Privacy Policy

Last updated: 19 September 2026

Welcome to Pocketool Lab (pocketool.app, referred to below as "this site"). This policy explains how this site and its tools, whether they are hosted on a subdomain at *.pocketool.app or under a path at www.pocketool.app/<tool>/, collect, use and protect your information. Please take a moment to read it. By using this site you agree to the practices described here.

1. Information we collect

Most tools on this site run entirely in your browser, and what you enter into them, such as amounts, addresses or the content of a QR code, is not uploaded to a server. The information we may collect includes:

• Usage analytics: anonymous statistics collected through Google Analytics (GA4), such as pages visited, time on page, device and browser type and approximate region, used to understand how the site is used and to improve it.
• Cookies and similar technologies: used for traffic analysis and for serving ads, as described below.
• Additional information in individual tools: some tools that require a sign in, such as services related to English speaking practice, may obtain your email address through a third party login such as Google sign in, and may store your learning progress. Those tools explain this separately on their own pages.

2. Use of cookies

A cookie is a small text file a website stores in your browser. This site uses cookies to analyse traffic, to remember your preferences such as dark or light mode, and through third party ad providers to serve ads. You can manage or delete cookies in your browser settings, though disabling some cookies may affect how the site works.

3. Google AdSense and third party advertising

This site uses third party advertising services including Google AdSense to serve ads. Regarding third party ad providers, please note:

• Third party vendors, including Google, use cookies to serve ads based on your prior visits to this site or to other websites.
• Google uses advertising cookies, including cookies from domains such as DoubleClick and doubleclick.net, which enable Google and its partners to serve ads to you based on your visits to this site or other sites on the internet.
• You can opt out of personalised advertising through Google Ads Settings.
• You can also opt out of some third party vendor cookies used for personalised advertising at www.aboutads.info/choices or www.youronlinechoices.com.

For how Google uses data on its partner sites, see Google's privacy and terms.

4. Google Analytics

This site uses Google Analytics (GA4) to understand how visitors use it. Google Analytics collects anonymous usage data through cookies, and that data is not used to identify you personally. You can install the Google Analytics opt-out browser add-on to stop being counted by Google Analytics.

5. How the information is used

The information we collect is used only to:

• provide and maintain the site and the tools;
• analyse and improve the content and the experience of using the site;
• serve ads relevant to the content of this site.

We do not sell your personal data.

6. Data security

This site is served over HTTPS throughout. While we take care to protect your information, no method of transmission or storage over the internet can be guaranteed to be completely secure.

7. Children's privacy

This site is not directed at children under 13, and we do not knowingly collect personal data from children.

8. Third party links

This site links to its tools, on subdomains or under paths of this site, and to external websites. Once you leave this site, those websites have their own privacy policies, and this site is not responsible for their content or practices.

9. Changes to this policy

We may update this policy from time to time. When we do, the "last updated" date at the top of this page is revised. We suggest checking back from time to time.
