Built to show its working

The loan tool explains assumptions and exports its monthly schedule. Image tools report actual output, not only a quality slider. Limits stay beside the result.

How the tools work →

Private by design, honest about hosting

No image or loan input is uploaded. The host still handles ordinary requests and security data, and aggregate page visits are counted. That is different from zero internet data.

These tools help you prepare. They do not decide for you.

Inspect image details before sharing. Check official platform rules before uploading. Loan results are estimates, not offers or financial advice.
