Half Price ("the app", "we") helps you track grocery prices at Woolworths and Coles. We designed it to collect as little as possible: no account, no name, no email, no location, no advertising trackers.

## What we collect

| Data | What it is | Why |

|---|---|---|

| Anonymous device ID | A random identifier created when you first open the app | Keeps your tracked staples and savings ledger together without an account |

| Device credential | A secret token issued to your install (we store only a cryptographic hash of it) | Ensures only your device can read or change your data |

| Push notification token (optional) | An Expo push token, only if you allow notifications | Sends your Wednesday specials digest |

| Tracked staples | The products you choose to follow | The core function of the app |

| Savings ledger | Your "stocked up" taps: product, price, savings amount, date | Shows your running savings total |

None of this identifies you personally. We do not collect your name, email address, phone number, precise location, contacts, photos, health data, or payment details. Grocery price data shown in the app is public retailer pricing, not personal data.

## What we don't do

• We do not* sell your data, and we do not share it with anyone for advertising.
• We do not* use third-party advertising or analytics SDKs.
• We do not* track your location or your movements between stores.
• We do not* link your data to your identity — we couldn't; we never learn it.

## Service providers

Your data is processed by infrastructure providers acting on our instructions:

• Railway* — hosts our backend server and database.
• Expo* — delivers push notifications (receives only your push token and the notification content), if you enable them.
