Are you seriously using Simeji? But it turns out that it is the strongest secure Japanese input method.

"Huh, you use Simeji?" "Doesn't that mean the input data is sent to China...?"

Yes, we understand that concern. Indeed, if you install Simeji on a typical smartphone and use it without any settings, it is designed to connect to the cloud and perform analysis to improve predictive conversion accuracy.

But here comes our AntiSpyPhone.

AntiSpyPhone features the ability to fully customize detailed access permissions for each app.
Neither the camera, microphone, nor network can be used by the app unless permission is granted.
In other words, it is even possible to "use Simeji without granting any network access."

So why bother with Simeji?

The reason is simple. Its Japanese conversion accuracy is incredibly high. Complex conversion apps or offline-only input methods (e.g., Alte Japanese Input) are indeed supported by security-conscious users.
However, those tend to cause some stress in daily use.
Predictive conversion may be mediocre, or correcting mis-conversions can be cumbersome.

Simeji offers high conversion efficiency and smooth input.
Yet, by completely blocking network access with AntiSpyPhone, it meets the greedy demand of "I want both security and ease of use!"

Of course, this is almost impossible on a normal Android device

If you install Simeji via Google Play, cloud prediction almost certainly operates.
Even if you try to stop it, communication may secretly occur in the background.
However, with AntiSpyPhone combined with the Vanadium browser and offline firewall, you can truly reduce communication to zero.

For example, the following settings are sufficient.

Do not grant "Internet access" permission to Simeji
Disable all such as "notifications," "battery optimization," and "sensor access"
Monitor post-launch communication with AntiSpyPhone's "Permission Manager"

This shuts out cloud prediction and ads.
Though cute in appearance, the inside becomes an ultra-secure Japanese input environment.

In other words, "a Simeji you can use with peace of mind" is achievable with AntiSpyPhone.
Maintaining a casual UI and smooth conversion while completely blocking network access.
Isn't that exactly a "smart way to use" positioned between security enthusiasts and general users?

Of course, hardcore users might say, "No, I'm an Alte fan." But I dare say this.

"Security is not 'zero risk.' It's 'how to deal with risk.'"

AntiSpyPhone is a smartphone that frees that choice.
That's why you can train and use "commonly used daily apps" like Simeji in a super secure way.

How about this secret trick where Simeji, which you used to think was "somehow scary," actually becomes your best ally?
