Are my personal UPI details, transaction notes, and birth dates private when using Meema Utility Tools?
Yes, 100% safe. All QR code matrix rendering, age calculations, percentage math, and PDF generation execute locally in your browser's JavaScript memory. Zero personal details, UPI VPAs, or dates are ever sent to remote servers.

Our Age Calculator accounts for leap years, variable month lengths (28, 30, 31 days), and timezone offsets to provide exact age in years, months, days, hours, and minutes.
