The guide
The best private time trackers for Mac (2026)
Most time trackers are made by honest people. Still, privacy that depends on a policy is different from privacy that depends on the code. This guide compares five Mac time trackers on three simple questions: where the data lives, what the app can access, and how the business makes money. One of the five, Build Mode, is our own app, and we say so plainly below.
The criteria
Three questions that sort the field quickly.
Where the data lives
Local files on your Mac are private by default. Data synced to a server is private by policy. Both can be fine, but they are different promises, and the difference matters most for work you care about.
What the app can access
Every macOS permission a tracker requests widens what it could see. The fewer permissions it needs, the less you take on trust. Zero permissions means zero new access to grant.
How the business makes money
A paid tool has a simple deal: you are the customer. Free tools can be great too, especially when they are open source. Whatever the model, it should fit in one sentence.
Free and open source
ActivityWatch
ActivityWatch is a free, open source, local-first tracker that records activity automatically and keeps its data on your machine by default. Because the code is open, anyone can read how it works, which is a real privacy advantage. Best for: people who want automatic local tracking at no cost and are happy to configure it themselves.
Manual timer, built for teams
Toggl Track
Toggl Track is a manual start-and-stop timer with cloud sync, reports, and team features, and it offers a free plan. Syncing is the point: entries follow you across devices and power its reports and team features, which means the data lives on Toggl’s servers under its policy. Best for: freelancers billing clients and teams that need shared reporting.
Automatic, Mac native
Timing
Timing is an automatic time tracker built for the Mac and sold as a subscription. Its strength is depth of automation: it aims to reconstruct your day without you starting a timer, and that thoroughness is the reason people pay for it. Best for: Mac users who want detailed automatic records and are comfortable with a subscription.
Automatic, cloud reports
RescueTime
RescueTime tracks automatically, syncs data to its cloud service, and is subscription based. Its strength is the long view: reports and trends that help you understand your habits over months. If you are weighing it against Build Mode specifically, our RescueTime alternative guide goes deeper. Best for: people who want automatic, multi-device insight and are fine with cloud storage.
Our app
Build Mode
Build Mode is our product, so weigh this entry accordingly. It is a one-button tracker for people building something: press ⌘⌥B, a short full-screen ceremony starts the session, a small clock shows in the MacBook notch, and pressing again stops it with a one-line note. It counts active time only, pausing when you step away, and sorts hours into skills on your Mac. No account, no cloud, no networking code at all, zero macOS permissions, $9 once. Best for: solo builders who want privacy enforced by structure and a price paid once.
Full disclosure
Build Mode is ours. Here is the honest frame.
The other four tools are good software, and for many people one of them is the right choice. ActivityWatch wins on price and openness. Toggl Track wins for teams. Timing and RescueTime win on automation depth. We built Build Mode for a narrower person: someone building one thing on one Mac who wants tracking that can’t phone home.
That is not a promise, it is a property. Build Mode contains no networking code at all, which you can check by searching the app for networking symbols, and it asks for zero macOS permissions, so there is nothing to grant and nothing to trust. Your hours, notes, and weekly recaps stay on your Mac.
Read why local-only tracking mattersCommon questions
Short answers about private tracking.
Which of these is free?
ActivityWatch is free and open source, and Toggl Track offers a free plan. Build Mode has no free tier: the download is free, and a $9 one-time license unlocks the app. The founder price rises as early batches sell out; the full ladder is on the pricing page.
Does private tracking mean manual tracking?
Not necessarily. Build Mode’s Auto Mode sorts hours into categories from the name of the frontmost app, entirely on your Mac. Browsers are left unassigned by default, and you can turn Auto Mode off in Settings and pick categories yourself.
How can I check Build Mode’s privacy claims?
You don’t have to take our word for it. The app contains no networking code, which anyone can verify by searching it for networking symbols, and it requests zero macOS permissions. There is no account, no cloud, no screen recording, no keystroke logging, and no website tracking.
What exactly does Build Mode record?
Active time and the categories your hours belong to. Sessions pause when you step away or the display sleeps, so the totals reflect real work. Daily, weekly, and all-time totals build toward long-term hour goals, which is the whole idea behind our deep work tracker guide.
What does Build Mode run on?
macOS 14 or later, on Apple Silicon or Intel. The license key arrives by email, and it is verified on your Mac and never sent anywhere. Terms are at /terms.
Private by structure, not by promise.
