This ensures your data stays private, and usage is billed directly by the AI provider based on their pricing.

Accepted Answer

Question 22

Question 23

What payment methods are accepted?

Accepted Answer

We accept major credit/debit cards and use Stripe as our payment processor.

Question 24

What happens if I downgrade from a premium plan to the free plan?

Accepted Answer

If you downgrade to the free plan, you'll be limited to 10 GPT calls per day. To avoid losing access to previous AI-generated content or exceeding the limit, we recommend converting all GPT formulas to static text. Simply open the relevant Sheet and go to Optimising GPT Mate > Convert GPT Formulas to Static Text > All Cells. This locks in the AI responses and prevents additional calls from being made.
