SebTechDevBot

SebTechDevBot is the fetcher of SebTechDev, a one-person app studio in the Netherlands. It reads public product recall and safety warning pages of Dutch shops and of the Netherlands Food and Consumer Product Safety Authority (NVWA), so the free app Terugroepactie can show people which products are recalled and what to do. Every recall in the app links back to the shop's own page.

What it does

• It fetches only recall and safety warning pages, never shop, account or checkout pages.
• It checks each source once every 30 minutes, waits between requests, and fetches a recall's own page only once.
• It follows robots.txt, including Crawl-delay.
• It doesn't run JavaScript, solve challenges or use proxies. When a site turns it away, it stays away.
• It doesn't copy product photos from shops, and nothing it reads is used to train AI.
