Supernotes

Supernotes is a modern cloud-based note-taking SaaS that prioritises speed, collaboration, and structured knowledge (via its “notecard” system), but from a privacy perspective it follows a standard centralised model. User data—including notes and interaction metadata—is processed by the provider, with no zero-knowledge encryption or self-hosting options to mitigate this. Its UK jurisdiction offers moderate legal protection (stronger than US, weaker than Switzerland/EU in some respects).

Cloud-first collaborative architecture Designed for sharing, linking, and real-time editing of “notecards” Small independent company (low scale, low complexity) Founded 2018, small team (~2–10 people) Data collection typical of SaaS apps Includes identifiers, usage data, and potentially user content for functionality and analytics No structural privacy features No zero-knowledge, no local-first mode, no self-hosting Lower ecosystem lock-in than giants Smaller platform, easier to leave vs Notion/Google Docs
