Your shelf, your avoid list and your reminders stay on your device — we can't see them, access them, or share them. Two optional features sync a little data through your own iCloud (see iCloud Sync below), but never your avoid list or any health-related data.

Data Stored Locally

• Items and their expiry dates
• Your avoid list (allergens/ingredients)
• Preferences

All data is encrypted via iOS storage when your device locks.

iCloud Sync (optional)

Two features are off until you turn them on, and use Apple's iCloud so your data follows you across your devices:

• Shared family shopping list — if you start or join a shared list, the grocery items and the display name you choose sync through iCloud so everyone with your household code sees the same list. Only the shopping list is shared — never your avoid list, health data or inventory.
• Your saved recipes — recipes you create are stored in your private iCloud so they appear on all your devices, and stay private to you.

Everything else stays on your device.

What We Do NOT Do

• No accounts
• No tracking
• No ads
• No data monetisation
• No servers of our own
• No selling or sharing your data

Barcode Lookups

When you scan a barcode, Custoda may request public product information from a third-party product database. That request contains only the barcode number — no identity and no account. Results are cached on your device so repeat scans work offline.

Camera

The camera is used only to scan barcodes and read printed dates, entirely on-device. Images are never stored or transmitted.

Payments

All payments are processed by the Apple App Store. No financial details reach Custoda.

Notifications

Expiry reminders are local and device-side. No server is involved.

Deletion

Delete individual items in the app, or uninstall Custoda to remove everything.

Data Sources

Product data comes from Open Food Facts contributors (ODbL). Some medicine data comes from the U.S. National Library of Medicine (NLM); NLM does not endorse this product.

Not Medical Advice

Custoda helps you track expiry and flags ingredients you've told it to avoid. It does not guarantee a product is safe — always check the packaging and consult a pharmacist or doctor.
