Will my expense data be uploaded anywhere?

No. Every number you enter is written to your own browser's localStorage and nowhere else. There is no server endpoint, no analytics call, no third-party SDK touching your amounts. You can confirm by opening DevTools → Network and watching it stay silent while you type.

Can I sync expenses across devices?

Not automatically — that would require a server, which would defeat the privacy point. Use Export JSON on device A, email or AirDrop the file to device B, then Import JSON on device B. Round-trip takes about 10 seconds and gives you a deterministic, file-based backup you fully control.

How do I back up my data?

Click Export JSON. You get a single `.json` file containing every expense (id, amount, currency, category, date, note, createdAt). Drop it in iCloud / Dropbox / a private Git repo / a USB stick. To restore on a fresh browser, click Import JSON and pick the file — duplicates are skipped by id.

Can I add custom categories?

Not in this version. The 9 preset categories (dining, transport, shopping, entertainment, rent, medical, education, travel, other) cover the long-tail of personal spend, and capping the list keeps the per-category bar chart readable. "Other" plus the note field handles edge cases like "annual domain renewal".

What happens if I clear my browser cache?

Cached files (HTML/CSS/JS) are safe to clear — they get redownloaded. But "Cookies and other site data" or "Site data" includes localStorage, so clearing that wipes your expenses. Before clearing site data, export to JSON. If you've already cleared and have no export, the data is unrecoverable — that's the price of 100% local storage.

Why no auto-import from my bank?

Bank scraping requires either a paid aggregator (Plaid, Tink — they upload your credentials) or screen-scraping your bank login, both of which break the local-only promise. If you want auto-import, use Mint / YNAB. If you want to know exactly where every byte of your spend data lives, use this.

Splitting a shared apartment's monthly costs without an app account

You and two flatmates split rent, utilities, and groceries. Log each shared expense as you pay it, tag rent vs other, and at month end read the total off the dashboard. Divide by three and message the number. No shared login, no one app holding everyone's bank info.

A freelancer reconstructing deductible spend at tax time

You forgot to track expenses all year and have a shoebox of receipts. Spend an evening keying each one in with the date and a note like "client lunch" or "domain renewal 18.99". Filter by category, read the transport and dining totals, and hand those four numbers to your accountant. Then Export JSON so next year you start from a ledger.

A student on a 1500-a-month budget catching overspend early

Your loan disburses 1500 a month. Log every coffee and bus fare for two weeks, then check the dashboard: dining is already 280 and it's only the 14th. The +/- vs last month tells you you're trending 40 over. You cut takeout before the month, not after the overdraft.

Tracking a two-week trip's spend across four currencies

You're traveling through three countries. Log a 12 EUR lunch, a 40 GBP train, a 200 CNY hotel as you go, each in its own currency. The travel category total shows where the money actually went, and the JSON export becomes your record for splitting costs with a travel partner later.

What this tool does

Free personal expense tracker that lives 100% inside your browser — no sign-up, no upload, no analytics on your numbers. Log a spend in three taps (amount → category → date), pick from 9 preset categories with icons and colors (dining, transport, shopping, entertainment, rent, medical, education, travel, other), in four currencies (¥ CNY, $ USD, € EUR, £ GBP). The dashboard shows this-month total, a per-category bar chart rendered in pure CSS (no chart library), the +/- % change versus last month, and your average daily spend. Every expense is stored in your browser's localStorage under the key `toolora_expenses`; you can export the full ledger to JSON anytime for backup or import it on another device. Built for people who hate handing their bank statements to a free app.

Common pitfalls

Logging only big purchases and skipping the 4 coffees: the small recurring spend is usually where a budget quietly leaks, so log everything, even a 1.50 bus fare.
Clearing "Cookies and site data" in browser settings before exporting wipes localStorage and your whole ledger. Always click Export JSON first, then clear.
Dumping everything into "Other" because picking a category feels slow means that after a month your chart is one giant bar that tells you nothing. Tag dining as dining, transport as transport.

Privacy

Every amount, category, date, and note you enter is written only to your browser's localStorage under the key toolora_expenses. Nothing is sent to a server, and none of your numbers go into the URL or any share link. The only way your data leaves this device is when you click Export JSON yourself.
