These terms are an agreement between you and me, José Donato, an individual software developer based in Portugal — throughout these terms "I" and "me" mean José Donato. You can reach me at cryexc.app@gmail.com.
You accept these terms when you confirm acceptance while connecting a wallet or enabling trading, and in any case by using the app. If you don't agree with them, don't use cryexc.
Cryexc is software: a charting and analytics interface that can also prepare transactions for you. Trading is entirely optional — you can use cryexc purely for its charts and analytics without ever connecting a wallet, and the trading-related parts of these terms only apply once you do. When you trade, the order is signed in your own browser — by your wallet, or by a session trading key you authorize with it that lives only on your device and cannot withdraw funds — and sent directly to an unaffiliated third-party venue (currently Lighter and Hyperliquid). Cryexc is one way of placing orders on those venues, not the only one — placing orders you've authorized is all it can do; it cannot manage your funds or deposit, transfer, or withdraw them.
I do not broker orders on your behalf and I do not execute, settle, or match trades — that happens entirely on the venues. I never take custody of your funds or keys, cannot access or move them, and cannot trade, cancel, or withdraw for you. I am not an exchange, broker, investment firm, or crypto-asset service provider, and neither I nor cryexc is licensed or supervised by any financial regulator.
Cryexc is non-custodial. You are solely responsible for your wallet, seed phrase, private keys, session trading keys, and the security of the device they live on. If you lose control of them, your funds can be lost permanently — neither I nor anyone else can recover them. You can revoke a session trading key or approval at any time through the venue.
Lighter and Hyperliquid are independent platforms with their own terms of service and their own restricted-jurisdiction rules. Your trading is governed by those terms — review Lighter's terms and Hyperliquid's terms before you trade. I am not responsible for what the venues do, including outages, delistings, liquidation engines, or smart-contract failures.
You are solely responsible for confirming that you are eligible to use each venue and that trading is legal where you are. By connecting a wallet you represent that you are not in a restricted jurisdiction and that you comply with your local laws and each venue's restricted-region rules. Cryexc relies on this self-attestation — asked when you connect and again during each venue's setup — and does not verify your location or identity. If you are in a restricted jurisdiction, don't use the trading features.
You must be at least 18 (or the age of majority where you live) and legally able to enter into this agreement. You must not be subject to sanctions imposed by the EU, UN, US, or any other applicable authority, and you must not use a VPN or similar tools to hide your location from a venue's restrictions.
Don't use cryexc for anything unlawful — including market manipulation such as spoofing or wash trading, laundering the proceeds of crime, or attacking, disrupting, or scraping the service. Cryexc has no accounts and runs in your browser, so I have no way to monitor or police individual users: complying with these rules is your obligation, and the venues enforce their own. I may still stop or restrict serving the app at any time if it is being abused.
Cryexc currently adds 0 bp — no fee of my own on your trades. You still pay the venue's own trading fees, which are set and charged by the venue, not by cryexc.
Setup may include one gasless, revocable approval that attributes your trading volume to cryexc. At the current 0 bp rate that approval costs you nothing — it only records that the terminal was used. If I ever introduce a cryexc fee, it will be disclosed and require your explicit in-app consent before it applies.
Everything cryexc shows — charts, order flow, analytics, alerts, signals, news — is informational only and can be wrong, stale, or incomplete. Nothing in cryexc is financial, investment, legal, or tax advice, a recommendation, or a solicitation to trade, and using cryexc creates no advisory or fiduciary relationship between us. Every trading decision is your own, and any taxes arising from your trading are your responsibility.
Cryexc is early beta software provided "as is" and "as available", with no warranties of any kind to the extent the law allows. I don't guarantee it is accurate, reliable, uninterrupted, or free of bugs. Real-time market data and order routing depend on venue APIs, WebSocket connections, and network conditions — prices shown can be stale, and orders can be delayed, rejected, or filled at a different price than the one on screen.
Trading perpetuals and other leveraged derivatives carries a high risk of loss, up to and including your entire balance. On-chain transactions are irreversible, and the venues' smart contracts and infrastructure carry their own risks. Only trade with funds you can afford to lose.
Cryexc is free software offered without any guarantee of results. To the maximum extent permitted by applicable law, I am not liable for any loss arising from your use of cryexc — including trading losses, losses caused by the venues, third-party data, software bugs, outages, network failures, and indirect or consequential losses of any kind.
Nothing in these terms excludes or limits any liability that cannot lawfully be excluded or limited — including liability for intentional misconduct or gross negligence, or for death or personal injury — and if you are a consumer, nothing in these terms takes away your mandatory statutory rights. If your breach of these terms or unlawful use of cryexc leads to a third-party claim against me, you will compensate me for the reasonable costs that result.
I keep all rights in cryexc's software, design, and branding. You get a personal, non-transferable, revocable license to use the app. Don't copy it, resell it, or pass it off as your own. Cryexc is a beta project run by one person: I may change, suspend, or discontinue the app or any feature at any time.
These terms are governed by the laws of Portugal, and disputes go to the Portuguese courts — but if you are a consumer, you also keep any mandatory protections of the law of the country where you live, including any right to bring proceedings there. If part of these terms turns out to be unenforceable, the rest still applies.
I may update these terms as cryexc evolves; the "last updated" date above reflects the current version. For material changes that affect trading, you'll be notified in the app and asked to accept again before continuing to trade; minor changes apply when posted.
