Reference Pin · 1UP PixelWorks · Last updated: July 4, 2026

1UP PixelWorks (“we”, “us”) operates the Android app Reference Pin (the “App”). This page explains what data the App handles and how.

Summary

Reference Pin is designed to keep your data on your own device. The App does not have a server, does not require an account, and does not send the images, PDFs, notes, or checklists you pin to us or to any third party.

Data the App stores

  • Pinned content — images, PDFs, notes, and checklists you add are copied into the App's private storage on your device and never leave it.
  • App settings — window position/size, opacity, and your Pro entitlement status are stored locally on your device.

If you use Android's built-in backup feature, this local data may be included in the backup Android takes to your own Google Account, exactly like any other app's local data. We do not have access to it.

Permissions the App requests, and why

PermissionPurpose
Display over other appsRequired for the core feature: showing your pinned reference as a floating window on top of other apps.
Foreground serviceKeeps the floating window running reliably while you use other apps.
NotificationsShows an ongoing notification with a “hide all” control while a pin is on screen, as required by Android for foreground services.
BillingUsed to process optional Pro purchases via Google Play Billing (see below).

The App does not request access to your camera, microphone, contacts, or location.

Purchases

Optional Pro subscriptions and one-time purchases are processed entirely by Google Play Billing. We do not receive or store your payment card details. Google's handling of that data is governed by Google's Privacy Policy. We only receive a purchase/subscription status token used to unlock Pro features.

Analytics and advertising

The App does not currently include any analytics, advertising, or tracking SDK.

Children's privacy

Reference Pin is a general-purpose productivity tool not directed at children under 13, and we do not knowingly collect data from children.

Data deletion

Because your pinned content and settings are stored only on your device, uninstalling the App removes all of it. There is no server-side account or data for us to delete.

Changes to this policy

If this policy changes (for example, if a future version adds optional cloud sync), we will update this page and change the “Last updated” date above.
