FAQ
Good questions
Is it allowed in exams?
Yes — AinoCalc devices are non-programmable scientific calculators. Notes are read-only study material and can be locked with exam mode before entering the room.
How long does shipping take?
Free worldwide shipping: 3–6 business days to US/EU/CA/UK, 6–12 days elsewhere. Every order is trackable and insured.
What payment methods do you accept?
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, Alipay and WeChat Pay — all through encrypted, PCI-DSS compliant checkout.
What if I don't like it?
30-day no-questions-asked returns with a full refund, plus a 2-year warranty (3 years with the bundle) covering any defect.
Does the AI need internet?
No. The AI engine runs entirely on-device. No account, no cloud, no data collection — your notes never leave the calculator.
Stop re-deriving. Start remembering.
