1. 100% Client-Side Processing
At DevvTools, your privacy is the most important feature and it is taken extremely seriously. All developer tools on this website operate entirely within your browser. There is no backend server that receive, process, or store the code, tokens, or strings you input into all provided tools.
Whether you are formatting sensitive JSON data, decoding JWTs, or testing Regex patterns, your data remains secure and never leaves your device.
2. Local Storage
To provide a seamless experience, your browser's local storage is used to save your input state across sessions (so if you accidentally close a tab, your work isn't lost). This data is compressed and securely stored only on your local hard drive. No one outside your browser has any access to it.
3. Google Analytics & AdSense
To keep DevvTools free, Google AdSense is used to display advertisements and Google Analytics to understand basic site traffic (like page views). These third-party services may use cookies and similar technologies to collect non-personal, aggregated data about your visit.
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to your website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings.
