Acceptable Use Policy
Last updated: April 23, 2026 · Effective date: April 23, 2026
1. Introduction
This Acceptable Use Policy (the “AUP”) governs your access to and use of iStealth, a desktop browser product published by FP System LLC, a Delaware limited liability company (“iStealth”, “we”, “us”, or “our”). The AUP is a binding part of the agreement between you and us and is incorporated by reference into our Terms of Service and Privacy Policy. In the event of a conflict between the AUP and our Terms of Service, the Terms of Service control except with respect to matters of acceptable use, in which case this AUP controls.
By downloading, installing, activating, or otherwise using iStealth, you represent that you have read, understood, and agree to this AUP on your own behalf and on behalf of any organization you represent. If you cannot agree, do not install or use the product; uninstall it if already installed and contact us for license cancellation where applicable.
The rules below are not exhaustive. We retain the right, in our reasonable discretion, to treat conduct that is materially similar to the enumerated categories as a violation of this AUP.
2. Who this applies to
This AUP applies to every person and entity that:
- purchases, receives, or otherwise holds an iStealth license;
- accesses iStealth on behalf of an organization;
- is invited as a team member or “worker” under another license;
- accesses the iStealth website, APIs, downloads, or any related service.
License owners are responsible for every act and omission of every team member, worker, contractor, or agent operating under their license, and agree to hold us harmless on that basis in accordance with Section 11 (Indemnification).
3. Who may not use iStealth
- Minors. Anyone under 18, or under the legal age of majority in their jurisdiction, whichever is higher. We do not knowingly collect information from children under 13, in accordance with the Children’s Online Privacy Protection Act (COPPA), 15 U.S.C. §§ 6501–6506.
- Sanctioned countries and regions. Any person or entity located in, ordinarily resident in, or organized under the laws of a country or territory subject to comprehensive US sanctions administered by the Office of Foreign Assets Control (OFAC), as of the effective date this includes Cuba, Iran, the Democratic People’s Republic of Korea (North Korea), Syria, and the Crimea, so-called Donetsk People’s Republic, and so-called Luhansk People’s Republic regions of Ukraine, plus any area subsequently added by OFAC to the comprehensive sanctions list.
- Restricted parties. Any person or entity on the OFAC Specially Designated Nationals (SDN) list, the Consolidated Sanctions List, the Sectoral Sanctions Identification List, the Bureau of Industry and Security (BIS) Denied Persons List, the BIS Entity List, the BIS Unverified List, the Defense Trade Controls Debarred List, or any equivalent list maintained by the US, UK, EU, UN, or other relevant authority.
- Export-barred parties. Any person or entity barred from receiving US-origin goods, services, or technology under the Export Administration Regulations (15 C.F.R. Parts 730–774) or the International Traffic in Arms Regulations (22 C.F.R. Parts 120–130).
- Previously terminated users. Anyone previously terminated by iStealth for a violation of this AUP, unless expressly reinstated by us in writing.
You represent and warrant at the time you activate and each time you use iStealth that you fall into none of the above categories and that your use is not prohibited by the laws of any jurisdiction to which you are subject.
4. Permitted uses
iStealth is a privacy-preserving browser. Many lawful, legitimate activities benefit from isolated browser identities. The following are examples of permitted use, not an exhaustive catalog:
- Personal privacy. Keeping your personal, work, and public-facing browsing segregated; minimizing cross-site tracking of lawful activity.
- E-commerce operations. Managing multiple storefronts, seller accounts, or marketplaces you own or are authorized to operate, in full compliance with each platform’s terms of service and applicable tax and consumer-protection law.
- Affiliate and performance marketing. Running campaigns you are authorized to run, using creatives and landing pages you have the right to use, with honest disclosures required by the FTC’s Endorsement Guides (16 C.F.R. Part 255).
