Question 1

Is it safe to upload my bank CSV to Leak Engine?

Accepted Answer

Yes. Your CSV is processed locally in your session. No passwords, no bank login, and no third-party access to your live accounts. Your data never leaves your session.

Question 2

How does ghost subscription detection work?

Accepted Answer

Leak Engine matches every recurring charge in your CSV against your last login date. Any service billing you that you haven't used in 90+ days is flagged as a ghost subscription.

Question 3

What is a duplicate charge?

Accepted Answer

A duplicate charge is when the same transaction appears more than once — sometimes under slightly different merchant names. Leak Engine catches these instantly and calculates your refund window.

Question 4

Is Leak Engine free to use?

Accepted Answer

Yes. The free tier reveals your single biggest money leak with no credit card required. Premium unlocks all leaks, 5-year projections, and full ghost subscription audits for $9.99/month.

Question 5

What bank CSV formats does Leak Engine support?

Accepted Answer

Leak Engine supports standard CSV exports from most major banks. Simply export your transaction history as a CSV file from your bank's website and upload it directly.
