Nothing in this app sends data to any server, database, or cloud โ including when it's hosted on Netlify, GitHub Pages, Google Drive, or your school's LMS.
This is a single static HTML file. There's no backend, no database, no analytics, no tracking. Everything you see is computed by JavaScript running inside your own browser.
The Excel file is read by your browser using JavaScript. The totals are calculated on your device. The file never leaves your computer โ it's not uploaded to Netlify, not uploaded anywhere. Close the tab and the data is gone.
Their answers live in their own browser. When they hit "Email to Teacher," "Copy My Tax Return," or "Save as PDF," the data goes only to whichever channel you chose โ your inbox, their clipboard, or their device. The host never sees it.
Netlify (and similar services like GitHub Pages, Vercel, etc.) only deliver this file to whoever loads the URL. They host the static page itself but have no way to peek at what visitors do inside their own browsers. This is the same model as a printable PDF posted to a website โ the website doesn't see what someone writes on the printed copy.
Open your browser's Network tab (Right-click โ Inspect โ Network). Then upload your Excel file or fill out the form. You'll see zero outgoing requests โ no data leaves your machine.
If a student emails you their tax return, that email goes through whatever email service they use (Gmail, school email, etc.). That's a normal email โ separate from this app. Same for "Copy My Tax Return" โ once they paste it somewhere, that destination's privacy rules apply.

In the real world, the government collects taxes to pay for things everyone uses โ like schools, roads, firefighters, and parks. In our classroom, taxes help keep our economy fair and teach us responsibility.
Write 2-3 sentences: What would happen if nobody paid taxes? What couldn't our classroom (or community) afford?
Students should connect the abstract idea of taxes to real, shared things they use every day. Listen for examples that show they understand pooled resources โ money everyone contributes a little to, that pays for things no single person could afford alone.
"If nobody paid taxes, our school wouldn't have books, computers, or even buildings. Police and firefighters wouldn't get paid. Parks would close down. Taxes are how our community pays for everything we share."
"In our classroom, taxes pay for the rewards, supplies, and field trip fund. If nobody contributed, we couldn't afford those things and only the kids who could pay would get them."
โข Mention of shared/public things (schools, roads, fire, police, parks).
โข Understanding that taxes pay for things everyone benefits from.
โข Connection to fairness โ everyone helps a little so everyone gets the benefit.
Upload your ClassBank transactions export to get a per-student breakdown of salary, bonuses, expenses, purchases, fines, and refunds โ so you can quickly verify the numbers each student wrote on their tax return.
