7. Data Retention Policies
We retain personal information for as long as necessary to fulfill the purposes for which it was collected, including to satisfy any legal, accounting, or reporting requirements. The criteria used to determine appropriate retention periods include:

Contact form submissions and general inquiry data are typically retained for two years from the date of the last communication. Website analytics data with no personally identifying information may be retained indefinitely for trend analysis.
