When you should encrypt first
If you need to share, upload, or store across devices, encrypting first reduces leak risk.
Before sharing contracts/quotes
Encrypt before sending to clients or partners to avoid accidental forwarding or leaks.
Sensitive internal files
Payslips, financial reports, customer lists are safer when encrypted first.
Before cloud/chat uploads
Encrypt before cloud drives or messaging to keep storage and transit safer.
Across devices
When moving between phone and computer, encryption protects against loss or casual access.
Tip: encryption only affects the exported file.
