Privacy Policy
Last updated: 2026-09-04
This Privacy Policy explains what happens to your data when you use 4Dev.net (the "Website"). We've tried to write it to match exactly what the Website's code actually does, not generic boilerplate.
1. Data You Submit to a Tool
When you use a converter or tool (for example, pasting JSON to convert, or entering a currency amount), that data is sent to our server only to perform the requested operation, and is not written to a database, log file, or any other persistent storage. It is discarded once the response is sent back to your browser. We do not read, retain, sell, or share the content you process through the Website's tools.
2. No Accounts or User Profiles
The Website does not offer account registration and does not build user profiles.
3. Cookies
As of the date above, 4Dev.net's own code does not set any cookies. See the Cookie Policy for full detail, including what would change if analytics or other cookie-setting features are added in the future.
4. Server Logs
Like virtually any website, the underlying hosting infrastructure may generate short-lived technical logs (such as IP address, requested URL, and timestamp) for operational purposes like debugging and abuse prevention. These are standard web server operations, not a feature built into the Website's own code, and are not used to build profiles of individual visitors.
5. Third-Party Requests
Certain tools call third-party services to function - for example, live currency/crypto rate providers, or a CDN serving a JavaScript library your browser needs. See the Third-Party Services and Advertising Disclosure page for the full list. These requests are subject to those third parties' own privacy practices, not this Policy.
6. Children's Privacy
The Website is not directed at children and does not knowingly collect personal information from children.
7. Changes to This Policy
If the Website's data practices change - for example, if analytics or advertising is introduced - this Policy will be updated accordingly, and the "Last updated" date will reflect that.
8. Contact
Questions about this Policy can be sent via the Contact and Error Reporting page.
