Sillby Privacy Policy

Last updated: 10 September 2026 ยท Applies to the Sillby Android app (com.ncrwp.sillby)

The short version. Sillby has no internet permission. It cannot open a network connection, so nothing it reads or stores can be sent anywhere. There are no accounts, no servers, no analytics, no advertising and no third-party SDKs.

You can verify this yourself: open Android Settings โ†’ Apps โ†’ Sillby โ†’ Permissions, or inspect the app's manifest. android.permission.INTERNET is not requested.

Who is responsible

Sillby is developed and published by NCRWP (Neilson Calixto), an independent developer. Questions about this policy or about your data: contact@ncrwp.com.

What Sillby reads

Your notifications

With notification access, Sillby reads the notifications your other apps post: the app they came from, the title, the text, message senders, timestamps, avatars and action buttons. This is what the app exists to show you on your lock screen. Reading happens entirely on your device.

The list of apps installed on your phone

Sillby queries which apps can be launched (QUERY_ALL_PACKAGES) for one purpose: to show you a list you can pick from when choosing which apps to exclude, filter or group. The list is never stored beyond the current screen and never leaves your device.

Accessibility service

Sillby uses Android's Accessibility Service API for a single technical reason: it is the only supported way to draw its tab and panel on top of the lock screen. It does not read screen content. While your phone is locked, Sillby is told which app has come to the front, so it can hide its tab in the apps you choose: that name is held in memory only and never leaves your device.

Connection status

The optional Phone status page reads whether you are connected to Wi-Fi or mobile data, the signal level, and whether NFC is on. These are read-only checks of your device's own state. Sillby does not use them to connect to anything, because it cannot.

What Sillby does not read

What Sillby stores, and for how long

Uninstalling Sillby deletes all of it from your phone.

What leaves your device

Sillby itself sends nothing. It has no network access. The only way any of this data can leave your phone is through Android's own backup system, which belongs to you and to Google, not to Sillby:

What Sillby never does

Your controls

Children

Sillby is a general-purpose utility and is not directed at children under 13. It collects no personal information from anyone, including children.

About this website

This policy covers the Android app. The website itself uses privacy-friendly analytics with no cookies and no persistent identifier: page views, and which site or search brought you here. Nothing is stored on your device, and nothing is shared with advertisers.

Contact

Questions, corrections, or a data request of any kind: contact@ncrwp.com. Since Sillby holds nothing about you on any server, there is nothing for the developer to look up, export or delete on your behalf; everything is on your phone and under your control.
