A Letter to Kind People

If you are reading this, perhaps you are someone who loves technology, cares about security, or simply pays close attention to details that others might overlook.

First of all, I would like to sincerely thank you!

We may never have met, but I believe that if you have taken the time to read this far, you probably share the hope that technology can become better, safer, and more valuable to the people who rely on it. For that alone, I am sincerely grateful.

I understand that no software is perfect. Although I have spent countless hours developing, testing, and refining Bác sĩ bên con, there may still be issues involving medical content, calculation algorithms, user experience, performance, or security that I have not yet discovered.

If you happen to find any vulnerability, bug, or inaccuracy, I sincerely hope you will consider reporting it to me before publicly disclosing or exploiting it.

I simply ask for the opportunity to fix the problem before it has a chance to affect the families who rely on this website. What worries me most is not that a website might fail, but that a parent could receive incorrect information while trying to care for their child.

Every report you send does more than improve a piece of software — it helps protect thousands of parents and children who use Bác sĩ bên con as a trusted source of health information.

I deeply appreciate every suggestion, whether it comes from physicians, pharmacists, nurses, software developers, cybersecurity professionals, or simply thoughtful users. Every report will be carefully reviewed, thoroughly verified, and addressed as promptly as possible.

If your finding meaningfully improves the quality or security of the website, I would be honoured to send you a small token of appreciation in recognition of the time, effort, and goodwill you have devoted to this project. It may never fully reflect the value of your contribution, but I hope it can carry my sincere gratitude.

I do not see these reports as people "finding bugs." To me, they represent partnership. Whether it is a typo, an improved calculation, clearer wording, or a critical security vulnerability, every contribution helps make Bác sĩ bên con better than it was yesterday.

I believe technology truly matters only when it is used to protect people and improve lives. Every bug fixed, every piece of information updated, and every vulnerability resolved brings Bác sĩ bên con one step closer to becoming a safer and more trustworthy resource for families.

We may never know which children have ultimately benefited from those contributions. But I believe that every issue resolved today may help a family remain calmer when their child develops a fever in the middle of the night, help a parent avoid an inappropriate decision, or simply help a child receive better care.

If we share that same purpose, I would be truly grateful to have you alongside me.
