The free plan for Everlance includes 30 auto-detected trips per month. If you upgrade to Premium, you will then have unlimited auto-detection for all your trips. This means that no matter how many you take, your trips will be automatically recorded! However, upgrading to Premium doesn't "unlock" any trips you took previously while on the free plan. All of the trips that we have recorded can be seen by logging into your Everlance account and viewing the Trips->All tab.
If you have any other questions, please email us at firstname.lastname@example.org. We're happy to help!
