Privacy Policy

Files and text you put into a tool

Most tools process data entirely in your browser. Those files and strings are not transmitted to us and are not stored anywhere. Closing the tab discards them.

A small number of tools require a server. Each of those pages states the fact before you submit anything, and names what is sent. We do not keep a copy after the response is returned.

What we do collect

• Standard server logs — IP address, user agent, requested URL, timestamp, response status. Retained by our hosting provider for security and abuse prevention.
• Local preferences — theme and language are stored in your browser'slocalStorage. They never leave your device.
• Anonymous usage counters — which tools are opened, so we know where to spend effort. No user identifiers, no per-visitor history.

There is no account system, so we hold no names, email addresses or passwords.

Advertising

This site is supported by Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising inGoogle Ads Settings, or manage cookies in your browser.

Third-party vendors, including Google, use the DoubleClick cookie to serve ads based on a user's visits. Ads served to users in the EEA, UK and Switzerland are subject to Google's consent framework.

Third parties

Content delivery and edge functions are provided by Cloudflare. Analytics, where used, is aggregate rather than per-user. We do not sell data, and we do not share it with advertisers beyond what ad serving itself entails.

Children

The site is not directed at children under 13 and we do not knowingly collect data from them.

Your rights

Because we do not maintain user accounts or profiles, there is generally no personal data to access, correct or delete. If you believe we hold something about you, write to[email protected] and we will respond within 30 days.

Material changes to this policy will be reflected in the date at the top of this page.
