Before you decide
Your code, prompts, retrieval indexes, and audit content are not uploaded to Bastille-C3 by ordinary customer-hosted operation. You control the infrastructure and any harness or cloud model providers you choose. Paid license checks contact Polar. Website analytics, checkout, and messages you send us are separate: see the Privacy Policy.
Cancel renewal through the Polar customer portal linked in your billing email, or ask Bastille-C3 support for help. The subscription remains active in a pending-cancel state until its current renewal date, then is not renewed. Cancellation does not automatically create a prorated refund. Cancellation details.
Voluntary refunds are discretionary. Send a support request showing the Bastille-C3 issue, your cooperation with troubleshooting, and reasonable time for us to resolve it. Harness, LLM provider, customer hardware/network, and other outside-control problems do not qualify for voluntary refunds. Read the Refund Policy.
Install your downloaded archive, then use /bastille-license refresh inside Pi or zrag license refresh in your terminal. The license tools use Polar to activate and validate your entitlement. Paid Pi extensions share the key managed by bastille-license. Follow the installation guide.
Apache-2.0 redistribution and commercial-use rights remain intact, subject to that license. The No-Reselling Policy addresses paid subscriptions, credentials, and access. It does not rewrite the applicable software license.
Revolutions move fast. AI is no different - every few months brings a new leap, a new capability nobody had before.
But a revolution only outruns you if your defenses are already hollow. On July 14, 1789, revolutionaries took the Bastille in a single day - not because it was unbreakable, but because it had quietly stopped being a real fortress at all. Thin garrison, symbolic authority, no real governance behind the walls.
We named the product after that fortress on purpose - as a warning, not a celebration. Bastille-C3 exists so your infrastructure, security, and governance aren't the hollow walls that fall the moment things move fast. It's the stronghold that lets you adopt what's new without losing control of what's already built: observability, security, and governance that hold - even mid-revolution.
Don't let your project be the one that gets stormed. Keep the fortress standing.
No. Bastille-C3 is an additional governance layer. Its protection depends on the module, configuration, supported harness, and environment. You remain responsible for approvals, provider choices, backups, and reviewing generated work. We do not provide, curate, or manage harness or model content. Terms of Service.
