Terms of Service

Effective Date: September 17, 2026 · Version 2026.09.17

1. Acceptance of Terms

These Terms of Service ("Terms") are a binding agreement between you and TaxMint, Inc., a Delaware corporation ("TaxMint," "we," "us," or "our"). TaxMint operates the website located at yearwise.ai, together with any related mobile or desktop applications and associated tools (collectively, the "Service"). By accessing or using the Service, you agree to these Terms. If you are using the Service on behalf of a business or entity, you represent that you have the authority to bind that entity, and "you" refers to that entity.

2. Description of Service

TaxMint provides informational tax modeling and educational tools. The Service is a platform for data visualization and hypothetical scenario modeling; it is not a financial filing system. TaxMint does not currently support electronic filing of tax returns.

3. Important Tax & Legal Disclaimer

TAXMINT IS NOT A REGISTERED TAX PREPARER, CPA, OR LEGAL ADVISOR.

  • Estimates only: All results are mathematical hypotheses based on user-provided data and current tax logic.
  • No professional relationship: Use of the Service does not create a fiduciary, advisory, or professional-client relationship.
  • User responsibility: You are solely responsible for the accuracy of data entered. You should verify all results with a qualified tax professional before filing any returns.

The full Tax & Legal Disclaimer, the Privacy Policy, and the Electronic Communications Consent & E-Sign Disclosure, each as published at yearwise.ai and as amended from time to time, are incorporated into and form part of these Terms (together with these Terms, the "Agreement"). The bullets above are a summary only; the full Tax & Legal Disclaimer controls as to its subject matter, subject to Section 15 below.

4. User Accounts & Security

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Because the Service handles sensitive financial data, Multi-Factor Authentication (MFA) is required for all accounts.

5. Beta and Preview Access

From time to time we may offer the Service, or features within it, on a closed beta, preview, or early access basis. During any such period, access may be limited to invited users, the Service may be provided without charge, and features may be added, changed, or removed. We will give notice before any charge begins, and no charge will be made without the consent required by Section 6. Beta and preview features may be less reliable than generally available features.

6. Subscription and Payment

Where the Service is provided without charge, this Section applies only once paid subscriptions are made available to you.

Payments are handled by Stripe. We reserve the right to change subscription pricing upon 30 days' notice.

You may cancel your subscription at any time from your billing settings. When you cancel via the Stripe Customer Portal, you retain access through the end of your current paid period; we do not provide refunds for the unused portion. If you instead choose to permanently delete your entire account workspace (via Profile → Delete Account), your subscription is cancelled immediately, all active tax profiles are un-recoverably crypto-shredded, and all local billing invoice records linked to your user identity are instantly and permanently deleted from our active database systems.

6.1 Free Trial

New subscribers receive a 7-day free trial. The trial automatically converts to a paid subscription unless cancelled before the trial ends. You will receive a reminder email three days before your trial ends with a one-click cancellation link, and you can cancel at any time from your billing settings.

Once you are charged, your bank statement will show a TaxMint descriptor with a brief "trial converted" note for the first paid cycle.

7. Account Termination & Data Deletion

You may delete your account at any time from your profile settings. Account deletion is irreversible. The deletion path:

  • Removes your data from live systems immediately.
  • Cancels any active subscription immediately (no refund for the remainder of the paid period — use the cancellation flow in §6 if you want to retain access through the end of the period).
  • Deletes billing records linked to your account in our systems. Stripe retains its own payment records.
  • Crypto-shreds all encryption keys associated with your account. Backups taken before deletion are overwritten on the rolling cycle described in Privacy Policy §6.3.

Audit-log entries (see Privacy Policy §6.4) survive deletion as the legal record of access events; they are PII-free by design.

Deletion does not prevent data from being temporarily re-created during backup restore testing in an isolated environment that is destroyed at the end of the test, as described in Privacy Policy §6.1.

8. AI-Powered Features & Third-Party Processors

The Service uses AI for the OBBBA tax auditor and related verification flows.

  • Runtime AI: Google Gemini via Google Vertex AI in our dedicated Google Cloud project. Personally Identifying Information is removed from prompts before transmission (see Privacy Policy §4). No data is used to train public models.
  • No guarantee of accuracy: AI-generated content may be incomplete, inaccurate, or "hallucinated." All AI outputs must be treated as suggestions for further investigation, not as factual tax determinations.
  • Conditional debug access (Anthropic Claude): When you submit a bug report and grant data access via the "Allow support team to access my data" checkbox, our engineering team may use Anthropic's Claude (via Anthropic's commercial API) to assist with debugging. This is governed by the break-glass consent flow described in Privacy Policy §11 and is not part of the runtime audit pipeline.
  • Third-party services: The Service relies on the following third-party processors: Supabase (authentication only), Google Cloud Platform (hosting, storage, KMS, Cloud Scheduler, audit logging), Google OAuth and, where available, Apple Sign-In (sign-in), Google Vertex AI / Gemini (runtime AI audit), Anthropic Claude (conditional debug-only — see Privacy Policy §4.1 + §11), Stripe (payments), Resend (transactional email), Yahoo Finance (market data, on-demand ticker requests only), PostHog (product analytics — only if you opt in; pseudonymous, no PII), and Sentry (PII-scrubbed application error tracking from web, mobile, and backend). A detailed breakdown is in the Privacy Policy, Section 8.

