NFC Tag Writer (package com.digitalshijil.nfctagwriter) is published by Digital Shijil LLC (“we”, “us”). This page explains what the app does with information.
We do not collect your personal information, we do not run a server for this app, and we do not show ads. The app has no account and no sign-in. What you write to a tag, and what you read from one, stays on your phone.
We never receive any of this. Android may copy the history, the templates and the settings to your own Google account as part of the normal phone backup if you have that turned on. That is controlled by you and Google, not by us. The purchase hint is never part of that backup.
Writing a tag puts the message on the chip. Anyone who touches the tag with a phone can read it, including a Wi-Fi password or a phone number, so write only what you are happy for them to read. A locked tag cannot be changed again by anyone. The app asks you to confirm before it writes and again before it locks.
Reading a tag shows its type, memory, lock state and contents on your screen. Reading does not change the tag and the contents are not saved or sent anywhere.
The app contains no advertising software, no analytics software and no crash-reporting software from us or from third parties.
Pro features are bought through Google Play Billing. Google handles your payment details and purchase history under Google's Privacy Policy; we never see your card or account details. The app asks Google Play whether a Pro purchase is active on your account. Google Play Billing also sends diagnostic information (for example, error and performance information about the purchase flow) to Google. In the Google Play Data safety form we therefore declare: App info and performance, Diagnostics: collected, not shared, required. The app itself makes no other network requests.
Pro is a yearly subscription with a free trial, or a one-time lifetime purchase. You can manage or cancel a subscription in Google Play.
Export my data (Settings) saves your history and templates as one CSV file in a place you choose. The app does not upload it.
Delete all data (Settings) erases the history, the templates, the settings and cached files, then restarts the app. Tags you already wrote stay as they are. Uninstalling the app also removes everything it holds. A Pro purchase belongs to your Google account and is not affected.
| Permission | Why |
|---|---|
| NFC | To read and write tags. The app uses NFC only while a screen is waiting for a tag. |
| Billing and network state | Declared by Google's Play Billing and In-App Review libraries to show prices, complete a purchase and show the review prompt. |
The app does not ask for your location, contacts, photos, files, microphone, camera or notifications. The list of apps for the Open an app record shows only apps that have a launcher icon, and it is not stored or sent.
The app is built with AndroidX, Jetpack Compose and Material 3, Room and DataStore, Kotlin and kotlinx.coroutines (Apache License 2.0) and Google's Play Billing and In-App Review libraries. The list is in the app under Settings, Open-source licenses.
NFC Tag Writer is not directed at children under 13, and we do not knowingly collect information from anyone. It ships no content of its own.
If the app's behaviour changes in a way that affects this policy, we will update this page and the date above before the change ships.
