What happens after the trial?

After your 14-day Pro trial, your Pro subscription continues unless canceled before trial end. You can cancel anytime from billing settings.

Is there a free trial?

Yes. Starter and Pro both start with a full 14-day free trial on every checkout — no charge until day 15, cancel anytime from billing settings. The Free plan also lets you run every decision engine on your own numbers with no credit card, capped to 1 run per engine per day.

What payment methods do you accept?

Payments are processed by Stripe, which holds PCI DSS Level 1 certification as the payment processor. We accept all major credit and debit cards. Enterprise plans are handled directly — contact us for details.

Yes. Upgrade or downgrade at any time. Changes take effect immediately, and we prorate billing automatically.

Absolutely. All data is encrypted at rest and in transit. Your data stays isolated and never trains public AI models. See our Security page for details.

Do you train public models on my data?

No. Your workspace data is isolated for your operational workflows and is not used to train public models.

Pricing

Pricing that proves first.

Built for teams that need proof before they commit. Every decision engine is runnable on every plan. Starter and Pro add exports, AI refinement, and faster iteration workflows — each with a 14-day free trial. Every paid capability shown below matches the live product contract.
