CTD handles sensitive relationship data. Here's a precise account of what we collect, what we don't, and why each decision was made.

What CTD reads from your email

By default, CTD reads only email metadata — not the body of your emails. Specifically:

  • From, To, CC, BCC — who you communicated with
  • Date and time — when you communicated
  • Subject line — used to understand communication context at a high level

This is everything CTD needs to build your relationship graph, score your connections, and surface warm intro paths.

We do not read or store email bodies by default. The content of what you write to people is never accessed or retained.

Optional: email body access (Read-only scope)

You can optionally grant CTD read access to email bodies. If you do:

  • Signature processing — CTD parses email signatures to automatically extract contact details: phone numbers, Calendly links, job titles, and other information people include in their signatures. This enriches contact profiles without any manual data entry.
  • You'll be able to read your own email threads directly within CTD when looking at a contact
  • CTD never stores email bodies — they are fetched on demand and displayed only to you
  • Email bodies are never retrieved without a specific action on your part
  • This access is used solely to surface emails for a better experience — nothing else

You can revoke this access at any time from CTD's settings or directly from your Google or Microsoft account.

What CTD does not access

  • Email body content (unless you explicitly grant optional access)
  • Email attachments
  • Calendar event details or meeting notes
  • Slack, Teams, or any other messaging platform
  • Your passwords — CTD connects via OAuth only

LinkedIn connections

You can optionally import your LinkedIn connections via a CSV export from LinkedIn. CTD stores only names, companies, and roles from this export — no messages, no activity data, no other LinkedIn information.

How relationship scores are calculated

CTD calculates relationship strength scores using only email metadata signals: frequency of contact, recency, and whether communication is bidirectional. No AI reads your email content to infer sentiment or intent.
