Terms of Service

Last updated: September 22, 2026

These Terms of Service (these "Terms") form a binding agreement between Sareli Labs S.A.S., a company organized under the laws of Mexico with registered address at Zapopan, Jalisco, Mexico ("TrueLead," "we," "us," or "our"), and the person or entity that registers for or uses the Service ("Customer," "you," or "your").

By creating an account, clicking "I agree," or accessing or using the Service, you accept these Terms. If you do not agree, do not use the Service.

1. Definitions

2. Acceptance; Eligibility; Authority

2.1. You must be at least 18 years old (or the age of legal majority in your jurisdiction, if higher) to use the Service.

2.2. If you register or use the Service on behalf of a company or other entity, you represent and warrant that you have the authority to bind that entity to these Terms, and "Customer" refers to that entity.

2.3. These Terms, together with the AUP, the Privacy Policy, the Cookie Policy, the DPA (where applicable), the Refund and Cancellation Policy, and any order form or Plan selection you accept, constitute the entire agreement between you and us regarding the Service.

3. Account Registration and Security

3.1. To use the Service you must create an account using a valid email address and password. We do not require your name or company name at signup. You must keep your registration email address accurate and current.

3.2. You are responsible for maintaining the confidentiality of your account credentials, including your password and API Keys. API Keys are credentials: anyone holding your API Key can use the Service as you, and all activity under your account or API Key is your responsibility.

3.3. You must not share API Keys publicly, embed them in client-side code or public repositories, or permit unauthorized persons to use them. You must promptly revoke and rotate any compromised credential and notify us at hola@trueleadapp.com of any unauthorized access or security incident affecting your account.

3.4. We may suspend or terminate accounts created with false information, disposable credentials used to abuse the free trial, or accounts that we reasonably believe pose a security risk.

4. Description of the Service

4.1. The Service validates email addresses and phone numbers that you submit. Features include syntax validation, domain and MX-record checks, disposable-email detection, mailbox verification, bulk CSV upload validation, phone validation (including carrier detection, line-type identification, and international formatting), and access via a REST API authenticated by API Keys. Available features depend on your Plan.

4.2. TrueLead is a validation service, not a lead-generation, lead-finding, or data-scraping service. We do not sell, rent, or provide contact lists. You submit your own data; we return Validation Results for that data only.

4.3. Free Trial. New accounts receive a 14-day free trial including 500 free validations. No credit card is required to start the trial. At the end of the trial, access to paid features ends unless you subscribe to a paid Plan. We may limit or deny free trials where we detect abuse (e.g., multiple accounts created to stack trial quotas).

4.4. Fair Use. Each Plan includes a quota of validations per billing cycle. You must use the Service within your Plan's quota and rate limits and in accordance with the AUP. Automated, excessive, or abusive usage that degrades the Service for others is prohibited even within quota.

4.5. We may modify, update, or discontinue features of the Service with reasonable notice where the change materially reduces functionality. We are not obligated to maintain backward compatibility of beta or experimental features.

5. Subscriptions, Billing, and Payment

5.1. Plans and Pricing. Paid Plans are offered as monthly subscriptions priced from USD $29 to USD $449 per month across nine plans in the Bundle, Email-only, and Phone-only families. Prices are displayed in US dollars for reference but are billed in Mexican pesos (MXN) at the MXN price shown at checkout. USD figures are approximate equivalents and may vary with exchange rates.

5.2. Payment Processor. Payments are processed by Stripe, Inc. By subscribing, you agree to Stripe's terms and authorize us (via Stripe) to charge your payment method. We do not store your full payment card details. Subscription management — including plan changes, cancellation, and invoice retrieval — is available self-serve through the Stripe Customer Portal linked from your account.

5.3. Auto-Renewal. Paid Plans renew automatically each month unless cancelled before the renewal date through the Stripe Customer Portal. Cancellation takes effect at the end of the then-current billing period; you retain access until that date.

5.4. Overage Fees. If your usage exceeds your Plan's included quota, per-unit overage fees apply at the rates shown on the pricing page or your order form, and will be charged with your next invoice. You are responsible for monitoring your usage via the dashboard.

5.5. Plan Changes. Upgrades take effect promptly and may be prorated; downgrades and cancellations take effect at the start of the next billing cycle, as implemented through the Stripe Customer Portal.

5.6. Taxes. Prices are exclusive of applicable taxes unless stated otherwise. Where required by law, Mexican value-added tax (IVA) or other applicable taxes will be added to your invoice. You are responsible for all taxes associated with your purchase, excluding taxes on our net income.

5.7. No Refunds. Except as expressly stated in our Refund and Cancellation Policy (trueleadapp.com/refund) or required by applicable law, fees are non-refundable, including for partial billing periods and unused quota.

5.8. Failed Payments. If a payment fails, we may retry the charge, suspend access to paid features, and/or terminate your Plan after notice. Unpaid amounts remain due.

6. Submitted Data; Customer Warranties and Responsibilities

6.1. Roles of the Parties. As between you and us, you are the data controller of any personal data contained in Submitted Data, and TrueLead acts solely as a data processor (or service provider) processing Submitted Data on your behalf and on your documented instructions, as set out in the DPA (trueleadapp.com/dpa), which is incorporated into these Terms.

