Applications on unpaid plans are suspended when there aren't any operations performed for two months. As hosting the data comes with a cost, Algolia automatically suspends and then deletes every application after two months of inactivity.
To prevent your application from being removed, make sure to log into your Algolia Dashboard and perform a few searches so that we know it's still in use. In the future, you can run a few searches once every two months and this will keep your application active.
Please note, if you have multiple applications, you'll want to make sure you select the correct application to perform the searches. You can do so by going to the "Applications" tab, selecting the application desired and then performing the searches from the Index tab, as seen below:
