Set a weekly frequency. Missed days stay visible; your progress stays yours.

RAISE THE STANDARD TOGETHER

Good company. Serious work.

Open leaderboard

Real accounts. Timer-recorded focus only.

Only completed, server-timed focus counts. Manual/imported time stays in personal analytics. A running timer does not prove learning.

YOUR WORKSPACE

Keep your edge.

Save your study log and interview practice online, then sign in on another device. Use a unique password and keep it safe: email recovery is not available. See Data & privacy for storage details.

Your profile

Shares your display name, username, timer-recorded focus total and current focus status. Session notes and tasks stay private. Private room members see each other’s ranking even when this is off.

Build your study room.

Anyone with the invite code can join this private room. Share the code with people you want in your group.

Bring your work back.

Merge sessions, tasks, deadlines and habits from an ARC backup. Existing records are kept. Imported hours do not earn leaderboard credit.

Your data. Your record.

ARC stores your workspace securely on Cloudflare. Guest workspaces belong to this browser and expire after 30 days without a visit. Create an account to keep your work and use it across devices. Each account has its own sessions, goals, tasks and habits. Passwords are hashed, and private room content is restricted to room members.

Export a JSON backup to keep a portable copy, including interview answers and daily reflections. These stay private to your account and are not shown on leaderboards or in rooms. CSV includes study sessions. Signing out returns you to this browser’s separate guest workspace. Clearing cookies can make guest work inaccessible. Export a backup or create an account first.

Timer duration is calculated on the server. Use Pause when you stop working. Closing the page or putting the Mac to sleep does not pause a running timer, and a sound cannot play while the Mac sleeps.

The open leaderboard includes accounts that choose to participate. Your answers, reflections and notes stay private; room messages are shared with room members. Essential cookies keep your guest workspace and sign-in. Cloudflare hosts and processes the data for Einar Storvestre. No advertising trackers, AI calls or password-reset emails are used. Export a backup at any time; account deletion is available under Your profile.

CLOSE THE DAY WITH INTENTION

How did today go?

The prompt appears when the clock starts. Your answer is autosaved. At the deadline, it locks and the worked solution becomes available. This is a practice timer; no company timing requirement is implied.

Delete your account?

This permanently removes your study records, interview answers, profile and room messages. Export a JSON backup first if you want to keep your work.
