Terms of Service
Version 3.5
Last revised on: April 11th, 2026
Welcome to Leto. These terms govern your use of our service. We've tried to keep them clear and fair. The key things to know: we protect your data, you own your content, and you can delete your account anytime. For the full legal details, please read on.
The website located at helloleto.com (the "Site") is a copyrighted work belonging to Leto Technology, Inc. ("Company", "us", "our", and "we"). Certain features of the Site may be subject to additional guidelines, terms, or rules, which will be posted on the Site in connection with such features. All such additional terms, guidelines, and rules are incorporated by reference into these Terms.
THESE TERMS OF USE (THESE "TERMS") SET FORTH THE LEGALLY BINDING TERMS AND CONDITIONS THAT GOVERN YOUR USE OF THE SITE. BY ACCESSING OR USING THE SITE, YOU ARE ACCEPTING THESE TERMS (ON BEHALF OF YOURSELF OR THE ENTITY THAT YOU REPRESENT), AND YOU REPRESENT AND WARRANT THAT YOU HAVE THE RIGHT, AUTHORITY, AND CAPACITY TO ENTER INTO THESE TERMS (ON BEHALF OF YOURSELF OR THE ENTITY THAT YOU REPRESENT). YOU MAY NOT ACCESS OR USE THE SITE OR ACCEPT THE TERMS IF YOU ARE NOT AT LEAST 18 YEARS OLD. IF YOU DO NOT AGREE WITH ALL OF THE PROVISIONS OF THESE TERMS, DO NOT ACCESS AND/OR USE THE SITE.
PLEASE NOTE: Section 9.2 contains an agreement to arbitrate disputes and a class action waiver. Please read it carefully.
1. Accounts
1.1 Account Creation and Types
In order to use certain features of the Site, you must register for an account ("Account") and provide certain information about yourself as prompted by the account registration form. Account creation methods vary based on your relationship with participating organizations:
PTA‑Verified Users
If your organization's Parent‑Teacher Association (PTA) or Parent Association (PA) participates in a Leto partnership:
- You may register through your PTA's dedicated signup page (URLs like
/join/your-school-pta), which requires a valid security link distributed by your PTA. Organizations can rotate or revoke these links at any time. - Alternatively, your email may be verified against a PTA‑provided whitelist to confirm organization community membership.
- Once verified, that parent may invite additional caregivers (e.g., co‑parents, guardians, grandparents) without further PTA verification.
- Your PTA may receive aggregate, anonymized engagement metrics — never individual user data.
Dedicated signup links are intended only for members of that organization; misuse may result in removal.
Individual Users
If you register without an organizational partnership:
- Open registration is available
- You may sign up for our Premium family subscription
You represent and warrant that: (a) all registration information you submit is truthful and accurate; and (b) you will maintain the accuracy of that information. You may delete your account at any time by following instructions on the Site or contacting [email protected]. Leto may suspend or terminate your account in accordance with Section 7.
1.2 Account Responsibilities
You are responsible for maintaining the confidentiality of your Account login information and are fully responsible for all activities that occur under your Account. You agree to immediately notify Company of any unauthorized use, or suspected unauthorized use of your Account or any other breach of security. Company cannot and will not be liable for any loss or damage arising from your failure to comply with the above requirements.
1.3 Authentication Services
The Company uses Auth0 as our authentication service provider for both the Site and API access. When using our API, authentication is handled through Auth0, which may involve OAuth tokens from providers like Google. API users must comply with both our Terms and the terms of any third-party authentication providers used. When you create an Account or sign in to the Service, you may choose to authenticate using your existing Google account or other supported authentication providers through Auth0. By using these authentication options:
- You authorize us to access certain basic profile information from your chosen authentication provider (such as your email address and name)
- You remain subject to the terms and privacy policies of both Auth0 and your chosen authentication provider (e.g., Google)
- You understand that we do not store your Google or other third-party passwords
- You acknowledge that your ability to access the Service depends on the continued availability of these third-party authentication services
1.4 Family Accounts
The Service supports linked family accounts for households with multiple parents or guardians:
- Parents may link their accounts to share children's information and organization-related tasks
- Each parent maintains independent account access and control
- Shared information includes children's names, grades, and organization activities
- Either parent can manage and update shared children's information
- Family accounts can be unlinked by submitting a request to [email protected]
- In cases of separation or divorce, each parent retains independent access to their account
- We do not mediate disputes between parents regarding shared information
1.5 Data Sources and Consent
By creating an Account, you acknowledge and consent that:
- If you're a PTA‑Verified User, we may receive your email address from your PTA for one‑time verification of eligibility.
- You have the authority to provide information about your children and to invite additional caregivers to your family account.
- You consent to Leto processing organization‑related communications (e.g., events, tasks, announcements) solely for Service delivery.
- Your use of the Service constitutes agreement to these Terms, regardless of how your account was created or verified.
1.6 Email Integration
Premium users may optionally connect their Gmail inbox to enable automatic sender recognition and task extraction.
Premium features, including email inbox connection, are available to:
- Paid Premium subscribers

