Terms of Service

These Terms of Service (the “Terms”) form a binding contract between you and FP System LLC, a Delaware limited liability company (“iStealth”, “we”, “us”, or “our”), that governs your access to and use of the iStealth desktop browser, launcher, website at fpsystem.us, APIs, and any related services (together, the “Service”).

These Terms incorporate our Privacy Policy and Acceptable Use Policy by reference. In the event of a conflict, the Acceptable Use Policy controls matters of permitted/prohibited conduct, the Privacy Policy controls matters of personal-data handling, and these Terms control everything else.

By installing, launching, or otherwise using the Service, you accept these Terms on your own behalf and on behalf of any organization for which you act. If you do not agree, do not use the Service.

• You must be at least 18 years of age, or the age of majority in your jurisdiction if higher.
• You must not be located in, ordinarily resident in, or organized under the laws of any country subject to comprehensive US sanctions (Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions of Ukraine, as of the effective date of these Terms), nor appear on any US restricted-party list.
• At launch, account registration is available only to residents of the United States. Access from other jurisdictions is a roadmap item.
• You represent that you are capable of forming a binding contract and that your use of the Service does not violate any law applicable to you.

• To purchase a license or download the launcher, you must register an account with a valid email. We verify ownership of the email via a one-time code before activating the account.
• You are responsible for safeguarding your password, session tokens, and license keys. You must notify us immediately at [email protected] of any actual or suspected unauthorized use.
• You must keep your account information current. We may suspend or terminate the account if information is materially inaccurate.
• One natural person per account. Sharing a single account among multiple users is prohibited. For collaboration, use the team invitation system under your Pro plan.

Subject to your continuing compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and run the iStealth launcher and browser on Mac computers you own or control, solely for the purposes permitted by your plan and the Acceptable Use Policy.

• The license does not convey any ownership of the Service.
• You may not assign or transfer the license or your account to another person or entity except through our in-product team invitation system.
• You may not use the Service to build or operate a competing product, to reverse engineer the launcher or browser, or to extract cryptographic material — except to the minimum extent expressly permitted by applicable law that cannot be disclaimed (for example, EU Directive 2009/24/EC Article 6 interoperability).

Your use of the Service is at all times subject to our Acceptable Use Policy (AUP). The AUP forms an integral part of these Terms. Any violation of the AUP is a breach of these Terms and grounds for immediate suspension or termination.

• iStealth plans are billed on a monthly subscription basis, prepaid in cryptocurrency via our non-custodial payment processor. Prices in USD are shown on the pricing page and include network/processing fees only as indicated.
• Your license is active from the date of confirmed payment until the end of the billing period (30 days from payment unless stated otherwise).
• Price changes take effect on the next renewal. We will post changes on the pricing page; continued use after the effective date is acceptance of the new price.
• Because payments are settled in crypto, the exact fiat value received may differ by a small amount from the displayed USD price due to exchange-rate movement. We will not hold you to a shortfall of 2% or less; larger shortfalls will be flagged for top-up.
• Taxes: you are responsible for any VAT, sales, or use tax that applies to your jurisdiction. Where required by law, we will collect and remit such taxes.

• Subscriptions do not auto-renew. At the end of your billing period, access ends until you renew manually via the Dashboard.
• You may upgrade or downgrade between Starter / Medium / Pro at any time. Upgrades prorate the difference and extend access through the end of the current period. Downgrades take effect at the next renewal.
• You may stop using the Service at any time. Because subscriptions do not auto-renew, no cancellation request is required; simply do not renew.

• Crypto payments are final. Once the blockchain transaction confirms and your license activates, the subscription cannot be refunded as a matter of course.
• In the event of a technical failure on our side that prevents you from using the Service for an extended period, contact [email protected] and we will work with you in good faith.
• We do not refund subscriptions terminated for AUP violation.

• Upon first activation, your license binds to the hardware serial of your Mac (HWID). After binding, attempts to activate on a different device are refused.
• If you switch Macs (new purchase, motherboard replacement, stolen laptop), contact support for a one-time HWID reset. We may ask for proof of device ownership at our discretion.
• You may not invalidate HWID binding by reinstalling macOS, cloning a disk image, altering the serial number, or running the launcher in a VM configured to mimic another machine.

• Pro plans may invite additional users ("workers") to share profile pools, subject to per-seat billing as shown in the launcher. Workers must each have their own iStealth account and accept these Terms independently.
• The Pro owner is jointly and severally responsible for every act and omission of every worker operating under their license, including violations of the AUP.
• The Pro owner may remove a worker at any time. Removal revokes the worker's access to the owner's profile pool immediately.
• We may remove a worker independently of the owner if the worker violates the AUP or these Terms.

• The launcher and browser engine are updated periodically with security patches, fingerprint refinements, and new features. We may push updates through the launcher's in-app update channel.
• Some updates are required (security). Continued use of the Service may require installing a required update.
• We may add, remove, or modify features at any time. Material changes that remove plan functionality will be announced at least 14 days in advance where commercially reasonable.

• Email support is included in all paid plans. We target a response within two business days.
• We do not guarantee a fix on any particular timeline. Urgent support targets and SLAs are part of Enterprise contracts.
• We are not obliged to support uses that fall outside the AUP or that require technical reconfiguration of your local environment, corporate MDM, or operating system beyond documented installation steps.

The Service, the iStealth name and logos, the launcher, the browser engine fork, associated documentation, and all underlying source code remain the sole property of FP System LLC and its licensors. No license is granted by implication, estoppel, or otherwise, except as expressly set out in Section 4.

