Common questions
Money is complicated.
Your app shouldn't be.
Most finance apps are built for simple lives. Fixed salary, one bank account, no loans. Collie handles the messy reality — mortgages that change, income that varies, and bills that only come once a year.
Your finances are nobody else's business.
Built with privacy by design. Your data is stored securely in the EU, protected by row-level security, and never shared with advertisers or third parties.
Simple pricing, no surprises.
Start with the essentials. Upgrade to Pro for unlimited history and advanced features.

No data imports, no bank connections. Just open Collie and start building the plan.
