Privacy Policy Requirements for SaaS Companies
SaaS platforms occupy a unique legal position: you are a data controller for your own users' account data, and simultaneously a data processor for any customer data that your users store within your platform. This dual role creates two separate sets of obligations. Your privacy policy must address both — and most SaaS companies get this wrong by only addressing one.
The Controller vs. Processor Distinction
When your user creates an account on your platform, you control their personal data (name, email, billing info). You decide why and how you process it. This makes you a data controller under GDPR. But when that same user uploads their own customer records into your platform, you are processing data on their behalf. This makes you a data processor — and you need a Data Processing Agreement (DPA) in addition to your privacy policy.
Sub-processors: A Critical Disclosure Gap
Most SaaS companies run on a stack of third-party services: AWS or Google Cloud for hosting, Stripe for billing, Intercom or Zendesk for support, Mixpanel for analytics. Under GDPR Article 28, you must maintain a list of all sub-processors and notify your customers when you add or change one. Your privacy policy must identify the categories of sub-processors you use (even if not every individual vendor).
Usage Logs and Behavioral Data
SaaS platforms generate enormous amounts of behavioral data: which features users click, how often they log in, what queries they run, and where they encounter errors. This telemetry data is incredibly valuable for product development but is also personal data under GDPR if it can be linked to an identifiable individual. Your policy must disclose that you collect this data, your legal basis for doing so, and how long you retain it.
Security and SOC2 Compliance
Enterprise customers increasingly require SOC 2 Type II compliance before signing a contract. Your privacy policy is part of the evidence that auditors review. It must accurately reflect your actual data handling practices — any discrepancy between your policy and your actual behavior is a finding in an audit.
