Last updated August 28, 2026. Operator: NetForge. Product: PIIRUS. These Terms control over marketing copy, help text, and the in-app disclaimer.
1. Agreement; parties; acceptance
These Terms of Service (the “Terms”) are a legally binding agreement between you (“you” or “Customer”) and NetForge, the operator of PIIRUS (“NetForge,” “we,” “us,” or “our”). They govern access to and use of: (a) the websites at piir.us, piirus.com, and any successor or related sites we operate (the “Site”); (b) accounts, checkout, downloads, and related online services (the “Online Services”); and (c) the PIIRUS Windows software, including EZ Mode, Expert Mode, updates, and documentation (the “Software”). The Site, Online Services, and Software are the “Service.”
You accept these Terms by any of the following, whichever occurs first: creating an account; checking an acceptance box; completing a purchase; downloading or installing the Software; signing in to the desktop app; or otherwise using the Service. Electronic acceptance has the same force as a signed writing.
If you use the Service on behalf of another person or entity, you represent that you have authority to bind that person or entity, and “you” includes both of you. If you lack that authority, you may not use the Service.
2. Definitions
Additional defined terms:
- “Account” means the login we issue or you create on the Site.
- “Device” means a single Windows computer on which the Software is installed or run.
- “Seat” or “License” means a paid right to run the Software on one Device for the License Term.
- “License Term” means one (1) year from the purchase date of that Seat, unless we state otherwise at checkout.
- “Order” means your request to buy one or more Seats through the Site, including quantity and any volume discount then offered.
- “Payment Processor” means Square and any successor payment vendor we use.
- “Content” means text, software, trademarks, screenshots, documentation, and other material on or in the Service.
Headings are for convenience only and do not affect interpretation. “Including” means “including without limitation.”
3. Eligibility; prohibited users
You must be at least 18 years old and able to form a contract. You may not use the Service if you are: (a) on any U.S. or allied sanctions or denied-party list; (b) located in a comprehensively embargoed jurisdiction; or (c) using the Service in violation of export, computer-crime, or similar law. The Software is a commercial item for U.S. Government users, licensed only under these Terms, not under any FAR or DFARS clause that would expand your rights.
4. What PIIRUS is — and is not
PIIRUS is anti-scam software for Windows. It is designed to reduce, not eliminate, risk from tech-support scams, unauthorized remote-access tools, scare-page overlays, clipboard bait, and related abuse. It is a threat-reduction tool.
PIIRUS is not: antivirus; anti-malware sufficient as your only defense; a firewall; an intrusion-prevention system; a backup product; identity-theft insurance; legal advice; a monitoring service we staff 24/7; emergency services; or a guarantee that a scammer, overlay, remote tool, PUP, or browser will be detected, blocked, or stopped. Windows Security, your ISP, your browser, and other software remain your responsibility.
The Service is offered as an early / beta product (including “Beta Release 2.0.0” and later labeled builds). Features may change, lag, fail, false-positive, false-negative, or be withdrawn. Marketing, screenshots, and “what PIIRUS does” copy are illustrations, not specifications and not warranties.
We may, without liability: modify the Software; replace a build; change detection lists; disable a feature; or require an update as a condition of continued use.
5. Accounts; security; your responsibility
An Account is required to buy, download, and sign in to the Software. You must provide accurate information and keep it current. You are solely responsible for: (a) the confidentiality of your password and any recovery email; (b) all activity on the Account, including every Device that signs in; and (c) promptly notifying us at support@piir.us of unauthorized access.
We may refuse, reclaim, or merge usernames and may suspend an Account that we reasonably believe is compromised, abusive, fraudulent, or associated with a chargeback. We are not obligated to look behind the login. A person with your credentials is you for purposes of the Service.
6. License grant; seats; term; restrictions
Subject to these Terms and timely payment, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and run the Software on one (1) Device per paid Seat during that Seat’s License Term, solely for lawful protection of Devices you own or are authorized to administer.
