Privacy Policy

Browser processing

Each utility labels its processing mode above its controls. Browser tools, including JWT Decoder, JSON Formatter, unit converters and basic calculators, process entered content on your device. JWT Decoder does not send tokens to a token service.

Server processing

Tools labeled Controlled server processing send their inputs to this server. This includes image and file utilities, checksums, password hashing, encryption, certificate inspection and JWT Signature Checker. Enter secrets only if you trust the server and its HTTPS connection. Private submitted content is not intentionally logged or retained by the application. Image and file uploads are processed from request temporary files. Images and their generated results are not stored in the application database. PHP removes upload temporary files at the end of the request. Network diagnostics send the entered public target to the relevant DNS resolver, RDAP service or destination website. Those services may have their own logs and privacy policies.

Usage, cookies and logs

Usage records store a tool identifier, date and aggregate counts, without submitted text. Essential session and CSRF cookies support administration and forms. Rate limits use the request IP address in cache. Hosting infrastructure may keep access and error logs; administrators must configure limited retention and avoid request-body logging. No advertising or analytics scripts are enabled by default.

Contact messages

The contact form stores your name, email and message for administrators to review. Do not include passwords, tokens or other secrets. Use the contact form to request deletion of a message. Operational retention is configured by the site operator.

Changes

Review this page before submitting sensitive data. The operator must update this policy when enabling additional services or changing retention practices.