- You authorize Leto to follow links contained in emails from approved senders in order to fetch and process web page content (such as linked newsletters or event pages) on your behalf. This fetching is performed directly by Leto's servers. Leto is not responsible for the content, availability, or accuracy of third-party web pages.
- You authorize Leto to process PDF attachments and images contained in or attached to emails from approved senders. Images and PDFs may be sent to Leto's AI provider (Anthropic) for visual analysis to extract dates and event information.

- You can revoke this authorization at any time through your account settings
Purpose Limitation

- This feature serves only your family's Leto experience
Data Protection
- All sender information and email content is encrypted using AES-256-GCM encryption
- Email content is shared with our AI provider (Anthropic Claude) solely for task extraction, then deleted immediately after processing
- We do not share your email data with any other third parties. We access your Gmail data directly through Google's APIs as necessary to provide the service
- When you disconnect your email, we immediately stop accessing your inbox and delete your connection credentials and sync history. Organization-level sender mappings and email fingerprints are retained as described in our Privacy Policy.
Google API Compliance
If you connect a Gmail account, our use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We access only the minimum data necessary and do not use your Gmail data for advertising, market research, or any purpose unrelated to providing and improving the Leto service.
Leto accesses Gmail data directly through Google's APIs using our own Google Cloud Platform project credentials. No third-party intermediary processes or has access to your Gmail data during this integration.

- Inaccuracies in the data you provide
- Any violation of your PTA's own policies or applicable law in sharing data with Leto

5. Data Ownership and Usage Rights
5.1 Raw Data Ownership
Leto does not claim ownership over content from users' connected email inboxes. This includes emails, attachments, and metadata accessed via inbox integrations. Users may disconnect their inboxes at any time; disconnecting deletes connection credentials and sync history. Organization-level sender mappings and email fingerprints are retained as described in our Privacy Policy.
5.2 Transformed Data Ownership
Leto retains intellectual property rights over the structured format and system-generated metadata of transformed data (including tasks, events, sender mappings, and engagement metadata), not the underlying content. This applies solely when:
- (a) The original email was sent to a Leto inbox; or
- (b) The email was sent to a Leto-provided organization address via a PTA partnership.
5.3 Use of Transformed Data
Transformed data is used to provide and improve the Leto service. For PTA-supported families and Premium subscribers, task and event data may be shared across verified family accounts to support coordination (e.g., both parents seeing the same signup task). No personal content is ever shared outside the family unit.
5.4 Limitation on Private Emails
Leto does not process or retain direct one-on-one communications between families and organizations unless a user explicitly connects their inbox and the email matches an approved sender. Such content is treated as private and subject to deletion on request.
5.5 Requesting Deletion or Export
Families can request deletion or export of both raw and transformed data associated with their account at any time by contacting [email protected].
5.6 AI Processing Consent
By using email extraction features, you consent to the use of artificial intelligence (AI) to analyze email content, linked web page content, PDF attachments, and images for task and event identification. Anthropic's Claude AI performs this analysis, including visual analysis of images and documents, under a binding data processing agreement. Leto is not responsible for inaccuracies in extraction resulting from AI analysis of visual content.
5.7 Data Portability
Users may request an export of extracted task and event data and sender mappings in human-readable format (e.g., CSV or JSON). We do not retain or export raw email content after deletion.

You agree to indemnify and hold Company (and its officers, employees, and agents) harmless, including costs and attorneys' fees, from any claim or demand made by any third party due to or arising out of (a) your use of the Site, (b) your violation of these Terms, (c) your violation of applicable laws or regulations, or (d) your User Content. Company reserves the right, at your expense, to assume the exclusive defense and control of any matter for which you are required to indemnify us, and you agree to cooperate with our defense of these claims. You agree not to settle any matter without the prior written consent of Company. Company will use reasonable efforts to notify you of any such claim, action or proceeding upon becoming aware of it.

