Food Storage Calculator: Emergency Food & Water Storage Planner
Last updated: July 8, 2026
Developer: EMSERO LLC

The short version

Food Storage Calculator is built to be private. All of your plans, inventory, and settings are stored locally on your device. We do not run an account system, we do not collect your personal information on our own servers, and we do not use any analytics, advertising, or tracking SDKs. We never sell or share your data.

Local data storage

  • Everything you enter (household size, coverage duration, saved plans, tracked inventory, and reminder settings) is stored locally on your device using Apple's SwiftData framework.
  • If you have iCloud Device Backup enabled at the iOS level, your device's local data (including this app's local data) is included in those backups under Apple's policies. We do not have access to your device data or your iCloud backups.
  • We have no server that stores your plans or inventory.

Subscriptions and purchases

The calculator is free. Pro features (saved plans, inventory tracking, gap analysis, expiration reminders, and PDF export) are available through an in-app purchase: a monthly subscription or a one-time lifetime unlock.

  • All payments are processed by Apple. We never see or store your payment information.
  • To manage your entitlement across devices, the app uses RevenueCat, a subscription-management service. RevenueCat records your purchase history and an anonymous app-user identifier (a random ID or your device's vendor identifier, IDFV). This is used only to determine whether Pro is active. It is used for app functionality, not for tracking, and it is not linked to your name or email.
  • See RevenueCat's privacy policy at revenuecat.com/privacy.

Notifications

If you enable expiration and rotation reminders (a Pro feature), the app schedules local notifications on your device. These are generated on-device and are not sent through our servers.

What we do not do

  • No analytics SDKs, no advertising SDKs, no third-party trackers.
  • No account creation. No email, phone number, or contacts collected.
  • No location access of any kind.
  • No selling, renting, or sharing of your data with third parties.

Data used to track you

None. The app does not track you across apps or websites owned by other companies.

Your choices

  • Access: all your data is visible inside the app.
  • Delete: delete individual plans or reset the app's data from inside the app, or remove everything by deleting the app. This removes data from your device.
  • Manage subscription: manage or cancel your subscription any time in the App Store under your Apple Account settings.

Children's privacy

The app is rated 4+ and does not knowingly collect personal information from anyone. It does not require an account and collects no personal data on our servers.
