This site collectsnothing.
No cookies, no analytics, no third-party requests. The list of what leaves your browser is short enough to print here.
One exception, and it is not ours to remove: GitHub serves these pages and, like any host, sees the request that fetches them.
What this site does
Everything this page needs comes from guestgraph.io, fonts included. Nothing is fetched from anywhere else, so no third party learns that you were here.
localStorage: gg-lang = "de" | "en"
That is everything that gets stored: your choice of language, two letters, so the next page knows it. It reaches no server and identifies nobody.
Not used at all
- CookiesNone, of any kind. There is no banner because there is nothing to consent to.
- AnalyticsNothing counts you, and nobody is told that you were here.
- Third-party requestsFonts, images and styles all come from this origin. No CDN sees your address.
- Forms and accountsNothing to fill in, nothing to sign up for, nothing to store.
- FingerprintingNo attempt is made to recognise you across visits. The language key is not an identifier.
Guest data, when there is any
The hosted service is not running, so there is no guest data in it. This is how it will be handled when there is — written down now, because a hotel asks this before it asks the price.
The hotel is the controller; GuestGraph is the processor. You decide what is collected and why. It is processed on your instruction, for your purposes, and for nothing else.
A data-processing agreement, on request. The revised Swiss DSG and the GDPR both apply — Swiss hotels and German or Austrian ones are one market here. Switzerland's adequacy decision makes data moving between the two less of an obstacle than it is often assumed to be.
The cloud is not chosen yet. No provider, no region, no guest data — because nothing is running. Whichever it turns out to be will be named on this page before the first record is processed, not after.
Self-host and none of this applies. Apache 2.0, your infrastructure, your data: nothing leaves the building, and there is nobody to sign an agreement with.
Who runs this
GuestGraph is built and run by Robert Blust. It is not a company: one person, working in the open, with the engine under Apache 2.0 for anyone who wants to read what it actually does.
There is no imprint yet, and that is deliberate rather than an omission: nothing here can be bought, so there is no transaction for one to belong to. When the hosted service opens it arrives — name, address and contact — on a page of its own, because an imprint is not a privacy note. The same day, the billing page stops saying it is not open.
