How It Works

透明性のある、仕組み。

How it actually works.

What we touch, what we don't. Which AI runs the show. Where your data lives. We document SekiHQ at spec-sheet depth — this is not a black-box AI product.

From signup to running, in 4 steps

Running in 10 minutes. No complex setup, no annual contracts, no phone calls to cancel.

Draft + send
1

Sign up2 min

Email + password, or one-click with Google. A personal organization is auto-created with you as the owner. Invite teammates later, anytime.

  • 7-day free trial (card required at signup)
  • Cancel before day 7 — never charged
  • Multi-tenant by design: your org's data is fully isolated from others (row-level security)
2

Connect Gmail1 min

One-click OAuth with Google. SekiHQ pulls only subject lines, senders, and timestamps — message bodies are never accessed. Auto-syncs every 5 minutes, automatically building contacts + interaction history from new mail.

  • Read-only scope only (we never request gmail.send)
  • Disconnect anytime — we delete stored tokens immediately
  • Initial sync = last 7 days; ongoing sync = new mail only
3

AI analyzes your relationships~5 min

From the synced metadata, the AI computes warmth scores (0-100), keigo register, and recency per contact. Click "Enrich from emails" on any contact and the AI proposes job title, company, and a relationship summary.

  • Never overwrites your existing values — only fills empty fields
  • Keigo + summary always need your accept / edit / dismiss
  • Powered by an enterprise AI partner — your prompts are never used for model training

いつもお世話になっております。

先日はお忙しい中、お時間をいただきありがとうございました。その後、ご検討いただいた件について、ご状況はいかがでしょうか。

ご都合の良い時にご教示いただけますと幸いです。

引き続き、何卒よろしくお願い申し上げます。

Draft, send, track

Generate keigo-correct draft replies. Review, edit, and send from your normal mail client. SekiHQ logs the send automatically and refreshes the warmth score in real-time. The Ma Timing engine surfaces the right next moment daily.

  • SekiHQ doesn't send mail — you send from your own Gmail / Outlook
  • Sent mail is auto-logged to interaction history
  • Warmth score recomputes in real-time

What we touch / what we don't

In Japanese B2B, data handling is a trust question, not a contract question. Full disclosure.

We do collect
  • Email metadata: subject, From, To, CC, timestamps
  • Contact info: name, company, title, phone, notes — whatever you input or import
  • Interaction summaries: email snippets (first 280 chars), interaction type (sent / received / meeting)
  • Account info: email, hashed password, Google account ID
  • Usage stats: logins, feature use, errors (non-identifying)
We do NOT collect
  • Full email bodies: never accessed, never stored. Snippets are Gmail's own snippet field (first 280 chars)
  • Attachments: never touched
  • Credit card details: handled entirely by Stripe — never stored on our servers
  • Your data for AI training: never sent to any external AI provider for training purposes
  • Third-party ad trackers: zero. No ad cookies. No cross-site tracking.

Security

Encryption in transit

All traffic encrypted with TLS 1.3. HSTS enforces HTTPS at the browser level.

Encryption at rest

Databases and OAuth tokens are stored with enterprise-grade encryption.

Tenant isolation (RLS)

Row-level security (RLS) keeps orgs physically isolated — even on shared tables, your data is invisible to other tenants at the database layer.

Password storage

Passwords are bcrypt-hashed (one-way). Plaintext is never stored, never logged.

Access controls

Three-tier role system inside each org: owner / admin / member. Enterprise plans add SAML SSO and audit logs.

Business continuity

Daily backups, 99.9%+ uptime target, 30-day data-export window after cancellation. Enterprise plans get custom SLA terms.

Our AI commitments

Clear commitments about how SekiHQ uses AI. Specific provider, model names, and contract terms are disclosed under NDA during enterprise engagement.

Used for training
Never — your data is not provided to any AI partner for model training
Data retention
Minimal short-term retention for abuse detection only, then permanently deleted
What's NOT sent
Credit cards, passwords, other users' data, full email bodies
Human in the loop
All AI-generated content is reviewed by you before sending — never auto-sent
Transparency
Sub-processor list disclosed in our Privacy Policy. Architecture details available under NDA for enterprise.
