Lifeline Weeks stores all data locally on your device. No accounts. No servers. No tracking.

Privacy Policy

Effective date: March 24, 2026  ·  Lifeline Weeks iOS App

01 Overview

Lifeline Weeks ("the App", "we", "our") is an iOS application developed by Cuong Sam Manh. We are deeply committed to your privacy. This policy explains clearly and completely what data the App uses, where it stays, and what rights you have.

Short version: All data you enter — including your birthday and life expectancy — is stored exclusively on your device. We do not collect, transmit, sell, or share any personal information. There are no servers, no accounts, and no analytics.

02 Information We Do Not Collect

Lifeline Weeks does not collect, store remotely, or transmit any of the following:

  • Your name, email address, or any contact information
  • Your date of birth or life expectancy setting
  • Location data of any kind
  • Device identifiers, advertising IDs, or IP addresses
  • Usage analytics, crash logs sent to third parties, or behavioral data
  • Any data from your contacts, camera, microphone, or photo library

03 Data Stored Locally on Your Device

The following information is stored only on your device using iOS system storage (UserDefaults and App Group container shared with the widget):

  • Your birthday — used to calculate weeks lived and power the week grid
  • Life expectancy setting — used to determine the total grid span
  • Notification preferences — day, time, and tone you select
  • Theme preference — your chosen visual appearance
  • Onboarding completion state — to avoid showing the intro repeatedly

This data never leaves your device unless you use iOS system backup (iCloud Backup), which is governed by Apple's own Privacy Policy.

04 Notifications

If you enable notifications, the App will request iOS permission to send local push notifications. These notifications are generated entirely on-device using pre-written message pools — no network request is made to send or schedule them. You can revoke notification permission at any time in iOS Settings → Notifications → Lifeline Weeks.

05 Widgets

The Lifeline Weeks home screen widget reads data from the shared App Group container stored locally on your device. It does not connect to the internet or any external service. Widget data refreshes at midnight each day or when the main app triggers a reload.

06 In-App Purchases

Premium theme purchases are processed entirely through Apple's App Store and StoreKit framework. We do not have access to your payment information, Apple ID, or purchase history. All billing is handled by Apple subject to Apple's Privacy Policy and Terms of Service.

07 Third-Party Services

Lifeline Weeks does not integrate any third-party SDKs, analytics platforms, advertising networks, or crash-reporting tools. There are no third parties that receive data from this App.

08 Children's Privacy

The App is suitable for users of all ages. Because we do not collect any personal data whatsoever, there are no special risks for children. We do not knowingly collect information from any user, of any age.

09 Changes to This Policy

If we ever materially change this Privacy Policy, we will update the effective date above. Any changes will be posted at this URL. Continued use of the App after changes constitutes acceptance of the updated policy.

All rights are reserved.
