Frequently asked questions

Monthly vs. Lifetime — which should I pick?

Monthly is the lowest-commitment way in: $9.99/mo, cancel any time. Lifetime is the best long-run value: pay $99.99 once and you keep Pro forever, even if prices rise later. Lifetime pays back in roughly 10 months of monthly.

Can I cancel anytime?

Yes. Cancel monthly from your account billing portal — you keep Pro until the end of the period. Lifetime doesn’t auto-renew so there’s nothing to cancel; it’s permanent.

Is my data private?

All data is encrypted in transit and at rest. We never sell your stack data or health information to third parties.

What payment methods are accepted?

All major credit / debit cards via Stripe. Apple Pay and Google Pay supported on compatible devices.
