Subprocessor List
These are the categories of third-party service providers ("subprocessors") that may process personal information on OnlyHOA's behalf to operate the Platform. Each is engaged under confidentiality and data-protection obligations and processes information only to provide its service to us. We keep this list current as our infrastructure evolves.

This register accompanies our
Privacy Policy and
Data Processing Addendum. It lets us describe provider
categories in the policy itself while giving customers and residents transparency into the specific providers, without pinning a brittle list into the policy text.

Runs locally — listed for transparency, but receives no data: MaxMind GeoLite2 is used to approximate a sign-in's city from an IP address. The lookup runs against a database stored on our own servers, so no information about you is sent to MaxMind (its license key is used only to download database updates).
Providers may change as we improve the Platform. Management-company customers can request advance notice of material subprocessor changes under our Data Processing Addendum. Questions: legal@onlyhoa.com.
