Matching Architecture

Four-pass matching pipeline. Each pass adds confidence scoring. Higher-confidence methods override lower ones.

PASS 1
Synonym Match
Exact + normalized match against 200+ synonym dictionary
→
PASS 2
Heuristic Match
Word overlap analysis across all field text signals
→
PASS 3
Type Match
HTML input type (email → email, tel → phone)
→
PASS 4
Autocomplete
HTML autocomplete attribute (given-name, postal-code, etc.)

Field Signature Extraction

For each fillable input, the extension extracts 8 signals:

name — field name attribute
id — field id attribute
type — input type (text/email/tel/date)
placeholder — placeholder text
aria-label — accessibility label
labelText — extracted from <label>, table, spans
autocomplete — HTML5 autocomplete hint
sectionHeading — nearest h1-h6 or legend

Label Detection Methods

Six methods tested and validated:

✓ <label for="id"> — explicit label
✓ <label><input></label> — wrapping label
✓ aria-label — accessibility attribute
✓ Table cell — <td>Label</td><td><input>
✓ Span sibling — <span>Label</span><input>
✓ Placeholder-only — no visible label

Security Model

Zero-trust local architecture. No data ever leaves the device.

🔐

AES-256-GCM Encryption

Profile data encrypted at rest using AES-256-GCM with PBKDF2 key derivation (600,000 iterations). Each encryption uses a unique random IV.

🚫

Zero Network Calls

No server communication whatsoever. No analytics, no telemetry, no API calls. All logic runs locally in the browser.

🔒

Minimal Permissions

Uses activeTab only — the extension can only access the current tab when explicitly activated by the user.

🛑

Never Auto-Submits

ApplyOnce fills fields but NEVER submits forms. The user always reviews and clicks submit themselves.

📊

Confidence Scoring

Every field fill includes a confidence score. Low-confidence fills are flagged visually so users can verify before submitting.

📤

Full Data Export

Users can export their complete profile as JSON at any time. No vendor lock-in. Delete all data with one click.
