Frequently asked questions
What happens if the SLA is missed?
Penalties are capped in service credits applied to the following month's invoice. Credits are auto-calculated against the contracted uptime tier.
What is excluded from Shield?
Net-new product development is out of scope and belongs to a Care plan. Shield covers monitoring, patching, incident response and backups.
How does on-call work?
Shield Pro and Enterprise include defined escalation windows (8h and 2h respectively) with a documented runbook and post-mortem reports.
Where does my data live?
Inside SessDev-controlled boundaries with least-privilege access; backup snapshots are encrypted off-site per Local Sovereign policy.
Can I exit or downgrade?
Monthly retainers can be downgraded or paused with 30-day notice. Artifacts and schemas are produced in standards-friendly formats so handoff is practical.
