Privacy
Hangster, by UIUX SRL · last updated 24 August 2026
Hangster has no accounts and no database. We don't know who you are, and we've built it so that we can't find out.
Most privacy policies are long because the company collects a lot and has to describe it. This one is short for the opposite reason. Everything below is a description of how Hangster actually works, not a statement of intent. It covers both the app and the version that runs in a browser at hangsterapp.com/app; where the two differ, it says so.
What stays on your device
Your frames — their photos, their measurements, where the hanger sits — are stored on the device you used, and nowhere else. So are your arrangements. We have no copy. Delete the app, or clear this site's data in your browser, and they're gone; lose the device and they're gone with it. That's the trade for not holding them ourselves, and it's deliberate.
In a browser there is one thing we don't control: if the device runs short of space, the browser may clear what it has stored. Hangster asks to be exempt from that, and most browsers agree, but the decision is the browser's, not ours.
What briefly reaches our server
Two features need a server, because neither a phone nor a browser can do them consistently:
- Squaring up a photo. A frame photographed at an angle is corrected into a true rectangle. Only the frame itself is sent — your device crops the picture to the frame's edges before anything leaves it, so the room around it, and anyone in it, never travels at all. What is sent is corrected, returned, and deleted immediately: never written to a database, never linked to you, never kept.
- Building the AR preview. Your arrangement — the sizes, positions and thumbnails — becomes a 3D file so you can see it on your wall at true size. That file is parked briefly at a web address made of 32 random characters, so it can open in your phone's AR viewer, and is deleted after thirty minutes. The address is unguessable and is never listed anywhere.
Nothing else in Hangster reaches us. Documenting frames, arranging them and building the printed template all happen on your own device — in the app they work with no connection at all, and in a browser they work once the page has loaded. The template file itself never touches our server; the only thing that does is one tick on a counter, described below.
What we record
- Request counts, without you. Our server writes one line per request: what was asked for, whether it worked, and how long it took. The caller's IP address and all request headers are deleted before the line is written. This is how we notice a fault or someone attacking the server. It cannot tell us who was there.
- Crash reports, if Hangster breaks. Three fields: the version, the platform, and the error itself. The platform is a single word — which app, or which family of browser — never the full browser identification string, which would say far more about your device than we need. The server ignores anything else that might be sent, so nothing about you can be swept in by accident.
- How many templates were made. When the web version finishes building a template, it adds one to a number on our server. Not a line in a log — a single running total per day, and the request carries no content whatsoever: nothing about the arrangement, the frames, the paper, the time of day, or you. It exists because the template is built on your device and never travels, so this count is the only way we can tell whether the thing Hangster is for is actually working. A total per day cannot be turned back into a sequence of one person's actions, which is exactly why it is kept that way rather than as a list of events.
What we don't do
- No accounts, no email addresses, no passwords.
- No tracking, no advertising, no profiles, no analytics service of any kind. The daily template count above is the only measurement anywhere in Hangster: a number, with nothing attached to it.
- No third-party services receiving anything about you. Crash reports go to our own server, not to an outside company.
- Nothing is sold, shared or handed on. There is nothing to sell.
Where it runs
On a single server we rent in Falkenstein, Germany, inside the EU. Traffic to it is encrypted (HTTPS). The frames-and-arrangements data never goes there in the first place, so there is no database to breach.
Children
Hangster isn't directed at children and collects nothing from anyone, whatever their age.
Your rights
Under the GDPR you can ask what personal data we hold about you, and ask for it to be deleted. Our honest answer is that we hold none: with no account and no identifiers, we have no way of connecting anything on our server to a person. You can delete everything Hangster holds about you at any time by deleting the app, or by clearing this site's data in your browser — that's not a formality, it's genuinely all of it.
Changes
If this ever changes — for example if we add optional accounts so purchases can carry across devices — this page will be updated before the change ships, and the date at the top will say when. Anything that stores more than today will be something you opt into, not something that happens to you.
Who we are
Hangster is made by UIUX SRL, a company registered in Romania, which is the data controller for the little that's described above.
