Scanner conversationsAccess links are temporary. Older conversation records are pruned automatically; the current build prunes them after about 30 days.

Health emergency profile and vaultUntil you remove it or request deletion. Access by doctors is logged.

Deleting your data

  • Owners can download their tag data and submit an erasure request from My account.
  • You can also write to support@bidua.in with your Tag ID or order ID.
  • Deleting data deactivates the linked QR identity. Records we must keep by law are retained but limited to that purpose.
  • We aim to respond within 30 days.
