Privacy by Design

MRZCalculator.com is built to be private by default. All MRZ calculations, validations, and conversions run entirely inside your web browser using client-side JavaScript. We do not transmit, log, or store any MRZ strings, personal names, document numbers, dates of birth, or any other data you enter into our tools.

No Data Collection

We do not collect personal information. You can use the MRZ Calculator, Validator, Batch Validator, and Format Converter without creating an account or providing any identifying information. No MRZ data is ever sent to our servers.

Cookies and Local Storage

We do not use tracking cookies or third-party analytics services that collect personal data. Your browser may store minimal local preferences (such as theme or language selection) strictly in your own browser's local storage. This data never leaves your device.

Server Logs

Standard server access logs may contain anonymized request information (such as IP addresses and timestamps) solely for security monitoring and abuse prevention. These logs do not contain MRZ data or tool inputs and are not used for profiling or marketing.

Third-Party Links

Our website may contain links to external tools or partner sites. These third-party services operate under their own privacy policies. We encourage you to review those policies before interacting with external services.

Data Security

Because all MRZ processing happens locally in your browser, your sensitive travel document data never travels across the internet. This architecture provides the highest level of privacy and security for MRZ handling.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date. Continued use of MRZCalculator.com after changes constitutes acceptance of the revised policy.
