Privacy Policy

Deployment review required. The server may process request metadata in web logs for delivery, troubleshooting and security. Actual log fields and retention depend on server configuration.

Browser-side tools

JSON, encoding, text, calculator, design, image, PDF, QR and barcode tools process input in your browser. Files selected for PDF/image/QR processing are not uploaded by these tools. The QR reader reads an image you select; it does not access your camera. A generated Wi-Fi QR contains the SSID and password you enter, so anyone who scans or receives that QR may obtain those credentials.

Network diagnostics

When you explicitly run a DNS or HTTP/SSL diagnostic, the hostname or URL you enter is sent to the ZTech server for checking. DNS propagation checks query Google Public DNS and Cloudflare DNS over HTTPS. The server blocks private/reserved IP targets, applies timeouts and rate limits, but diagnostic results may be logged as operational metadata. The public IPv4/IPv6 buttons contact api.ipify.org or api6.ipify.org only after you click them.

URL shortener

When you create a short link, the destination URL is stored in server-side JSON storage for up to 30 days. Short links are public and redirect to their destination. Do not shorten private, secret or sensitive URLs.

Cookies, analytics and advertising

The theme preference may be saved in local browser storage. If analytics or advertising is added, identify providers and data practices here and implement any required consent controls.

Retention and contact

Set a defined log-retention period and keep only information needed for operational or security purposes. Verify [email protected] before publishing.