9.2 Dispute Resolution
PLEASE BE AWARE THAT THIS SECTION INCLUDES AN AGREEMENT TO ARBITRATE WHICH REQUIRES, WITH LIMITED EXCEPTIONS, THAT ALL DISPUTES BETWEEN YOU AND US SHALL BE RESOLVED BY BINDING AND FINAL ARBITRATION. THIS SECTION ALSO CONTAINS A CLASS ACTION AND JURY TRIAL WAIVER.
UNLESS YOU OPT OUT OF THE AGREEMENT TO ARBITRATE WITHIN 30 DAYS: (1) YOU WILL ONLY BE PERMITTED TO PURSUE DISPUTES OR CLAIMS AND SEEK RELIEF AGAINST US ON AN INDIVIDUAL BASIS, NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS OR REPRESENTATIVE ACTION OR PROCEEDING AND YOU WAIVE YOUR RIGHT TO PARTICIPATE IN A CLASS ACTION LAWSUIT OR CLASS-WIDE ARBITRATION; AND (2) YOU ARE WAIVING YOUR RIGHT TO PURSUE DISPUTES OR CLAIMS AND SEEK RELIEF IN A COURT OF LAW AND TO HAVE A JURY TRIAL.
Please read the following arbitration agreement in this Section (the "Arbitration Agreement") carefully. It requires you to arbitrate disputes with Company, its parent companies, subsidiaries, affiliates, successors and assigns and all of their respective officers, directors, employees, agents, and representatives (collectively, the "Company Parties") and limits the manner in which you can seek relief from the Company Parties.
(a) Applicability of Arbitration Agreement
All claims and disputes (excluding claims for injunctive or other equitable relief as set forth below) in connection with these Terms or the use of any product or service provided by Company that cannot be resolved informally or in small claims court shall be resolved by binding arbitration on an individual basis under the terms of this Arbitration Agreement. This Arbitration Agreement applies to you and Company, and to any subsidiaries, affiliates, agents, employees, predecessors in interest, successors, and assigns, as well as all authorized or unauthorized users or beneficiaries of services or goods provided under these Terms.
(b) Notice Requirement and Informal Dispute Resolution
Before either party may seek arbitration, the party must first send to the other party a written Notice of Dispute ("Notice") describing the nature and basis of the claim or dispute, and the requested relief. A Notice to Company shall be sent to: Leto Technology, Inc., 444 E 82nd St #17F, New York, NY 10028, or by email to [email protected]. After the Notice is received, you and Company may attempt to resolve the claim or dispute informally. If you and Company do not resolve the claim or dispute within thirty (30) days after the Notice is received, either party may begin an arbitration proceeding. The amount of any settlement offer made by any party may not be disclosed to the arbitrator until after the arbitrator has determined the amount of the award, if any, to which either party is entitled.
(c) Arbitration Rules
Arbitration shall be initiated through the American Arbitration Association ("AAA"), an established alternative dispute resolution provider that offers arbitration as set forth in this section. If AAA is not available to arbitrate, the parties shall agree to select an alternative ADR Provider. The rules of the ADR Provider shall govern all aspects of the arbitration, including but not limited to the method of initiating and/or demanding arbitration, except to the extent such rules are in conflict with these Terms. The AAA Consumer Arbitration Rules ("Arbitration Rules"), governing the arbitration, are available online at www.adr.org or by calling the AAA at 1-800-778-7879. The arbitration shall be conducted by a single, neutral arbitrator. Any claims or disputes where the total amount of the award sought is less than Ten Thousand U.S. Dollars (US $10,000.00) may be resolved through binding non-appearance-based arbitration, at the option of the party seeking relief. For claims or disputes where the total amount of the award sought is Ten Thousand U.S. Dollars (US $10,000.00) or more, the right to a hearing will be determined by the Arbitration Rules. Any hearing will be held in a location within 100 miles of your residence, unless you reside outside of the United States, and unless the parties agree otherwise. Any judgment on the award rendered by the arbitrator may be entered in any court of competent jurisdiction. Each party shall bear its own attorneys' fees and costs, except as otherwise provided by law.
(d) Additional Rules for Non-Appearance Based Arbitration
If non-appearance-based arbitration is elected, the arbitration shall be conducted by telephone, online, and/or based solely on written submissions; the specific manner shall be chosen by the party initiating the arbitration. The arbitration shall not involve any personal appearance by the parties or witnesses unless otherwise agreed by the parties.
(e) Authority of Arbitrator
