We’re glad you asked.

What payment methods do you accept?

We accept all major credit cards, debit cards, and (for Max accounts) invoicing via bank transfer.

Annual plans can also be paid via invoice upon request.

Are there any hidden fees?

No.

Everything you see in the plan is exactly what you get.

The only extras are optional one-time audit services or add-ons you explicitly choose.

Can I change my subscription plan later?

Anytime. Upgrades happen instantly; downgrades take effect at the next billing cycle.

Your data and settings stay intact no matter the tier.

How do I contact customer support?

Inside the app you’ll find fast chat support available 7 days a week.

Max customers get priority support with guaranteed faster response times.

What should I do if I have feedback or a complaint?

We genuinely care about feedback — good and bad.

If something feels off, slow, or confusing, tell us.

We respond to every message, and many new features come directly from user suggestions.

How do you ensure quality assurance for your services?

Every AI-generated result goes through multiple validation layers:

– static analysis

– pattern comparison

– confidence scoring

– safety guardrails

And for Max accounts, you can configure custom QA logic that matches your code style and rules.
