Frequently asked questions
Does this tool upload my data?
No. This tool runs entirely in your browser on your own device.
Where should I host app-ads.txt?
Publish it at the root of your developer website, for example: yourdomain.com/app-ads.txt
Why is app-ads.txt not getting verified?
Make sure your developer website is linked in your app store listing, the file is accessible at the root, and crawlers can reach it.
