Your data

Local tools process images, files and content in your browser. Favorites and history store only tool IDs on your device, never input content. TEKTools has no analytics.

Network tools send domain/IP to TUNGTEK and Google or Cloudflare when you request a lookup. Abuse counters store daily IP hashes with expiry, not query content. Infrastructure may retain operational logs under its own policies.

Current scope

DNS propagation compares two resolvers, not worldwide probes. SPF/DKIM/DMARC inspect records, not an actual email. HTTP headers are limited to four approved TUNGTEK domains. TLS certificate handshakes, WHOIS/RDAP and MXToolbox API are not provided.