Signing in to the desktop app on a Device consumes one Seat for that Device. You may remove a computer from the dashboard (or equivalent) and sign in on a replacement Device, subject to our technical limits and anti-abuse controls. Seats do not include extra copies “just in case,” virtualization farms, or sharing an Account across a household beyond the Seats you bought.
Except as the license above expressly allows, you shall not, and shall not permit anyone to: (a) copy, modify, or create derivative works of the Software; (b) reverse engineer, decompile, or attempt to extract source code, detection lists, or models except to the limited extent a statute forbids this restriction; (c) rent, resell, timeshare, or provide the Software as a service to third parties; (d) circumvent license, seat, or machine-ID controls; (e) probe, flood, or disrupt the Site or Online Services; (f) use the Service to harm a person or system you are not authorized to control; or (g) remove proprietary notices.
All rights not expressly granted are reserved to NetForge and its licensors. The Software is licensed, not sold. No title to intellectual property passes to you.
7. Orders; price; taxes; Payment Processor
Current standard price is $39.95 per Seat per License Term for Piirus License, unless we display a different price at checkout. We may change prices for future Orders at any time. Displayed prices are in U.S. dollars unless marked otherwise.
10% off an order of 5 or more. Volume terms apply only to a single Order that meets the quantity threshold at the time of payment. They do not apply retroactively, do not stack with unpublished coupons unless we say so in writing, and may be modified for future Orders.
You authorize us and the Payment Processor to charge the payment method you present for the Order total, including applicable taxes and any volume adjustment. Square (or its successor) processes card data on its checkout page. We do not store full card numbers. Square’s terms also apply to the payment transaction. A successful charge is not a warranty that a download or Seat assignment will be instantaneous if our systems or yours are unavailable.
You are responsible for any sales, use, VAT, GST, or similar tax that a taxing authority assesses on your Order, except taxes on our net income. If we are required to collect tax, we may add it to the Order or invoice you later.
Orders are offers to buy. We may reject or cancel an Order for suspected fraud, pricing error, unavailability, or legal risk. If we cancel after charge, we will refund the affected amount through the Payment Processor’s ordinary path.
8. Refunds; failed charges; chargebacks
Except where a non-waivable law requires otherwise, all sales are final. Yearly Seats are not refundable because you “changed your mind,” unused the Software, or experienced a scam that the Software did not stop.
If a charge failed, duplicated, or was taken in error, email support@piir.us from the Account email used at checkout, with the approximate time and amount. We will investigate in good faith and, if we confirm error, refund or reverse through the Payment Processor.
Initiating a chargeback without first contacting us, or charging back a valid Order, is a material breach. We may suspend the Account and Seats pending resolution. You remain responsible for unpaid amounts and our reasonable costs of collection, including processor fees assessed to us because of the dispute, to the extent permitted by law.
Licenses are non-transferable except as these Terms allow when you release a Device and sign in on another Device on the same Account. You may not sell, gift, or assign Seats except with our prior written consent.
9. Downloads; builds; no public links
Paid Accounts may download the then-current Windows build from the dashboard or another path we designate. There are no public download links. We may replace a build at any time. You are responsible for installing on a compatible, licensed copy of Windows, for admin rights, and for not running the installer from an untrusted source.
We do not warrant that a particular build will remain available, that it will run on every Windows SKU or insider preview, or that an older build will be offered after we ship a newer one. You should keep your own backup of a downloaded installer if you need a known version; we are not an archive service.
10. Operation of the Software; your authority over the Device
You are solely responsible for how the Software is configured and used on each Device, including Close Program, Uninstall, process termination, blocking remote tools from launching, Lockdown / Protection, Mark As Safe, overlays, clipboard watching, Fast User Switching behavior, history, network view, and Family Alert.
By running those functions you represent that you are the owner of the Device or have the owner’s authorization, and that terminating processes, blocking software, or deleting installers will not violate a third party’s rights or your employer’s policies. Close Program and related actions may stop legitimate software, including tools you or a technician installed. You assume that risk.
