Privacy Policy
Last Updated: January 20, 2026
1. Introduction
Welcome to WhatIsSMS.com. We value your privacy and are committed to protecting your personal data. This policy explains our practices regarding information collection when you browse our guides or use our free SMS tools.
2. Data Collection & SMS Tools
Our tools (SMS Calculator, PDU Decoder, SMPP Analyzer) are designed to work client-side. This means:
- We do not store the messages you type into our calculators.
- Data is processed locally in your browser.
- We do not have access to your PDU strings or SMPP logs.
3. Analytics & Cookies
We use minimal analytics to understand site traffic and improve our content. We may collect anonymous data such as IP addresses (anonymized), browser types, and referring pages. Cookies are used solely for essential site functionality and basic performance tracking.
4. Third-Party Links
Our guides may contain links to external sites (e.g., carrier documentation or regulatory bodies). We are not responsible for the privacy practices of these third parties.
5. Data Security
We implement appropriate technical and organizational measures to protect any information we collect. Our website is served over HTTPS with HSTS enabled, ensuring all data transmitted between your browser and our servers is encrypted. We use Cloudflare for content delivery and security, which provides additional protection against common web attacks.
6. Your Rights Under GDPR
If you are located in the European Economic Area (EEA), you have certain data protection rights under the General Data Protection Regulation (GDPR). These include the right to access, correct, or delete your personal information. Since our tools process data locally in your browser and we do not store your SMS content or personal messages, there is typically no personal data for us to provide, correct, or delete. However, if you believe we have collected any personal information about you, you may contact us to exercise these rights.
7. California Privacy Rights (CCPA)
California residents have additional rights under the California Consumer Privacy Act (CCPA). You have the right to know what personal information we collect about you, request deletion of your personal information, and opt-out of the sale of your personal information. We do not sell personal information to third parties. Our minimal data collection practices mean we typically do not have personal information to disclose or delete, but you may contact us if you have questions about your rights.
8. Children's Privacy
Our website is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can take appropriate action.
9. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will notify you of any material changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top. We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information.
