Privacy
This explains what happens to information about you when you visit serein.works or send us the contact form. If you are a client, what happens to your own data is covered by the agreement we sign with you, which is a different document.

Who we are
The company responsible for this.
Serein s.r.o., Šoltésovej 7325/14, 811 08 Bratislava, registered in Slovakia under IČO 57011842 and DIČ 2122536834, entered in the Commercial Register of the Municipal Court Bratislava III, Section: s.r.o., File No 188762/B.
We are the controller of the information described below. For anything about your data, write to [email protected], and it will reach a person here directly.
What we collect
Three things, and one of them is not about you.
The contact form. Your name, your email address, and whatever you write in the message. Those three are needed because we cannot answer you without them. Your company, your position, and how you heard about us are optional, and the form works without them. There is also a question about which part of our work you are asking about, which has an answer selected already and tells us nothing about you.
Analytics. We count visits using software we run ourselves, on our own servers. It records which pages were opened, where visits came from, and roughly where in the world they were, and it does that without cookies and without anything that identifies you. It sets nothing on your device, and it does not follow you anywhere else.
Server logs. Our infrastructure records requests the way all web infrastructure does, including IP addresses, and those records are kept for a short period for security and for diagnosing problems.
There is nothing else. No cookies, no tracking pixels, no advertising, no embedded scripts from other companies, no session recording, no chat widget, and no mailing list. That is also why this site has no cookie banner: there is nothing to ask you about.
Why we are allowed to
Legitimate interest, and what that means here.
For the contact form, our legal basis is legitimate interest: you wrote to us, and we have an obvious interest in reading it and replying. That is also why there is no consent box to tick. A box would imply we were relying on your consent, and we are not, because sending a message you wrote on purpose is a clearer signal than a tick box underneath it.
For the logs, the basis is the same, applied to keeping the site working and secure.
The analytics needs no basis, because nothing it records is about an identifiable person.
Where it goes
Everything is in one place.
Everything runs on DigitalOcean infrastructure in Frankfurt, in our own private network. The website, the database holding contact form messages, and the analytics are all in the same place and under the same control.
That is the whole list. We run our own analytics and our own customer records instead of handing either to somebody else. Nothing you send us is passed to a third party, sold, or used for advertising.
Inside our company, a message you send is read by the people who answer enquiries.
How long we keep it
Twenty-four months, counted from the last time we spoke.
If you contact us and nothing comes of it, we delete what you sent after twenty-four months. The clock runs from the last contact rather than the first, so if we are still talking, it has not started.
If you become a client, your information moves under the agreement we sign with you, and that agreement says what happens to it.
Deleting it from our systems does not immediately remove it from our backups, because backups contain whatever was there when they were taken. We keep backups for thirty days, so anything deleted is gone from those within thirty days as well.
Server logs are kept for a short period and then go.
Your rights
All of it, by email, to a person.
You can ask to see what we hold about you, to have it corrected or deleted, to have us limit or stop what we are doing with it, and to have it sent to you in a form you can take elsewhere.
Write to [email protected]. There is no form to fill in and no account to create. We will answer within a month, and usually a great deal sooner.
You can also complain to the Slovak data protection authority, Úrad na ochranu osobných údajov Slovenskej republiky.
Changes
If this changes, the date changes.
We will update this page when what we do changes. The date at the top tells you when that last happened. If a change affects what we do with information we already hold, we will say so here.