- Ad verification and competitive research. Verifying how your own ads are served, confirming geo-targeting, and monitoring competitors using only publicly available information in accordance with applicable law, including hiQ Labs v. LinkedIn and its progeny.
- Web testing, QA, and application security. Testing sites and applications you own, or are engaged in writing to test with the owner’s prior written authorization.
- Journalism, academic research, and advocacy. Investigative reporting, academic research conducted with institutional approval, digital-rights advocacy, and lawful whistle-blowing activity.
- Authorized security testing. Red-team or penetration-testing engagements conducted with prior written authorization from the system owner and within the authorization’s scope.
- Protection from stalking, harassment, or intimate-partner violence. Reducing the chance of being tracked online by a known abuser.
- Brand protection. Monitoring infringement, counterfeiting, phishing, or impersonation targeting your own brand, pursuant to rights you hold under US trademark and copyright law.
Appearance in this list does not confer immunity from any other law, regulation, or third-party contract.
5. Prohibited uses
You may not use iStealth, and you may not allow any person acting under your license to use iStealth, for any activity prohibited by applicable law. Prohibited categories include, but are not limited to: financial crime, unauthorized access to computer systems, identity theft, money laundering, violation of sanctions programs, tax evasion, privacy-law violations, harassment or harm to persons, trafficking in illegal goods or services, abuse of iStealth's infrastructure, and infringement of intellectual-property rights.
You are solely responsible for compliance with all applicable laws and with the terms of any third-party platform you access through iStealth. Violations result in immediate license termination without refund and may be reported to law enforcement.

6. Use with third-party platforms
iStealth connects you to third-party websites, platforms, and services. Each of those third parties sets its own terms of service, acceptable-use policy, automation rules, and multi-account rules. Nothing in this AUP grants you permission to violate a third-party platform’s terms, and nothing in iStealth’s technical design confers immunity from a platform’s enforcement, civil claims (including under the CFAA on a contract-breach theory), or criminal liability.
Managing multiple identities on a platform is permissible under this AUP only to the extent the platform itself permits it. If a platform forbids multiple accounts, forbids automation, forbids specific activities, or limits account ownership to one per natural person, you must respect those rules.
Where a platform, account, or data set is not publicly accessible, you must have express authorization from the rights-holder before accessing it with iStealth.
7. Intellectual property
iStealth, the iStealth word mark, associated logos, the iStealth website, launcher, icons, documentation, and the iStealth cloud-sync blobs are the intellectual property of FP System LLC and its licensors. Nothing in this AUP grants you any right, title, or interest in any of the foregoing except the limited, non-exclusive, non-transferable license to use iStealth in accordance with our Terms of Service.
We respond to notices alleging copyright infringement under the Digital Millennium Copyright Act (17 U.S.C. § 512). Properly formatted notices should be sent to [email protected]. Repeat infringers will be terminated.
8. Export controls and sanctions compliance
iStealth is subject to US export-control laws, including the Export Administration Regulations (EAR) and economic sanctions administered by OFAC. You represent and warrant that:
- you are not located in, organized under the laws of, or ordinarily resident in a country or region subject to comprehensive US sanctions;
- you are not on any US or allied-jurisdiction restricted-party list; and
- you will not directly or indirectly export, re-export, transfer, or divert iStealth to any prohibited destination, party, or end-use (including WMD, military-intelligence, or human-rights violation end-uses under 15 C.F.R. § 744).
You agree to cooperate with us in connection with any inquiry, audit, or request for information arising out of export-control or sanctions compliance.
9. Reporting violations
If you believe someone is using iStealth in violation of this AUP, or you are law enforcement, a regulator, a platform trust & safety team, or a rights-holder with a formal request, contact us at the addresses below. Please include enough information for us to investigate — license key where known, timestamps (UTC preferred), URLs, and supporting evidence.
