Do I need an account?
The public QR, image, calculator and currency tools are free to use without signing in. Saving app links and using business workspaces requires an account.
Where do my files and inputs go?
Image processing, QR artwork and calculator inputs stay in your browser. Currency rates are fetched from the server. Saved app links, account information and business records are stored to provide those account features.
Can I rely on financial calculations?
Calculators show formulas and assumptions so you can check the result. Loan estimates exclude fees, insurance and taxes. MEF reference rates can differ from a bank or money changer’s quote. Verify the final terms with your provider.
Where can I get help?