If arbitration is initiated, the arbitrator will decide the rights and liabilities, if any, of you and Company, and the dispute will not be consolidated with any other matters or joined with any other cases or parties. The arbitrator shall have the authority to grant motions dispositive of all or part of any claim. The arbitrator shall have the authority to award monetary damages, and to grant any non-monetary remedy or relief available to an individual under applicable law, the AAA Rules, and these Terms. The arbitrator shall issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The arbitrator has the same authority to award relief on an individual basis that a judge in a court of law would have. The award of the arbitrator is final and binding upon you and Company.
(f) Waiver of Jury Trial
THE PARTIES HEREBY WAIVE THEIR CONSTITUTIONAL AND STATUTORY RIGHTS TO GO TO COURT AND HAVE A TRIAL IN FRONT OF A JUDGE OR A JURY, instead electing that all claims and disputes shall be resolved by arbitration under this Arbitration Agreement. Arbitration procedures are typically more limited, more efficient, and less costly than rules applicable in a court and are subject to very limited review by a court. In the event any litigation should arise between you and Company in any state or federal court in a suit to vacate or enforce an arbitration award or otherwise, YOU AND COMPANY WAIVE ALL RIGHTS TO A JURY TRIAL, instead electing that the dispute be resolved by a judge.
(g) Waiver of Class or Consolidated Actions
ALL CLAIMS AND DISPUTES WITHIN THE SCOPE OF THIS ARBITRATION AGREEMENT MUST BE ARBITRATED OR LITIGATED ON AN INDIVIDUAL BASIS AND NOT ON A CLASS BASIS, AND CLAIMS OF MORE THAN ONE CUSTOMER OR USER CANNOT BE ARBITRATED OR LITIGATED JOINTLY OR CONSOLIDATED WITH THOSE OF ANY OTHER CUSTOMER OR USER. If, however, this waiver of class or consolidated actions is deemed invalid or unenforceable, neither you nor Company is entitled to arbitration; instead all claims and disputes will be resolved in a court as set forth in section (k) below.
(h) Costs and Fees
Payment of all filing, administration, and arbitrator fees will be governed by the AAA Rules. If your claim for damages does not exceed $10,000, Company will pay all such fees unless the arbitrator finds that either the substance of your claim or the relief sought was frivolous or was brought for an improper purpose (as measured by the standards set forth in Federal Rule of Civil Procedure 11(b)). If you prevail in the arbitration and are awarded an amount greater than Company's last written settlement offer (if any), Company will pay you the greater of (i) the amount awarded by the arbitrator and (ii) $1,000.00.
(i) Opt-Out
You have the right to opt out of the provisions of this Arbitration Agreement by sending written notice of your decision to opt out to [email protected] with the subject line "Arbitration Opt-Out" within thirty (30) days after first becoming subject to this Arbitration Agreement. Your notice must include your name, your email address associated with your Leto account, and an unequivocal statement that you want to opt out of this Arbitration Agreement. If you opt out of this Arbitration Agreement, all other parts of these Terms will continue to apply to you. Opting out of this Arbitration Agreement has no effect on any previous, other, or future arbitration agreements that you may have with Company.
(j) Severability
If any part or parts of this Arbitration Agreement are found under the law to be invalid or unenforceable by a court of competent jurisdiction, then such specific part or parts shall be of no force and effect and shall be severed and the remainder of the Arbitration Agreement shall continue in full force and effect.
(k) Survival and Governing Law
This Arbitration Agreement will survive the termination of your relationship with Company. This Arbitration Agreement and any dispute subject to it shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflict of law provisions. To the extent that this Arbitration Agreement is for any reason held to be unenforceable, any litigation against Company (except for small-claims court actions) may be commenced only in the federal or state courts located in New York County, New York. You hereby irrevocably consent to the jurisdiction of those courts for such purposes.

The section titles in these Terms are for convenience only and have no legal or contractual effect. The word "including" means "including without limitation". If any provision of these Terms is, for any reason, held to be invalid or unenforceable, the other provisions of these Terms will be unimpaired and the invalid or unenforceable provision will be deemed modified so that it is valid and enforceable to the maximum extent permitted by law. Your relationship to Company is that of an independent contractor, and neither party is an agent or partner of the other. These Terms, and your rights and obligations herein, may not be assigned, subcontracted, delegated, or otherwise transferred by you without Company's prior written consent, and any attempted assignment, subcontract, delegation, or transfer in violation of the foregoing will be null and void. Company may freely assign these Terms. The terms and conditions set forth in these Terms shall be binding upon assignees.
