1. Acceptance of Terms
These Terms of Service ("Terms") constitute a legally binding agreement between you and Clutterstrike, Inc. ("Clutterstrike," "we," "us," or "our") governing your access to and use of the Clutterstrike Agent platform, including all related websites, applications, APIs, and services (collectively, the "Service"). Please read these Terms carefully before using the Service.
By creating an account, clicking "Get started," or otherwise accessing or using the Service, you represent that you are at least 16 years of age, that you have read and understood these Terms, and that you agree to be bound by them. If you are using the Service on behalf of an organization, you represent that you have the authority to bind that organization to these Terms, and the term "you" refers to that organization.
If you do not agree to these Terms, you may not access or use the Service. We reserve the right to modify these Terms at any time; material changes will be communicated in accordance with Section 13 of our Privacy Policy.
2. Description of Service
Clutterstrike provides an AI-powered unified inbox that aggregates email (Gmail, Outlook, Office 365) together with calendar data into a single interface. The Service includes the "Clutterstrike Agent," an AI assistant capable of reading, summarizing, drafting responses to, and taking actions on communications on your behalf, subject to your explicit approval at each step.
The Service is provided on a subscription basis with different tiers offering varying levels of functionality, channel integrations, and storage. Features vary by plan and are subject to change with reasonable notice. We reserve the right to introduce new features, modify existing features, or discontinue features at our discretion. Material feature removals from paid plans will be communicated at least 30 days in advance.
The Service is provided "as is" and we do not guarantee uninterrupted availability. We target 99.5% monthly uptime for paid plans and will publish a status page at status.clutterstrike.com. Scheduled maintenance will be communicated via email and the status page.
Cluttersignal trust intelligence. The Service includes "Cluttersignal," Clutterstrike's AI-powered trust-intelligence layer, which assesses whether an email, a link, or a website shows signs of phishing, scams, impersonation, look-alike (typosquat or homoglyph) domains, or other deception, and returns a trust verdict together with the reasons behind it. Cluttersignal is available inside the unified inbox and through the Clutterstrike browser extension. The browser extension runs an automatic, on-device trust check on the pages you visit and can, when you explicitly choose to do so, check an email you are reading, a message you paste in, or a link you enter. Trust verdicts are informational only and are subject to the disclaimers in Section 7.
Signal Pro. Cluttersignal is offered both as a standalone subscription tier called "Signal Pro" and as a feature included at no additional charge in our higher workspace plans (Solo and above). On the free tier and through the extension, the core trust verdict is provided at no cost; the comprehensive Signal Pro report — which adds the written plain-English explanation, the domain-registration-age signal, and the relationship-history signal drawn from your own connected inbox — is part of the Signal Pro tier described in Section 10. Features and the contents of the report vary by plan and are subject to change with reasonable notice, as described above.
3. Account Registration & Security
To access the Service, you must create an account by providing accurate, current, and complete information. You agree to keep this information updated. You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account, whether or not authorized by you.
You must notify us immediately at security@clutterstrike.com if you become aware of any unauthorized access to your account or any other security breach. We will not be liable for any loss resulting from unauthorized use of your account credentials, provided that such use did not result from our own negligence or failure to implement reasonable security measures.
You may not share your account credentials with others, create accounts on behalf of third parties without their explicit consent, or use automated methods to create accounts. We reserve the right to suspend or terminate accounts that violate these requirements.
4. Acceptable Use
Permitted uses. You may use the Service for lawful personal, professional, and organizational communications management. You may connect your own accounts from supported third-party services, authorize the Clutterstrike Agent to process your communications, and use approved actions within the Service as intended.
Account ownership. You may only connect email, calendar, and other accounts that you personally own, that you are authorized by your employer or principal to use, or that have been formally delegated to you (for example, an Outlook shared mailbox where you are a named delegate). You represent that the account credentials and OAuth grants you supply to Clutterstrike are lawful, current, and authorized.
Prohibited conduct. You may not use the Service to: transmit, store, or process any content that is illegal under applicable law; harass, stalk, threaten, or harm any individual; distribute spam, malware, or phishing content (see Section 5 for the full anti-spam terms); circumvent or attempt to circumvent any security feature of the Service; engage in unauthorized access to third-party systems through the Service; scrape, reverse engineer, or decompile any part of the Service; resell or sublicense access to the Service without our written consent; or interfere with the integrity or performance of the Service or its underlying infrastructure.
