How Jambu works

It observes context, then cares — quietly.

01

Observe

Active sessions, inactivity, and session length — signals only. Nothing you type or read is seen.

02

Understand

Over days, Jambu maps your real rhythm — when you focus, when you stall, when you're done.

03

Care

A timely, minimal nudge — a stretch, a break, or a quiet “you're done for now.” No guilt, ever.

A typical workday

Three moments, start to finish

Tall bars are sessions, flat ones are idle time. No page, no title, no text.

Observed

notes.example active since 09:04 · no idle since you started

Understood

Your weekday deep-work window opens around 09:00. You're in it.

Care

Nothing. No nudge is the right care moment here — Jambu stays quiet.

Never stored: the document title, the words you typed, the tab you were just on.

How Jambu compares

The difference is what gets watched.

A lot of software calls itself a productivity helper. The gap between most of it and Jambu is not polish — it is how wide a net the tool casts, and who gets to look.

What it watches

Common in monitoring and timesheet suitesOften the screen itself: screenshots, window or document titles, sometimes keystroke and mouse activity.
JambuTime, idle state, session length and the domain you are on. Not the page, not the text.

Who can see it

Common in monitoring and timesheet suitesUsually a dashboard someone else can open — a manager, a client, an account holder.
JambuYou. Jambu has no manager view to switch on, and no team report to send.

What it builds

Common in monitoring and timesheet suitesA score, a timesheet, a record that can be reviewed and judged later.
JambuA read on your own rhythm, used only to decide when a nudge would help.

How it speaks

Common in monitoring and timesheet suitesFrequently with flags, warnings, streaks or low-productivity notices.
JambuOne line and two choices — take it or snooze it — then it goes quiet.

Who it answers to

Common in monitoring and timesheet suitesWhoever holds the licence, which is often not the person being tracked.
JambuYou, and only you.

When you stop

Common in monitoring and timesheet suitesOften a decision made above you, sometimes discovered after the fact.
JambuWhenever you like: pause, snooze, export your data, delete your history, delete your account.

The left-hand column describes a category, not any particular product. Tools differ a great deal — most do some of these and not others — so read the policy of the tool you are actually using.

Jambu is not invisible either. Your account and the domains you visit are stored in a Supabase database, with the API on Render. What it does not hold is what you read or write: no page contents, no keystrokes, no screenshots.

Questions

The things people ask first.

Short answers, and the same words the privacy policy uses.

Four things: whether a tab is active, when you go idle, how long a session runs, and the domain you are on. It keeps the active domain rather than the full address, so the shape of your day is visible and the pages themselves are not.

No. Page contents, keystrokes, form inputs, passwords, private messages, screenshots and clipboard contents are not collected at all.

It works from the first day, and gets closer over the next week or two as the same patterns repeat. Where it is unsure, it stays quiet rather than guessing.

In a Supabase database, with the API running on Render. That is why Jambu does not claim that nothing ever leaves your browser — it claims only that what leaves is time, idle state, session length and the domain.

Yes. Pause or snooze at any time, adjust your preferences, export your data, delete your activity history, or delete your account and the data that goes with it.