6.2. Your Warranties. You represent, warrant, and covenant that:

(a) you have a lawful basis (including valid consent where required) under all applicable data-protection and privacy laws to submit each email address and phone number in the Submitted Data to us for validation;

(b) the Submitted Data was collected lawfully and not in violation of any law, contract, or third-party right, including laws prohibiting scraping or harvesting of contact data;

(c) you will not submit personal data of residents of the European Economic Area, the United Kingdom, or Switzerland unless you have a valid lawful basis under the GDPR/UK GDPR for both your submission and our processing on your behalf;

(d) you will provide any notices to, and obtain any consents from, the individuals whose data you submit, to the extent required by law;

(e) you will not submit special-category (sensitive) personal data, personal data of children, passwords, or credentials, as further described in the AUP; and

(f) your use of the Service and Validation Results will comply with all applicable laws, including anti-spam, direct-marketing, and telemarketing laws.

6.3. Anti-Spam Prohibition. You must not use the Service or Validation Results to build, clean, or enrich lists for sending unsolicited bulk messages in violation of applicable law, including the U.S. CAN-SPAM Act, Mexico's Federal Law on the Protection of Personal Data Held by Private Parties (LFPDPPP), the EU/UK GDPR and ePrivacy rules, and applicable telemarketing laws for phone data. Validation does not make an unlawful list lawful.

6.4. License to Process. You grant us a limited, non-exclusive, worldwide, royalty-free license to host, copy, transmit, and process Submitted Data solely to provide the Service to you, to return Validation Results, and as otherwise permitted by the DPA and Privacy Policy. We acquire no ownership of Submitted Data.

6.5. We may, but are not obligated to, screen or refuse to process Submitted Data that we reasonably believe violates these Terms or the AUP.

7. Acceptable Use

Your use of the Service is subject to the Acceptable Use Policy, which covers prohibited uses, prohibited data, API usage rules, anti-spam and marketing-compliance obligations, and enforcement. A material breach of the AUP is a material breach of these Terms.

8. Intellectual Property

8.1. Our IP. We (and our licensors) own all right, title, and interest in and to the Service, the Documentation, our validation systems and algorithms, our trademarks and branding, and all improvements, modifications, and derivative works of the foregoing, excluding Submitted Data. These Terms grant you no rights except the limited right to access and use the Service during your subscription in accordance with these Terms and the Documentation.

8.2. Your Data. As between the parties, you own (or hold the necessary rights to) the Submitted Data. Subject to payment of applicable fees, you may use the Validation Results for your internal business purposes. You may not resell the Service or Validation Results as a competing validation service, as described in the AUP.

8.3. Feedback. If you provide suggestions or feedback about the Service, we may use it without restriction or compensation to you.

9. Confidentiality

9.1. Each party may receive non-public information of the other party ("Confidential Information"), including, in our case, non-public aspects of the Service, and in your case, Submitted Data. Confidential Information excludes information that is public without breach, already known, independently developed, or rightfully received from a third party without duty of confidentiality.

9.2. The receiving party will use Confidential Information only to perform under these Terms, protect it with at least reasonable care, and not disclose it to third parties except to personnel and subprocessors bound by confidentiality obligations, or as required by law (with notice where legally permitted).

9.3. Our handling of personal data in Submitted Data is additionally governed by the DPA and Privacy Policy.

10. Accuracy Disclaimer; Service Levels

10.1. Probabilistic Results. Email and phone validation is inherently probabilistic. Validation Results reflect signals available at the time of the check (e.g., syntax, domain/MX configuration, mailbox responses, carrier data) and may be inaccurate, incomplete, or become outdated immediately. We do not warrant that any email address will accept delivery, that any message will reach an inbox, that any phone number is active or assigned to a particular person, or that any Validation Result is 100% accurate. You use Validation Results at your own risk and remain responsible for your own sending, dialing, and compliance decisions.

10.2. Business Tier SLA. Certain Business-tier Plans advertise an SLA guarantee, dedicated API access, and an account manager. The specific service levels, credits, and remedies applicable to those Plans are set out in the applicable order form or a separate service level schedule, which will prevail over this Section for those Plans. Except as stated in such an SLA, we do not guarantee uninterrupted or error-free operation of the Service.

11. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, EXCEPT AS EXPRESSLY STATED IN THESE TERMS OR AN APPLICABLE SLA, THE SERVICE, DOCUMENTATION, AND VALIDATION RESULTS ARE PROVIDED "AS IS" AND "AS AVAILABLE," AND WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

12. Limitation of Liability

12.1. TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, LOST GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

12.2. TO THE MAXIMUM EXTENT PERMITTED BY LAW, EACH PARTY'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE AMOUNTS PAID OR PAYABLE BY YOU TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM (OR, IF THE CLAIM ARISES DURING THE FREE TRIAL OR BEFORE ANY PAYMENT, USD $100).

