Frequently Asked Questions

Why limit to 15 free clicks?

+

We want you to experience the real value before paying. 15 clicks per button are more than enough to prove FenneX’s effectiveness on your own activity.

Is my data sent to your servers?

+

No. FenneX runs 100% client‑side. Your API key, tweets and replies never leave your browser. We see nothing, we store nothing.

Which AI models can I use?

+

FenneX works with Groq (Llama 3.3 70B recommended), OpenAI (GPT-4) and Claude. You bring your own API key – we don’t add any markup.

Can I switch plans?

+

Yes, upgrade is instant. Downgrades apply at the end of your billing period. The lifetime license is one‑time, forever.

Do you offer refunds?

+

We do not offer refunds, but you can try the free plan forever to make sure FenneX works for you before upgrading.

Does this comply with X’s terms of service?

+

Yes. You retain human control over the final click. FenneX is an augmentation tool, not mass automation. You are 100% compliant.
