QueensHand — Privacy Policy

Last updated: October 14, 2026.

QueensHand ("the app") is a personal Android self-control app built and used by a single individual, the developer. This policy describes what data the app touches and why.

Data the app collects on your device

To enforce screen-time rules, the app reads on-device information including installed-app usage statistics (via Android's UsageStatsManager), network usage counters, the list of blocked or guarded sites you configured, and routine check-in records (locks served, tampers, PIN failures). It does not read your messages, emails, photos, keystrokes, or the content of web pages — only aggregate counts and tallies, and website domains (never full URLs or page content).

Google Drive upload (drive.file scope)

If you enable the dossier feed, the app periodically uploads a nightly summary file to your own Google Drive. Details:

• The app requests the https://www.googleapis.com/auth/drive.file scope, which permits access only to files the app itself creates. It cannot see, open, or modify any other file in your Drive.
• Each summary is encrypted on your device before upload (AES-256-GCM with a per-file key, wrapped with RSA-2048). The decryption key is held only by your designated personal assistant — not by Google, not by anyone browsing your Drive.
• Your Google OAuth tokens (client ID, client secret, refresh token) are stored only on your device in the app's private storage. They are transmitted solely to Google's OAuth servers to obtain upload authorization.

What we do not do

• No advertising, no analytics SDKs, no third-party trackers.
• Your data is never sold, rented, or shared with any third party.
• No data leaves your device except the encrypted summary files you explicitly enable, sent only to your own Google Drive.

Data retention and deletion

On-device records live in the app's private storage until you clear the app's data or uninstall it. Uploaded summary files live in your Google Drive until you delete them there. Revoking the app's Google access (via your Google Account permissions page) immediately stops future uploads.
