Terms of Service

1. The Service

Sieve is a server-side email classifier for Gmail. When you connect an inbox, the Service applies a Solicitor or Malicious label to incoming messages it determines fall into those categories, and removes the INBOXlabel (Gmail's “archive” action) on labeled messages. Messages it determines fall outside those categories are left untouched.

The classifier is fully automated. No Snowfish employee reads your mail in the ordinary course of operating the Service. See our Privacy Policy for what data we access, store, and process.

2. Eligibility

You must be at least 18 years old (or the legal age of majority in your jurisdiction) to use the Service. By using the Service, you represent that you meet this requirement and that you have the right and authority to grant the Service access to the Google account you connect.

3. Your account

You're responsible for safeguarding your account credentials and for all activity that occurs under your account. Notify us immediately at support@getsieve.io if you suspect unauthorized access.

You can disconnect your inbox at any time from the Settings page, which revokes the Service's access to Google. You can also delete your account, which purges all stored data.

4. Google account access and Limited Use

The Service requests the gmail.modify OAuth scope so it can apply labels and remove the INBOX label on messages it classifies. Our use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

We do not sell or transfer Google user data to third parties for advertising or model training, allow humans to read it (except as needed to address abuse or security incidents, or to comply with applicable law), or retain it beyond what's needed to classify messages in your inbox. Most incoming mail is handled by deterministic pre-filter rules and never leaves our backend; when a message does not match any pre-filter rule, its body text is sent to a vetted AI model provider for classification under that provider's standard API terms. Your data is not used to train the provider's models, and the provider retains classification inputs and outputs for up to 30 days for safety and abuse review before deletion.

We rely on a limited set of sub-processors to operate the Service; a current list of those that may process your data is maintained in our Privacy Policy. We maintain administrative, technical, and organizational safeguards to protect your data, and if we become aware of a security incident that compromises it, we will notify affected users without undue delay.

5. Acceptable use

You agree not to:

• Use the Service for any unlawful purpose or in violation of any applicable law, including anti-spam, privacy, and consumer protection laws.
• Reverse engineer, decompile, or attempt to extract the source code of the Service, except where applicable law expressly allows it despite this limitation.
• Use the Service to develop a competing email classification product, train any machine-learning model on our outputs, or scrape our interface.
• Connect inboxes you don't own or aren't authorized to connect.
• Submit malicious code, attempt to disrupt the Service, or interfere with other users' access.

6. Subscription and billing

The Service is a paid subscription, billed per connected Gmail inbox through our payment processor, Stripe. You choose your billing interval at signup: $20 per month or $204 per year per inbox. New subscriptions begin with a 7-day free trial; you will not be charged if you cancel before the trial ends. After the trial, your subscription renews automatically at the end of each billing period (monthly or annual, depending on the plan you chose) until you cancel.

You can cancel at any time from the billing page in your account settings. Cancellation takes effect at the end of the current billing period, and you keep access until then. Except where required by law, payments already made are non-refundable and partial periods are not prorated. If we change pricing, we will give you at least 30 days' notice by email or via the Service before the new price takes effect; you may cancel before then to decline it.

When you start a paid subscription, you authorize us and our payment processor to charge your payment method the then-current fee on a recurring monthly or annual basis, depending on the interval you chose, until you cancel. Before you are charged we present the recurring price, the billing interval, and how to cancel, and after you enroll we send a confirmation you can keep. You can cancel at any time from the billing page in your account settings, using the same online account you signed up with, without having to call or email us. Where the law requires it, we will send renewal or price-change reminders and honor any additional cancellation or refund rights you have.

7. Service availability

We aim to keep the Service available continuously but we do not guarantee uninterrupted access. We may modify, suspend, or discontinue any part of the Service at any time, with reasonable notice when feasible.

8. Intellectual property

Snowfish retains all rights, title, and interest in the Service, including its software, classifiers, design, and brand. You retain ownership of your Gmail content; you grant Snowfish a narrow, revocable license to access and process that content solely for the purpose of operating the Service for you, as described in the Privacy Policy.

9. Termination

You may terminate at any time by deleting your account. We may suspend or terminate your access if you violate these Terms, if required by law, or if we discontinue the Service. On termination, your stored data is purged in accordance with our Privacy Policy.

10. Disclaimers

The Service is provided “as is” without warranty of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. Email classification is probabilistic; we do not warrant that any specific message will or will not be classified a particular way, nor that legitimate mail will never be labeled, nor that all malicious mail will be caught.

No classifier is perfect. Malicious, phishing, or harmful messages may reach your inbox without being labeled. The Service is a supplemental filtering layer, not a complete security solution, and does not replace your own judgment when reading and acting on email. Snowfish is not responsible for any harm arising from a message that was not caught, misclassified, or classified as not malicious, regardless of the reason.

