default — no banner, no nagging. Almost no site honors this; this one does.
Retention & deletion
- Anonymous profiles are deleted automatically after 12 months of inactivity.
- The opt-out button above also purges your profile from the server immediately — it doesn't just stop future tracking.
- Want a copy of your data, or a manual deletion? Email devyuvrajsinh@gmail.com — handled same-day.
Where it lives
In Google Firebase (Firestore), readable only by the site's administrator — enforced by server-side security rules. Your browser can only ever write its own profile (the random ID is the key), and no visitor can read any profile, including their own neighbors'.
