PassIQ.se is a Swedish SaaS focused on digital product passports, offering insights from customer questions. That's a niche but legitimate concept. However, for a business handling product data and customer queries, the site is missing key elements you'd expect from a trustworthy software provider. There's no privacy policy or terms of service, which is a red flag for GDPR compliance. The company behind it is hard to identify — the domain is only 4 months old and ownership is not publicly visible. While the technical infrastructure is solid (good encryption, reliable hosting), the lack of transparency means you should treat passiq.se with caution. If you're considering using their service, ask directly for company details, a data processing agreement, and proof of real operations. An established SaaS would have these readily available. For now, we cannot confidently say passiq.se is a scam, but its trust signals are too weak for an unconditional recommendation.
