1. About this Policy

This Acceptable Use Policy ("AUP") governs your use of Plural Browser and any related software, updates, and services. It is part of, and incorporated into, the Plural Browser Terms of Service ("Terms"). Capitalised terms not defined here have the meaning given in the Terms.

Compliance with this AUP is a condition of your licence. Your right to install and run Plural Browser depends on your continued compliance with this Policy and the Terms. If you do not agree with this Policy, do not use the product.

Plural Browser is a general-purpose privacy and account-management tool with substantial, everyday lawful uses. Like any web browser, it can also be misused. This Policy states what the product is for and sets out what it must never be used for.

2. What Plural Browser is for (permitted and intended uses)

Plural Browser is built for people and businesses that legitimately need to keep separate online identities cleanly separated. Intended uses include, without limitation:

• Managing multiple business accounts you are authorised to operate. For example, agencies and freelancers managing social, advertising, or marketplace accounts on behalf of clients who have authorised that access, and sellers or operators running more than one storefront or account where the relevant platform permits it and each is operated in good faith.
• Ad verification and brand safety. Checking how advertisements, listings, or content render for different audiences, regions, or configurations.
• Market, price, and SEO research. Observing publicly available pricing, search results, and market conditions across regions and account contexts.
• Quality assurance and cross-account testing of websites and web applications that you own or are authorised to test, for example verifying multi-user, multi-tenant, or role-based behaviour without cross-contaminating sessions.
• Web automation of tasks you are permitted to perform, on systems you own or are authorised to use, and in a manner consistent with those systems' terms and with applicable law.
• Personal privacy and compartmentalisation. Keeping your personal, work, and other online activities in separate, isolated identities to reduce tracking and cross-linking.

These are legitimate, common needs for businesses and individuals alike. Isolating identities, cookies, storage, fingerprints, and proxies is a lawful way to meet them.

Isolation does not create permission. If a platform's own rules forbid an account or activity, isolating that identity in Plural Browser does not make it allowed (see Sections 3 and 4).

3. What Plural Browser must never be used for (prohibited uses)

You may not use Plural Browser, alone or in combination with any proxy, script, or other tool, to do or attempt any of the following. This list is illustrative, not exhaustive.

Fraud and financial crime

• Fraud of any kind, including scams, deceptive schemes, and misrepresentation for gain.
• Payment or credit-card fraud, "carding", testing or cashing out stolen payment credentials, or trafficking in stolen financial data.
• Money laundering, terrorist financing, sanctions evasion, tax evasion, or other financial crime.

Deception, impersonation, and ban evasion for illicit purposes

• Creating or operating accounts to deceive or defraud others, or to impersonate a person, business, or brand you are not authorised to represent.
• Creating or using accounts to evade a lawful ban, suspension, or block for the purpose of continuing fraudulent, abusive, or otherwise illicit activity.
• Manufacturing fake engagement, reviews, votes, sign-ups, or "bot" accounts to manipulate a platform or deceive its users.

Unauthorised access and platform abuse

• Account takeover, credential stuffing, password spraying, or accessing any account or system you are not authorised to access.
• Circumventing or defeating security controls, rate limits, authentication, or anti-abuse measures, including bypassing CAPTCHAs, in order to commit or facilitate abuse.
• Scraping, harvesting, or automating access to data or services in violation of applicable law.

Harmful content and conduct

• Distributing malware, ransomware, spam, or phishing content, or operating command-and-control or other attack infrastructure.
• Child sexual abuse material (CSAM) or any content or conduct that sexualises, exploits, or endangers minors. We report such material to the appropriate authorities.
• Harassment, stalking, threats, doxxing, or targeting of any individual.
• Infringing the intellectual property rights of others, or trafficking in counterfeit or pirated goods.

Legal and jurisdictional limits

• Any use that violates applicable law or regulation, or that infringes the legal rights of others.
• Use by, or for the benefit of, any party subject to sanctions or located in an embargoed region, in violation of applicable trade-control laws.
• Any use of the product where your specific use of it is illegal in your jurisdiction.

4. Your responsibilities

• You are solely responsible for how you use Plural Browser. This includes ensuring that your multi-account usage and your use of any proxy comply with all applicable laws and with the terms, policies, and rules of every platform, website, or service you access.
• Third-party terms are your responsibility. Many websites permit multiple accounts; some restrict or prohibit them. Violating a third-party website's or platform's Terms of Service is your responsibility, may be prohibited under this Policy, and may carry consequences from that third party (including account suspension or legal action) that are outside our control.
• Authorisation: only operate accounts, access systems, and automate tasks that you own or are authorised to operate, access, or automate.
• Proxies and infrastructure: if you connect Plural Browser to proxies or other network infrastructure, you are responsible for sourcing them lawfully and using them in compliance with law and applicable terms.

5. Enforcement

We are not obligated to monitor use of Plural Browser, and we do not pre-screen what you do with it. We do, however, reserve the right, but assume no duty, to act when we become aware of suspected violations.

Where we have a good-faith belief that this Policy or the Terms have been violated, we may, at our discretion and to the extent permitted by law:

• Investigate suspected violations.
• Suspend or terminate your licence, subscription, and access without refund.
• Disable licence keys associated with the violation.
• Cooperate with law enforcement and regulators, and disclose information where legally required or where we reasonably believe it necessary to prevent harm or investigate a crime.
• Take any other action available to us under the Terms or applicable law.

We may act with or without notice, depending on the seriousness of the violation and our legal obligations. The rights above are in addition to, and do not limit, any other remedies available to us.

6. Reporting abuse

If you believe Plural Browser is being used in violation of this Policy, please report it to hello@aptstack.com. Include as much detail as you can (what happened, when, and any identifiers). We review reports we receive and act where appropriate, but we do not guarantee any particular outcome or response time.

7. Relationship to the Terms and to licensing

• This Policy is incorporated into, and governed by, the Terms of Service. In the event of a conflict specific to acceptable use, this Policy controls; the Terms otherwise govern.
• Compliance with this Policy is a condition of your licence. A breach of this Policy is a breach of the Terms and may result in suspension or termination as described in Section 5.
• One-device licensing: each Plural Browser licence key authorises use on a single device at a time. Sharing, reselling, or circumventing licence controls is a violation of the Terms and may result in the licence being disabled.

8. Changes to this Policy

We may update this Policy from time to time. When we make material changes, we will update the "Effective date" above and, where appropriate, notify subscribers. Your continued use of Plural Browser after a change takes effect constitutes acceptance of the updated Policy.
