Royal Hacks 2026 · Data Shield

Big Tech tracks you 194 different ways.
We’ll show you 71 of them — site by site — and stop the ones we can.

You never agreed to a cookie banner; you agreed to an iceberg. Second You gives every site a different truth — one you authored — and keeps a three-column receipt for each visit: what’s really you, what we told them, and what they actually got.

01 · Author

One identity, honestly fake.

Name, alias email, birthdate, address, phone, fingerprint seed. You write it once. Every site gets the same consistent alternate — not a fresh lie each visit.

02 · Substitute

The extension lies for you.

Fingerprint overrides, cookie substitution, form-fill. Silent, deterministic, per-site. No pop-up asks for permission every time.

03 · Ledger

See exactly what they got.

A three-column receipt per visit. Real you · Your Second You · what the site actually received — including the things we couldn’t block, and the ones no browser extension ever can.

Our promise

Honesty over cleverness.

Some surfaces a browser extension simply cannot reach — JA4 TLS fingerprints, MitID cryptographic attestation, keystroke-dynamics biometrics, full-DOM session replay. We don’t pretend. Every ledger row carries its own truth — blocked, substituted, leaked, or out of reach— so you always know what we did, what we couldn’t, and why.
