How it works
1) Create a group and set the contribution amount, frequency and rotation.
2) Invite members by phone number.
3) Record each contribution and mark payouts as they happen.
4) Everyone can see what’s due and what’s next—no spreadsheets required.

Privacy & security

• Data is transmitted securely and stored on Firebase
• We collect only what’s needed to run your groups (name, phone, group activity)
• You can request account deletion at any time via in-app support

Note
Achup is an organizer for Njangi groups. It is not a bank and does not move money;
all payments happen between group members outside the app.
