| Cancelling your plan | Retention flows, hidden links, and "contact us" hurdles — the pattern the FTC fined Chegg $7.5M over. | One click in the customer portal. Same place you started. |
| Previously-free features | Moved behind a paywall over time — a driver of Quizlet's ~1.4★ consumer rating. | The core study loop stays free. We never retroactively lock what was free. |
| What gets metered | Your access to content you already created or unlocked can be gated to pressure an upgrade. | Only AI generation is metered. Saved decks, notes, and history are never capped or deleted. |
| Seeing your limits | Caps discovered mid-workflow, often at the moment you need the feature most. | Every metered action shows "X of Y left" before you start it. No mid-workflow ambush. |
| Renewals & charges | Silent renewals and trial-to-paid conversions land as surprise statement lines. | We email you before every charge — trials included. A silent charge is a defect, not a tactic. |
| Ads | Consumer complaints span billing friction and access; attention is monetized in the market broadly. | No ads. Ever. You're the customer, not the product. |
