DailyList Privacy Policy

Last updated: November 14, 2026

DailyList is developed by Cygnus X Enterprises LLC. This Privacy Policy applies to DailyList for Android, iOS, macOS, and Windows, including versions that offer optional account and synchronization features.

Information stored locally

DailyList stores your lists, tasks and their completion status, preferences, colors, and saved lists locally on your device. You can use the local list features without an account. In versions that offer Synchronize lists, list content is sent to our server only when you sign in and enable synchronization.

On Android, Android backup and device-transfer features may copy locally stored information to your Android backup provider or another device. Those backups are controlled by Android and your device or Google Account settings.

On Windows, locally saved lists and settings are separate from your Daily List server account. Uninstalling the Windows app does not delete that account or its synchronized data. Local copies and backups may remain depending on the installation method and your Windows backup settings. Use the account-deletion controls described below, or contact us, to request deletion of your server account.

Optional accounts and list synchronization

If you create a Daily List account, we process your email address, a one-way password hash, email-verification status, and account timestamps. We use your email address for sign-in, verification, and password recovery. Account emails are sent through our configured email-delivery service. We also store a generated device identifier, device platform, session records, and synchronization revisions to connect your devices and process updates reliably. Session tokens are kept in the app's secure operating-system storage; we store hashes of session and email-action tokens on the server.

When synchronization is enabled, we store your numbered lists, saved lists, task text, completion status, ordering, and recurring-task schedules on the Cygnus X service at cygnusx.com. This lets devices signed in to the same Daily List account exchange and merge changes. The synchronization database is hosted on our server infrastructure and is separate from Firebase. Turning synchronization off stops further syncing on that device and retains its local lists; it does not by itself delete the account or the server copy. Signing out also retains local lists.

Daily List uses HTTPS with certificate validation for account and list requests. Service and website infrastructure may process technical request information for operation and security.

Advertising and third-party services

The mobile versions of DailyList display advertising using Google AdMob and the Google Mobile Ads SDK. DailyList also uses Google's User Messaging Platform to gather and manage advertising consent where required. The Android and iOS versions may use different advertising and consent configurations.

Depending on the platform, your region, your consent choices, and the advertising configuration, Google and its advertising partners may process:

• Approximate or coarse location derived from information such as your IP address
• Device identifiers, including advertising identifiers when permission allows
• Advertising data, including advertisements viewed or interacted with
• Product-interaction and app-usage information
• Crash, performance, and other diagnostic information

These types of information may be used for third-party advertising, advertising measurement, analytics, fraud prevention, app functionality, and performance improvement. Depending on your location and consent selections, advertisements may be personalized, non-personalized, or limited.

For more information, see Google's Privacy Policy and advertising information.

Analytics and diagnostics

Mobile versions may use Firebase Analytics and Firebase Crashlytics to understand app use and diagnose crashes. These services can process app interaction, device/app identifiers, and diagnostic information according to their configuration and Google's policies. List synchronization does not use Firestore or Firebase Storage. The current macOS app does not embed the Google advertising or Firebase SDKs described here.

Advertising on iOS

DailyList does not request permission to track you across other companies' apps or websites, and does not intentionally access Apple's Identifier for Advertisers (IDFA). DailyList requests non-personalized or limited advertising on iOS.

Ads may still use contextual information, such as general app context and approximate location derived from your IP address. Google may still process limited device information, advertising interactions, diagnostic and performance information, and fraud-prevention information. Non-personalized advertising does not mean that no information is processed.

Consent and privacy choices

Where required, you can review or change your Google advertising-consent choices from DailyList's Options screen using Privacy options. The availability of this option depends on your region and Google's consent requirements.

On Android, DailyList uses Google's User Messaging Platform to request and record privacy choices where required. The Google Mobile Ads SDK may process your IP address, app interactions, diagnostic and performance information, and advertising, app-set, or related device identifiers. DailyList uses internet and network-state access to load advertisements and privacy messages. It does not request access to your microphone, camera, contacts, phone calls, photos, files, or precise location.

Purchases

DailyList may offer a one-time purchase that removes advertisements. Purchases are processed by the applicable app store. Cygnus X does not receive your full payment-card or banking information. The store may provide purchase status and related transaction identifiers so the app can confirm and restore a purchase.

Data retention and deletion

Local lists remain on your device until you remove them. You can delete tasks and saved lists through the app. Android users can clear the app's storage in Android Settings. Removing a mobile app does not necessarily remove copies held in device backups. On Mac, deleting the application can leave its local Application Support files, backups, and Keychain entries; removing the application alone is not an account-deletion request.

In versions with account deletion, open Server Account or Account & Sync, choose Delete Account, and confirm with your current Daily List password. This permanently removes your account and associated synchronized library from the active service and ends access using its sessions. Existing list copies and local backups on your devices remain there; account deletion is not a remote device-wipe feature. If your version does not offer this control or you need help with deletion, contact us using the address below.

Account and synchronization data is retained by the active service until you delete the account. Operational backups and security records may retain information separately from the active account database; contact us with questions about those copies or a deletion request. Information handled independently by Google or your device-backup provider is governed by that provider's policies and controls.

Children's privacy

DailyList is a general-purpose productivity application and is not specifically directed to children under 13.

Security

DailyList stores list information in the application's private local storage. Account and synchronization requests use HTTPS. Passwords are stored on our service as one-way hashes. Information transmitted by Google's advertising and consent services is encrypted in transit according to Google's documentation. No method of electronic storage or transmission is completely secure.

International processing

Our account and synchronization service uses infrastructure in the United States. Google and its advertising partners may also process information in countries other than the country where you live. Google's processing is subject to Google's privacy policies and applicable law.

Changes to this policy

We may update this Privacy Policy when DailyList's features, advertising systems, purchases, or data practices change. The “Last updated” date at the top of this page identifies the latest revision.