Browser extension — analyze only. The Clutterstrike browser extension is provided for the limited purpose of checking the trust of content you encounter. It authenticates to our trust API using a least-privilege, trust-scoped access token that authorizes trust analysis only and nothing else; it does not grant the extension the ability to send mail, change your account, or act on your behalf. You may use the extension only to assess email, links, and websites you are lawfully viewing or that you supply. You may not use the extension, or the trust API behind it, to: scrape, harvest, or bulk-collect content or domains; submit content you have no lawful right to process; drive automated, scripted, or high-volume requests, circumvent rate limits, or otherwise use the trust API as a general-purpose reputation, enrichment, or crawling service; or reverse engineer, repackage, or resell the trust verdicts. We may rate-limit, suspend, or revoke extension access that we reasonably believe is being used in any of these ways.
We reserve the right to investigate suspected violations of this policy and to suspend or terminate accounts and take appropriate legal action. We may report violations to law enforcement where we believe a crime has been committed.
5. Email Sending and Anti-Spam Compliance
You are the sender. When you use the Service to send email through your connected Gmail, Outlook, or Microsoft 365 account, you — not Clutterstrike — are the legal sender of that email for purposes of the U.S. CAN-SPAM Act (15 U.S.C. §7701 et seq.), Canada's Anti-Spam Legislation ("CASL"), the EU ePrivacy Directive, the UK Privacy and Electronic Communications Regulations ("PECR"), the EU General Data Protection Regulation ("GDPR") with respect to marketing communications, and any other anti-spam law applicable to you or your recipients. Clutterstrike provides the user-interface and AI drafting layer; the email itself is transmitted from your account, under your identity, on your authority.
Your compliance obligations. When you send commercial or marketing email through the Service, you are responsible for: (a) maintaining accurate header information and a non-deceptive subject line; (b) identifying the message as an advertisement where required; (c) including a valid physical postal address in any commercial message; (d) providing a working, prominent unsubscribe mechanism in any commercial message and honoring opt-out requests within the timeframes required by applicable law (10 business days under CAN-SPAM); (e) obtaining the consent your jurisdiction requires before sending marketing email (express consent under CASL, opt-in or soft opt-in under PECR/ePrivacy, lawful basis under GDPR); and (f) maintaining records of consent where required. The Approval Gate (see Section 6) means that every outbound message generated by the Clutterstrike Agent pauses for your explicit review before transmission — exercise that review to confirm each message satisfies your obligations.
Prohibited sending behavior. You may not use the Service to: send unsolicited bulk email (UBE) or unsolicited commercial email (UCE) without the consent required by applicable law; send email with false, forged, or misleading header information; use harvested email addresses or address lists you did not obtain through lawful means; send to recipients who have opted out, unsubscribed, or otherwise revoked consent; use the Service to evade an existing email provider's anti-spam controls; or use the Service to engage in any conduct prohibited by the SHAFT vertical restrictions, the FTC's Telemarketing Sales Rule (where commercial email cross-promotes telemarketing), or any sectoral regime such as HIPAA, GLBA, or FERPA where the sender lacks the required basis to process recipient data.
Volume and automation. The Service is designed for human-reviewed communications, not for bulk automated outreach. Sending velocity is limited by your underlying email provider's per-account rate limits (Gmail, Outlook, and Microsoft 365 each enforce their own caps) and may be further rate-limited by Clutterstrike to protect platform integrity. Attempting to engineer the Service into a high-volume sending platform — including by routing the same content through multiple connected accounts, scripting the Approval Gate, or generating templated mass sends — is prohibited and grounds for suspension.
"Sent via Clutterstrike" footer (Free tier). If you are on the Free tier, AI-drafted replies sent through the Service include a small "Sent via Clutterstrike" attribution footer. This footer is a branding mark; it does not, on its own, satisfy the sender-identification or unsubscribe requirements of any anti-spam regime, and you remain responsible for adding the legally required disclosures (physical address, unsubscribe link, etc.) to commercial messages. The footer is removed automatically on paid tiers (Solo and above).
Indemnification. You agree to defend, indemnify, and hold harmless Clutterstrike, its officers, directors, employees, and agents from any claim, regulatory penalty, fine, or expense (including reasonable attorneys' fees) arising out of email you transmit through the Service in violation of CAN-SPAM, CASL, ePrivacy / PECR, GDPR, the TCPA (for any SMS sent through future integrations), or any other applicable anti-spam, anti-fraud, or telecommunications law. This obligation survives termination of these Terms.
