The data allowance
What the free tier's 2 GB per connection, five connections a day and 5 GB a day actually mean, and what a subscription changes.
| Limit | Free | Subscribed |
|---|---|---|
| Data per connection | 2 GB | No per-connection limit |
| Connections per day | 5 | No daily limit |
| Data per day | 5 GB | No limit |
| Data per week | 25 GB | No limit |
| Data per month | 80 GB | No limit |
| Devices on one account | 10 | 10 |
2 GB per connection, 5 GB per day
Each connection can carry up to 2 GB, and the 2 GB starts fresh every time you connect. Use it up and the tunnel closes on its own; connect again and you have a fresh 2 GB. It's the data carried in both directions while that connection lasts — browsing, streaming, downloads, everything counts.
On top of that, the free tier has a cap of 5 GB a day, 25 GB a week and 80 GB a month, so five connections don't add up to 10 GB. While a connection is open, the 2 GB it may still use is held against the day's cap, so the app can say the day's data is used up a little before 5 GB has actually moved. When that happens it tells you when data is available again, even if you have connections left.
Five connections, then wait
Reconnecting to refresh the 2 GB counts against the five-a-day limit. Once you've used the day's five, the app tells you so and stops issuing new connections — it doesn't silently fail or connect you at a reduced quality. They come back one at a time rather than all together at midnight: one connection every 4 hours 48 minutes, and the app shows you the wait rather than a date.
Ten devices either way
A subscription removes the per-connection cap, the data limits and the daily connection count; it doesn't change how many devices can share the account. Up to ten devices on the free tier and ten on a paid one — see devices and linking if you need to attach another one, and the account number for what that requires.
What counts as "a device"
A device is identified by a key generated on it the first time the app runs — permanent, and not reset by reinstalling. That's what the ten-device limit actually counts, not how many times you've installed the app. The privacy policy explains exactly what that key is and isn't.
