Chrome Extension Privacy Policy
Overview
This policy applies to all Chrome browser extensions published by John McAlpin. These extensions are built as productivity tools and are designed with a strict principle: your data stays on your device. No user data is collected, stored, or transmitted to any external server.
What data the extensions access
When you trigger an extension's action (for example, clicking "Extract Markdown"), the extension reads content from the webpage you are currently viewing in order to perform its stated function in your browser. This access is:
- Temporary — content is processed in memory only for the duration of that action
- Local — all processing happens entirely within your browser
- User-initiated — extensions take no action unless you explicitly trigger them
What data is collected and stored
None. These extensions do not collect, log, store, or retain any personal information, browsing history, page content, or usage data — either locally or on any server.
Data sharing
No user data is shared with any third party. These extensions do not include analytics, advertising, crash reporting, or any other service that transmits data externally.
Permissions
Extensions request only the permissions necessary for their stated function. Each permission is documented in the Chrome Web Store listing. No permission is used for any purpose beyond what is described.
Cookies and analytics on johnmcalpin.com
This section covers this website, not the Chrome extensions above. The site uses a small number of cookies, listed below.
- cookie_consent (strictly necessary, 180 days): remembers your cookie choice so you are not asked on every page. It holds only your choice and the time you made it.
- _ga and _ga_<ID> (analytics, up to 2 years): set by Google Analytics 4, loaded through Google Tag Manager, to count visits and see which pages are useful. Google Analytics 4 does not log or store IP addresses.
- Cloudflare security cookies (strictly necessary): the site is served through Cloudflare, which may set short-lived cookies to block bots and abuse, including on the contact form.
If you are in the UK, the EU, the EEA or Switzerland, analytics cookies are only set if you accept them, and Google Tag Manager does not load until you do. The legal basis is your consent. You can change or withdraw it at any time with the Cookie Settings link at the bottom of every page; withdrawing deletes the analytics cookies.
Everywhere else, Google Analytics loads by default. You can block or delete cookies in your browser settings, or use Google's Analytics opt-out browser add-on.
Google may process analytics data in the United States. Google LLC is certified under the EU-US Data Privacy Framework and its UK Extension, which cover those transfers.
Children's privacy
These extensions do not knowingly collect data from anyone, including children under 13.
Changes to this policy
If this policy changes materially, the effective date above will be updated. Continued use of an extension after a policy update constitutes acceptance of the revised terms.
