Making every card choice a little clearer.
Tapdi is a credit card manager for people in Vietnam. We help you understand each card's cashback conditions, fees and due dates, without your bank password.
Credit cards keep adding rewards, and conditions to match.
Every card has its own cashback rates, caps per statement cycle, merchant categories (MCC) and fees. With two or three cards in your wallet, it is hard to remember which card suits which purchase, which one has hit its cap, or how much is due this cycle.
Many people track this in spreadsheets or notes. Tapdi brings it into one place: record transactions, estimate cashback using each card's actual conditions, compare it with what the bank credits, and keep due dates in view.
Commitments that don't change
No bank password needed
Tapdi never asks for your bank username, password, OTP or full card number, through any channel.
Estimates are labelled as estimates
Cashback figures in Tapdi are estimates. Your bank decides the actual amount, and Tapdi helps you compare the two.
We don't sell personal data
Your data is used to provide the service. You can export or delete it at any time from Settings.
Built for Vietnamese law
Our Terms and Privacy Policy follow Vietnamese law, including the Personal Data Protection Law No. 91/2025/QH15.
How Tapdi makes money
You should know how we earn money, because it decides who we serve.
Paid plan
The Free plan needs no payment method. Plus is prepaid for a fixed term, never auto-renews, and adds tools for people who need more.
Disclosed referral links
If you open a card through a referral link in Tapdi, we may receive a fee from the partner. Referral fees never change the order of your personalised suggestions, and sponsored placements are always labelled.
Anonymised aggregate data
Tapdi may use aggregate statistics that cannot identify anyone for market research. Never names, emails, card numbers or individual transactions.
