Convency · A Chrome extension for deep work

Know where your day goes.

Convency hides page distractions, tracks screen time and data usage, caps your rabbit holes, and sends you on Mario breaks — from one quiet popup.

Everything stays on your device — no cloud, no login, no ads.

Everything in one tab

Six quiet superpowers.

No dashboard to manage. No account to create. Just a popup that does its job.

Focus mode

Hide page distractions and read without the sidebar begging for your attention.

Screen time

Today, week, month, year — with per-site breakdowns and an activity heatmap.

Data usage

See exactly what every site downloaded — per hour, per day, per domain.

Site limits

Set a daily cap per site. When you hit it, Convency closes the tab and says so.

Mario breaks

Pomodoro rests with a Super Mario twist — complete with a tic-tac-toe round.

Clean history

Wipe browsing history and cookies with one click, or back everything up first.

The student

Read a paper without the tabs calling to you. Set a 30-minute cap on the feed and keep going.

The developer

See how much of the day GitHub and Stack Overflow actually take. The data view tells the truth.

The 9-to-5

Browsing “for research” has a number now. Share your weekly report — or keep it to yourself.

Questions

Asked, answered.

The short version of everything people ask before installing.

Does it upload my browsing data anywhere?

No. Everything lives in chrome.storage on your device. There is no account, no server, and no analytics — Convency never phones home.

Will it slow down my browser?

It only wakes up when a tab changes, then sleeps. It tracks page activity and downloads in the background without touching your page's performance.

What counts as "screen time"?

Time spent in an active tab for each site you visit, rolled up per day, week, month, and year. The activity heatmap shows exactly which hours you work.

How does data usage get measured?

Every response your browser receives is attributed to the site that served it — so video and downloads show up exactly where the megabytes came from.

Do site limits actually close the tab?

Yes. When a site hits its daily cap, Convency closes it and tells you. Pause the cap for the day when a real deadline shows up.

What happens to my history when I clear it?

One click wipes browsing history, cookies, and downloads. Worried? Back everything up to a JSON file first and restore it later.

Give your rabbit holes a gate.

Two minutes to install. A quieter day after that.
