Common questions
Why one-time, not subscription?
Subscriptions for tools that do one specific thing are greedy. Pay once, own it forever. We update prompts every 2 weeks free for life.
Can I get a refund?
Yes — within 14 days of purchase, no questions asked. Email hello@toolvein.com. EU consumer law applies.
How do payments work?
Payment is processed via Stripe through ExtensionPay. We never see your card. After payment, your tier activates automatically across all installations within ~1 minute.
