Introduction

LastCig is a quit-smoking tracker that helps you monitor cigarette consumption, resist cravings, and track your progress toward a smoke-free life. We are committed to protecting your privacy and being transparent about our data practices. This policy explains what data the app stores, how it is used, and what limited information is shared with third-party services.

Your Data Stays on Your Device

LastCig is built with an offline-first, local-only architecture. Your smoking logs, craving logs, and profile information are stored entirely on your device and are never uploaded to any server.

Limited service data may be sent to Google, Firebase, and RevenueCat for subscription verification, purchase processing, analytics, crash reporting, notifications, and app reliability. Your smoking logs, craving logs, triggers, intensity levels, quit date, and health calculations are not intentionally uploaded as analytics or crash-report content.

We do not sell your personal data.

What Data Is Stored on Your Device

The app stores the following data locally on your device to provide its core features:

  • Smoking logs: Number of cigarettes smoked, cost, triggers (e.g. stress, coffee, social), intensity level, and the date and time of each entry
  • Craving logs: Intensity level, triggers, and the date and time each craving was resisted
  • Profile information: Quit date, cost per cigarette, and currency preference

This core quit-smoking data exists in the app’s local database on your device. It is not synced to a LastCig server or intentionally shared with third parties as analytics event content.

No Account or Sign-In Required

LastCig does not require you to create an account, sign in, or provide any personal information such as your name, email address, or phone number. You have full access to the app without any form of registration.

Since there is no account system, there are no credentials stored, no passwords to manage, and no need for sign-out or account deletion functionality.

Subscription and Payment Processing

LastCig requires an active subscription to use. Your subscription transaction is processed through Google Play billing. The app uses RevenueCat as a subscription management service to verify your subscription status.

During this process, RevenueCat and Google Play may receive:

  • A pseudonymous device identifier (not linked to your personal identity)
  • Subscription status (active, expired, or trial)
  • Purchase transaction details (product purchased, price, date)

RevenueCat does not receive any of your smoking logs, craving data, or health information. For more information, see RevenueCat’s privacy policy at revenuecat.com/privacy and Google Play’s terms at play.google.com/about/play-terms.

Firebase Analytics

LastCig uses Firebase Analytics to understand app usage and improve the subscription funnel, onboarding experience, paywall flow, and general app reliability. Analytics events may include app interactions such as screens viewed, onboarding progress, paywall views, subscription actions, and general feature usage.

Firebase Analytics may collect app or device identifiers, app interactions, approximate location such as country or region, device and app information, timestamps, and purchase or subscription revenue data shared from Google Play.

We do not intentionally send your smoking logs, craving logs, triggers, intensity levels, quit date, or calculated health recovery data to Firebase Analytics as event content.

Firebase Crashlytics

LastCig uses Firebase Crashlytics to detect crashes, diagnose stability problems, and improve app reliability. Crashlytics may collect crash logs, diagnostic information, device and app information, operating system version, timestamps, diagnostic identifiers, and crash context.

Crashlytics is used for app reliability and debugging. It is not used to track your smoking behavior, cravings, quit progress, or health recovery.

Internet Permissions

The app requires internet access for subscription verification, purchase processing, Firebase Analytics event delivery, Firebase Crashlytics diagnostics, notifications, Google Play services, and app updates via the Google Play Store.

Notifications

LastCig uses notifications to send you a reminder before your free trial ends. This feature is powered by Firebase Cloud Messaging, which generates a pseudonymous device token (Firebase Installation ID) to deliver notifications to your device.

This token is not linked to your identity. No smoking data, craving data, or personal health information is sent through the notification system.

Data Retention and Deletion

Your core quit-smoking data is stored locally on your device, and we do not keep a cloud copy of it. Firebase, Google Play, and RevenueCat may retain limited service data according to their own policies for analytics, crash reporting, notifications, subscription processing, and purchase verification.

You can delete all app data at any time by:

  • Using the “Delete My Data” option in the app’s Profile screen
  • Clearing the app’s data in your device settings
  • Uninstalling the app from your device

Once deleted, the data cannot be recovered as there is no backup or cloud copy. You must cancel your subscription separately through Google Play Store settings. Uninstalling the app does not cancel your subscription.

LastCig Shorts Publisher (YouTube)

LastCig Shorts Publisher is an internal tool that LastCig uses to upload its own short videos to its own YouTube channel, @lastcigapp. It is not offered to the public, and the only Google account that signs in to it is LastCig’s own.

When LastCig signs in, the tool asks Google for two permissions through the YouTube Data API:

  • Upload videos to the LastCig YouTube channel
  • View the LastCig channel and its videos, to confirm which channel a video goes to

The tool stores the sign-in token on LastCig’s own computer. It does not collect, store or share data about any other YouTube user or viewer. It stores only the ID and link of each video it uploads.

The tool’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. It uses YouTube API Services and is bound by the YouTube Terms of Service and the Google Privacy Policy.

Access can be removed at any time at myaccount.google.com/permissions.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in the app with an updated “Last updated” date.
