## What is Arc Lock?

Arc Lock blocks the apps and websites that eat your day, and once a block starts, it stays on.

Most blockers keep their "hard mode" behind a subscription. Arc Lock is free: no account, no ads, no in-app purchases.

SCHEDULES
Pick apps, app categories and websites, choose the hours and days, and they lock on their own. Overnight windows like 11 PM – 7 AM work too (up to 22 hours).

DAILY LIMITS
Allow yourself a set time each day, from 5 minutes to 8 hours. See exactly how many minutes are used and left today. When the time is used up, those apps lock until midnight. A heads-up comes 5 minutes before.

TIME-OUTS
Not a full block, a pause. After a stretch of use, the apps take a short break, then open again. For example: after 20 minutes of short videos, a 10-minute break. It repeats all day.

BLOCK NOW
Lock distractions right away, from 15 minutes to 12 hours.

STRICT LOCK
Every block can have Strict lock, and it's on by default. While a strict block runs:
• it can't be stopped, loosened or deleted in Arc Lock
• the date and time can't be changed by hand
• the block screen has a single button: Close
Daily limits and time-outs are locked in for the day: you can make them stricter once a day, but looser settings only count from tomorrow.
Want a gentler block? Switch Strict lock off for that block, and you can stop it whenever you like.

DELETION PROTECTION
On by default: no app can be deleted from your iPhone, Arc Lock included. Switching it off takes effect at midnight.

LOCK-IN
Freeze every rule for 1 to 30 days, even between blocks: no loosening, no deleting rules, no deleting apps. Changes you queued before it wait until it ends.

WEBSITES BY ADDRESS
Type a site like youtube.com and it's blocked in Safari and every other browser, in schedules, daily limits, time-outs and Block now.

THEMES
Five themes (Navy, Graphite, Forest, Plum and Paper), each with a matching app icon. The phone-and-lock mark in the app closes while something is blocked.

PRIVATE BY DESIGN
Arc Lock works through Apple's Screen Time. Apple keeps your activity on your iPhone; Arc Lock never learns which apps you use and sends nothing anywhere. No account, no analytics, no tracking.

OPEN SOURCE
The complete source code is on GitHub under the MIT license: github.com/WeldingArc/arc-lock
