Yes, I think i would want this one to just be a downloadable app from a website for the user to connect with their Tumblr account.
The objective would be to find all text with curse words in the users blog posts and remove them. And eventually that would include any alt-text in pictures as well. I will provide relevant artwork for the landing page.
I'd like for the app to be accessed through a website. The user would login into the website, connect to their Tumblr account to allow access, and then they can use the program to remove curse words from their blog.
Tumblr Apps normally work in the way that, they are programs that you can connect to through a webpage, login, and then login to your tumblr account to allow the App access to your account. So I think the three basic pieces that we'll need are going to be 1) the landing page 2) a paymentpage and 3) the user page that will allow the users, once logged in to their account, to mass edit their posts and search for and remove curse words for all of their posts.
I want to discuss this project with you further, let me know the best suitable time for you to schedule the meeting, Feel free to message me at any time, i used to be online 14 hrs in a day on this website so probably you will get a quick response from my end.
