Issue

Users are not notified when they surpass their disk storage limits on their subscription plan, resulting in unexpected overage charges without warning.

Problem Statement

A user was charged 50% above their current subscription rate due to exceeding their disk limit, but received no notifications (email or in-app) that they had surpassed the limit. This is particularly problematic for budget-conscious users (e.g., students) who expect to be alerted before incurring overage charges.

Context

From the discussion:

• User exceeded their plan's disk allocation (smallest plan is 100GB)
• No email or in-app notifications were sent
• User was charged overage fees without any heads-up
• This impacts the ability to recommend the service to students with tight budgets

Acceptance Criteria

• Notify users when approaching their disk limit (e.g., at 80-90% utilization)
• Notify users when they exceed their disk limit
• Notifications should be sent via email and/or in-app
• Consider whether to implement hard limits to prevent going over (noted as tricky for bandwidth)

Notes

The team acknowledged this is a valid concern and agreed notifications should be implemented as customers approach their budget limits.
