Frequently asked questions
How do I pay?
Tap the WhatsApp button on the plan you want and the admin will reply with payment details (bank transfer, e-wallet, or QRIS). Your tier is activated within 24 hours of confirmation.
If I self-host, do I still need to pay?
No. Self-hosting is always free. As the server admin you can give any account a plan (including Lifetime) with `bun run admin:upgrade`.
Can I get a refund?
Yes, within 7 days of activation as long as the account hasn't been used heavily. Just message the admin on the same WhatsApp thread.
What's the difference between Monthly Premium and Lifetime?
Monthly is great if you want to try it out or learn at a specific pace. Lifetime is a one-time payment for permanent access, better value for long-term commitment.
What happens if I don't renew?
Your account automatically returns to the Free plan when the active period ends. Your data and progress are preserved, nothing is lost.
