Privacy Policy
Last updated:
Data you enter into apps
Data entered into any app is processed entirely within your browser and is never sent to or stored on our servers.
Favorites
Favorites store only app identifiers in your browser. App inputs and results are not saved, favorites do not synchronize between devices, and clearing site data removes them.
Offline copies
So that pages you have opened also open offline, your browser keeps copies of the pages this site sent and the files they need to display. These copies contain nothing you entered into apps and no results, and nothing is sent to a server. They do show, on that device only, which pages were opened; clearing site data removes them.
Analytics
This site uses Google Analytics to improve the service. Analysis uses an anonymous identifier stored in a cookie, and no personally identifiable information is collected.
We measure aggregate query length and result count, but site-search text is not sent to analytics.
We also use measurement services from Vercel to understand traffic and improve page performance. The information sent to each service is listed under “Information sent to external services”.
Advertising
This site displays ads through Google AdSense, a third-party ad service. Ad serving begins after Google's review, and while it is enabled, cookies are used as follows.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Ads Settings. Alternatively, you can opt out of third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info.
- To learn how Google uses information from its partners' sites and apps, see How Google uses information from sites or apps that use our services.
Information sent to external services

Feedback
Feedback is submitted anonymously; we do not collect email addresses or other personal information.
Submitting feedback stores two items in your browser. One is an anonymous identifier (a randomly generated UUID), created the first time you submit and sent to our server with each submission. The server hashes it together with your IP address and records only that hash with the feedback, to recognize repeated submissions from the same sender; the identifier itself and your IP address are not included in the feedback record. The other is the time of your last submission, which is used only in your browser to prevent rapid repeated submissions and is not sent to our server. Clearing site data removes both.
