When a Subscription Ends

Your logger keeps recording and nothing is deleted. Everything you could see the day before stays visible — only new readings are held back, until you subscribe again. Alerts stop.

A subscription can end for several reasons: you unsubscribed the logger, a renewal payment didn't go through, or a free trial finished without a plan being paid for. What happens to the logger and its data is the same in every case. If it was a failed payment, there's also a short recovery path — see If a renewal payment failed.

Every subscribed logger shows the date it's paid through in the Subscription column on the Devices page — Ends followed by a date, or Renews followed by a date if it's set to renew automatically. The subscription runs to that date and stops there.

What ends, and what doesn't

Your logger is unaffected. It keeps taking readings on its schedule, keeps uploading them, and keeps its name, folder, and configuration. Nothing about the hardware changes and nothing needs reconfiguring later.

Your data is kept. Everything the logger has recorded is stored, including everything it records while it isn't covered.

Everything you could see, you keep seeing. Every reading up to the point coverage ended stays visible — in ZENTRA Cloud, in downloads and exports, and through the API. A subscription ending never takes away data you could see the day before.

Only new readings are held back. From the moment coverage ends, what the logger records isn't shown to you until it's subscribed again. On the Devices page, expanding an unsubscribed logger shows its recent sensor readings blurred, with a Subscribe link above them — and the time of its most recent measurement, unblurred. That timestamp tells you the logger is still collecting and still uploading, even while the newest readings are out of view.

Alerts stop, and this is the part to plan around. A logger without a subscription doesn't trigger alerts. Readings are still arriving and still being kept, but nothing is being watched, so no notification is sent — and an alert that would have fired is not sent later once you subscribe again. Data can be caught up on. A notification you needed at the time can't be.

Held back is not deleted

Blurred readings aren't missing readings. The values are there and are still arriving — what's in place is a restriction on reading them while the logger isn't paid for.

Subscribe the logger again and the gap fills in. Every reading taken while it wasn't covered appears, and stays visible from then on, whether or not you renew again later. There's no gap left behind, nothing to repair, and nothing you need to ask us to recover.

Data is revealed once and stays revealed. The only readings you can't see are the ones collected since coverage last ended.

The exception is alerts, which run in the moment and can't be replayed.

Readings from before you subscribed

The same principle works backwards. Subscribing a logger reveals its full history, including readings it took before it was ever subscribed to anything — and that history stays visible afterwards.

You don't lose the beginning of a record by subscribing a logger late, any more than you lose the middle of one by paying late.

Getting it back

Subscribe the logger again from the Devices page, the same way you subscribed it the first time — see Subscribe and unsubscribe devices.

Your data becomes visible again once the payment clears, not when you select Checkout.

If you unsubscribed a logger and changed your mind, and its Ends date hasn't passed yet, re-subscribing costs nothing — it's still paid for.

If a renewal payment failed

Your organization's subscriptions renew once a year, on your renewal date. The charge goes to your Available Balance first, and anything left over goes to your default payment method.

If that payment doesn't succeed, ZENTRA Cloud doesn't quietly retry and it doesn't extend your subscriptions. Three things happen at once:

• The affected loggers go back into your cart, carrying the plans they were renewing.
• Their auto-renew is switched off. They won't be charged again until you check out.
• Nothing is extended. Each logger stays covered until the Ends date it already had, then stops being covered.

Your credit is safe. If part of the renewal was going to be paid from your Available Balance, that balance isn't consumed by a payment that didn't complete. The invoice stays open until it can be paid in full, so nothing is spent until the whole amount is.

To fix it:

1. From Setup, select Billing. In the Payment Method card, add a working card and make it the default — see Set up billing for your organization. If your organization holds enough Available Balance to cover the charge, you don't need a card at all; balance is always spent first, and you can top it up from Add Usage.
2. Open your cart, check the loggers and plans listed are the ones you want, and select Checkout.

Your loggers are covered again when the payment clears, not when you select Checkout. If the card is declined again, they stay in the cart and you can retry. Auto-renew comes back on for the loggers you check out, so next year's renewal is set up again.

If you never paid your first invoice, there's a separate case that looks similar. If the very first invoice for a brand-new subscription is never paid, the subscription is cancelled outright rather than retried, so nobody is billed for loggers that were never paid for. The fix is the same: put the loggers in your cart and check out.

Avoiding an unplanned ending

• Keep a working default payment method on file, or enough Available Balance to cover the renewal. Balance is always spent first, so an organization holding enough of it renews without a card being involved. Cards expire, and a card that worked last year may not work this year.
• Check your renewal date. Your Billing page shows when the next charge is due and what it's estimated to be, under Annual Renewal.
• Watch loggers with their own dates. A logger that renews before your organization's annual renewal date is listed separately on the Billing page, under Next Invoice.
