Privacy & Cookie Policy
Last updated 18 September 2026
The short version
The files and text you put into the tools are never transmitted anywhere. They are processed by your own browser and discarded when you close the tab. This is not a policy promise that could quietly change — it is a property of how the site is built.
What we do not collect
- The contents of any file you open in a tool.
- Text, code, JSON or numbers you type or paste.
- Calculation inputs or results.
- Account details, because there are no accounts.
What is collected
Hosting logs
The site is served by Cloudflare, which records standard request logs — IP address, user agent, requested URL, timestamp — for security and abuse prevention. These are retained on Cloudflare's schedule and are not used to build a profile of you.
Cookies & Local Storage
Under the EU ePrivacy Directive, UK PECR, and GDPR, we provide complete transparency regarding every cookie and browser storage key used across the site:
| Storage Key / Cookie | Category | Provider | Purpose & Retention |
|---|---|---|---|
| uk-consent | Necessary | First-party (local) | Records your cookie choices so we do not prompt you on every page load. Stored in localStorage indefinitely. |
| theme | Necessary | First-party (local) | Stores your light or dark display mode preference. Stored in localStorage. |
| __gads, __gpi | Advertising | Google AdSense | Used for fraud detection, ad frequency capping, and ad reporting. Loaded ONLY if you accept advertising consent. |
You can inspect, modify, or completely withdraw your cookie consent at any time using our preference manager:
Advertising
Third-party advertising partners (including Adsterra) deliver ads to support the development and hosting of these tools. Advertising networks may process technical network identifiers (such as IP address, browser user-agent, and general geolocation) to deliver and measure ads.
If you decline advertising cookies in our cookie preferences, advertising scripts are paused. Every tool continues to work 100% client-side in your browser.
Your rights
Under the UK GDPR, EU GDPR and CCPA you may request access to, correction of, or deletion of personal data held about you, and may object to processing. For advertising data, requests are best directed to Google, which holds it. You can change or withdraw your cookie decision at any time using the "Manage Cookie Preferences" button above, the "Cookie Settings" link in the footer, or by clearing this site's data in your browser.
Children
The site is not directed at children under 13 and does not knowingly collect their personal data.
Changes
Material changes to this policy will be reflected in the date above. The commitment that tool inputs are never transmitted is architectural and is not expected to change.
