| Important considerations |
You operate the server and backups. Daily visitor IDs do not identify the same person across days. Support is community-based, with no SLA. Optional AI clients receive the query results they request; self-hosting does not keep those results out of the client. | Clarity is vendor-hosted and uses cookies. Teams must review consent and data policies; it emphasizes qualitative behavior analysis rather than replacing a complete first-party analytics stack. |