Clutterstrike's own emails. Emails Clutterstrike sends to you about your account (welcome, password reset, billing receipts, security notices) are transactional and exempt from most consent-based anti-spam rules. Emails Clutterstrike sends about product launches, feature announcements, and marketing are commercial and include a working unsubscribe link, our physical address, and an opt-out mechanism honored within 10 business days. You may opt out of all non-transactional email at any time via Settings → Notifications or the unsubscribe link in any marketing message.
6. AI Agent Usage
The Clutterstrike Agent is an AI system that can read your connected communications, generate summaries, draft responses, schedule events, and perform other actions on your behalf. A fundamental design principle of the Service is the Approval Gate: the Clutterstrike Agent will not send, delete, modify, or otherwise take any consequential action without first presenting the proposed action to you for explicit review and approval.
You are solely responsible for reviewing all proposed Agent actions before approving them. By approving an action, you authorize the Service to execute that action on your behalf and you accept responsibility for any consequences arising from it. Clutterstrike is not responsible for outcomes resulting from actions you approve, including messages sent, meetings scheduled, or content deleted.
The Clutterstrike Agent uses large language models that may occasionally produce inaccurate, incomplete, or contextually inappropriate outputs. AI-generated summaries and drafts are provided as suggestions only. You should review all Agent outputs before acting on them. Clutterstrike makes no warranty regarding the accuracy, reliability, or completeness of AI-generated content.
You must not attempt to manipulate, jailbreak, or bypass the safety systems and operational boundaries of the Clutterstrike Agent, including through prompt injection techniques, adversarial inputs, or any other method designed to cause the Agent to act outside its intended scope or to circumvent the Approval Gate.
7. AI Feature Disclaimers
Cluttersignal is best-effort, not a guarantee. Cluttersignal screens inbound messages for phishing, scams, malicious links, prompt injection, and impersonation indicators. While we continuously tune the system using real-world threat patterns, no automated threat-screening system catches every threat, and Cluttersignal may occasionally miss a malicious message or flag a legitimate one. You should treat Cluttersignal as a defense-in-depth layer — not as a substitute for your own judgment, your email provider's spam controls, or organization-level security tooling.
No security warranty. Clutterstrike does not warrant that Cluttersignal, the Clutterstrike Agent, or any other AI-powered feature will detect, prevent, or alert you to every fraudulent, malicious, or unwanted communication. We make no representation that AI-generated drafts, summaries, classifications, or threat assessments are complete, accurate, or fit for any particular purpose. To the maximum extent permitted by applicable law, Clutterstrike disclaims all warranties — express, implied, or statutory — regarding the performance of any AI feature, including without limitation warranties of merchantability, fitness for a particular purpose, and non-infringement.
You remain responsible for verification. Before acting on any information surfaced by an AI feature — including following a link a message appears safe under Cluttersignal, sending an AI-drafted reply, accepting an AI-proposed calendar event, or relying on an AI summary of a thread — you should independently verify the underlying facts when the consequences of error would be material. The Approval Gate is designed to give you this opportunity; it works only if you use it.
Trust verdicts and reports are informational signals, not a guarantee of safety. Cluttersignal trust verdicts and Signal Pro reports — including any verdict, score, label, or report describing an email, link, or website as "safe," "trusted," "suspicious," "dangerous," or the equivalent — are automated, best-effort, informational signals to support your own decision-making, and they are provided strictly "AS IS" and "AS AVAILABLE." Clutterstrike undertakes no duty of care to detect, identify, or warn you of any particular threat, and "best-effort" describes the nature of an automated heuristic — not a service level, performance standard, or commitment to detect any threat. A trust verdict is not a guarantee, certification, warranty, or assurance that any message, link, domain, or website is safe, legitimate, or free of fraud, malware, or other harm, and it is not a substitute for your own judgment or your own security tooling. Threat actors adapt, and any automated system can be wrong in both directions: Cluttersignal may label something dangerous that is in fact harmless (a false alarm), and it may label something safe or trusted that is in fact harmful (a missed threat). This applies to the automatic on-device trust badge or indicator the browser extension may display for pages you visit without any request from you, as well as to any protection count, score, badge, or other indicator the Service or extension surfaces. The absence of a warning, a "safe" or "trusted" label, or a low or blank threat count is not an assurance that a message, link, or website is safe, and you must not treat it as one. Any protection, scan, or "caught" counts shown by the extension are local, approximate tallies for your information only; they do not represent that every threat was detected or that pages without a flag are safe, and you should not rely on them as a measure of your protection. You are solely responsible for deciding whether to open, click, reply to, trust, transact with, or otherwise act on anything you check or that the Service or extension evaluates automatically, and for independently verifying it when the consequences of error would be material. TO THE MAXIMUM EXTENT PERMITTED BY LAW, CLUTTERSTRIKE DISCLAIMS ALL WARRANTIES — EXPRESS, IMPLIED, OR STATUTORY — INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE — REGARDING TRUST VERDICTS AND REPORTS. To the maximum extent permitted by applicable law, and except for liability that cannot be excluded or limited by law (such as liability for gross negligence, willful misconduct, or fraud), any liability for any action you take or fail to take in reliance on a trust verdict or report — including reliance on a verdict that later proves to be a false "safe" or a false "dangerous" — is subject to, and does not enlarge, the limitations and exclusions of liability in Section 11 (Limitation of Liability). By using Cluttersignal or the browser extension, you acknowledge that you have read and understood this Section, that automated trust verdicts can be wrong in both directions, and that you accept the risk of relying on them; if you are unwilling to accept that risk, do not rely on the trust verdicts and do not use the feature.
