Privacy Policy

App usage statistics

The iOS welcome screen explains the Terms and usage data collection. After you consent by selecting Get started, Google's Firebase Analytics measures screen views, ranking filters, search result counts, saved apps and countries, and sign-in outcomes. Firebase Analytics collection does not start before acceptance. After getting started, you can turn collection off at any time in Settings → Privacy Policy → Share usage statistics. This choice is saved on this device, and the service remains available when analytics is off.

Analytics may include an app instance identifier, app, operating system and device information, and approximate location. We do not send account IDs, names, email addresses, search terms, authentication tokens or saved-app identifiers to Analytics. We disable IDFA and IDFV collection and ad personalization.

Contact the operator by email with analytics questions or requests to withdraw consent or delete data. Uninstalling the app stops new analytics from that installation. Previously transmitted statistics remain subject to the configured Google Analytics retention policy and are not automatically deleted with an AppChart account. Statistics are not linked to your account ID, which limits our ability to identify individual records. Sending an email does not automatically change collection settings on your device.

Operator and contact

AppChart is operated by Studio138. Contact andjava10@gmail.com for privacy questions and requests to access, correct, or delete your information.

Information and purposes

When you use account features, we use the user identifier, email address, and, when provided, name and profile image from Apple or Google for authentication and account management. AppChart does not receive your Apple or Google password.

We store the apps you save, selected countries, list order, and account preferences so you can use your collection across devices and the web. Selecting a country chooses a storefront; it does not collect your device location.

If you sign in and allow push notifications, we link an app installation identifier, the Apple Push Notification service (APNs) device token, and notification permission status to your account to deliver rank change alerts. We also process alert rules, alert history, and delivery results to provide the feature and investigate errors. These identifiers are not used for advertising tracking.

When you contact us, we use your email address and message to respond and investigate the issue. Do not include passwords, verification codes, or login tokens.

Hosting and authentication services may process request times, IP addresses, request paths, errors, and connection information in service and diagnostic logs. The website uses Vercel Web Analytics for page usage statistics. The iOS app does not include that web analytics SDK.

External services

Supabase provides authentication and storage for accounts and saved apps. Vercel hosts the website and APIs. Apple and Google provide your chosen sign-in service and store information. Loading icons or screenshots, or opening a store link, can send standard network request information to the corresponding provider.

Processing locations and retention depend on each service's configuration and policies. The relevant provider's privacy policy also applies when you use Apple or Google sign-in and store pages.

Push notifications are delivered through Apple's APNs. We send the device token and notification content to Apple for delivery. You can change notification permission in iOS Settings, turn off push notifications in AppChart Settings, and change per-app alert rules. Signing out revokes the device's delivery link to that account. Deleting an account also removes associated alert settings, history, and other user data.

Storage on your device

The iOS app stores its login session in Keychain and caches public app information and member collections to display content quickly. Theme and language preferences, the accepted document version, acceptance time, display language, and analytics consent status are stored locally. Signing out or deleting an account clears the app's local session and member-specific caches.

The website uses browser storage and cookies for sign-in and preferences such as language and theme. You can clear local data through your browser's site-data settings. Deleting the server account requires a separate account deletion request.

Retention and account deletion

Account and saved-app information is retained while we provide your account features. To start deletion in the iOS app, open Settings → Signed-in account → Delete AppChart account. Once deletion completes, we remove the authentication account, profile, saved apps and countries, and associated user data from the operational database. If you use the same AppChart account on the web, that collection will no longer be available there either.

This does not delete your Apple or Google account. If automatic Apple authorization revocation is unavailable, the app provides instructions for removing the connection yourself. Uninstalling the app or signing out alone does not delete your server account.

Infrastructure logs and backups expire under retention schedules separate from the account database. Information required by law is retained only within the scope and duration of that obligation. Contact the operator for specific retention or deletion questions.

Your choices and policy changes

Public rankings are available without signing in. Sign-in is needed for account features such as syncing saved apps. You may request access, correction, or deletion of your personal information. We may request proportionate identity verification to protect other people's information.

We update this page and its effective date when this policy changes. Material changes will also be communicated in the service when appropriate.
