Frequently asked questions
The questions people ask before they trust a health record to anyone. Answered as honestly as we can, including where the answer is “not yet”.
Why should I give you my most sensitive data?
You should not give them to anyone without a reason. What we can offer instead of a promise is a list of things you can check: the record is stored in the EU, access to it is denied by default at the database level, every opening of it leaves a log entry nobody can delete, and the assistant has no permission to write to it.
You can also start with one value instead of your whole history, and see whether the thing is worth it before you put anything more in.
What if you get hacked?
We cannot promise it will not happen; anyone who does is selling something. What we can describe is what limits the damage: access is closed by default rather than open, documents have no public address, links to them expire in sixty seconds, and the audit log is append-only, so an intrusion leaves traces that cannot be cleaned up.
If it ever happens, you will hear it from us, with what we know and when we knew it.
Who pays for this?
The KanzenKai Foundation, a non-profit registered in Bulgaria under number 208631083. You can look the number up.
There are no ads and no data sales, so there is nothing about you that anyone here needs to monetise.
Will you sell my data to insurers?
No. Not to insurers, not to employers, not to anyone.
The check you can make on that statement is the audit trail: every access to a record is written down and the entry cannot be removed afterwards.
What happens to my record if you stop?
If we ever discontinue the service, we will give notice in advance and make sure there is a way to obtain a copy of your record before it goes.
We are not going to promise permanence. A small project promising to outlive you is not a promise, it is a sales line.
How do I delete everything?
You can request a copy of your data or ask for it to be deleted. Today we do this on request at zen@kanzenkai.org, within one month. One-click export and deletion are on the roadmap — we will announce them the day they work.
We would rather tell you it is a request today than show you a button that does less than it looks like it does.
Is this not the same as the state health record?
No, and it is not meant to replace it. State systems show what healthcare providers have reported. A test you paid for privately, a paper discharge letter from years ago, and a measurement you took at home do not go there.
LZD is your own copy, which you fill in and you control.
I do not have time to type in years of history.
Then do not. Start with one value — the one you would want to show at your next appointment — and stop there.
A single value is already more than a folder in a drawer, and you can decide later whether the rest is worth the effort.
Can I keep a record for my mother or my child?
Not yet. Keeping a record on behalf of another person needs a proper model of authority and consent — who may act for whom, with what proof, and how it is withdrawn. That does not exist yet, and we would rather say so than let you build something on an arrangement we have not thought through.
The service is for adults keeping their own record.
Will my doctor even look at this?
That is up to them, and a consultation is short. What tends to help is not handing over an app, but arriving with the thing you would otherwise be trying to remember: which values, on which dates, in what order.
Sharing gives access to a defined part for a defined time, and you can take it back — but the useful part is usually just being prepared.
Can the assistant tell me what my results mean?
It cannot, and it is built not to. It will show you what is recorded and where each statement comes from, and it will say when the record does not contain enough to answer.
What a value means for you is a question for your doctor, who can examine you. Software that answered it would be a different kind of product, under different rules.
