Overview

StackTools (https://www.stacktools.in) provides free browser-based developer tools. Tool inputs (JSON, tokens, code, etc.) are processed locally in your browser and are not uploaded to our servers for processing.

Tool data stays in your browser

Our utilities run client-side. We do not store the content you paste into tools such as the JSON formatter, JWT decoder, or JavaScript visualizer on our servers.

Cookies and advertising

We use Google AdSense to show ads and support free tools. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to your website or other websites on the Internet.

Google's use of advertising cookies enables it and its partners to serve ads based on visits to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ad Settings.

Visitor counter

We maintain an aggregate visitor counter via a lightweight API. This stores approximate visit counts, not your tool inputs or personal profile.

Vercel Analytics

We use Vercel Web Analytics for aggregate traffic metrics (such as page views and visitors). It is used to understand site usage and does not receive your tool inputs.

Local preferences

Theme preference may be stored in your browser's localStorage so the site can remember light/dark mode.
