Every day, investigators face the impossible task of identifying anonymous hotel rooms from fragments of video or photographs. These rooms become the silent backdrops of exploitation: unrecognisable, interchangeable, and impossible to pinpoint without help.

room・id turns that silence into information.

By combining the power of crowdsourcing with advanced AI-driven image recognition, room・id creates a living, growing database of real hotel-room images from around the world. Travellers contribute photos of their rooms, and our system analyses and organises them into a secure, searchable index.

It’s a bridge between ordinary travelers and the experts fighting human trafficking. A tool built with privacy, safety, and precision at its core. A system designed to help investigators locate victims faster and hopefully save lives.

room・id is designed, envisioned and crafted by René Krewinkel, an experienced digital bohemian, and Jasper Smitz a talented junior AI and backend developer.

At —kr, we design and build thoughtful digital experiences. We combine clear aesthetics with purposeful engineering — turning complex problems into simple, humane solutions that support real-world action. Every project begins with the same question: 'how can we make a positive and lasting impact?'

We believe in thoughtful craft, privacy-first design, and using technology with intention.

We designed this app with one guiding principle: your personal information is none of our business. The app - or website - does not collect, store, or track any personal or relatable data while you use it. We do not create user profiles, we do not monitor your behavior, and we do not run analytics that follow you around. And although cookies are delicious, you won't get any from us. Ever!

The only information we receive from you comes in two cases: 1) when you choose to contact us through the built-in contact form, and 2) when you voluntarily submit photos of hotel rooms through the app.

Information we collect in the app

1. The images you took with the app, we will have no access to any other images on your device.
2. Your current location (so we can pinpoint exactly where your hotel or AirBnB is located).
3. A untraceable, unidentifiable abstract ID we add to your photos so we can notify your app when one of your photos shows up in a search.

Submitted images are only of hotel rooms—never of people. The app is designed to ensure that no identifiable individuals appear in the photos, and images are used strictly for the purpose of analysing room features to support our mission. If our systems detect people in the submitted images, the entire image is discarded and deleted.

Outside of these user-initiated actions, no data leaves your device. No tracking. No hidden collection. No exceptions.

Your privacy stays fully protected, exactly as it should.
