Privacy Policy
Toolstack ("we," "our," "the site") provides free, browser-based utility tools. This policy explains what happens to your data when you use them.
How our tools work
Every tool on Toolstack — including the JSON Merger — runs entirely in your web browser using client-side JavaScript. The files, text, or data you enter into a tool are processed locally on your own device and are never uploaded to our servers, stored in a database, or seen by us. Once you close or refresh the page, that data is gone.
Information we do collect
Like most websites, we may automatically collect limited technical information through standard web analytics and our hosting provider, such as:
- Pages visited and time spent on the site
- General location (country/region), inferred from IP address
- Browser type and device type
- Referring website (how you found us)
This information is aggregated and anonymous. We do not collect names, email addresses, or other personal identifiers unless you voluntarily provide them (for example, through the Contact page).
Cookies and advertising
If Toolstack displays advertising (including through Google AdSense), our advertising partners may use cookies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising by visiting Google's Ads Settings, or manage cookie preferences through your browser settings.
Third-party services
We may use third-party services for analytics, hosting, and advertising. These providers have their own privacy policies governing how they handle data.
Children's privacy
Toolstack is not directed at children under 13, and we do not knowingly collect personal information from children.
Changes to this policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
