A paid plan covers a number of devices rather than one:
| Plan | Devices |
|---|---|
| Free | No limit |
| Pro | Up to 5 |
| Pro+ | Up to 10 |
What counts as a device
An installed app on a phone, tablet or computer — Android, iOS or the desktop app. Each one registers itself with your account when you sign in.
Using Docuslice in a browser does not count. Web sessions are recorded, but they never consume a slot. Sign in on a library computer for ten minutes and nothing is used up — and buying a plan in a browser does not use one either.
The count starts at zero when you pay
Devices you used while on the free plan are not counted retroactively. The moment you buy Pro or Pro+, your used-device count starts from zero, regardless of how many devices you had signed in on before.
Those existing devices are still there and still work; each takes a slot the next time it connects while your plan is active, not all at once on the day you paid.
When the limit is reached
Signing in on a new device beyond your limit is refused with a clear message rather than a silent failure. You have three options:
- Remove a device you no longer use, then sign in again on the new one.
- Upgrade — Pro to Pro+ takes you from five to ten.
- Use the browser app on that machine, which needs no slot.
Removing a device
Open the devices screen in your account settings — it appears once you are on a paid plan, which is also when the limit starts to apply. It lists every registered device by name, with the current one marked. Remove any you no longer use.
The slot is freed immediately. If that device signs in again later it takes a slot again, which is what you want — removal is not a ban.
Why there is a limit at all
A one-time purchase with no device limit is a licence for an unlimited number of people. The limit is set high enough that a household's real devices fit comfortably, and it exists so the plans can stay one-time purchases rather than subscriptions.
