Stub is an iOS app that tracks warranties, bills, and receipts strictly on-device. Your privacy is our priority.
All data, including photos, PDFs, and text extracted from them (such as dates, vendors, and amounts), is processed and stored locally on your device. We do not transmit, collect, or store your data on our servers or any third-party servers.
Stub operates entirely offline. It makes no network calls. Data extraction (OCR) is performed entirely on-device using Apple's Vision framework.
Your data remains private and on your device unless you explicitly choose to share an image or PDF using the iOS system share sheet.
We may update our Privacy Policy from time to time. Any changes will be reflected in this document.