- Abuse reports: [email protected]
- Law-enforcement and regulatory requests: [email protected]
- Copyright / DMCA notices: [email protected]
- Security vulnerabilities in iStealth itself: [email protected]
We respond to validly served subpoenas, court orders, and search warrants in accordance with applicable law. We may notify affected users of a legal request unless prohibited from doing so by law or a court order.
10. Enforcement and consequences
If we reasonably believe you have violated this AUP, we may take any one or more of the following actions, at our discretion and without prior notice where prompt action is necessary to protect us, our users, or third parties:
- Issue a warning, request information, or require remediation as a condition of continued use.
- Suspend or terminate your license, your team memberships, your account, your download access, or your access to updates, without refund for the period in which the violation occurred.
- Preserve, collect, or disclose information as required by valid legal process, a good-faith belief of imminent harm, or in support of lawful law-enforcement or regulatory investigations.
- Cooperate with law-enforcement investigations, regulators, and rights-holder subpoenas served with appropriate legal process.
- Pursue civil remedies, including injunctive relief, damages (including liquidated damages where provided), disgorgement of profits, and recovery of costs and reasonable attorneys’ fees.
Our failure to enforce any provision of this AUP at any time is not a waiver of our right to enforce it later.
11. Indemnification
You agree to defend, indemnify, and hold harmless FP System LLC, its affiliates, officers, directors, employees, contractors, and licensors (the “Indemnified Parties”) from and against any and all third-party claims, demands, losses, liabilities, damages, judgments, settlements, and costs (including reasonable attorneys’ fees and court costs) arising out of or relating to:
- your breach of this AUP or our Terms of Service;
- your violation of any law, regulation, or third-party right;
- any act or omission of any person operating under your license, team invitation, or worker seat;
- any content you upload, transmit, or process through iStealth.
We reserve the right, at our own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, in which case you agree to cooperate with our defense.
12. Modifications to this policy
We may update this AUP from time to time to reflect changes in our services, applicable law, or best practice. Material changes will be announced on our website with a new “Last updated” date at the top of this page. Your continued use of iStealth after the effective date of a change constitutes acceptance of the revised policy. If you do not agree with a change, your sole remedy is to stop using iStealth and uninstall the product.
13. Governing law, venue, and dispute resolution
This AUP is governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws principles and excluding the UN Convention on Contracts for the International Sale of Goods.
Arbitration. Except for (a) claims for injunctive or other equitable relief, (b) claims for intellectual property infringement, (c) small-claims-court actions, and (d) matters that are non-arbitrable as a matter of law, any dispute arising out of or relating to this AUP or your use of iStealth shall 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.
Venue for non-arbitrable matters. Any action that is not subject to arbitration shall 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.
14. No waiver of user rights
Nothing in this AUP waives any right you have under applicable consumer-protection, privacy, antidiscrimination, or whistle-blower-protection law. Nothing prevents you from reporting misconduct to a government authority, testifying under oath, cooperating with a regulator, or exercising any right protected by 18 U.S.C. § 1833 (DTSA whistle-blower immunity) or 5 U.S.C. § 2302(b).
Where a provision of this AUP conflicts with a mandatory, non-disclaimable provision of the law of your residence, the mandatory provision prevails only to the minimum extent required.
15. Severability, survival, and entire agreement
Severability. If any provision of this AUP is held by a court of competent jurisdiction to be invalid, unenforceable, or contrary to law, that provision shall be modified to the minimum extent necessary to make it enforceable, or, if that is not possible, severed, and the remaining provisions shall remain in full force and effect.
Survival. Sections that by their nature should survive termination — including Sections 7 (Intellectual Property), 10 (Enforcement), 11 (Indemnification), 13 (Governing Law), and 15 — survive termination of your access to iStealth.
Entire agreement. This AUP, together with our Terms of Service and Privacy Policy and any order form or license key you have accepted, constitutes the entire agreement between you and FP System LLC regarding acceptable use of iStealth and supersedes any prior or contemporaneous communications on the subject.
