Next · Trash has no accounts and no database. This page explains the little that does happen, and who the few third parties are.
Who is responsible
The data controller is Tiago Morais, an independent developer based in Spain. Contact: tiago_morais@me.com. This notice covers trash.nexthq.app and explains your rights under the GDPR.
The camera never sends a picture anywhere
When you point the camera at a barcode, the video stays on your device. The barcode is decoded in your browser by a library that runs there — no photograph, frame or video is ever uploaded, stored or transmitted. Nothing about the image leaves the phone. The only thing that ever travels is the barcode number it read.
What is sent, and where
- The barcode number. It goes to this site's own server, which forwards it to Open Food Facts and returns the answer. The hop exists for a dull reason: the Open Food Facts API asks callers to identify themselves with a custom User-Agent header, and a browser is not allowed to set one. We do not keep a record of what you looked up.
- Nothing else. There is no account, no profile, no history and no identifier attached to that request.
- Our hosting provider keeps standard server logs, including IP addresses, for a short period as part of running the service. We do not read them to build any picture of a visitor.
If you contribute packaging data
You can optionally send a packaging material back to Open Food Facts, which asks for your Open Food Facts username and password. Those are posted from your browser straight to Open Food Facts. They do not pass through this site's server, and we never see, store or log them. What you contribute is governed by Open Food Facts' own terms.
What stays on your device
Three things, in your browser's local storage — not cookies, and never sent anywhere:
- the country whose bin rules you are using;
- your light or dark theme choice;
- a count of contributions you have made, so the app can thank you.
Clearing this site's data in your browser removes all three. There are no cookies, no analytics, no trackers and no advertising on this site.
Who processes anything for us
Fly.io (hosting) and Open Food Facts (the product database the answers come from). That is the whole list. Nothing is sold, and nothing is shared for marketing.
Your rights
You have the right of access, correction, deletion, restriction, portability and objection. In practice there is almost nothing here to exercise them against — we hold no account and no record tied to you — but if you have a question, write to tiago_morais@me.com. You may also complain to the Spanish supervisory authority, the AEPD (www.aepd.es), or to the authority where you live.
