Last updated: November 26, 2025

These Terms of Service ("Terms") govern your access to and use of TinyValidator's email verification API and related services ("Service"). By using our Service, you agree to be bound by these Terms.

1. Service Description

TinyValidator provides an email verification API that checks the validity and deliverability of email addresses. Our Service performs syntax validation, domain verification, mailbox checks, and risk assessment.

2. Account Registration

To use our Service, you must create an account and obtain API credentials. You are responsible for:

  • Providing accurate account information
  • Maintaining the security of your API keys
  • All activity that occurs under your account

3. Acceptable Use

You agree to use the Service only for lawful purposes. You shall not:

  • Use the Service to send spam or unsolicited communications
  • Attempt to circumvent rate limits or usage restrictions
  • Reverse engineer, decompile, or attempt to extract source code
  • Resell or redistribute the Service without authorization
  • Use the Service to harvest or collect email addresses for malicious purposes

4. Data Handling

What We Process

When you submit an email address for verification, we process it to determine its validity. This involves checking syntax, DNS records, and where possible, mailbox existence.

What We Store

We do not permanently store the email addresses you verify. We may maintain an encrypted, temporary cache to improve response times for repeated queries. This cache is automatically purged and is not used for any purpose other than improving Service performance.

Your Responsibilities

You are responsible for ensuring you have appropriate consent or legal basis to verify the email addresses you submit to our Service.

5. API Usage and Rate Limits

Your use of the API is subject to rate limits based on your subscription plan. Exceeding these limits may result in temporary throttling or suspension of access.

6. Payment Terms

Paid plans are billed in advance on a monthly or annual basis. Refunds are provided at our discretion. We reserve the right to modify pricing with 30 days notice.

7. Service Availability

We strive to maintain high availability but do not guarantee uninterrupted access. We may perform maintenance or updates that temporarily affect Service availability.

8. Intellectual Property

The Service, including its design, features, and documentation, is owned by TinyValidator. You retain ownership of any data you submit to the Service.

9. Limitation of Liability

To the maximum extent permitted by law, TinyValidator shall not be liable for any indirect, incidental, special, consequential, or punitive damages resulting from your use of the Service.

10. Indemnification

You agree to indemnify and hold harmless TinyValidator from any claims, damages, or expenses arising from your use of the Service or violation of these Terms.

11. Termination

We may suspend or terminate your access to the Service at any time for violation of these Terms or for any other reason at our discretion. You may terminate your account at any time.

12. Changes to Terms

We may modify these Terms at any time. Continued use of the Service after changes constitutes acceptance of the modified Terms.

13. Governing Law

These Terms are governed by the laws of the jurisdiction in which TinyValidator operates, without regard to conflict of law principles.
