Draft — not in force

This is a draft. It has not been reviewed by a lawyer and it binds nobody.

It was written from how the Perun system actually behaves today, so that counsel has something accurate to correct instead of a blank page or a generic template. It is not the published document, it creates no rights and no obligations, and it must not be relied on. Nothing here is legal advice.

Highlighted text marks a fact about the company that has deliberately not been invented. Every one of them must be replaced before this page is published.

Terms of service

The terms you agree to when you rent a power bank from a Perun station, including billing, returns and liability.

Draft 0.1 — prepared 1 September 2026 — not in force

1.Who we are

Perun is a self-service power bank rental network. You find a station in a café, bar or other venue, scan the QR code on it with the Perun app, take a charged power bank, and return it to any Perun station when you are done.

Perun is operated by COMPANY LEGAL NAME, a COMPANY LEGAL FORM entered in COMPANY REGISTER under number COMPANY UIC, VAT number COMPANY VAT NUMBER, registered address COMPANY REGISTERED ADDRESS, represented by COMPANY REPRESENTATIVE. In these terms we, us and Perun mean that company, and you mean the person renting.

Reach us at support@perun.green or COMPANY PHONE. The full registration details are on the company details page.

2.What these terms cover

These terms cover two things: your Perun account, and every individual rental you start. Creating an account accepts them. Each rental is then a separate contract, concluded at the moment you confirm the rental in the app.

They take effect on EFFECTIVE DATE. They are published in English and Bulgarian; in case of conflict the PREVAILING LANGUAGE text governs.

3.Who can use Perun

To rent you need all three of these:

  • to be 18 or older and legally able to enter into a contract;
  • a Perun account — a mobile number, or Sign in with Apple;
  • a payment card accepted by Stripe, which processes payments for us.

One account per person. Do not let anyone else rent on your account: the rental, and the charge, are yours.

4.Your account

There is no password. You sign in either with your mobile number and a one-time code sent by SMS, or with Sign in with Apple. That means anyone who controls that number or that Apple ID can sign in as you — tell us at support@perun.green straight away if you lose control of either.

You can change your name and profile picture in the app at any time, and you can delete the account (section 13). What we do with the data is in the privacy notice.

5.Starting a rental

  1. Find a station on the map in the app and scan the QR code on it.
  2. The app shows you the rate for the tariff you select before you confirm. The amount held on your card is shown on the rental itself, under Activity, once it has started.
  3. When you confirm, we ask your card issuer to authorise a hold for that amount. A hold is not a payment — see section 7.
  4. If the hold succeeds, the station releases a power bank. The rental starts when the station reports that a bank has physically come out, not when you tap confirm.

If no bank comes out, no rental starts. Our system cancels the authorisation automatically a few minutes after an unlock the station never confirms, and nothing is charged. If your banking app still shows the hold after that, it will drop off on its own — the timing there belongs to your bank, not to us.

You may hold only one rental at a time. Until the current one is closed, you cannot start another.

6.What a rental costs

You pay for time. The price is a fixed amount per started unit of time, with a cap on how much can be billed in each window. The rate, the unit, the cap and the window are set per country and are shown in the app before you confirm.

The figures shown in the app when you confirm are the ones that apply. They are copied onto your rental at that moment, so a later change to our prices never re-prices a rental that has already started.

In Bulgaria, at the date of this draft, that is 0.99 EUR per started 90 minutes, capped at 5.28 EUR in any 24 hours — the cap being the equivalent of eight hours of use. Some worked examples:

40 minutes
0.99 EUR. One started 90-minute unit; a started unit is a charged unit.
3 hours
1.98 EUR. Two started units.
24 hours
5.28 EUR. The cap for one 24-hour window. The running total reaches it after about seven and a half hours and then stops until the window resets.
3 days
15.84 EUR. Three capped windows.
About 5 days 4½ hours, and anything longer
30.00 EUR. At that point the running total reaches the amount held on your card, and it cannot go any higher.

We can never take more than we held. Whatever the arithmetic comes to, the amount actually taken is clamped to the amount you authorised at the start.

There is no subscription, no membership fee, no deposit, and no separate fee for unlocking a bank.

7.The hold, and when we take the money

Starting a rental places an authorisation — a hold — on your card. In Bulgaria that is 30.00 EUR by default, and the exact figure for your rental is shown on the rental itself under Activity. A hold reserves money without transferring it. Your available balance drops by that amount and no payment has been made.

When you return the bank we take the amount owed, and no more. The rest of the hold is released. How soon the released part reappears is decided by your card issuer, not by us — a few working days is normal.

If the amount owed comes to zero — you took a bank and put it straight back, for instance — we cancel the authorisation instead of taking anything.

