Process Flow

Design decisions

Should reminder notify privately or in group?

Reminder should be private to the user. Notification appears only on the user’s device and is not visible to others.

Should reminder resend the message?

No, Clicking the reminder should open the original message in the chat.

Can reminders repeat?

No, Reminder triggers once unless user sets it again.

What happens if the message is deleted?

If the message is deleted, the reminder is also removed automatically.
