            <p>
              SnapOtter is a self-hosted, open-source file processing application. Your instance is
              operated and controlled entirely by whoever deployed it. This policy describes how the
              software itself handles your data.
            </p>
          </section>

          <section>
            <h2 className="text-lg font-semibold text-foreground mb-2">Local Processing</h2>
            <p>
              All file processing happens entirely on the server where SnapOtter is deployed. Your
              files are never sent to external services or third-party APIs. When you upload a file
              for processing, it is handled in memory or in temporary storage on the host machine
              and is not retained after the operation completes.
            </p>

            <h2 className="text-lg font-semibold text-foreground mb-2">Product Analytics</h2>
            <p>
              SnapOtter includes optional, anonymous product analytics. When you choose to
              participate, the following is collected:
            </p>
            <ul className="list-disc ps-5 mt-2 space-y-1">
              <li>Which tools you use (e.g., "crop tool used")</li>
              <li>Error reports without file data</li>
              <li>App version and performance metrics</li>
            </ul>
            <p className="mt-2 font-medium">What is never collected:</p>
            <ul className="list-disc ps-5 mt-2 space-y-1">
              <li>Your images, PDFs, and files</li>
              <li>File names and contents</li>
              <li>Any personal information or IP addresses</li>
            </ul>

          <section>
            <h2 className="text-lg font-semibold text-foreground mb-2">Your Choice</h2>
            <p>
              Each user is asked individually on first login whether to participate. You can change
              your choice anytime in Settings. Server administrators can disable analytics entirely
              by setting{" "}
              <code className="text-xs bg-muted px-1 py-0.5 rounded">ANALYTICS_ENABLED=false</code>.
            </p>
          </section>

          <section>
            <h2 className="text-lg font-semibold text-foreground mb-2">Data Storage</h2>
            <p>
              If authentication is enabled, the application stores user accounts (usernames and
              hashed passwords) in a PostgreSQL database on the host machine. If you use the Files
              feature, uploaded files are stored on the server's filesystem. All stored data remains
              entirely under the control of the instance operator.
            </p>
          </section>

          <section>
            <h2 className="text-lg font-semibold text-foreground mb-2">Third-Party Services</h2>
            <p>
              All processing happens locally; your files are never sent anywhere. If you opt in to
              product analytics, anonymous usage data is sent to PostHog and Sentry as described
              above. AI-powered features run locally using bundled models. No other external
              services are contacted.
            </p>
          </section>

          <section>
            <h2 className="text-lg font-semibold text-foreground mb-2">Open Source</h2>
            <p>
              SnapOtter is fully open source. You can audit the source code to verify these claims
              at any time. Transparency is a core principle of this project.
            </p>
          </section>

          <section>
            <h2 className="text-lg font-semibold text-foreground mb-2">Your Control</h2>
            <p>
              Because SnapOtter is self-hosted, the instance operator has full control over all
              data. You can delete your data at any time by removing files from the server or
              deleting the database. No data exists outside of your infrastructure.
