Size is fully editable in millimetres. The 123 × 63 mm quick preset is a note-sized layout reference only; this is a private silver certificate, not Indian currency or a legal-tender banknote. Existing issued certificates retain their recorded certificate data; the saved design is used for previews and future downloads.

Sync behaviour

The admin app keeps a local working copy. Sync securely sends records to the central Google Sheet; the public portal reads only allow-listed certificate fields from that same Sheet. Existing cloud records are merged by record ID and are not automatically deleted. Use one designated admin computer to avoid conflicting edits.

Last sync request: Never
