Assessed on a remittance basis (income brought into Thailand)

From email to tax report In just three steps

01

Connect email, read-only

Grant access via Nylas OAuth with read-only scope, limited to Dime trade-confirmation emails. Revoke it anytime from your own inbox.

02

Auto-detect and log

The moment a confirmation email arrives, the system reads price, quantity, fees, and date, then records it as a trade — no manual entry.

03

See P&L and taxes owed

Realized P&L via FIFO or Average Cost, plus a personal-income-tax estimate on income remitted into Thailand.

Professional-grade reliability Peace of mind, automated

Skip all manual entry

The moment a Dime confirmation lands, the system reads price, quantity, fees, and date and logs the trade for you — not a single transaction typed by hand.

Secure by design

No direct connection to your brokerage. It only reads trade-confirmation emails, read-only, and never touches or scans your other personal email.

P&L and taxes, computed

Realized P&L via FIFO or Average Cost with precise decimal math, plus a tax estimate on income brought into Thailand.

“Designed to touch as little of your data as necessary — no direct brokerage connection, and it never sees your email password.”

Security design principle Tradebook

Your data, safe Transparent by design

No direct connection to trading apps

Tradebook can’t access your brokerage account and can’t place buy, sell, or transfer orders on your behalf. It only reads confirmation emails you already receive.

Read-only access via OAuth

You never hand Tradebook your email password. Access is read-only and revocable anytime from Gmail or Outlook’s own security settings.

Only trade-confirmation emails

The system processes only Dime trade-confirmation emails — it doesn’t read, scan, or store any of your other personal email.

Nylas
Powered by Nylas Enterprise email API

Tradebook connects to email through Nylas, the email API that global fintech and SaaS companies use for secure email integration — instead of Tradebook storing your email password itself.

  • Encrypted in transit and at rest
  • Fine-grained access via Google / Microsoft OAuth
  • Meets enterprise security standards like SOC 2 Type II and GDPR
  • Revoke the connection anytime, without relying on Tradebook

Questions Answered
