Privacy Policy

Last updated: 2026-04-23

TL;DR: If you subscribe to the Daily Options Report, we collect your email address and a language preference. We email you the report each weekday. We never sell, rent, or share your address. You can unsubscribe any time by replying unsubscribe to any email.

Who we are

DappGo is a personal project operated by Yan Long Lai. You can reach us at laiyanlong@gmail.com.

What we collect and why

Email subscription (Daily Options Report)

Your email address — so we can send you the daily report
Language preference (zh or en) — so we send the report in your preferred language
The date you subscribed — so we can measure growth and honor data-retention requests

Your address is transmitted via FormSubmit.co (which delivers the form submission to our Gmail inbox) and stored in a private code repository as a plain text file. We do not use any third-party marketing tools, analytics pixels in emails, or open/click tracking.

Contact form

If you use the contact form on the home page, the data you submit (name, email, company, message) is sent to our Gmail via FormSubmit.co and kept only for the purpose of replying to you.

Website analytics

The website uses Google Analytics (via gtag.js) to measure page views and referrer traffic. Google Analytics stores cookies in your browser. If you prefer not to be tracked, you can install a blocker such as uBlock Origin or use your browser's Do Not Track setting.

How we use your data

To deliver the Daily Options Report you signed up for
To respond to messages you send us via the contact form
To compute aggregate subscriber counts (e.g., "247 subscribers this month") — never per-user behavior

We do not, and will not:

Sell, rent, or trade your email address
Send you unrelated marketing emails
Add you to other lists without your consent
Use your data to train machine-learning models

How long we keep it

Your subscription record is kept as long as you remain subscribed. When you unsubscribe, your address is removed from the list within one hour (and no later than the next daily run).

Contact form messages are kept in Gmail for reply history. You can request deletion by emailing us.

Your rights

You can, at any time:

Unsubscribe by replying unsubscribe to any daily email, or by emailing laiyanlong@gmail.com with the subject "Unsubscribe"
Request a copy of the data we hold on you — email us and we'll reply within 7 days
Request deletion of all your data — we'll process within 7 days
Change your language preference — email us or re-subscribe with the preferred setting

Security

Subscriber emails are stored in a private GitHub repository and accessed only by the author. Email delivery uses Gmail's SMTP with TLS. No data is stored on our own servers.

Children

The service is not directed to children under 13. We do not knowingly collect data from them.

Changes to this policy

Material changes will be announced on this page and, for subscribers, in the email digest. The "Last updated" date at the top of this page reflects the most recent version.