You are responsible for your own actions.If you click a link, download an attachment, reply with sensitive information, or otherwise interact with any email — whether or not the Service labeled it — you do so at your own risk. Snowfish has no liability for any loss, damage, or harm that results from your decision to engage with the contents of an email.

11. Limitation of liability

To the maximum extent permitted by law, Snowfish's total aggregate liability for any claim arising out of or relating to these Terms or the Service is limited to the greater of (a) amounts you paid us in the twelve months preceding the claim or (b) $100. In no event will Snowfish be liable for any indirect, incidental, special, consequential, or punitive damages, even if advised of the possibility.

12. Indemnification

You agree to defend and indemnify Snowfish against any claim brought by a third party arising out of your use of the Service in violation of these Terms or applicable law.

13. Changes to these Terms

We may update these Terms from time to time. Non-material changes take effect when we post them. For material changes, we will give you advance notice by email or in the Service before they take effect, and your continued use after that constitutes acceptance.

14. Dispute resolution; binding arbitration

Please read this section carefully. It affects your legal rights, including your right to bring a lawsuit in court and to participate in a class action.

Informal resolution first. Before starting any formal proceeding, you agree to email support@getsieve.io with a description of the dispute and the relief you seek, and to give us 30 days to try to resolve it informally.

Binding arbitration. If we cannot resolve a dispute informally, you and Snowfish agree that 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 Consumer Arbitration Rules, rather than in court, except as stated below. The arbitration is held before a single arbitrator, may be conducted by phone, online, or in writing, and (if an in-person hearing is required) takes place in Delaware or another mutually agreed location. The arbitrator decides all issues, except that a court may decide whether the class-action waiver below is enforceable. Judgment on the award may be entered in any court of competent jurisdiction.

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

Exceptions. Either party may bring an individual claim in small-claims court, and either party may seek injunctive or other equitable relief in court to protect its intellectual property or to stop unauthorized access to the Service. Disputes about the validity or infringement of intellectual property are not subject to arbitration.

30-day opt-out. You may opt out of this arbitration agreement within 30 days of first accepting these Terms by emailing support@getsieve.io with your account email and a clear statement that you opt out of arbitration. Opting out does not affect any other part of these Terms.

Time limit. To the extent permitted by law, any dispute relating to the Service must be filed within one (1) year after it arises, or it is permanently barred.

15. Governing law

These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-law principles. Except for disputes subject to arbitration under Section 14, you and Snowfish consent to the exclusive jurisdiction and venue of the state and federal courts located in Delaware.

16. California users

If you are a California resident and a complaint is not resolved to your satisfaction, you may contact the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by phone at (800) 952-5210.

17. General provisions

Entire agreement. These Terms, together with our Privacy Policy and any applicable order forms or supplemental terms, are the entire agreement between you and Snowfish regarding the Service and supersede all prior agreements and understandings on the same subject.

Version control.These Terms supersede any prior version as of the “Last updated” date above. If an older version is displayed elsewhere, the version linked from the Service sign-up, checkout, or account interface governs unless a later version is expressly posted as operative.

Severability. If any provision of these Terms is found invalid or unenforceable, that provision is severed and the remaining provisions continue in full force and effect.

No waiver. Our failure to exercise or enforce any right or provision of these Terms does not operate as a waiver of that right or provision.

Assignment.You may not assign or transfer these Terms or any rights or obligations under them without our prior written consent. We may assign these Terms without restriction, including in connection with a merger, acquisition, or sale of assets. These Terms bind and benefit the parties' permitted successors and assigns.

No agency. Nothing in these Terms creates an agency, partnership, joint venture, or employer-employee relationship between you and Snowfish.

Notices. We may deliver notices to you by email to your registered address, by in-service notification, or by posting on our website, effective on dispatch. Notices to us must be sent to support@getsieve.io and are effective on confirmed receipt.

Force majeure. We are not liable for any delay or failure to perform resulting from causes beyond our reasonable control, including natural disasters, governmental actions, telecommunications failures, or the acts of third-party providers.

Electronic agreements. You consent to receive communications from us electronically, and you agree that your electronic acceptance of these Terms is legally binding and has the same effect as a written signature. You waive any defense based on the electronic form of these Terms or the lack of a physical signature.

Corrections. We may correct any errors, inaccuracies, or omissions on the Service and change or update information at any time without prior notice.

Controlling language. These Terms are written in English. If any translated version conflicts with the English version, the English version controls.

Survival. Provisions that by their nature should survive termination will survive, including the intellectual property, disclaimer, limitation of liability, indemnification, dispute resolution, and general provisions sections.
