I will build a clean offline HTML javascript tracker or calculator
Francisco P
About this gig
I will build a clean, responsive offline web tool using HTML, CSS and JavaScript. You can request a calculator, tracker, dashboard, form, budget tool or small internal utility. The result opens in a browser without a subscription or server by default. I can include local storage, validation, CSV export, summaries and clear setup notes. I will first confirm the required fields, calculations and output. No passwords, payment details or private credentials are needed.