Without limiting the foregoing, the limitations, exclusions, and liability cap in Section 11 (Limitation of Liability) govern and apply in full to all AI features, including Cluttersignal trust verdicts and Signal Pro reports.
8. Intellectual Property
The Service, including all software, algorithms, user interface designs, text, graphics, logos, and documentation, is owned by Clutterstrike or its licensors and is protected by United States and international intellectual property laws. Nothing in these Terms grants you any ownership right in the Service or our intellectual property.
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal and internal business purposes during your subscription term. You may not copy, modify, distribute, sell, or lease any part of the Service without our prior written consent.
You retain all rights to your data and content. By using the Service, you grant Clutterstrike a limited license to process your data as necessary to provide the Service, as described in our Privacy Policy. You represent that you have the rights necessary to grant this license for any third-party content you process through the Service.
Third-party trademarks and open-source software. Cluttersignal, Signal Pro, and the Clutterstrike Agent are products of Clutterstrike, Inc.; "Cluttersignal by Clutterstrike" and the Clutterstrike name and logo are trademarks of Clutterstrike, Inc. Gmail and Google Calendar are trademarks of Google LLC; Outlook and Microsoft 365 are trademarks of Microsoft Corporation; Claude is a trademark of Anthropic, PBC. All other product names, logos, and brands are the property of their respective owners. We use these names solely to describe interoperability with the Service; their use does not imply any affiliation with, sponsorship by, or endorsement by those companies. The Service also incorporates third-party open-source software, including ClamAV — used for attachment malware scanning and developed by Cisco Systems, Inc. and the ClamAV team under the GNU General Public License, version 2. Such components remain governed by their own licenses, and nothing in these Terms limits any right you may have under those licenses.
9. Privacy
Your use of the Service is also governed by our Privacy Policy, located at clutterstrike.com/privacy, which is incorporated into these Terms by reference. The Privacy Policy describes how we collect, use, store, and share information about you and your communications. By agreeing to these Terms, you acknowledge that you have read and understood our Privacy Policy.
If there is any conflict between these Terms and the Privacy Policy on matters relating to data handling, the Privacy Policy governs. We will not use your private communications data for any purpose beyond what is described in the Privacy Policy and these Terms.
10. Payment, Billing, and Auto-Renewal
Subscription fees. Paid plans are billed in advance on a monthly or annual basis, as selected at signup. All fees are in USD unless otherwise specified. We use Stripe to process payments; by providing payment information, you authorize Stripe to charge your payment method on the billing schedule for your plan. Stripe's terms of service apply to all payment processing.
Signal Pro tier. Signal Pro is a standalone subscription billed at $8.00 per month in USD. Like all paid subscriptions, it auto-renews — here, every month — at the then-current price until you cancel, and you may cancel at any time as described below, with cancellation taking effect at the end of the current month. Signal Pro is offered on a monthly basis only; the in-app option to switch between monthly and annual billing applies to our annual-eligible workspace plans (Solo and above), not to Signal Pro. Signal Pro is included at no additional charge in our higher workspace plans (Solo and above); if you subscribe to one of those plans, you receive Signal Pro features as part of that plan and are not charged the separate $8.00 monthly fee. The auto-renewal, cancellation, renewal-reminder, refund, plan-change, price-change, and tax terms in this Section apply to Signal Pro on the same basis as any other paid subscription.
