Refund and Cancellation Policy
This policy covers paid memberships on Calculix. It is written to be easy to act on, because a refund policy that is hard to use is not really a policy.
The calculators are free and always will be. A membership only removes advertising and extends saved history. Nothing you pay for changes a calculation.
1. Cancelling a membership
You can cancel at any time from My Account → Subscription, or by emailing info@calculix.in from your registered address.
Cancelling stops any future renewal. You keep ad-free access until the end of the period you have already paid for — cancelling does not cut your access short.
2. When we refund in full
We will refund the full amount, no questions asked, in these situations:
- Within 7 days of purchase, if you are not satisfied with the membership.
- Duplicate payment — you were charged twice for the same period.
- Payment taken but membership not activated — the money left your account and the ad-free access did not start.
- Wrong amount charged — you were charged more than the advertised price.
- Extended outage — the site was unavailable for a significant part of your paid period.
3. When we do not refund
Stated plainly so there are no surprises:
- After 7 days, for a period already substantially used — though see the next section.
- Where the account was suspended for a serious breach of our Terms and Conditions.
- Because a calculation did not produce the outcome you hoped for. The calculators are free, their limits are disclosed on every result, and a membership does not change any number.
4. Part-used periods
If you cancel a quarterly or yearly membership partway through for a genuine reason, write to us. We will normally refund the unused whole months on a pro-rata basis. This is discretionary rather than automatic, and we would rather deal with a real situation fairly than hide behind a clause.
5. How to request a refund
Email info@calculix.in from your registered email address with:
- the payment reference or transaction ID;
- the date and amount;
- a one-line reason, so we can fix the underlying problem.
6. How long it takes
| Stage | Time |
|---|---|
| We acknowledge your request | Within 48 hours |
| We approve or explain a refusal | Within 5 working days |
| We initiate the refund with the gateway | Within 2 working days of approval |
| Money reaches your account | 5–10 working days, depending on your bank |
Refunds go back to the original payment method. We cannot send a refund to a different card, account or UPI ID — that restriction comes from the payment networks, not from us.
7. Failed payments
If money was deducted but the payment failed, it is usually reversed automatically by your bank within 5–7 working days. If it has not been after that, email us with the transaction reference and we will chase it with the gateway on your behalf.
8. If you are unhappy with our decision
Write to the same address and ask for it to be reviewed. If you remain dissatisfied you may raise the matter with your card issuer or bank, or with the appropriate consumer forum under the Consumer Protection Act, 2019.
