How CardSpark Handles Your Data

Data Storage & Security

All your business card data is stored locally in your browser using localStorage. This means:

  • Your data never leaves your device unless you choose to share a card
  • We cannot access, view, or collect your personal information
  • Clearing your browser data will delete your saved cards
  • Your cards are only accessible from the browser where you created them

Image Uploads & Privacy

When you upload images (avatars, logos, or paper cards):

  • Images are converted to data URLs and stored locally in your browser
  • We don't upload images to our servers or any cloud storage
  • Paper card images are only displayed for your manual reference
  • No OCR (Optical Character Recognition) is performed on uploaded images

Public Cards & Links

When you generate a public card link:

  • The card data is still stored locally in your browser
  • Public links only work when accessed from browsers that have the card data
  • No data is transmitted to external servers for public viewing
