Trac is a time tracker for freelancers that runs entirely in your browser. See where your time went, hit your goals, and turn tracked hours into invoices — without ever handing your work to someone else's server.
Works offline · Installs as an app · Free forever for up to 3 projects

Everything, nothing extra
One tab open, a timer running, and a clean answer at the end of the month about where your hours went and what they're worth.
Pick a task, hit start. A running strip keeps the clock in view no matter which tab you're on.
Hours, billable totals, days worked and a weekly trend — filtered by client, project or tag.
Roll tracked hours into a numbered, taxed, print-ready invoice. Billed time is marked so you never double-bill.
Set daily and weekly hour targets. A day off never breaks your streak — only a day you fell short does.
One-click JSON backups, CSV export for billing, and optional folder sync to OneDrive or Dropbox.
Crash recovery for a timer left running, break reminders, and a nudge if you forget to stop the clock.
Track
No projects to configure before you can begin. Type what you're doing, start the timer, and sort it out later. Today's entries group by project so the day reads at a glance.

Invoice
Bill by project or by client, pick a period, and Trac builds the line items for you. Round to 6, 15 or 30-minute increments, add tax and terms, then print to PDF.

Open the page and start. Nothing to sign up for, no email, no password.
Every entry lives in your browser's local storage. There is no server to breach.
Export to JSON or CSV whenever you like. Your history is never held hostage.
Pricing
No subscriptions. Start free, and upgrade only when you outgrow it.
Questions
Entirely in your browser, using IndexedDB. Trac has no server-side database and no account system — nothing you track is ever uploaded. That also means keeping your own backup matters, which is why one-click export and optional folder sync are built in.
Yes. The free tier covers up to 3 projects with 90 days of history — enough to run a small freelance practice indefinitely. Premium is a one-time $19 unlock, not a subscription.
Yes. Trac is a Progressive Web App — install it from your browser and it runs offline like a native app, timers and all.
Export a JSON backup on the old machine and restore it on the new one. Premium's folder sync can also keep a live copy in OneDrive or Dropbox that any device can restore from.
No sign-up, no download, no credit card. Open Trac and start tracking.
