Price Trail

Price Trail watches product prices so you don't have to. It is designed to collect and share nothing about you.

Summary in one line: Price Trail collects no personal data, has no accounts, no ads, no analytics, and no tracking. Your product list and price history stay on your devices and in your own private iCloud.

What the app stores

The product links you paste, and the names, photos, and prices found on those pages.
The price history the app records over time, your target prices, and alert settings.

All of it lives in the app's local database on your device and — so your iPhone and iPad stay in sync — in your private iCloud database, which Apple encrypts and which we cannot read or access.

Network requests

The app talks only to the store pages you add, over HTTPS, to read the public product page — the same request your browser would make. There is no server of ours in the middle, no proxy, and no third-party service.

The price outlook

The "outlook" estimate (whether a price looks likely to drop) is computed entirely on your device from that product's own tracked history. Your shopping list is never sent to any AI service.

What the app does not do

No accounts, sign-ups, or email collection.
No analytics or crash-reporting SDKs.
No advertising and no ad identifiers.
No selling or sharing of data — there is nothing to sell.

Notifications

Price-drop alerts are local notifications generated on your device. They are optional and controlled in Settings.

Deleting your data

Delete a product to remove its history, or delete the app to remove everything on the device. iCloud data can be removed in Settings > Apple ID > iCloud > Manage Storage.
