Privacy policy
Last updated: July 7, 2026
How input is handled
As a general rule, the tools on this site process your input locally in your browser. Text, dates, JSON strings, and other data you enter are not sent to or stored on the site's servers.
Major tools such as character counting, JSON formatting, URL conversion, date calculation, bill splitting, and random selection process input and display results on your device.
Even when ads or analytics are used, tool input such as text, dates, JSON, amounts, or candidate lists is not individually submitted for advertising or analytics.
If a future tool uses an external API, login, storage, file upload, or similar feature, the destination and storage behavior will be clearly stated on the relevant tool page.
On shared or public devices, input and results shown on screen may be visible to people nearby. Avoid entering passwords, secret keys, personal identification numbers, or confidential work information unless necessary.
Information collected through inquiries
If you use the form from the contact page, we may collect the email address, inquiry details, and any optional information you submit in order to reply or confirm details. This information is used only for responding to inquiries and necessary follow-up communication.
The contact form uses Google Forms. Information you submit is also sent to Google and handled under Google's policies. Please review the Google Privacy Policy for details.
Advertising
This site may use third-party advertising services such as Google AdSense. Ads served by third-party vendors or ad networks may appear on the site.
Google and other third-party vendors may use cookies to serve ads based on your prior visits to this site or other websites. Google's use of advertising cookies enables Google and its partners to serve ads based on your visits to this site and other sites.
You can disable personalized advertising through Google's ad settings. You can also visit www.aboutads.info to opt out of cookies used for personalized advertising by participating third-party vendors.
For more information on how Google uses data, see Google's policies and terms.
Ads will not be placed between a tool's input area and its result. They are only shown in locations that do not interfere with your work. Ad slots and ad links are labeled so they can be recognized as advertising.
Analytics
This site uses Google Analytics 4 to understand usage and improve the service. Google Analytics may use cookies and similar technologies to collect information such as page views, referrers, and usage environment. This information is not used to directly identify individuals.
You can use your browser's cookie settings or the Google Analytics Opt-out Browser Add-on to avoid Google Analytics measurement. For more information, please review the Google Analytics Terms of Service and How Google uses data when you use our partners' sites or apps.
Disclosure to third parties
Personal information we collect is not disclosed to third parties except when you consent, when required by law, or when external services are used as necessary to respond to inquiries or operate the site.

This policy may be updated to reflect changes in applicable law or the features of this site. Any changes will be posted on this page along with an updated date.
