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. Stripe checkout starts the trial without a card. Add billing before day 15 to keep access; if you do not, trial access ends instead of billing automatically. The Free plan still includes: One free run per tool per day, no account needed.

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.

Yes. 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.
