Terms of Use

Lamduan Tracker is a personal health logging tool. You enter your own weight, food, training and fasting windows, and it summarises the numbers and draws your history back to you.

Using this site means you accept these terms. If you do not accept them, please do not use it.

Lamduan is not a medical device. It does not diagnose, treat, cure, or prevent any medical condition, and it is not a substitute for examination or treatment by a healthcare professional.

This is the most important clause in the document.

This site is a notebook that does arithmetic. It is not a doctor, not a dietitian, not a health adviser. The numbers, charts, averages, heart-rate zone descriptions, food database values and every explanatory note are general reference only — not diagnosis, treatment, or advice for your particular body.

• Food database values are per 100 g, and every entry is labelled with where its number came from: some rows are a specific USDA database entry and carry its reference number, others are estimates with no reference table behind them. Real food varies widely; a packet label is always more accurate
• Heart-rate zones are based on estimates. Individual maximum heart rates differ by 10-20 bpm
• Fasting does not suit everyone — particularly during pregnancy or breastfeeding, with a medical condition, on medication that must be taken with food, or with any history of a difficult relationship with eating

Before changing how you eat, train or medicate, talk to a doctor or qualified professional. If something feels wrong with your body, see a doctor — do not wait on a number in this site.

• Registration details must be truthful, and the email must be one you can actually reach
• You are responsible for keeping your password safe and for everything done under your account
• One account per person — sharing one mixes two people's health data into something meaningless
• Under 20s need a guardian's consent before registering

• Attempt to reach another user's data, or break into the system by any means
• Send abnormally frequent requests that affect the service for others
• Enter or upload unlawful content, or content infringing someone else's rights
• Use anything from this site to give medical advice to other people

Accounts found in breach may be suspended or closed.

• The service is provided "as is", with no guarantee of uninterrupted availability
• It may go down for maintenance, change features, or drop parts of the service without notice
• Download your own backup regularly from the export page. Reasonable care is taken with your data, but no guarantee against loss is given

Every row you enter remains yours. The site owner claims no ownership of it, does not sell it, does not advertise against it and does not publish it. You can take it out or erase it at any time (see the privacy policy).

The software itself, the Lamduan name, the logo and the manual content belong to the site owner.

To the extent the law allows, the site owner is not liable for damages arising from using or being unable to use this service — including data loss, downtime, or health outcomes from decisions you made based on numbers shown here.

This does not exclude liability that the law does not permit to be excluded.

You may close your account at any time, from the mobile app or by writing to admin@mylamduan.com. Deletion is permanent and irreversible — download a backup first.

These terms are governed by Thai law.