Mark As Safe. Only mark a program as safe if you installed it on purpose and accept that PIIRUS may then treat it as trusted. A wrong “safe” mark can allow a remote tool or PUP to run. That is your decision and your liability, not ours.
False positives and missed detections. Detection is probabilistic. The Software may flag benign software, miss a remote, miss a scare page, treat video fullscreen incorrectly, or fail if Windows, a driver, or another program interferes. You must not rely on PIIRUS as your only control when money, credentials, or an elderly or vulnerable user are at risk. Stay on the call, verify identity independently, and use other defenses.
11. Family Alert and electronic communications
If you enable Family Alert (or a similar notification feature), the Software may email an address you enter when specified events occur (for example, a remote starts, protection is turned off, lockdown is used, or suspicious clipboard text is seen). A message may include the event type, Device name, and any phone number you typed.
You represent that: (a) you have the recipient’s consent to send those messages; (b) the address is accurate; and (c) you will not use the feature to harass, stalk, or surveil a person who has not agreed. Delivery is not guaranteed. Mail can fail, land in spam, be delayed, or be read by others with access to that inbox. We are not responsible for a missed alert, a false alert, or what the recipient does or fails to do.
You consent to receive operational mail from us at your Account email (receipts, license notices, security, and material changes to these Terms). Marketing mail, if any, will honor applicable unsubscribe law.
12. Acceptable use
You shall not use the Service to: attack, disrupt, or gain unauthorized access to any system; conceal unlawful activity; impersonate us or Square; scrape the Site with abusive automation; resell Seats; test the Software against third-party systems you do not own without permission; or operate PIIRUS as a service bureau. You shall comply with U.S. and other applicable computer-fraud, wire-fraud, and consumer-protection laws. We may report suspected crimes.
13. Data; local processing; privacy
Our Privacy Policy describes what the Site and Account systems store. Settings, safe lists, history, PIN hashes, and Family Alert contacts that remain in your Windows user profile are under your control. We do not receive your full history log or clipboard contents unless a feature you enable transmits an event (for example Family Alert). You are responsible for the Device’s physical security, disk encryption, and who can open the Windows profile.
Machine ID and a computer name are sent when the desktop app signs in so we can count Seats. You must not spoof, rotate, or clone machine IDs to evade Seat limits.
14. Third-party software, sites, and brands
The Software may name or detect third-party remote tools, browsers, and other applications. Those names are for identification. We are not affiliated with, endorsed by, or responsible for AnyDesk, TeamViewer, Microsoft, Google, or any other vendor whose software PIIRUS may flag or close. Their terms govern their products. Closing or blocking a third-party tool may violate that tool’s terms as between you and that vendor; that risk is yours.
Outbound links on the Site are provided for convenience. We do not control third-party sites, including Square’s checkout.
15. Intellectual property; feedback
The Service, including the PIIRUS name, shield artwork, wordmark, UI, detection logic, and documentation, is owned by NetForge or its licensors and is protected by copyright, trademark, and other law. No license to our marks is granted except the limited right to identify that you use PIIRUS, in ordinary factual language, without implying sponsorship.
If you send ideas, bug reports, or suggested features (“Feedback”), you grant us a perpetual, worldwide, irrevocable, royalty-free license to use that Feedback for any purpose without accounting to you. Do not send anything you do not have the right to license.
16. Export; sanctions
The Software may be subject to U.S. export-control and sanctions laws. You shall not export, re-export, or use it in violation of those laws, including in embargoed jurisdictions or by prohibited parties. You represent that you are not such a party and are not using the Service for a prohibited end use.
17. High-risk and emergency use
The Service is not designed for life-support, emergency dispatch, 911, medical devices, or any use where failure could cause death, personal injury, or severe environmental or property damage. You shall not use it for those purposes. PIIRUS does not contact law enforcement or your bank for you.
18. Disclaimer of warranties
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS. NETFORGE DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, AND NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.
WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT: (A) THE SOFTWARE WILL DETECT, BLOCK, OR TERMINATE ANY PARTICULAR REMOTE TOOL, SCARE PAGE, CLIPBOARD PAYLOAD, PUP, BROWSER, OR SCAM; (B) ALERTS, EMAIL, OR CHECKOUT WILL BE UNINTERRUPTED, TIMELY, OR ERROR-FREE; (C) DEFECTS WILL BE CORRECTED; OR (D) THE SERVICE WILL MEET YOUR REQUIREMENTS OR WORK IN COMBINATION WITH YOUR HARDWARE, WINDOWS BUILD, OR OTHER SOFTWARE. YOU USE THE SERVICE AT YOUR SOLE RISK.
Some jurisdictions do not allow the exclusion of certain warranties. In those jurisdictions, the above exclusions apply to the fullest extent they lawfully can, and any implied warranty that cannot be excluded is limited to thirty (30) days from first download or the minimum period the law requires, whichever is shorter.
19. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NETFORGE AND ITS OWNERS, OFFICERS, EMPLOYEES, CONTRACTORS, LICENSORS, AND PARTNERS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, LOST GOODWILL, REPLACEMENT COSTS, COST OF COVER, BUSINESS INTERRUPTION, SYSTEM DAMAGE, MISSED DETECTIONS, FALSE POSITIVES, FAILED OR DELAYED EMAILS, UNAUTHORIZED ACCESS TO A DEVICE, OR HARM CAUSED BY A SCAMMER, SOCIAL ENGINEER, OR OTHER THIRD PARTY, EVEN IF ADVISED OF THE POSSIBILITY, AND WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY.
OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO US FOR SEATS IN THE TWELVE (12) MONTHS BEFORE THE CLAIM OR (B) $39.95.
These limitations allocate risk. The price of the Service reflects that allocation. They apply even if a limited remedy fails of its essential purpose. They do not limit liability that the law of a non-waivable statute says we cannot limit (for example, liability for our own fraud or willful misconduct where that bar cannot be waived). You agree that any scam loss, wire transfer, credential theft, or ransomware event is caused by the third-party actor and by decisions made on the Device, not by us, except to the extent a court finds we failed a duty the law does not allow us to disclaim.
20. Indemnification
You will defend, indemnify, and hold harmless NetForge and its owners, employees, and partners from and against any claim, loss, liability, damage, cost, and expense (including reasonable attorneys’ fees) arising out of or related to: (a) your use or misuse of the Service; (b) a Device you do not own or lack authority to administer; (c) Mark As Safe, Close Program, uninstall, blocking, or Lockdown decisions; (d) Family Alert messages; (e) your breach of these Terms; (f) your violation of law or third-party rights; or (g) a chargeback or payment dispute you initiate without basis. We may assume exclusive defense at your expense; you will cooperate.
21. Release as to third-party actors
You release NetForge from claims to the extent they arise from the acts or omissions of scammers, callers, remote-access operators, payment processors, email providers, Microsoft, browser vendors, or other third parties. If you are a California resident, you waive California Civil Code § 1542 (and similar laws) with respect to that release, which would otherwise preserve unknown claims. You understand you may have claims you do not now know.
22. Changes to the Service and to these Terms
We may amend these Terms by posting an updated copy on the Site and revising the “Last updated” date. Material adverse changes will be effective thirty (30) days after posting, or later if the post so states; we may also email the Account address. Continued use after the effective date is acceptance. If you do not agree, your sole remedy is to stop using the Service and, if you wish, request Seat cancellation for the unused remainder — which, except as Section 8 or law requires, does not create a refund right.
The copy under Settings → Terms of Service in the desktop app is a notice and disclaimer for the Software. If it conflicts with these Terms, these Terms control except where the in-app text is more protective of us and a court would enforce it as an additional disclaimer.
23. Suspension; termination
You may stop using the Service at any time. We may suspend or terminate access immediately if you materially breach these Terms, if payment fails, if we must do so by law, or if continued operation poses a security or legal risk. We may also discontinue the Service on reasonable notice. Upon termination, the license ends and you must uninstall the Software. Sections that by nature should survive (including 6 (restrictions), 8, 14–21, 24–32) survive.
