About this app

Nothing good gets typed after 8pm.

Not the message to your ex. Not the post. Not the basket you fill at midnight and pay full price for. Not the email to your boss that reads very differently at nine the next morning.

Dont You Do It shuts the apps you picked in daylight, every night from 8pm to 8am. It does not hide them or grey them out. They do not open.

WHEN YOU TRY ANYWAY

A shield lands in front of the app, carrying a sentence you wrote about yourself while sober. From there you have three ways to go, and none of them is a button that says unlock.

Put it in the vault. Write the whole thing. Hit send. Nobody receives anything, and you cannot read it back until 8am. In the morning you decide: destroy it, or write today's version and send that yourself. Deleting it is the app working.

Answer the ten. Ten real questions about what you are doing and why, and they get harder the more you push. Finish them and one app opens for ten minutes.

Or ring someone. One button, one person you chose in daylight, because the honest answer at 2am is usually a phone call and not an app.

IN THE MORNING

A plain account of the night. How many times you tried. What you wrote. What never went anywhere. And if your phone killed the shield at 3am, the report says so, with the minutes. That number makes us look bad some nights. It is in there anyway, because an app that lies to you about this is not worth having.

WHAT IT COSTS

Free for one app, and the free tier is the entire night: the shield, the vault, the ten questions, the friend button, the morning report. Paying covers every app on the phone and adds the daylight extras, your full history and the money ledger. Monthly, yearly, or once, and once means once.

Every plan is identical after 8pm. Paying widens what is covered. It never changes what happens at 2am, and nothing is ever sold to you while the shield is up.

WHAT IT CANNOT DO

Delete the app, or take a permission away, and the shield stops. Android gives no consumer app a way to prevent that, and anything claiming otherwise is describing something it cannot do.

It cannot stop a reply sent straight from a notification. Nothing running on a phone can see that happen. The app shows you how to switch those replies off.

It does not block websites. It can shield every browser on the phone, which is a different promise, and the one we can keep.

PRIVACY

No account. No sign-up. No server. No analytics. The app has no internet permission at all, and you can check that yourself in Android's own app info in about fifteen seconds. What you write, who you picked and every number in the app sit in your phone's storage and nowhere else. We could not read them if we wanted to.

WHAT IT NEEDS, AND WHY

Usage access, to see which app just came to the front. It cannot see your screen or what you type.
Display over other apps, to draw the shield on top.
Battery exemption, so your phone does not quietly kill the shield at 3am.
Exact alarms, so the night starts on the minute rather than whenever Android gets round to it.

No accessibility service. No VPN. Both are common in this category, and both would see far more than this app has any business seeing.

Built in Estonia. 8pm to 8am, every night, until you say otherwise.
Nothing good gets typed after 8pm. The apps you choose stay shut until 8am.
