Privacy Policy

Effective Date: May 18, 2026

This Privacy Policy is designed to help you (“you,” “your,” or “User”) understand how LockScreen Calendar (“we,” “us,” “our,” or “LockScreen Calendar”), operated by SilverAI, collects, uses, and protects your personal information.

LockScreen Calendar turns your iPhone Lock Screen into a personalized calendar. It lets you create custom wallpapers that overlay your schedule, tasks, and reminders directly on your Lock Screen, syncing with Google Calendar, Apple Calendar, and your reminders. When you use our mobile application and services, you trust us with your personal information. We take your privacy very seriously.

We hope you take the time to read this carefully, as it is important. If there are any terms in this Privacy Policy that you do not agree with, please discontinue use of our Application and services.

This Privacy Policy applies to all information collected through our mobile application (“App”) and/or any related services, sales, marketing, or events (we refer to them collectively in this Privacy Policy as the “Services”).

1. Information We Collect

1.1 Information Collected Automatically

Certain information such as your IP address and/or browser and device characteristics is collected automatically when you access the LockScreen Calendar app.

We automatically collect certain information when you visit, use, or navigate the App. This information does not reveal your specific identity (like your name or contact information) but may include device and usage information, such as your IP address, browser and device characteristics, operating system, language preferences, referring URLs, device name, country, location, information about how and when you use our App, and other technical information. This information is primarily needed to maintain the security and operation of our App, and for our internal analytics and reporting purposes.

If you use our App, we also collect the following information:

  • Mobile Device Data. We automatically collect device information (such as your mobile device ID, model, and manufacturer), operating system, version information, and IP address.
  • App Usage Data. We automatically record usage data, including: wallpapers you have created, calendar layouts and styles selected, frequency of app interactions, customization choices (colors, dim levels, week start preference), and feature usage patterns.
  • Purchase History. We automatically collect your purchase history and subscription information within the App to provide appropriate functionality and access.
  • Push Notifications. We may request to send you push notifications regarding your account, upcoming event reminders, or app updates. If you wish to opt out of receiving these communications, you may turn them off in your device settings.

1.2 Information You Provide to Us

When using LockScreen Calendar, we collect information that you provide directly to us, including:

  • Account Information. If you choose to create an account, we collect personal information such as your name, email address, and password.
  • Wallpaper Preferences. We collect information about your wallpaper and Lock Screen design choices, including selected layouts (calendar, agenda, to-do list), color themes, dim levels, week start day (Monday or Sunday), and “Today” marker styles (dot, ring, or square).
  • Event and Reminder Data. When you create, edit, or remove events and reminders within the App, we process information such as event titles, dates and times, repeat schedules (daily, weekly, monthly, etc.), reminder offsets, and notes you choose to include.
  • Contact Information. When you contact our support team, we collect information you provide during the communication, including conversation history, issue details, and any other information you choose to provide.

1.3 Calendar and Reminder Access

LockScreen Calendar integrates with your device's calendar and reminders so your schedule can be overlaid on your Lock Screen wallpaper. When you grant access:

  • Calendar Access. The App requests permission to read events from Apple Calendar and, if you choose, Google Calendar. This access is used solely to display your upcoming events on your generated wallpapers and within the App.
  • Reminders Access. The App requests permission to read and write to your device's Reminders so that tasks and to-dos can be displayed alongside your calendar.
  • On-Device Processing. Calendar events, reminders, and task data are processed locally on your device to render your wallpapers. We do not collect, store, or transmit the contents of your calendar events or reminders to our servers.
  • Revoking Access. You can revoke calendar or reminders access at any time through your device's system settings. Doing so will disable the related features in the App.

1.4 Photos and Media Access

LockScreen Calendar lets you use your own photos as wallpaper backgrounds. When you use this feature:

  • Photo Library Access. The App requests permission to access photos you select from your device's photo library so you can use them as wallpaper backgrounds.
  • Image Processing. Photos you choose are processed locally on your device to compose your Lock Screen wallpaper. We do not upload your photos to our servers.
  • Photo Storage. The finished wallpaper is saved to your device's photo library at your direction so you can set it as your Lock Screen. We do not retain copies of your photos or generated wallpapers.

2. How We Use Your Information

We process your information for purposes based on legitimate business interests, the fulfillment of our contract with you, compliance with our legal obligations, and/or your consent.

    • Generate Lock Screen wallpapers that display your calendar, agenda, and tasks
    • Sync and display events from Apple Calendar and Google Calendar
    • Send reminders for upcoming events at the lead times you configure
    • Remember your style preferences (colors, dim levels, week start, today markers)
  • To Create, Log In, and Manage Accounts. If you choose to link your account with us to a third-party account (such as your Google or Apple account), we use the information you allow us to collect from those third parties to facilitate account creation, login, and calendar sync.

4. Third-Party Calendar Integrations

LockScreen Calendar can connect to third-party calendar providers at your direction:

  • Google Calendar: If you choose to connect your Google account, we use Google's authorized APIs to read calendar events you have granted us access to. Our use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We do not use Google Calendar data for advertising, and we do not transfer this data to others except as necessary to provide the App's features, comply with applicable law, or with your explicit consent.
  • Apple Calendar and Reminders: Apple Calendar and Reminders integration uses the system-level frameworks provided by iOS. Access is granted by you through iOS system permissions and is read locally on your device.
  • Revoking Access: You can disconnect Google Calendar at any time from within the App or via your Google Account permissions page. You can revoke Apple Calendar and Reminders access from your iOS Settings.

5. Analytics

We may use third-party Service Providers to monitor and analyze the use of our Services.

  • Google Analytics: Google Analytics is an analytics service provided by Google that tracks and reports mobile app usage. Google uses the data collected to track and monitor the use of our Services. This data is shared with other Google services. For more information about Google's privacy practices, please visit: https://policies.google.com/privacy
  • Firebase: We may use Firebase (owned by Google) for app performance analytics, crash reporting, and improving user experience.

6. Data Retention

We keep your information for as long as necessary to fulfill the purposes outlined in this Privacy Policy, unless otherwise required by law.

We will only keep your personal information for as long as it is necessary for the purposes set out in this Privacy Policy, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements). No purpose in this policy will require us to keep your personal information for longer than 1 year after your account becomes inactive.

When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize it, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.

You have the right to:

  • Access personal information we hold about you
  • Correct inaccurate or incomplete information
  • Delete your personal information from our systems

8. Security

We aim to protect your personal information through a system of organizational and technical security measures.

We have implemented appropriate technical and organizational security measures designed to protect the security of any personal information we process, including:

  • Data encryption during transmission (SSL/TLS)
  • Encrypted password storage
  • Strict access controls for user data
  • On-device processing of calendar, reminder, and photo data wherever possible

However, please note that we cannot guarantee that the internet is 100% secure. Although we will do our best to protect your personal information, transmission of personal information to and from our App is at your own risk. You should only access the Services within a secure environment.
