Card based note taking app from London
United KingdomFree plan Ownership reviewed, controller unresolvedScope verdict
This service remains visible for context, but it is not counted or recommended as a European-controlled option.
Supernotes is a note taking app built by a team of two based in London. Notes are short cards that can be tagged, nested, linked and shared, and you can view them as a list, grid, columns, a graph, a map, a table or as flashcards with spaced repetition. Apps cover macOS, Windows, Linux, Android, iOS and the web.
The editor handles extended Markdown, LaTeX equations and a wide array of keybindings, with a focus on fast syncing and easy sharing. The interface exists in several European languages thanks to community translations, and the founders are active on the community forum. As a European alternative to US note apps, it suits people who prefer many small linked notes.
The free Starter plan includes the core features, cross device sync, collaboration and publishing, starting with 100 cards that can be extended through achievements or referrals. Paid Unlimited plans remove the card limit and add AI features, with discounts for longer commitments.
Data and operations
Verified operational dependencies, shown separately from ownership and from the service's core data hosting.
Public website
Why this matters
Public DNS routes website visits through Cloudflare. Visitor IP addresses and request metadata can reach this non-European provider; this does not identify the core service's data location.
Incoming business email
Why this matters
Published MX records route incoming business email through Google Workspace. Correspondent details and message content can therefore enter this non-European provider's systems; MX does not reveal the configured storage region.
Authorised outbound email
Why this matters
This domain authorises Google Workspace to send email. If active, recipient details and message content can be processed by this non-European provider. SPF does not reveal its configured storage region.
