Licence agreement

1. What you are licensed to do

Your subscription buys a personal, non-exclusive, non-transferable licence to install Chartveil on as many of your own computers as you like, and to run it on the number your plan allows at the same time — one copy on the monthly plan, two on the annual plan — for as long as the subscription is active and paid.

The limit is on simultaneous use, not on installation. Opening a copy beyond that number is not a breach of this licence and does not need anyone’s permission: the software simply closes whichever copy has been running longest. What the licence is personal to is you — your own computers means computers you use, not a desk of colleagues, a trading room or a household.

You are buying access to software, not the software itself. Chartveil, its source code, its studies and its interface remain ours. Nothing here transfers ownership of any part of it.

2. What you must not do

You agree that you will not, and will not help or pay anyone else to:

• Copy or distribute the software — upload it, share the installer, post it, seed it, or hand it to anyone who has not bought their own licence
• Share your licence — give out, sell, rent, lend or publish your licence key or account credentials, or let another person use them
• Resell or sublicence access, or run the software as a service for other people, without a separate written agreement with us
• Reverse engineer — decompile, disassemble, deobfuscate, unpack or otherwise try to recover source code, algorithms or the design of any part of it
• Defeat the licensing — patch, crack, emulate, bypass or disable the licence check, the activation, the seat limits or any update or integrity mechanism; run a modified or cracked build; or feed the licence server false information
• Attack the service — probe, scan or attempt unauthorised access to our servers, licence API, accounts or infrastructure
• Strip attribution — remove or alter any copyright notice, mark or licence text in the software
• Redistribute market data received through the software

3. The licence check is a protection measure

Chartveil's activation and licence verification are technological measures that control access to copyrighted work. Circumventing them, or making, sharing or using a tool whose purpose is to circumvent them, is not merely a breach of this agreement — it is a separate violation of anti-circumvention law, including 17 U.S.C. § 1201 in the United States and its equivalents elsewhere. That claim stands on its own, whether or not any copying is proved.

4. What happens if you break this

These are consequences, not threats, and they are set out so that nobody can say they were not told:

• Your licence ends immediately, automatically and without notice, the moment you breach clause 2. The software stops working at the next check.
• No refund. All sales are final in any case; termination for breach does not create one, and no part of the period you have paid for is returned.
• You may not come back. We may refuse to sell to you again, and may close any other account we reasonably link to you.
• You are liable for the loss. That includes our list-price fee for every unlicensed copy made, used or distributed through your breach, our reasonable costs of investigating and enforcing, and legal fees where the law allows them to be recovered.
• Statutory damages may apply. Copyright infringement and circumvention both carry damages set by statute, awarded per work or per act rather than by what we can show we lost.
• We may seek an injunction to stop continuing distribution, in addition to damages, without having to prove money loss first.

Your account is responsible for what is done with your licence key. If you hand it out, what follows is treated as your breach — so keep it to yourself.

5. What we record, and why

Activations are logged: the licence key, an anonymised machine identifier, a device label, the version and the time. We use that to enforce seat limits and to detect sharing, and we may rely on it as evidence. We do not collect your market-data credentials, your positions or your trading history — see the privacy policy.

If a licence is being used in a way that looks like sharing or circumvention, we may suspend it while we look. If we were wrong, we turn it straight back on and add the lost days.

6. Where the law overrides this

Nothing in clause 2 restricts anything you have a legal right to do that cannot be signed away. In particular, where the law where you live gives a lawful user the right to decompile or study the software to achieve interoperability with other programs — as it does in the European Union — that right stands, and this agreement does not limit it. Ask us first: if the information is available for the asking, we would rather hand it over.

If any part of this agreement is held unenforceable, the rest continues in force.

7. Honest mistakes

If you have already done something in clause 2 — passed your key to a colleague, put the software on a shared trading desk — email trung@chartveil.com and say so before we find it. We would far rather sell you a second licence than argue about the first one.

8. Term, governing law and contact

This licence runs for as long as your subscription is active, and ends when the subscription ends or when clause 4 terminates it. Clauses 1, 4, 5 and 6 survive it.

It is governed by the laws of the State of California, United States, and is read together with the terms of service. Questions: trung@chartveil.com.
