Three ways, and all three open from the bot:
We neither ask for nor store your card details: the payment gateway handles the charge.
Where it is: Profile → Subscription and status.

Whenever you like. What was left of the previous plan is discounted, so you do not pay twice for the same days.
The change is immediate: the new limits apply as soon as the payment is confirmed.
The change applies when the period you already paid for ends. Until then you keep what you have.
When it drops, what you already had keeps working even if it exceeds the new plan’s limit: no channel or account is taken away; you simply cannot add more until you are within the limit. Nothing is deleted, and open positions are not closed.
The monthly plan renews by itself and is cancelled from Telegram whenever you like. It stays active until the end of the paid period, after which the account drops to the Shadow plan by itself.
The quarterly and yearly plans are a single payment: they do not renew by themselves, they expire on their date, and we warn you beforehand so you can decide. The quarter works out 10% cheaper than paying month to month, and the year 25%: that is three months free.
Because you can try the whole Pro plan free before paying, we do not give the money back. The exceptions are in the terms of use: a duplicate or erroneous charge, a failure of ours that prevents use of the service and that we do not resolve within a reasonable time, or where the law of your country requires it.
We may change prices with advance notice, and it never affects a period already paid for. On the yearly plan, your price is fixed until it expires.