We take payment once per rental. You will not see a second charge for the same rental.

8.Long rentals and the seven-day authorisation

A card authorisation lapses after about seven days, whether or not anyone has used it. So if your rental is still running at 6 days and 12 hours, we take what is owed at that moment and the rental carries on. In practice the running total has reached the hold well before then, so this takes the full held amount.

We send a push notification about a day beforehand, if you have notifications switched on, so that returning the bank first is a real option.

After that payment, nothing further can be charged for that rental, however long it runs on. The bank is still ours and you still have to bring it back (sections 9 and 10), but the money side of that rental is closed.

9.Returning the bank

Return the bank to any free slot at any Perun station — not only the one you took it from. The rental ends, and the clock stops, at the moment the station reports the bank locked into a slot.

The app shows how many free slots each station has, so you can pick one before you set off. If you arrive and the station is full, find another in the app, or write to support@perun.green and we will sort the billing out with you.

Do not post a bank back to us and do not leave it with venue staff. A bank that is not locked into a slot is not returned, and the rental keeps running.

10.Damage, loss, and banks that do not come back

Look after the bank while you have it. Do not open it or take it apart, do not submerge it, do not charge it from anything other than a Perun station, and do not use it in a way its markings prohibit. It stays our property throughout.

If a bank is never returned, the rental stays open and the charge follows section 8 — which means the most it can ever come to is the amount held at the start. We do not charge a separate loss, damage or replacement fee, and these terms do not create one. After a while we will close the rental, either keeping what has already been taken or releasing the hold if nothing has been, so that you can rent again.

If a bank is faulty, will not charge your device, or is already damaged when you get it, report it in the app or to support@perun.green. Do not keep paying for a bank that does not work — return it to end the rental, and then tell us.

11.Your right to withdraw

You make this contract at a distance, so EU consumer law (Directive 2011/83/EU, as transposed where you live) gives you 14 days to withdraw without giving a reason. It applies in two places, and they work differently.

Your account
You may withdraw from the account relationship within 14 days of creating it. It costs nothing and there is nothing to pay back — the simplest way is to delete the account in the app.
An individual rental
The 14 days run from the day the rental is concluded. But a rental is a service you ask us to begin immediately, so: if you withdraw while it is running, you pay for what you have actually used up to that point; and once the rental has been fully performed — the bank returned and the payment settled — the right of withdrawal is lost, provided you expressly asked us to start straight away and acknowledged that you would lose it.

To withdraw, tell us in a clear statement — an email to support@perun.green is enough. You may use the form below but you do not have to. We will refund what is due within 14 days of being told, to the same payment method, at no cost to you.

12.Rules of use

While you are using Perun, do not:

  • damage, move, open or interfere with a station or a bank;
  • try to release a bank other than through the app;
  • sell, hire out or lend a bank to someone else;
  • use Perun for anything unlawful, or in a way that harms other customers or the venues hosting our stations;
  • attempt to probe, disrupt or gain unauthorised access to our systems or the station hardware.

13.Suspension, and closing your account

We may suspend or close your account if you break these terms, if a payment fails or is reversed, if we reasonably suspect fraud, or if the law requires it. Where we can, we will tell you why and give you a chance to put it right.

You can delete your account at any time in the app, under Settings. It will refuse while a rental is unfinished — return the bank first, and if the payment is still settling, wait a few minutes and try again. What deletion does to your data is set out in the privacy notice; the rental records themselves are kept, because they are financial records.

We may also stop offering the service, in a place or altogether. If we do, we will stop starting new rentals and release any hold that has not been taken.

14.If something goes wrong

We will provide the service with reasonable care and skill. Nothing in these terms limits liability that cannot be limited by law — in particular liability for death or personal injury caused by our negligence, liability for fraud, and any liability under mandatory consumer-protection or product-liability rules.

We are not responsible for loss that was not reasonably foreseeable, and we do not promise that a particular station will be in service, stocked, or have a free slot at a particular moment.

15.Changes to these terms

We may change these terms. The new version is published here, and where a change matters to you we will tell you in the app or by email before it takes effect.

A change never applies to a rental that has already started. Your rental is governed by the terms and the prices in force when you confirmed it. If you do not accept a change, stop using Perun and delete your account.

16.Complaints, law and disputes

Please write to support@perun.green first. We will acknowledge your complaint and try to put it right.

These terms are governed by GOVERNING LAW. If you are a consumer, that does not take away the protection of the mandatory rules of the country you live in. Disputes may be brought before COMPETENT COURTS.

You may also be able to use an out-of-court dispute resolution scheme: ADR BODY. You can complain to the consumer protection authority at CONSUMER PROTECTION AUTHORITY.
