Un4gettable 2 steps installation process explained:

  1. Add Un4gettable to Google Calendar.

  2. Click the sign in with Google button.


Add Un4gettable to Google Calendar:  Install un4gettable as a Google Calendar sidebar Gadget.
Click the sign in with Google button: you'll be asked to give Un4gettable permissions to access your Google Calendar, Google Contacts  and basic profile info. Un4gettable needs those permissions in order to do its job. We need to access your calendar in order to know, for example, if you changed the event time, so that the reminder we send will be relevant. Un4gettable needs access to Google Contacts in order to know the SMS Reminder recipient phone number.
We won't give your data to a third party without your permission. 

If you are seeing this from your mobile device you should know that you can use Un4gettable via your mobile device but first time installation and setup is made using a desktop browser. Tip: send yourself an email reminder so that you'll remember to install Un4gettable the next time you are using a desktop. www.un.4gettable.com
