HOW IT WORKS
A local workspace for contact files.
vCard Editor is designed for the moment when a contact file needs attention, not another account or upload form.
What happens when you choose a file?
Your browser reads the file using the File API. The editor parses its vCard blocks, builds an editable contact model, and keeps the working data in the current browser tab.
What leaves your device?
The initial workspace does not send contact contents to an application server. Downloads are generated locally as a new file. We also avoid third-party analytics inside the processing surface.
What should I expect?
The first release focuses on common VCF files and transparent feedback. Unsupported or malformed lines should be surfaced as warnings rather than silently hidden.
Verify it yourself: open your browser developer tools, choose the Network tab, load the synthetic sample, and confirm that no request contains the file contents or contact values.
