About this app

Pass Lock is a one-time purchase concentration app that gently restricts tempting apps on your smartphone according to time limits, acting on your behalf as you focus on studying to pass exams, tests, and other learning activities. It blocks apps the moment you try to open social media or video apps, protecting your optimal study and memorization time.

——————————————
■ When to Use
——————————————
・You want to stop reaching for your smartphone during the final push for exams, qualifications, or practice tests.
・You want to secure focused work time multiple times a day.
・You want to stop yourself from opening social media without realizing it.
・You don't want to pay for subscriptions. A one-time purchase for life use

——————————————
■ What you can do with the free version
——————————————
◎ Register as many apps to monitor as you like (unlimited number)
◎ Freely set focus time from 5 minutes to a maximum of 12 hours
◎ Freely set reward time from 5 minutes to a maximum of 3 hours
◎ Gently stop the app when it is opened with a blocking screen

The only limitation is that "monitoring can only be activated once a day." Place that one activation at your best timing and use it to its fullest.

——————————————
■ What you can do with Pro (one-time purchase)
——————————————
◎ Activate monitoring multiple times a day—this is the only core value of Pro

90 minutes in the morning, 90 minutes in the afternoon, 60 minutes at night. Freely turn it on/off between studying or working.

It addresses the need for constant protection during exam periods, busy seasons, writing days, and other times when you think, "I need this to stay on all day."
◎ All other functions, such as time settings and app selection, are the same as the free version.

You can judge the value of Pro simply by whether you want to use it again after the first time.

——————————————
■ How it Works
——————————————
◎ Usage Time Ranking
Simply select the app that you're most preoccupied with using the "most frequently used" order.
◎ Blocking Screen
When you open the target app, a "STOP" screen will appear. There is no emergency release button.
◎ Privacy
No screen text, input, or passwords are collected. Accessibility services are used only for "foreground app package name detection."

——————————————
■ About the Use of the AccessibilityService API
——————————————
The core function of this app (detecting the launch of the monitored app) requires the use of Android's accessibility features (AccessibilityService API) to detect only the change in "which app is currently on the screen."
It is not used for screen reading, key input acquisition, or voice recording. Before use, the app will clearly state what it does not intend to do, and you can choose to agree or deny using a button.

——————————————
■ Pricing (All are one-time purchases)
——————————————
• Pro is a one-time purchase; there are no subscriptions. Once purchased, you can use it forever.
• Please check the Pro information within the app for displayed prices and campaigns (contents may change).

——————————————
■ Reasons for No Emergency Deactivation
——————————————
To prevent the focus time from becoming a "place to escape at any time," we intentionally do not offer an emergency deactivation function.

——————————————
■ Frequently Asked Questions
——————————————
Q. Is there a subscription?
A. No. It's a one-time purchase.
Q. How much can I use for free?
A. There is no limit to the number of apps you can monitor, and you can freely set the length of the focus time from 5 minutes to 12 hours. The only limitation is that you can only activate it once a day. If you want to use it more than once, please consider Pro.

Q. What changes with Pro?
A. You will be able to activate monitoring multiple times a day. That is the only core value of Pro. There are no differences in features such as time settings, number of apps, or facial expressions.

Q. What is the accessibility service used for?
A. It is used only to detect the package name of the currently displayed app. It does not retrieve text or input content.

Q. Is an internet connection required?
A. After Pro authentication, all functions can be used offline.
