Feature deep-dive
We never read your email.
Every other product that claims to protect your inbox does so by reading it. Glance does not. We work from headers and metadata only — and for the small fraction of emails that need deeper analysis, the ML model runs on your device, not ours.
What Glance sees. What it never touches.
What we scan
Sender email address
To check against allowlist, blocklist, and reputation.
Sender domain
Domain age, registration history, homoglyph detection.
SPF / DKIM / DMARC records
Authentication signals: is this sender who they claim to be?
Email headers
Routing path, relay hops, X-headers for spoofing signals.
Link domains (not content)
We check if linked domains are on threat intel lists.
What we never touch
Email subject line
Not stored. Not sent to any server.
Email body text
Processed in-memory only if Tier 4 ML is triggered. Immediately discarded.
Email attachments
Not accessed.
Your contacts list
Not accessed.
Previous emails
Historical content is never accessed.
4 tiers of detection. 0 reads of your content.
Each tier runs in sequence. Most emails are resolved in milliseconds at Tier 1 or 2. Only grey-area emails reach Tier 4 — and even then, the model runs on your device.
Tier 1
Allowlist / Blocklist
<1ms
Instant check — does this sender appear on your approved or blocked list?
Tier 2
Heuristics
<100ms
SPF / DKIM / DMARC validation, domain age, homoglyph detection, redirect chain analysis.
Tier 3
Threat Intelligence
<300ms
Cross-referenced against VirusTotal, AbuseIPDB, Google Safe Browsing, Spamhaus, and OpenPhish.
Tier 4
ML Analysis (grey area only)
<50ms
LightGBM ONNX model — runs locally on device, never on our server. F1: 0.9919. Triggered for borderline cases (score 20–80) only.
Why this matters for seniors.
Email is private. It should stay that way.
Medical questions, financial decisions, conversations with doctors and lawyers — seniors use email for sensitive matters. A security product that reads those emails to protect them is not protecting them.
Trust is the product.
Your parent is trusting Glance to protect them. That trust should not require handing over their private correspondence. Zero-knowledge means we have earned protection another way.
Family should not need to read it either.
Companions see sender metadata — not the email content. Your parent's dignity is preserved. You make approval decisions based on who is sending, not what they wrote.
Protection that respects privacy.
No emails read. No bodies stored. Full protection.
