Privacy Policy
Overview
Yield is an offline-first Android application. It does not connect to the internet, does not collect personal information, and does not transmit any data to external servers or third parties. All data you create in Yield stays on your device.
Information We Collect
Yield does not collect any personal information. The app stores the following data locally on your device, in a private application folder:
- Item records (name, source, status, listing and sale details, notes)
- Item types and pricing settings you define
- Cost entries you add to items (category, amount, notes)
- Selling-platform entries and their fee settings
- Price-change history and listing details
- Photos you attach to your items
- App settings and preferences
None of this data is linked to your identity, uploaded anywhere, or shared with any third party.
How We Use Your Data
Data stored by Yield is used solely to operate the app's features on your device:
- Displaying and organizing your inventory across its prospect, inventory, and sold stages
- Calculating pricing estimates, platform fees, and return margins
- Showing insights such as profit, ROI, sell-through, and average time to sell
- Restoring app state between sessions
Photos & Camera
Yield lets you attach photos to your items. When you choose to add a photo, the app asks for permission to use your camera or to select images from your photo library. Selected images are resized and saved into Yield's private application folder on your device. Photos are never uploaded or shared by the app — they are only included if you choose to export your data (see below). Yield only accesses your camera or photo library at the moment you add a photo.
Export & Import
Yield includes an optional export feature. You can export your full ledger (your data.json plus your item photos) as a ZIP file, or export your item list as a CSV file, through Android's standard share sheet (expo-sharing). Import is handled through Android's system file picker (expo-document-picker / Storage Access Framework). Neither process routes data through any server — all file operations are local and on-device. You choose what you do with exported files.
Permissions Required
Yield requests only the permissions needed for features you actively use:
- Camera — used only when you choose to take a photo of an item
- Photos / Media — used only when you choose to attach an existing image to an item
- Storage Access Framework — used for the optional import and export features. This does not require a broad storage permission; Android manages file access through the system file picker and share sheet
Yield does not request access to your contacts, location, microphone, or any other sensitive system resource.
Data Storage & Security
All app data is stored in a private application folder that belongs to Yield and is not accessible to other apps. This data is removed when you uninstall Yield. If you have Android's built-in backup enabled, your device OS may back up app data to your Google account; this is governed by Google's privacy policy, not ours.
Data Sharing
Yield does not share any data with third parties. There are no analytics SDKs, crash reporting services, advertising networks, or external APIs integrated into the app.
Deleting Your Data
You can delete all data stored by Yield at any time by clearing the app's data in your Android settings (Settings → Apps → Yield → Storage → Clear Data), or by uninstalling the app.
Children's Privacy
Yield does not knowingly collect any information from children. The app collects no personal information from any user, regardless of age.
Changes to This Policy
If this privacy policy changes, the updated version will be published at this URL with a revised effective date. Continued use of Yield after any changes constitutes acceptance of the updated policy.
