Frequently asked
- Can I switch plans later?
- Yes. Upgrade or downgrade at any time from Settings → Billing. Prorated credits apply automatically.
- What does the AI token budget mean?
- Protocol recommendations and newsletter drafts use Claude models. Each plan includes a monthly token budget to keep costs predictable.
- Is lifetime really lifetime?
- Yes — one payment, access forever. AI tokens reset monthly; everything else (cycles, inventory, calculators, purity tests) is unmetered.
- Do you offer refunds?
- 30-day money-back on all plans. Contact support from any page footer.