Expiration of a Seat without renewal ends the right to run the Software on that Device under that Seat. We may, but need not, allow a grace period or read-only dashboard access.
24. Informal resolution; arbitration; class waiver
Before filing a claim, you will email support@piir.us a written description of the dispute and wait thirty (30) days while we try to resolve it. We will do the same if we have a current email for you.
Except for (i) small-claims court actions that qualify and stay in that court on an individual basis, and (ii) applications for injunctive relief to protect intellectual property or unauthorized use of the Service, any dispute arising out of or relating to these Terms or the Service shall be resolved by binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules (or, if you are using the Service primarily for a business, its Commercial Arbitration Rules). The seat of arbitration shall be in the State of Illinois, U.S.A., unless the applicable rules require a different place or a remote hearing. Judgment on the award may be entered in any court of competent jurisdiction.
YOU AND NETFORGE 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, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON’S CLAIMS OR PRESIDE OVER ANY FORM OF CLASS OR REPRESENTATIVE PROCEEDING. IF THIS CLASS WAIVER IS FOUND UNENFORCEABLE AS TO A PARTICULAR CLAIM, THAT CLAIM MUST PROCEED IN COURT, NOT ARBITRATION, AND THESE TERMS’ VENUE CLAUSE APPLIES.
You may opt out of arbitration within thirty (30) days of first accepting these Terms by emailing support@piir.us from your Account email with the subject “Arbitration opt-out” and your name. Opt-out does not affect any other provision. If the FAA is held not to apply, the arbitration law of Illinois applies to this Section.
25. Governing law; venue
These Terms are governed by the laws of the State of Illinois, U.S.A., without regard to conflict-of-laws rules, and by the Federal Arbitration Act as to Section 24. Exclusive venue for any court proceeding that these Terms allow (including to confirm an award, for injunctive relief, or if arbitration does not apply) lies in the state or federal courts located in Illinois, and you consent to personal jurisdiction there. The U.N. Convention on Contracts for the International Sale of Goods does not apply. The Uniform Computer Information Transactions Act does not apply.
26. Notices
We may notify you by posting on the Site, through the Software, or by email to the Account address. Notices to us must be sent to support@piir.us and are effective when we actually receive them. Legal process must also comply with applicable procedure; email alone is not service of process unless the law says it is.
27. Assignment
You may not assign these Terms or a Seat without our prior written consent, except to a successor that acquires substantially all of your assets and assumes these Terms, provided you are not in breach. We may assign these Terms to an affiliate or in connection with a merger, financing, or sale of assets. Any other attempted assignment is void. These Terms bind permitted successors.
28. Force majeure
We are not liable for delay or failure caused by events beyond our reasonable control, including utility or cloud failure, DDoS, labor dispute, pandemic, change in law, or failure of Square, DNS, or email providers.
29. Construction; entire agreement; severability; waiver
These Terms, the Privacy Policy, and any Order confirmation we issue are the entire agreement regarding the Service and supersede prior proposals and communications on that subject. Marketing pages, support chat, and social posts are not part of the contract unless we expressly incorporate them in writing. You represent you have not relied on any representation not set out here.
If a provision is held unenforceable, it will be modified to the minimum extent needed to make it enforceable, or severed, and the rest remains in force. A waiver must be in writing and signed (including by electronic means we authorize) to be effective, and a waiver once is not a continuing waiver. We may use subcontractors. There are no third-party beneficiaries except as Section 20 (indemnified persons) creates. You and we are independent contractors. These Terms will not be construed against the drafter.
You waive any argument that the in-app click, Site checkbox, or continued use is an unenforceable “browsewrap.” You had a reasonable opportunity to read these Terms before paying or installing.
30. Government rights
If you are a U.S. Government end user, the Software is “commercial computer software” and “commercial computer software documentation” under FAR 12.212 and DFARS 227.7202. Use, duplication, and disclosure are governed solely by these Terms.
31. Language; counterparts
The controlling language is English. Any translation is a courtesy. Electronic records and signatures satisfy writing and signature requirements.
