Xiaogouzizhangdang-dpulunie3bo4.edgeone.dev presents itself as a daily expense tracker called '小狗结余日记' (Little Dog Balance Diary). It accepts Apple Pay, which suggests it's a commercial service rather than a casual hobby project. But that's where the professionalism ends.
Most legitimate budgeting apps have clear contact information, a privacy policy explaining how they handle your financial data, and some kind of about page. This site has none of those. The content is hidden behind JavaScript, so even basic details about the company are inaccessible. The domain is also very new with no history on the Wayback Machine.
If you're asking 'is xiaogouzizhangdang-dpulunie3bo4.edgeone.dev a scam', the evidence doesn't prove scam, but it does prove the site falls short of what should be expected. Without knowing who runs it or how your data is handled, the safest move is to avoid entering any personal or payment details here. There are plenty of well-established budgeting apps that offer transparency from the start.
