This article matches the site Billing & Cancellation Policy and current App metering. Prices follow checkout; minutes charged follow the prompts when you end practice.
In one line
- Buy: Personal subscription, minute add-on packs, Material Store (content access).
- Spend: Self practice / regular live pair by effective duration (round up to whole minutes, min 1); Learn vocab / listening / speaking drills only when AI scoring runs and items score; placement and invite free pair are free by default.
What you buy (inflows)
| Type | What you get | Where |
|---|---|---|
| Personal subscription | Monthly subscription minutes (usually no rollover) | Me → Purchase center |
| Minute add-on packs | Permanent practice minutes | Me → Purchase center |
| Material Store | Content access, not a minute pack; bonus minutes only if the SKU says so | Learn → Material Store |
Treat “add-on” as two different things: time add-ons vs material SKUs. A subscription is not all-access materials; buying materials is not unlimited AI scoring.
What you spend (one minute pool)
Order: benefits → subscription minutes → add-on minutes.
| Feature | Charged? | How |
|---|---|---|
| AI speaking (self) | Yes | Effective duration: ceil to whole minutes, at least 1 |
| Live pair (regular) | Yes | Same duration rule |
| Invite · free pair (acquisition) | Free by default | UI says no practice minutes; if ops enables billing, follow the App |
| Speaking placement | Free | No minutes; not an official certificate |
| Material Store | At purchase | Listed price for access |
| Vocab / listening / speaking drills | Conditional | See below |
Drill AI scoring (not “1 item = 1 minute”)
Doing the exercise itself does not consume minutes.
If you choose AI scoring at End, you are charged once for scored items only. Skip / scoring never started / unscored items → no charge.
Rates are by skill in blocks (same rule as the End dialog)—not flat 1 item = 1 minute:
| Skill | Block (summary) | Examples |
|---|---|---|
| Vocabulary | ~10 items per minute block | 1–10 scored items often 1 minute |
| Listening | ~4 items per minute block | 1–5 often 1; 6–7 often 2 |
| Speaking items | ~2 items per minute block | 1 → 1; 3 → 2; 5 → 3 |
At least 1 minute when any item can be scored. Trust the End dialog’s “up to X minutes”; settlement uses the same rule on scored count. Details: AI scoring.
Family / Teaching
Children / students spend their own benefits plus allocated minutes; AI scoring may be switched in Space settings → Practice page settings. See Minutes pool.
