Privacy policy

This policy explains how Stowyn (“we,” “us,” “our”) handles your information in the Stowyn app (the “App”).

What stays on your device

The App stores this on your device only:

• Pantry items, quantities, expiry dates, notes, and barcodes;
• Grocery lists, stores, budgets, prices, and purchase history;
• Categories, units, and preferences;
• Product and store photos you add;
• Notification and app settings;
• Your local purchase (Pro) status cache.

We do not upload this to any server. It stays on your device until you export or share it, use a feature that needs an outside service, reset the App, or delete it. If you enable them, reminders for expiring, expired or low-stock items are built from this data on your device; we do not send marketing push notifications.

What leaves your device

The App sends us nothing about your pantry, groceries, receipts, or prices. There is no analytics and no usage tracking of any kind. Left to itself, the App makes only two kinds of network call: purchase verification through RevenueCat and update checks through Expo. Both carry an anonymous app ID and the app version, and neither carries your content. The features you choose to use, such as barcode lookups, voice entry, and sending feedback, are described in the sections below.

Camera, microphone, and scanning

With your permission, the App uses the camera to scan barcodes and shelf tags and to take product photos, or you can pick a photo from your library. Images and shelf-tag text are read on your device. We do not record video or send your camera images to us.

When you scan a barcode, only the barcode number goes to Open Food Facts (and its related Open Products and Open Pet Food Facts databases) to look up public product details. As with any web request, that also shares your IP address and app user-agent.

If you use voice entry, the App uses the microphone and your device’s speech recognition to turn speech into text. Depending on your device and settings, this happens on your device or is sent to Apple, Google, or another speech provider. We never receive or store your audio.

Feedback

The App’s Send feedback option opens a prefilled email to support [at] stowyn.com. It includes only what you write, plus your app version, build, platform, and where in the App you started feedback from. It does not attach your pantry or grocery content, diagnostics, logs, exports, or any device or install identifier. Any contact details you choose to include are used only to reply to you. To request deletion of feedback you sent with contact details, email privacy [at] stowyn.com.

Purchases

The App uses RevenueCat to offer and manage optional subscriptions. RevenueCat and the app store may process an anonymous app-user ID, your purchase and subscription details, entitlement status, and basic app and device information. Payments go through the Apple App Store or Google Play; we never see your full card details.

Exporting and sharing

You can export your data as a backup archive, a .zip file that also contains your product and store photos, or share a receipt image. When you use the system share sheet, the data goes only to the destination you pick, which then handles it under its own privacy terms. The backup file is deleted from temporary storage as soon as the share finishes. A shared receipt image stays in the App’s temporary storage on your device until your device clears it.

Services the App connects to

Depending on the features you use, the App may involve the services below, and only for the purposes given. Each handles data under its own privacy policy.

• Open Food Facts and related Open Facts databases, for barcode lookups;
• RevenueCat, for purchases;
• Expo, for app updates. Expo and your internet provider may process basic request information (IP address, app version, platform, and device or install details) needed to deliver and secure them;
• Apple and Google, for app distribution and payments, and Apple, Google, or whichever speech provider your device uses, for speech recognition.

Keeping and deleting data

Your data stays on your device until you delete individual records or use Settings → Reset app data. Photos are kept with the product or store they belong to, and Reset app data clears them. To remove everything, clear the App’s storage in your device settings or delete the App. Files you exported stay wherever you saved them.

Data held by an outside service is kept under that service’s own policy. To ask about it or make a request, email privacy [at] stowyn.com; we may need details from your device or purchase record to find the right anonymous record.

We limit data handling to what the App needs and rely on your operating system to protect on-device data. Network requests use HTTPS. No system is perfectly secure, so we cannot guarantee absolute security.

Children

Stowyn is for a general audience and is not directed to children under 13 (or the minimum age in your country), and is not intended for use by children without a parent or guardian. We do not knowingly collect children’s personal information. If you believe a child provided information through a service the App uses, contact us and we will look into it.

Your rights

Because your data lives on your device, you control most of it directly: view, edit, export, and delete it in the App. Depending on where you live (for example, the EEA, UK, or California), you may also have rights to access, correct, delete, export, or object to how your personal information is used, and to not be treated differently for using those rights. We do not sell or share your personal information for cross-context advertising. To make a request, email privacy [at] stowyn.com.

Changes and contact

We may update this policy as the App changes, and will update the “Last updated” date above. We may also note significant changes in the App or on the store listing.
