Privacy
What we record, what we do not record, and how you switch it off
The one-sentence version
- Anything you enter in a self-assessment tool does not leave your browser. There are no exceptions.
- We record only anonymous usage statistics: how many people view which page, how many complete a self-assessment, and which grade the result fell into.
- No cookies are set, no cross-site tracking identifier is created, and there is no advertising remarketing.
- If your browser has Do Not Track or Global Privacy Control switched on, this site will not load any statistics script at all.
- The clinical pathways and the smart report system have no statistics script of any kind.
Why anything is recorded
This site is written by one person outside clinic hours. Deciding what to write next, working out which self-assessment has questions so long that people do not finish them, and whether the red-flag warnings really do catch the people who need to be seen — all of that takes a little data.
But the usage records of a health information site are very sensitive. Information of the kind “this device looked up coughing up blood” is special category personal data under Article 6 of Taiwan’s Personal Data Protection Act. So we have drawn the line very clearly: the process may be recorded; the content never is.
What we record
| Event | What it contains | Why it is needed |
|---|---|---|
| Page view | which URL, the referring site, device type, country | to know which topics people need |
| Self-assessment started | which symptom’s tool | compared with “completed”, it shows how many people give up part way |
| Self-assessment completed | which tool, and the result grade (see a doctor as soon as possible / an outpatient clinic appointment soon / arrange an assessment / you can watch and wait for now) | to see whether the tool really does catch the people who need to be seen |
| Scroll depth | reaching 50% and 90% of the page | whether an article is too long, and where it loses the reader |
| FAQ expanded | which question was opened | to know what people really care about |
| Link clicked | clicks on appointment booking, LINE, the smart reports or further reading | to see which route really is helping people |
What we never record
This data has never left your device
- The content of any answer. Whether you ticked “coughing up blood”, “weight loss” or “night sweats”, or entered your age, your weight or your FEV1 — these exist only in your browser’s memory, and disappear when you close the tab.
- Name, telephone number, national identification number, medical record number, email address. This site has no field that collects any of these, and no membership system.
- Your full IP address. The statistics service uses it only to work out roughly which country and which type of device, and does not retain an address that can be traced back to an individual.
- Cross-site tracking identifiers. This site sets no cookies, and has no Facebook Pixel, no Google Ads remarketing tag and no advertising tracking of any kind.
- Screen recording and mouse movement. This site does not use session replay tools (such as Hotjar or Clarity), because they would record which options you ticked.
Which pages have it and which do not
| Section | Anonymous statistics | Notes |
|---|---|---|
| Home | Yes | records only the page view and which symptom entry point was clicked |
| Symptoms (6 pages) | Yes | includes the self-assessment flow and the result grade, not the content of the answers |
| Health Topics (11 pages) | Yes | page views, scroll depth, FAQ expansion, link clicks |
| Wellness (6 pages) | Yes | as above; the self-assessment tools likewise record only the grade |
| Clinical pathways (13 tools) | None at all | these pages do not load any statistics script |
| Smart report system (14 pages) | None at all | as above. The report values stay entirely on your device |
The tools we use
- Umami — open-source, cookie-free website statistics. This site uses it to record the events in the table above.
- Cloudflare Web Analytics — cookie-free page-view statistics, as a backup.
- Google Search Console — this is a tool on the search engine’s side. It does not run any script in your browser, and only lets us see aggregate data on which search terms bring people to this site.
The fonts on this site come from Google Fonts; the icons and the pages themselves are served by this site’s own host. Beyond that there are no other third-party resources.
How to switch it off
There are three ways, and any one of them works:
- Switch on Do Not Track or Global Privacy Control in your browser. This site detects it and does not load the statistics script at all.
- Press the button below. This stores a note in your browser, after which browsing this site in this browser will not send any statistics.
- Use any ad blocker or tracker blocker. It will not stop the site working — every self-assessment tool works normally while completely offline.

Your rights
Under the Personal Data Protection Act, you have the right to enquire about and review your own personal data, to have it supplemented or corrected, to request that its collection, processing and use stop, and to request its deletion.
For this site, though, there is one practical limitation: the statistical data we collect contains no field that could identify you, so we have no way of finding out from the database which records are yours. This is not an evasion — it is exactly what the design is for. If you want to stop being counted in the statistics, the opt-out button above is the most direct way.

Revisions
If this statement changes, the date below will be updated. If a feature that collects more data is added in future, this page will be updated before that feature goes live, rather than written up afterwards.