12.3. Carve-Outs. The limits in Sections 12.1 and 12.2 do not apply to: (a) your breach of Section 6 (Submitted Data; Customer Warranties) or the AUP; (b) your indemnification obligations under Section 13; (c) either party's gross negligence, willful misconduct, or fraud; or (d) liability that cannot be limited under applicable law.

12.4. Some jurisdictions do not allow certain limitations of liability, so some of the above may not apply to you; in that case our liability is limited to the greatest extent permitted.

13. Indemnification by Customer

You will defend, indemnify, and hold harmless TrueLead, its affiliates, officers, directors, employees, and agents from and against any third-party claims, demands, actions, damages, losses, liabilities, fines, penalties, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) the Submitted Data, including any claim that its collection, submission, or processing infringes or violates any law or third-party right; (b) your lack of lawful basis or consent for the data you submit; (c) your marketing, email, SMS, or telemarketing activities, whether or not they use Validation Results; (d) your breach of these Terms, the AUP, or applicable law; or (e) your misuse of API Keys or account credentials. We will promptly notify you of any indemnified claim, allow you to control the defense (subject to our right to participate with our own counsel at our expense), and reasonably cooperate. You may not settle a claim in a manner that admits fault on our part or imposes obligations on us without our prior written consent.

14. Term, Suspension, and Termination

14.1. Term. These Terms begin when you first accept them or use the Service and continue until terminated. Paid Plans continue month-to-month until cancelled as described in Section 5.

14.2. Suspension. We may suspend or restrict your access immediately, with notice where practicable, if: (a) you breach these Terms or the AUP; (b) your use poses a security risk, legal risk, or risk of harm to us, other customers, or third parties; (c) we detect fraud, abuse, or unlawful activity; or (d) payment is overdue. We will lift suspension once the issue is resolved, unless we terminate instead.

14.3. Termination. Either party may terminate these Terms if the other materially breaches them and fails to cure within 30 days of written notice (no cure period applies to breaches incapable of cure, such as AUP violations involving unlawful data or spam). You may terminate at any time by cancelling your subscription and ceasing use of the Service. We may terminate for convenience with 30 days' notice, in which case we will refund prepaid fees for the unused remainder of the current billing period.

14.4. Effect of Termination. Upon termination or expiry: (a) your right to access the Service ends; (b) accrued payment obligations remain due; (c) we will delete or anonymize Submitted Data and account data in accordance with our data retention practices described in the Privacy Policy (trueleadapp.com/privacy) and the DPA, typically within 90 days, except where retention is required by law or for legitimate business records (e.g., invoices); and (d) Sections that by their nature should survive (including 5.7, 6.4 (license ends except as needed for deletion), 8, 9, 10.1, 11, 12, 13, 14.4, 16, and 17) survive.

15. Changes to These Terms

We may update these Terms from time to time. If we make a material change, we will provide at least 30 days' advance notice by email to your registered address, by prominent notice in the dashboard, or both, and will update the "Last updated" date above. Continued use of the Service after the effective date of the changes constitutes acceptance. If you do not agree to the updated Terms, you must cancel your subscription and stop using the Service before the changes take effect.

16. Governing Law and Dispute Resolution

16.1. These Terms are governed by the laws of Mexico, without regard to conflict-of-law rules.

16.2. The parties submit to the exclusive jurisdiction of the competent courts of Zapopan, Jalisco, Mexico, waiving any other forum that may correspond to them.

16.3. Nothing in this Section prevents either party from seeking injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property or Confidential Information.

16.4. To the extent permitted by law, claims must be brought in the parties' individual capacities and not as part of any class or representative proceeding.

17. Miscellaneous

17.1. Assignment. You may not assign or transfer these Terms without our prior written consent, except to an affiliate or in connection with a merger or sale of substantially all of your assets, with notice to us. We may assign these Terms to an affiliate or in connection with a merger, reorganization, or sale of assets. Any prohibited assignment is void.

17.2. Force Majeure. Neither party is liable for delay or failure to perform caused by events beyond its reasonable control, including natural disasters, war, terrorism, labor disputes, government actions, internet or telecommunications failures, or failures of third-party providers (including AWS and Stripe), provided the affected party uses reasonable efforts to mitigate.

17.3. Severability; Waiver. If any provision is held unenforceable, it will be modified to the minimum extent necessary to be enforceable, and the remainder remains in effect. A failure to enforce a provision is not a waiver.

17.4. Entire Agreement. These Terms (including the documents they incorporate: the AUP, Privacy Policy, Cookie Policy, DPA, and Refund and Cancellation Policy) are the entire agreement between you and us regarding the Service and supersede all prior agreements and understandings. Any terms in your purchase orders or other documents are rejected and have no effect.

17.5. Notices. We may provide notices to the email address on your account or via the dashboard. Legal notices to us must be sent to hola@trueleadapp.com (with copy by mail to Zapopan, Jalisco, Mexico, if available) and are effective on receipt.

17.6. Relationship. The parties are independent contractors. Nothing in these Terms creates a partnership, agency, joint venture, or employment relationship.

17.7. Language. These Terms are executed in English. Any translation is provided for convenience only; the English version controls.
