Who we are

Our website address is: and our second brain hub address is


When visitors leave comments on the site we collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection.

An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy is available here: After approval of your comment, your profile picture is visible to the public in the context of your comment.


If you upload images to the website, you should avoid uploading images with embedded location data (EXIF GPS) included. Visitors to the website can download and extract any location data from images on the website.


If you leave a comment on our site you may opt-in to saving your name, email address and website in cookies. These are for your convenience so that you do not have to fill in your details again when you leave another comment. These cookies will last for one year.

If you visit our login page, we will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

When you log in, we will also set up several cookies to save your login information and your screen display choices. Login cookies last for two days, and screen options cookies last for a year. If you select “Remember Me”, your login will persist for two weeks. If you log out of your account, the login cookies will be removed.

If you edit or publish an article, an additional cookie will be saved in your browser. This cookie includes no personal data and simply indicates the post ID of the article you just edited. It expires after 1 day.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.

Who we share your data with

If you request a password reset, your IP address will be included in the reset email.

How long we retain your data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue.

For users that register on our website (if any), we also store the personal information they provide in their user profile. All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

What rights you have over your data

If you have an account on this site, or have left comments, you can request to receive an exported file of the personal data we hold about you, including any data you have provided to us. You can also request that we erase any personal data we hold about you. This does not include any data we are obliged to keep for administrative, legal, or security purposes.

Where your data is sent

Visitor comments may be checked through an automated spam detection service.

Rules for Instructor

Selected or invited instructors are permitted to create their own second brain content including online courses and promote them to their students free of charge while other registered instructors can create their own second brain content based on monthly subscription fee. Authorised instructors may also utilize this platform to register and record the completion status for in-person or real-time courses. However, all course materials must be lawful and must not contain any content that is prohibited by local law. In addition, course materials must not infringe on any copyrights. If allegations of such infringements are received or discovered during inspections, and upon confirmation, the infringing course materials will be removed without further notice. Moreover, the instructor’s status may be revoked.

Rules for Student

Students have the option to browse free courses. Please note, however, that a student’s personal learning records will be stored on the online platform. After making a payment, students can access paid courses. Payment information is held by the corresponding mobile payment institution. Our site merely serves as an intermediary and does not store any personal payment information of students.
