Frequently Asked Questions (FAQ)

Where is my data stored? Is it uploaded to any server?

  • Your data is stored locally in your browser (localStorage/IndexedDB) by default and is not uploaded to any server.
  • Clearing browser cache may remove your data. We recommend exporting JSON for local backup once the export/import feature is available.
  • We do not collect personally identifiable information (PII). Any analytics is aggregated for product improvement (see Privacy Policy).

Why can’t I export PNG or PDF directly on mobile?

  • Mobile browsers provide limited support for html2canvas and PDF generation, which often leads to cropped content, stretched resolution, or crashes.
  • To guarantee export quality, we only enable PNG/PDF export on desktop browsers. You can continue to view and edit data on mobile.
  • When you need an export, open the same page on a desktop browser and use the export button, or print to PDF from desktop.
