Terms of Service
Last updated: 28 September 2026
These terms cover your use of JSK TradeProof, an Excel add-in and Google Sheets
add-on published by JSK Business Solutions Private Limited, trading as JSKAPPS,
registered at 126/2/1 New Cord Road, Kankinara, Kolkata, West Bengal 743126, India.
By installing or using TradeProof you accept these terms. If you do not accept them, do
not install it.
What TradeProof is
TradeProof reads a list of trades that is already in your spreadsheet and writes an
analytical report into new sheets in the same file. It computes standard performance and
risk measures, and it can resample your trades to show the range of outcomes the same
record could have produced.
It is a calculator, not an adviser. See Not financial advice below, which is the
most important clause in this document.
Your licence
We grant you a personal, non-exclusive, non-transferable right to install and use
TradeProof for as long as these terms are observed.
You may use it for your own trading and for the trading of the business that bought the
licence. You may not resell it, sublicense it, rent it out, or make it available as a
service to people who have not bought their own licence.
You may not attempt to circumvent the licence check, share a key with people outside your
licence, or redistribute a modified build. A key that is used in a way these terms do not
permit may be deactivated.
One Pro licence covers both the Excel add-in and the Google Sheets add-on for the same
person or business.
Plans and payment
| Plan | Cost | What it covers |
|---|---|---|
| Instant | Free, no account | Up to 100 trades, every metric and chart, no network request at all |
| Free account | Free, sign in | Unlimited trades, portfolio of up to 3 strategies, saved mappings |
| Pro | ₹3,900 or $49, one time | The robustness suite: Monte Carlo, what-if, out-of-sample, market phases, MAE and MFE, money management, compare, unlimited portfolio, your own branding |
Pro is a one time payment, not a subscription. There is no recurring charge and
nothing to cancel.
Prices are shown inclusive or exclusive of tax as stated at checkout. You are responsible
for any tax that applies where you are, beyond what we collect.
We may change prices for future purchases. A change never affects a licence already
bought.
Trial, and why purchases are final
Every Pro feature is available free for 15 days before you pay anything. Start the
trial from your JSKAPPS account. During it you have the full robustness suite: Monte
Carlo, what-if, out-of-sample, market phases, MAE and MFE, money management and compare.
You can also run your entire trading history through the free tier at any time,
with no time limit at all, because a free account removes the 100 trade cap. Between the
two you can confirm that TradeProof reads your export correctly, that the columns map the
way you expect, and that the numbers are the ones you want, before any money changes
hands.
Because a complete trial is available before purchase, Pro purchases are final and we do
not offer refunds. Buy it after the trial has told you what you need to know, not
before.
Two things that survive that, because they should:
- If the licence does not work, meaning you paid and the Pro features did not unlock,
write to info@jskapps.com. That is a fault on our side and we will fix it or refund
you. - Statutory rights are untouched. See Consumers in the EEA and the UK below.
Consumers in the EEA and the UK
If you buy as a consumer in the European Economic Area or the United Kingdom, you normally
have 14 days to cancel a purchase of digital content and get your money back.
That right can be given up, and it is given up when you ask for immediate access. At
checkout you are asked to confirm that you want TradeProof unlocked straight away and that
you understand you give up the 14 day cancellation right by doing so. If you confirm
that, the purchase is final and the section above applies.
If you did not confirm it, the 14 day right stands, whatever the section above says.
Nothing in these terms removes a right the law gives you and does not let you waive.
Your data
TradeProof does not upload your trades. The analysis runs inside your own spreadsheet, and
the only network request the product makes is a licence check that carries your key and
nothing else. With no key entered it makes no network request at all.
What is collected, what is stored and where, is set out in full in the
Privacy Policy, which forms part of
these terms.
Not financial advice
TradeProof is for educational and analytical purposes only. Nothing it produces is
financial, investment, tax or trading advice, and nothing in it is a recommendation to
buy, sell or hold anything.
The reports describe trades you have already made. They express no opinion about what any
instrument or strategy might do next.
Some analyses, including Monte Carlo resampling, out-of-sample splits and money management
replays, are models of what could have happened under stated assumptions. They rest on
the record you supplied and on those assumptions. They are not predictions, they promise nothing,
and a result that looks favourable is not evidence that a strategy is sound.
Trading carries risk, including the risk of losing more than you put in. Past results
do not indicate future results. Decisions you make after reading a TradeProof report are
yours alone, and you are responsible for them. If you need advice, consult someone
qualified and regulated to give it.
Accuracy, and the limits of it
TradeProof computes standard measures from the data you give it. It cannot tell whether
that data is complete, correct, or mapped to the right columns, and a wrong column
produces a report that is entirely plausible and entirely wrong. The product flags the
columns it guessed so you can check them. Checking them is your responsibility.
We take care that the arithmetic is right and we test it, but we do not warrant that the
software is free of defects or that any figure is fit for a particular purpose.
Availability
TradeProof runs inside Microsoft Excel and Google Sheets, which are not ours. A change by
Microsoft or Google, or the withdrawal of a feature TradeProof relies on, can affect it in
ways we do not control.
The licence check depends on our servers being reachable. We aim to keep them available
and we do not promise any particular level of uptime. The Instant tier needs no network at
all.
Termination
You may stop using TradeProof at any time by removing it. Removing it does not delete the
report sheets already in your workbooks; those are yours and they stay where they are.
We may suspend or end a licence that is used in breach of these terms. Where the breach is
not deliberate we will tell you and give you a chance to put it right first.
Liability
Nothing in these terms limits liability for death or personal injury caused by
negligence, for fraud, or for anything else that cannot lawfully be limited.
Subject to that, and to the fullest extent the law allows:
- We are not liable for trading losses, lost profits, lost opportunity, or decisions
taken on the basis of a TradeProof report. - We are not liable for indirect or consequential loss, or for loss of data, however
caused. - Our total liability for any claim connected with TradeProof is limited to the amount
you paid us for it in the twelve months before the claim arose.
If you paid nothing, that limit is nothing. The Instant and free tiers are provided as
they are.
Changes to these terms
We may update these terms. The date at the top changes when we do. A material change is
announced on the product page before it takes effect. Continuing to use TradeProof after
that means you accept the updated terms.
Governing law
These terms are governed by the laws of India. The courts at Kolkata, West Bengal
have exclusive jurisdiction over any dispute arising from them.
If you are a consumer in the European Economic Area or the United Kingdom, this does not
remove the protection of the mandatory consumer law of the country you live in, or your
right to bring proceedings there.
