NEW LOOK • A new app icon: the KnotTheory trefoil, with a badge for personal tax. TAX ESTIMATE AND FILE RETURN • Fixed a Tax Estimate that could show $0 after an app update moved your documents. • File Return now builds the refund from your income and tax, not from payments alone, and no longer counts withholding twice. • Blank fields show placeholders instead of 0.00. ON-DEVICE AI • Document Chat with the on-device Gemma 4 model no longer closes the app on iPhone. • Fixed the Gemma 4 model download after the files were renamed at the source. • Chat now knows the tax year and country you are working in. • Quitting during extraction no longer crashes. EVERYDAY FIXES • Years display as 2025, not 2,025. • Adding an institution creates its tax year, and a new year is selected straight away. • Year Comparison uses all your amounts and fits the iPhone screen. • Vault: import passwords from CSV on iPhone; Face ID prompt explained. • Export: share sheet on iPhone. • Scanner: Done closes the scanner and no longer saves duplicate PDFs. • Help and About now say plainly that your data stays on your device.
