Privacy Statement

Last updated: 28 October 2026

1. Who we are

LudensFlow is a platform of teaching structures for education. The controller for the processing of your data is Oksana Oliinyk, based in the Netherlands. Contact: hello@ludensflow.com.

2. What data we keep

From your account: your email address, your name (optional), your language choice and, if you sign in with a password, a hashed version of it. If you sign in with Google or Microsoft, we receive only your email address and name from them; we never see your password. From your work: your preparations, lessons, variations, class labels, curriculum, reflections (including any free text), ratings, comments, favourites and share links. From your usage: which structure you played, when, for how long, and with which class label. From the structure assistant: which answers are chosen in the conversation and which structure is taken, not linked to any person or account, so we can see which questions help. From your first visit: which link brought you here (for example a post on Instagram or LinkedIn) and which page you landed on; if you create an account, we keep that with your account, so we know which channels actually reach teachers. If you start a structure without an account, this browser remembers which one; if you then create an account here, we link those earlier runs to your account, only so we can see how teachers begin. They do not appear in your own overview. About your classes: the first names of your students, if you enter them yourself to draw turns and make groups; only you see them.

3. What we do not ask of students

Students have no account and we ask them for no name or email address. You may enter the first names of your class yourself, to draw turns and make groups; they live only in your account, are never linked to anything a student sends, and go when the class or your account does. A live link and a poll work with an anonymous device id, only so that one phone counts once. Poll answers and anonymous participant ratings are stored without any link to a person. Free text from a poll is seen only by the teacher, who can also delete it. A class feedback (three questions, once a month) is stored as counts per class only; there is no row per device, and the device id is erased after that day.

4. What we use your data for

To provide the service: signing in, saving and finding your work, playing and sharing structures. To improve the platform and give knowledge back to the profession: only anonymised and aggregated, so that no person, class or school is ever recognisable; free text from reflections never takes part in this. To email you: verification, password reset and account messages go through Resend. In addition, we add the email address of every new account to our newsletter list in your language at Loops, so we can tell you what is new; we do this on the basis of our legitimate interest in keeping you informed as a user. Every newsletter has an unsubscribe link, and unsubscribing has no effect on your account.

5. Who else is involved

We work with: Vercel (hosting, visitor statistics and speed measurement), Supabase (database, hosted in the EU), Resend (transactional email), Loops (newsletter), Google and Microsoft (only if you sign in with them) and Ahrefs (cookieless visitor statistics). These parties process data on our behalf under a data processing agreement. We do not sell your data and do not pass it to third parties for their own marketing.

6. How long we keep your data

As long as your account exists. If you delete your account from your profile page, your account data and all your work are erased immediately, and we also remove your email address from the newsletter list. Anonymous data, such as poll answers, is linked to nobody and stays anonymous. Aggregated statistics stay aggregated.

7. Team scan

When you start a team scan we keep your name, e-mail address, the names of the school and the team, the team size, your language, and whether you agreed to be contacted. That agreement is a separate checkbox; without it you only get the scan’s own mails. Team members answer without an account: we keep their answers, a random device number (so one phone counts once) and the day of the answer, but no name, no IP address and no time of day. The report shows only the team’s total, only from five answers, and never a single answer. After 24 months we delete the answers, and your own details too unless you agreed to be contacted.

8. Cookies

We use a functional cookie to keep you signed in and a cookie to remember your language choice. Vercel Analytics uses an anonymous statistics cookie, a cookie of our own (lf_src, 90 days) remembers which link brought you here, and a second one (lf_guest, 90 days) which structures you started without an account; you can refuse all three in the cookie banner. Ahrefs measures visits without cookies.

9. Your rights

You have the right to access, correct, delete and port your personal data, and you can object to a processing. Send a request to hello@ludensflow.com, or delete your account directly from your profile page. If you are unhappy with how we handle your data, you can lodge a complaint with the Dutch data protection authority (Autoriteit Persoonsgegevens).
