About

Mission

daynentang.com helps every family and every person learn four foundations for free: skills, character, mind and body. Each lesson is based on evidence and can be used right away, even with no money and no teacher.

Vision: every Vietnamese family, however poor or far away, has a set of foundations they can trust, to stand on their own feet and help others.

Six principles

1. Evidence. Every lesson lists sources and one of four labels: Verified, Inference, Expert judgement, Needs checking.
2. Truly free. No fees, no ads, no selling of data.
3. Privacy for children. We never publish a child’s name, photo or voice.
4. Safety. Every lesson has a Safety section. Lessons about the mind always include helpline numbers.
5. Accessible. Printable, clear text, works on weak phones and slow connections.
6. Integrity. No exaggerated claims, no use of other people’s brands, mistakes corrected in public.

Who writes the lessons?

The author is a father who works in auditing and training. Lessons are written with an AI assistant, sources are checked, and then the lessons are tried with his own family before publishing. Results from one family are not scientific evidence; each course says so.

About the translation

The site is written in Vietnamese. English pages are translated with an AI assistant and reviewed by the author. Some examples are adapted for families outside Vietnam. If the English and Vietnamese pages differ, the Vietnamese page is the reference. If you see a translation error, please tell us through the sharing page (in Vietnamese; adults 18+).

Privacy

• The site uses no cookies, no tracking tools and no ads.
• The site loads no fonts or code from other websites.
• Tools on the site (if any) save data only on your device and send nothing anywhere.
• When you choose a language (Tiếng Việt or English), your browser remembers that choice on your device. The site does not send it anywhere.
• If your browser is not set to Vietnamese, the site asks Cloudflare one question: is this visit from Vietnam? The answer is only “yes” or “no”, used once to decide whether to suggest English. Nothing is stored.
• Our hosting provider (Cloudflare) may keep basic technical logs to run the service and block attacks.

The sharing page stores only what you write and choose to show; it never stores IP addresses, emails or phone numbers. Full details are on the Vietnamese privacy section.
