Privacy Policy
The short version
Your inventory stays on your iPhone. Kantro has no accounts, no ads, no analytics trackers, and we never see your products, photos or numbers. The only data that leaves your device is what Apple and our subscription processor need to handle a purchase — and it doesn’t identify you personally.
Data we do not collect
We do not collect your name, email address, location, contacts or advertising identifiers. There is no account or sign-up. We do not use third-party analytics or advertising SDKs, and we cannot see or access your inventory data.
Data stored on your device
Products, photos, SKUs, barcodes, quantities, prices, locations, notes and stock movement history are stored in a local database on your device only. This data is included in your device backups according to your iOS backup settings and never reaches our servers — we don’t operate any.
Purchases and subscriptions
Payments are processed by Apple; we never see your payment details. To manage Kantro Pro subscriptions we use RevenueCat, which receives purchase receipt and transaction information tied to an anonymous, randomly generated identifier — not your name, email or Apple ID. RevenueCat processes this data on our behalf to know whether Pro is active. See RevenueCat’s privacy policy at revenuecat.com/privacy for details.
Camera and photo library
Kantro asks for camera access only to scan barcodes and take product photos, and photo library access only to attach photos you choose. Images are processed on your device and stored locally with your inventory. Nothing is uploaded.
CSV export
Exporting a CSV is entirely user-initiated. The file is created on your device and only leaves it if you choose to save or share it. Where you send it is under your control.
Data retention and deletion
Your data stays on your device until you delete it. You can delete individual products, use “Delete all local data” in Settings, or remove everything by deleting the app. Because we hold no copies, deletion on your device is final. Subscription records held by Apple and RevenueCat follow their own retention policies.
Your privacy rights
Depending on where you live — for example under the GDPR in the EU, the UK GDPR, PIPEDA in Canada or the KVKK in Türkiye — you may have rights to access, correct, delete, restrict or port personal data, and to object to processing. Because your inventory never leaves your device, you exercise most of these rights directly in the app: edit or delete products, export a CSV, or use “Delete all local data”. For the limited purchase data processed through Apple and RevenueCat, our legal basis is the performance of your subscription contract; contact us at the address below to exercise your rights over it. You also have the right to complain to your local data protection authority.
Children
Kantro is a business and household utility and is not directed at children under 13. We do not knowingly collect personal information from anyone, including children.
Changes to this policy
If our data practices change — for example if we ever add optional sync — we will update this policy in the app, update the date above, and clearly explain what changed before any new data leaves your device.
