Homeschool Tracker is a wonderful software for keeping your homeschooling records.  The creators were homeschoolers themselves.  They have a Basic version that is free, with no strings attached.  They plan to offer it for as long as the Lord allows them to.  The Basic version is a good program in its own right.  I used it for a year before they came out with the Plus version and it met my needs.

One of the best perks of the software are the upgrades.  Each major upgrade adds some tremendous features which a user may use, or not use, depending on their needs.  The creators consider each request for new or changed features, and try to incorporate them into the next big updates (which is ALWAYS free).  They recently added the ability to share lessons plans among users.  So, if I have set up a lesson plan for using my math textbook, and I have a friend with HST+  that is using the same textbook, I can send them the lesson plan to import into their program.  This feature is only for non-copyrighted plans.  For example, Sonlight publishes an IG to go with books you can readily check-out from the library.  Sonlight holds the copyright for the way the books are taught from, so I couldn't share that lesson plan.  I can however, enter those lesson plans into my HST+ for my personal use.  (That is all hypothetical ~ I don't use Sonlight).
