Privacy Policy

Last updated: May 16th 2023


Missing Sync ("we," "us," or "our") respects your privacy and is committed to protecting it through compliance with this privacy policy. This privacy policy describes the types of information we may collect from you or that you may provide when you use our web application, Missing Sync (the "Service"), and our practices for collecting, using, maintaining, protecting, and disclosing that information.

Please read this policy carefully to understand our policies and practices regarding your information and how we will treat it. By accessing or using the Service, you agree to this privacy policy. This policy may change from time to time, and your continued use of the Service after we make changes is deemed to be acceptance of those changes, so please check the policy periodically for updates.

Information We Collect

When you use the Service, we collect the following types of information from you:

  • Google Calendar data: We access your Google Calendar data through Google APIs to synchronize events with Notion. We store your Google OAuth token to authenticate and access your Google Calendar data.
  • Notion data: We access your Notion data to synchronize events with your Google Calendar. We store your Notion API token to authenticate and access your Notion data.
  • CalDav data: We use CalDav to connect to other calendar services, if applicable. We store your CalDav credentials to authenticate and access these services.

How We Use Your Information

We use your information to:

  • Provide the Service: We use your Google Calendar, Notion, and CalDav data to synchronize events between your calendars and Notion.

Data Retention

We retain your information as follows:

Data Security

We take the security of your data seriously. We use SSL for encrypted communication and re-encrypt all stored credentials, including your Google OAuth token, Notion API token, and CalDav credentials. While we strive to use commercially acceptable means to protect your data, we cannot guarantee its absolute security.
