Privacy

This website

This site does not track you. There are no advertising or analytics trackers, and we use just one cookie: a preference cookie (dj-lang) that remembers which language you picked if you click NL or EN yourself, or if you arrive through djensur.nl. Beyond that we count visits anonymously: for each page viewed we store the language, your browser's time zone, the site you came from and whether you are on a phone or a computer. No name, number or IP address is attached; none of it can be traced to a person.

There are two forms on this site. The first is the list for people who want to stay up to date. We store what you choose to fill in: your email address and language, and optionally your name, phone number, who you are joining as, how you found us and what you look forward to. We only use it to email you when there is real news about Djensur, based on your own sign-up. We keep your sign-up until six months after the launch at the latest; after that we delete the list. Want to be taken off sooner? Email contact@djensur.com and we will delete everything you shared with us.

The second form is the demo request on the page for dance studios. We store what you fill in: the name, website, city and size of your school, your name, your role and your email address, and optionally your phone number, when suits you and what you would like to talk about. We only use it to prepare the demo and to get in touch with you, based on your own request, and we keep it no longer than needed to handle the demo and the follow-up.

When you submit a form, we also store your IP address in a separate table that only counts how often one address submits in a short time. It exists purely to stop someone from submitting a form hundreds of times in a row. It is kept apart from what you fill in, and we use it for nothing else. We do this based on our legitimate interest in keeping the forms usable.

The distance counter on the homepage estimates how far you are from her stage in Seoul. That estimate comes from our own hosting provider, which already handles your connection when the site loads; your IP address does not go to an extra party for it and we store none of it. We do this based on our legitimate interest in making the counter work. If you tap "exact distance", your device asks once for your precise location: those coordinates are only used on your device to compute the distance and never leave it. Say no and the estimate stays, and if even that fails we show no distance.

The founder login at /founder stores a session token in the browser storage of that device after signing in. That is purely functional and does not track you.

Who we are

Djensur is a dance app by Niko Zeldenthuis, trading as Djensur in the Netherlands. We are responsible for your data. Questions or a request: email contact@djensur.com.

What the app keeps

Your account (name, email), your profile (bio, gender, place of residence or country, photo), your date of birth for the age check, your uploaded choreos and the processed result, your practice stats and self-assessments, your friends, your community posts and comments, and your chat messages.

Chat messages disappear automatically after 30 days. If someone reports a conversation, we look at that conversation to assess the report. We do not use your data for ads, there are no trackers from other companies in the app and we never sell your data.

If you register a dance school, we fetch the website you give us once, only to see whether the email address you enter is on it or ends in the same domain, and we send a code to that address. If you become a creator, we fetch your public TikTok profile or the YouTube video you point us to once, only to find your code there. What we saw (the address, a fragment of the bio or description) we keep for at most ninety days as evidence and then delete. We do this on the basis of the agreement you enter into with us.

What the app measures

To make the app better, we send data about how it is used to our own server in Europe: which screens you open, for how long and what you do there, such as opening a dance or starting a session. We also send when the app opens, performance figures from the stage with your device model, and error reports when something goes wrong. If you send us a report yourself or the app closes unexpectedly, we include a short technical log of that moment, cleaned of personal data. From your internet connection we work out roughly which town or region you are in. We do not store your internet address itself.

None of it contains camera footage, video or anything from your private messages. We use it to see where the app falls short, to make it better and to help you when you get stuck, based on our legitimate interest. What you do in the app we keep for 90 days, and we share it with no one. Delete your account and all of it goes with it.

Processed on your device

Djensur processes your live camera feed entirely on your own device; none of it gets uploaded. Recordings of your sessions live on your device and only go online when you share them or publish them in the community.

Choreo videos you upload are processed on your device and stored only as the processed result, so your library is available on all your devices.

Who we share with

Only the services needed to run the app: Supabase with European data hosting for your account and data, Cloudflare for storing your processed videos, Vercel for our website and the location estimate from your connection, and Apple and Google for the app stores and notifications. We sell your data to no one.

Minimum age 13

Djensur is for users aged 13 and over. If you are under 13 you cannot create an account yet. We ask for your date of birth to check this and do not verify identity. If you are under 16, protected mode is on: your profile is private, strangers cannot message you, and things stay quiet between 22:00 and 07:00. You cannot switch that mode off yourself. If you think someone under 13 has an account anyway, email contact@djensur.com.

Your rights

You can view, correct and delete your data, restrict processing, object to it, port it and withdraw consent you gave.

Deleting is something you do yourself in the app; see below for how. For the other requests email contact@djensur.com; we respond within the legal time limit.

Deleting your account and data

You do this yourself in the app, in three steps: open Settings, choose "Delete my data" and confirm. Your account, profile, choreos, stats, messages and community contributions are then erased irreversibly and you can no longer log in.

If the in-app route does not work, email us at contact@djensur.com from the email address on your account and we will delete it for you.

Filing a complaint

Not happy with how we handle your data? Email us first; we are happy to sort it out. You also always have the right to file a complaint with the Dutch Data Protection Authority (autoriteitpersoonsgegevens.nl).
