| Who it's not for | Non-technical teams wanting zero-admin cloud storage | Non-technical users wanting zero-maintenance cloud storage |
| Privacy | No known public vulnerabilities found in the sources reviewed.¹ | Active 2026 advisories including a server auth bypass; self-hosted installs require manual hardening. |
| Support quality | No support-quality evidence in sources | Active community forums; vendor support costs extra |
