Privacy Policy

Effective Date: August 28, 2024

Thank you for using LangKey (hereinafter referred to as "the App"). We are committed to protecting your privacy and personal information. This Privacy Policy explains how we collect, use, and safeguard your information. Please read this policy carefully before using the App.

Using LangKey allows you to safeguard your real mailbox from the risk of exposing personal information. Your temporary email address is completely anonymous. Your details, including personal information, communication partners, IP address, and email address, are kept confidential and secure.

Your privacy is our top priority. You do not need to worry about your data; we ensure complete protection. Access to your data is limited to you and is available only for the duration of the temporary email address.

Information Collection

In the Free Version, we do not collect any personal data. As with most standard apps and websites, we use log files which include IP addresses, browser types, Internet Service Providers (ISPs), referring/exit pages, platform types, date/time stamps, and click counts to analyze trends, administer the site, track user movements in aggregate, and gather broad demographic information. IP addresses and other data are not linked to personally identifiable information.

In the Premium Version, no additional personal data is collected except what is necessary for processing payments through Google Play or Apple iTunes. No registration is required to use the service.

Information Use

We use your information solely for the following purposes:

  • To provide and maintain the core functionalities of the App.
  • To ensure you can smoothly generate temporary email addresses and manage emails.
  • To improve the performance and user experience of the App.

Third-Party Services

Our App integrates with third-party services that may collect and use your information. These services include:

  • Google AdMob: We use Google AdMob for displaying advertisements. Google AdMob may collect information about your device and app usage to deliver relevant ads. For more details, please refer to the Google AdMob Privacy Policy.

Subscription

The App supports in-app subscriptions. A subscription removes advertisements and provides access to member-exclusive email addresses. During the subscription process, you will be asked to provide payment information to complete the purchase. Payment processors handle this information and are subject to their own privacy policies.

Information Protection

We employ appropriate technical and managerial measures to protect your information. However, please be aware that no data transmission over the Internet can be guaranteed to be completely secure.