9. Data Export & Portability

The Service provides a one-click data export from your profile page. You may export all data you have entered at any time. See the Privacy Policy for details.

10. Intellectual Property

You retain ownership of the data you enter into the Service. All content, features, functionality, code, and the specific logic used to anonymize and process tax data via AI are owned by TaxMint and are protected by copyright, trademark, and other intellectual property laws.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

  • Accuracy: We are not liable for any errors in tax calculations, whether caused by software bugs or AI inaccuracies.
  • Penalties: TaxMint shall not be liable for any IRS or state tax penalties, interest, or audits resulting from your use of or reliance on the Service.
  • Data loss: We are not liable for any loss of data or financial records resulting from service interruptions, system failures, or account deletions initiated by the user.
  • Cap: Our total aggregate liability for all claims arising out of or relating to these Terms or the Service shall not exceed the amount you paid us in the twelve (12) months preceding the claim.

12. No Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. TAXMINT DISCLAIMS ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT, AND DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ANY OUTPUT WILL BE ACCURATE OR COMPLETE.

13. Indemnification

You agree to indemnify, defend, and hold harmless TaxMint and its officers, directors, employees, agents, contractors, and affiliates (collectively, the "Indemnified Parties") from and against any and all claims, demands, actions, proceedings, damages, losses, liabilities, penalties, interest, judgments, settlements, costs, and expenses (including reasonable attorneys' fees and costs of defense) arising out of or relating to:

(a) your use of or access to the Service; (b) your breach or alleged breach of the Agreement, including any representation or warranty made by you; (c) the accuracy, completeness, or lawfulness of any data, information, or documents you submit to the Service; (d) your reliance on any output, calculation, estimate, or AI-generated content from the Service in connection with any tax return, filing, election, payment, or other financial or legal decision; (e) any claim, assessment, penalty, or interest asserted by the Internal Revenue Service or any state or local taxing authority against you or any third party in connection with your use of the Service; (f) your violation of any applicable law or regulation, or of the rights of any third party, including any privacy, publicity, or intellectual property right; and (g) your use of the Service on behalf of, or your submission of data belonging to, any other individual or entity, including any spouse, dependent, client, or business, without such person's authorization.

This Section survives termination of the Agreement and deletion of your account.

14. Dispute Resolution & Class Action Waiver

Before initiating any formal proceeding, the parties shall attempt in good faith to resolve any disputes through informal discussions. The party raising the dispute shall send written notice to legal@yearwise.ai describing the dispute and the relief sought. The parties shall have thirty days from receipt of such notice to resolve the matter.

If the dispute is not resolved within such thirty-day period, the parties shall submit the dispute to non-binding mediation administered by the American Arbitration Association under its Consumer Arbitration Rules. The parties shall share mediation fees equally, and each party shall bear its own costs.

If mediation does not resolve the dispute within thirty days after it commences, the dispute shall be resolved by final and binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, before a single arbitrator, conducted remotely or in the county of your residence. Judgment on the award may be entered in any court of competent jurisdiction.

You and TaxMint each waive any right to participate in a class, collective, consolidated, or representative action or class-wide arbitration.

Either party may bring an individual claim in small claims court, and either party may seek injunctive relief in court to protect intellectual property or confidential information.

15. Order of Precedence

The Agreement constitutes the entire agreement between you and TaxMint regarding the Service and supersedes all prior or contemporaneous understandings on that subject. In the event of any conflict or inconsistency between these Terms and any document incorporated under Section 3, these Terms govern, except that the Privacy Policy governs as to the collection, use, and disclosure of personal information. Where a provision of an incorporated document addresses a matter these Terms do not, that provision applies and is not treated as a conflict. No provision of any incorporated document limits, waives, or supersedes Sections 11 through 14.

16. Severability

If any provision of the Agreement is held invalid, illegal, or unenforceable by a court or arbitrator of competent jurisdiction, that provision shall be modified to the minimum extent necessary to make it enforceable and to give effect to the parties' original intent, or, if it cannot be so modified, severed from the Agreement. The remaining provisions shall continue in full force and effect.

Sections 10 through 16, and any other provision that by its nature should survive, remain in effect after termination of the Agreement or deletion of your account.

17. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware.

18. Modifications

We may modify the Agreement at any time, with material changes taking effect thirty days after in-app notice, except that the initial publication, changes required by law, and changes that do not reduce your rights take effect on publication.

We may suspend or terminate your access, with or without notice, if you breach these Terms, use the Service unlawfully, attempt to circumvent security or access controls, scrape or reverse-engineer the Service, or use it to provide competing services.
