Privacy Policy

Last updated 15 August 2026

D4N Tools has no accounts, no tracking, no analytics, and no advertising. Most tools run entirely in your browser.

Tools that run in your browser

Tools marked Your device process everything locally. What you type, paste, or upload never leaves your browser.

Tools that call external services

Tools marked 3rd-party API send only your query to the service the tool uses. D4N Tools does not store or log it. Services used:

  • Cloudflare DNS over HTTPS for DNS, SPF, DKIM, DMARC, and domain lookups.
  • RDAP registries for domain registration data.
  • IP data services (ipwho.is, ipapi.co, ipify) for the IP lookup tool.
  • Microsoft (login.microsoftonline.com, graph.microsoft.com) for Microsoft 365 tools. Sign-in happens directly between your browser and Microsoft. Access tokens stay in your browser's session storage and clear when the tab closes. D4N Tools never sees your credentials or tenant data.
  • The D4N M365 domain check API, which looks up public Microsoft records for a domain you enter and stores nothing.

Each service processes the request under its own privacy policy.

Tools that store data in D4N cloud

Tools marked D4N cloud store the minimum needed to work. Currently that is Straw Poll: the poll question, options, and vote counts are stored on Cloudflare so others can vote. Nothing is tied to your identity.

Feedback reports

The BUG and SUGGESTION buttons send a report containing only what you see before submitting: your description, optional steps, the page path and title, viewport size, coarse browser name, theme, and an optional screenshot that you can redact and must approve first. No name, email, or IP address is stored with the report.

Reports are checked by Cloudflare Turnstile to block bots, stored on Cloudflare, and deleted automatically after 90 days.

Hosting

The site is served by Cloudflare, which processes IP addresses and request metadata to deliver pages and block abuse. D4N Tools does not use this for tracking.

Cookies and local storage

Everything stored in your browser is functional and first party. You can clear it at any time via your browser's site data settings.

NameTypePurpose
d4n-themelocalStorageRemembers your dark or light mode choice. Only set if you override the system default.
d4n_favouriteslocalStoragePinned tools on the home page.
d4n_recentCookieShows your recently used tools on the home page.
*_historylocalStoragePer-tool recent search history.
d4n_voted_*CookiePrevents duplicate votes on a poll.

Cloudflare Turnstile may set its own security cookie while verifying a feedback submission. There are no tracking, analytics, or advertising cookies.

Why there is no cookie banner: UK law (PECR) requires consent only for storage that is not strictly necessary for a service you asked for. Every item above exists solely to make a feature you used work, and Turnstile is security, so no consent banner is required.
