Does your payslip actually add up?
Drop in one payslip and get a full breakdown: does it balance, is your tax the right size for what you earn, what your real marginal rate is, what the next hour of overtime is actually worth, and what every line on the slip means. No signup. Nothing is stored — the file is read in memory and discarded.
Nothing is stored. Your password never leaves your device.
If your payslip is password-protected, it's decrypted right here in your browser using pdf.js — only the rendered image is sent for analysis, and it's held in memory, never saved to a database, never logged. We don't ask for your name, email, or anything that could link the document back to you.
That makes this check GDPR-light: with nothing stored, there is no personal data to breach or retain.