Your browsing history, cookies, saved passwords, and other data stored within profiles remain yours. We process them only to provide the Service and only as described in the Privacy Policy.

We respond to notices under the Digital Millennium Copyright Act (17 U.S.C. § 512). Send properly formatted notices to [email protected].

The Service integrates with third parties you may interact with directly or indirectly:

• Resend — transactional email delivery (OTP, password reset). Subject to Resend's terms.
• CryptAPI.io — non-custodial cryptocurrency payment routing. Funds move from your wallet to our merchant addresses without our ever holding them. Subject to CryptAPI's terms.
• Third-party websites you visit with the browser set their own terms, which you are responsible for respecting.

We are not responsible for third-party services. Their failure, downtime, or changes to their own terms are outside our control and do not entitle you to a refund of your iStealth subscription.

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. To the maximum extent permitted by law, we disclaim all warranties including merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that the Service will be uninterrupted, error-free, free of malicious code introduced by third parties, or that it will remain compatible with every current or future detection method used by any third-party platform. Detection technology evolves; no multi-account browser can guarantee perpetual compatibility with every platform's checks.

Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions, our warranties are limited to the minimum period required by law.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL FP SYSTEM LLC OR ITS OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES (including loss of profits, loss of data, loss of goodwill, or business interruption) arising out of or relating to your use of the Service, whether based in contract, tort, strict liability, or any other theory, and whether or not we have been advised of the possibility of such damages.

Our aggregate liability to you for all claims arising out of or relating to the Service is limited to the greater of (a) the amount you paid us in the twelve months before the event giving rise to the claim, or (b) one hundred US dollars ($100).

Some jurisdictions do not allow the limitation of liability for certain damages (e.g., gross negligence, willful misconduct, death or personal injury); the above limits do not apply to those categories and apply only to the extent permitted by law.

You agree to defend, indemnify, and hold harmless FP System LLC, its affiliates, officers, directors, employees, contractors, and licensors from and against any third-party claims, demands, losses, liabilities, damages, judgments, settlements, and costs (including reasonable attorneys' fees) arising out of or relating to:

• your breach of these Terms or any incorporated policy;
• your violation of any applicable law or third-party right;
• any act or omission of any person operating under your license or team invitation;
• any content you upload, transmit, or process through the Service.

• By you. You may stop using the Service at any time. Letting a subscription lapse terminates your license at the end of the paid period.
• By us. We may suspend or terminate your account, license, or access to the Service at any time, with or without notice, for conduct that breaches these Terms or the AUP, for failure to pay, for fraudulent activity, or for any other reason where continuing the relationship would expose us to legal or reputational risk.
• Effect of termination. Upon termination: (a) your license is revoked, (b) you must uninstall the launcher and browser and delete associated local data, (c) we may delete your encrypted profile blobs, history, and passwords from our servers after a reasonable retention period.
• Sections that by their nature should survive — including 13 (IP), 15 (warranty), 16 (liability), 17 (indemnification), 19 (disputes), 20 (governing law), and 21 (general provisions) — survive termination.

Informal resolution first. Before filing any formal action, you must contact us at [email protected] with a written description of the dispute and your requested relief. We will attempt to resolve the dispute informally within thirty (30) days.

Binding arbitration. If informal resolution fails, any dispute arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules and, where applicable, the Consumer Arbitration Rules. The seat of arbitration is Wilmington, Delaware. The Federal Arbitration Act (9 U.S.C. §§ 1 et seq.) governs the interpretation and enforcement of this provision.

Class-action waiver. You and we agree that each may bring claims against the other only in an individual capacity and not as a plaintiff or class member in any purported class, collective, or representative action. The arbitrator may not consolidate more than one person's claims and may not preside over any form of a representative or class proceeding.

Carve-outs. The arbitration requirement does not apply to (a) claims for injunctive or other equitable relief, (b) claims for intellectual-property infringement, (c) small-claims-court actions, or (d) matters that are non-arbitrable as a matter of law.

Opt-out. You may opt out of this arbitration provision by sending written notice to [email protected] within 30 days of first accepting these Terms. Your notice must include your full name, the email associated with your account, and a clear statement that you are opting out of arbitration. Opting out does not affect any other provision of these Terms.

These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-laws principles and excluding the UN Convention on Contracts for the International Sale of Goods. Any action not subject to arbitration must be brought exclusively in the state or federal courts located in New Castle County, Delaware, and you consent to personal jurisdiction and venue in those courts.

Where a provision of these Terms conflicts with a mandatory, non-disclaimable provision of the law of your residence, the mandatory provision prevails only to the minimum extent required.

• Entire agreement. These Terms, together with the AUP and Privacy Policy, constitute the entire agreement between you and us regarding the Service and supersede any prior or contemporaneous communications.
• Severability. If any provision is held unenforceable, that provision will be modified to the minimum extent needed to make it enforceable, or severed, with the remaining provisions continuing in full force.
• No waiver. Our failure to enforce any right is not a waiver of that right.
• Assignment. You may not assign these Terms without our prior written consent. We may assign them freely in connection with a merger, acquisition, or sale of assets.
• Force majeure. Neither party is liable for failures caused by events beyond reasonable control (natural disasters, war, civil unrest, changes in law, pandemic, ISP or cloud-provider failure, widespread network outage).
• Notices. We may send notices to the email on file for your account. You must send formal notices to [email protected].
• Export. The Service is subject to US export controls. You must not export, re-export, or transfer it in violation of applicable law.
• Language. The authoritative version of these Terms is English. Translations are provided for convenience.
