Soapstone collects location information and device ids for devices running the app. Location information is used to determine which messages are within range of your device to be read. Device IDs are used to track which device wrote which messages so they can be deleted later if desired. Your location is only ever stored when a message is written by your device to place it correctly in the world to be read by others. Others are able to read messages, but we never publicly identify which device wrote it.
