GigaJSON (the website, its tools and the browser extension) is built so that your data stays on your computer.
What we collect
Your documents are never sent anywhere: what you open, edit or convert, and your settings, stay in your browser. There are no accounts and no ads.
To see how GigaJSON is used and to fix what breaks, it sends usage statistics and error reports to Google Analytics:
- pages visited and features used, for example "opened a JSON file of 10–50 MB", "switched to the Table view", "exported CSV" or "ran a jq query";
- errors: the kind of error and where in GigaJSON's code it happened, with any quoted text removed;
- what Google Analytics records with every visit: an anonymous identifier kept in a cookie, your browser, device type and approximate location (from your IP address, which Google Analytics doesn't store).
They never include a document's contents, its keys or values, file names, queries you write, or the addresses of documents you open or pages you view.
In the European Economic Area, the UK and Switzerland, Google Analytics sets no cookies unless you accept them in the banner the site shows; without them it only counts visits, without telling them apart. Elsewhere they're on, and you can turn them off here:
What is stored, and where
In your browser, on your computer:
- documents you open in the GigaJSON app, and their saved versions, until you delete them;
- your settings, such as the theme and code colours;
- Google Analytics cookies (
_ga,_ga_…): an anonymous identifier, so visits can be counted.
The free tools keep nothing: what you paste or open there is gone when you leave the page. Clearing the site's data in your browser deletes everything above.
Network requests
- Your browser loads the site's files from the server that hosts it. Like any web server, it may keep standard access logs (IP address, time, page requested).
- Fonts are loaded from Google Fonts, which receives your IP address as part of that request.
- Usage statistics and error reports go to Google Analytics, as described above. Google's own use of that data is covered by How Google uses information from sites that use its services.
- When you open a document from a URL, your browser downloads it directly from that address.
- Images, video and audio that a document links to are loaded only when you click "Load", unless you turn on automatic loading in Preferences.
The browser extension
The extension checks each page's content type; for JSON (and XML, if you turn that on) it reads the page's text to show it in its viewer, in your browser. The pages you view and their contents are never sent anywhere. When you're online, the extension sends the same kind of usage statistics and error reports as the site (for example "opened a 1–10 MB response in the viewer"), with an anonymous identifier kept in the extension. It never sends page addresses or their data. In Chrome you can turn this off in the extension's options ("Share anonymous usage statistics"); in Firefox it's off unless you allow it. Otherwise it makes no network requests of its own, except downloading a link you ask it to open, and it never loads media from other sites.
Changes
If this policy changes (for example, if the site starts showing ads), the new version will be posted here with a new date before the change takes effect.