Automatic renewal — please read. Paid subscriptions automatically renew at the end of each billing period (monthly subscriptions renew every month; annual subscriptions renew every twelve months) at the then-current price for the same plan and the same billing interval. By starting a paid subscription, you acknowledge that your subscription has an initial and recurring payment feature and you authorize Clutterstrike (acting through Stripe) to charge your payment method on file at the start of each renewal period, without further action from you, until you cancel. The renewal charge will appear on your card or bank statement as "CLUTTERSTRIKE" or a recognizable variant.
How to cancel. You may cancel auto-renewal at any time from Settings → Billing → Cancel Subscription, by writing to billing@clutterstrike.com, or by following the cancellation link in any billing-related email we send you. Cancellation takes effect at the end of the then-current billing period; you retain access for the period you have already paid for, and we do not charge a cancellation fee.
Renewal reminders. For annual subscriptions, we will send a renewal-reminder email between 15 and 45 days before each annual renewal, in compliance with California Business & Professions Code §17602 (the California Automatic Renewal Law) and equivalent automatic-renewal statutes in other U.S. states. The reminder discloses the renewal date, the amount that will be charged, how to cancel, and where to update payment information.
Refunds. Annual subscriptions cancelled within 30 days of the original purchase date (or, for renewals, within 30 days of the renewal charge) are eligible for a pro-rated refund of the unused portion. Monthly subscriptions are not eligible for partial-period refunds; cancellation simply stops the next month's charge. If we terminate your account for cause (material breach of these Terms, fraud, abuse), no refund will be issued. Refund requests can be made via Settings → Billing or by emailing billing@clutterstrike.com.
Plan changes. Upgrades take effect immediately with pro-rated billing for the remainder of the current period. Downgrades take effect at the start of the next billing period. If your payment fails, we will retry for 7 days before suspending your account. Suspended accounts retain data for 30 days, after which the account may be deleted.
Price changes. We may change subscription fees at any time. We will give you at least 30 days' advance notice of any price increase, by email to the billing address on file and in-app, and the increase will take effect at your next renewal date. Continued use of the Service after a price change takes effect constitutes acceptance of the new pricing; if you do not accept the new price, you may cancel before the effective date for a full refund of any amount paid for service not yet delivered.
Taxes. Listed prices do not include taxes. Where required by law, Clutterstrike will collect applicable sales, use, VAT, GST, or similar transaction taxes and remit them to the appropriate authority. You are responsible for any taxes assessed on your subscription that are not collected by us.
11. Limitation of Liability
To the maximum extent permitted by applicable law, Clutterstrike and its officers, directors, employees, agents, licensors, and service providers shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including but not limited to loss of profits, data, goodwill, or other intangible losses, arising out of or related to your use of or inability to use the Service, even if we have been advised of the possibility of such damages.
In no event will Clutterstrike's total cumulative liability to you for any claims arising out of or related to these Terms or the Service exceed the greater of (a) the amounts you paid to Clutterstrike in the twelve (12) months preceding the claim or (b) one hundred dollars ($100).
The limitations in this section apply to all theories of liability, whether based in contract, tort (including negligence), strict liability, or otherwise. Some jurisdictions do not allow certain exclusions or limitations of liability, so some of the above limitations may not apply to you. In such cases, liability will be limited to the fullest extent permitted by applicable law.
12. Termination
You may terminate your account at any time through the Service interface at Settings → Legal → Delete Account, or by contacting us at legal@clutterstrike.com. Upon termination, your right to access the Service ceases immediately and your data will be deleted in accordance with our retention schedule and Privacy Policy.
We may suspend or terminate your account immediately, with or without notice, if we believe you have materially breached these Terms, including but not limited to engaging in prohibited conduct, providing false information, or failing to pay amounts owed. We may also terminate the Service in its entirety upon 90 days' written notice to all users.
Upon termination for any reason, you must cease all use of the Service. All provisions of these Terms that by their nature should survive termination will survive, including sections on intellectual property, disclaimer of warranties, limitation of liability, and governing law.
13. Governing Law
These Terms and any disputes arising out of or related to them or the Service shall be governed by and construed in accordance with the laws of the State of California, United States, without regard to its conflict of law provisions. The United Nations Convention on Contracts for the International Sale of Goods does not apply to these Terms.
Any legal action or proceeding arising under these Terms shall be brought exclusively in the federal or state courts located in San Francisco County, California, and you hereby irrevocably consent to personal jurisdiction and venue in those courts. Notwithstanding the foregoing, we reserve the right to seek injunctive or other equitable relief in any court of competent jurisdiction.
For users in the European Union, you may also have rights to bring claims before the courts of your country of residence or habitual establishment, and to lodge complaints with your local data protection authority, as applicable under GDPR.
