Contact YYDevTools
Have a question, spotted a bug, or want to suggest a tool? There are no accounts and no support tickets here — just email, and the code is public. Here is how to reach the person who builds and runs this site.
For anything at all — questions about a tool, a privacy request, a partnership, or feedback — write to yeshanyesh12@gmail.com. Emails are read personally and usually answered within a few days.
Report a bug or request a tool
YYDevTools is open source. The fastest way to report a bug or ask for a new tool is to open an issue on GitHub, where you can see what is already planned and add your own idea:
Open an issue on GitHub · browse the source code.
Privacy and data requests
The site has no accounts and does not build a profile of you, so there is normally no personal data to export or delete. If you still have a privacy question, email the address above or read the full Privacy Policy.
What to expect
This is an independent project maintained by one developer, not a company with a support desk. Please be patient and include as much detail as you can — the tool you were using, your browser, and what you expected to happen. That context is what makes a report actually fixable.
