Strasdesign provides a life time free-of charge technical support for backup, trouble with the system and installed application (Joomla 3, facebook module, testimonials, text editor, map, instagram module, contact form module), trouble with hosting from the date of the purchase.
Indeed, I make and host a backup for all my clients in order to make a restoration in case of crash.
For all the other issues (customization, changes in the texts and pictures), Strasdesign provides 8 months free-of charge customization support from the date of the purchase. After this period of 8 months, each intervention on your website will be charged $10 except for the technical interventions described above.
Joomla allows user to install third party applications. Installation of third party application are not included in the customization and technical support.
Note that for all applications some are free and other are not. I will always present you both solutions and let you decide which version you want me to install.
