What runs in the background while you are not looking

You leave the app open for hours, maybe days. This article lists everything Booked Solid OS does on its own during that time, so nothing feels mysterious - and confirms what it never does.

The full list of background work

While the app is open, four kinds of quiet work happen:

• Scheduled tasks. A scheduler wakes every 30 seconds and checks whether one of your scheduled tasks is due. Tasks run strictly one at a time - if the engine is busy with another job, a due task waits its turn. If your laptop was asleep at task time, the task runs when the computer wakes, because a task is due once the clock has reached its time.
• Account check. The app confirms your subscription with the account service at launch (with one retry 30 minutes later if the service is unreachable) and then every 6 hours while it runs. If the server is down or unreachable, nothing changes on your machine - your offline grace covers it. Only an explicit denial from the account service changes your signed-in state.
• Watch folders. If you set up watch folders, the app watches them for new or changed files and copies them into your workspace inbox/ with collision-safe names. It waits for a file to finish writing before copying, so half-downloaded files never arrive. The original file is never moved or touched, and every arrival is logged to inbox/inbox-log.md.
• Update check. A quiet check for a new version happens at every launch of the installed app. Updates replace only the app itself - your Booking HQ, settings, and saved keys are untouched.

There is also some housekeeping you will never notice: index statistics run on a separate worker thread so the interface never freezes while you type. Scheduled backups run without needing the AI engine at all.

Nothing runs when the app is closed

All of the above happens only while Booked Solid OS is open. Quit the app and everything stops - no hidden service keeps working, no task fires overnight on a closed laptop. When you open the app again, any scheduled task whose time has passed runs then, because the clock has reached its time.

How you hear about background results

Notifications are deliberately quiet. The app uses your operating system's normal notifications for only two kinds of messages: something finished ("done") or something needs your attention ("needs you"). There is no notification history inside the app and no custom sound system. One exception exists: on a computer without a secure keyring, a one-time notice explains how your sign-in is stored.

Good to know

• Editing a schedule applies at the next 30-second tick - no restart needed, because the scheduler reads your settings fresh every time.
• The 6-hour account check never keeps the app alive on its own, and a server outage never signs you out.
• A watch folder that is disabled or whose folder is missing is silently skipped - nothing breaks.
