Madeen tools FAQ
Do Madeen tools require bank login?
No. Every Madeen web tool runs in your browser against our published card catalog. You never connect a bank account or share credentials.
Which tool should I use first?
Start with the Rewards Maximizer for everyday category spend, then use the transfer bonus tracker or live offers feed when planning travel redemptions.
How often is catalog data updated?
Madeen refreshes the underlying RewardsCC catalog on a weekly schedule. Each tool page shows the catalog snapshot date used for its calculations.
