Terms Of Service
================

Last Updated: 12.4.2019

Welcome! Taler Systems SA (“we,” “our,” or “us”) provides a payment service
through our Internet presence (collectively the “Services”). Before using our
Services, please read the Terms of Service (the “Terms” or the “Agreement”)
carefully.

Overview
--------

This section provides a brief summary of the highlights of this
Agreement. Please note that when you accept this Agreement, you are accepting
all of the terms and conditions and not just this section. We and possibly
other third parties provide Internet services which interact with the Taler
Wallet’s self-hosted personal payment application. When using the Taler Wallet
to interact with our Services, you are agreeing to our Terms, so please read
carefully.

Highlights:
~~~~~~~~~~~

    • You are responsible for keeping the data in your Taler Wallet at all times
      under your control. Any losses arising from you not being in control of
      your private information are your problem.
    • We will try to transfer funds we hold in escrow for our users to any legal
      recipient to the best of our ability within the limitations of the law and
      our implementation. However, the Services offered today are highly
      experimental and the set of recipients of funds is severely restricted.
    • For our Services, we may charge transaction fees. The specific fee structure
      is provided based on the Taler protocol and should be shown to you when you
      withdraw electronic coins using a Taler Wallet. You agree and understand
      that the Taler protocol allows for the fee structure to change.
    • You agree to not intentionally overwhelm our systems with requests and
      follow responsible disclosure if you find security issues in our services.
    • We cannot be held accountable for our Services not being available due to
      circumstances beyond our control. If we modify or terminate our services,
      we will try to give you the opportunity to recover your funds. However,
      given the experimental state of the Services today, this may not be
      possible. You are strongly advised to limit your use of the Service
      to small-scale experiments expecting total loss of all funds.

These terms outline approved uses of our Services. The Services and these
Terms are still at an experimental stage. If you have any questions or
comments related to this Agreement, please send us a message to
legal@taler-systems.com. If you do not agree to this Agreement, you must not
use our Services.

How you accept this policy
--------------------------

By sending funds to us (to top-up your Taler Wallet), you acknowledge that you
have read, understood, and agreed to these Terms. We reserve the right to
change these Terms at any time. If you disagree with the change, we may in the
future offer you with an easy option to recover your unspent funds. However,
in the current experimental period you acknowledge that this feature is not
yet available, resulting in your funds being lost unless you accept the new
Terms. If you continue to use our Services other than to recover your unspent
funds, your continued use of our Services following any such change will
signify your acceptance to be bound by the then current Terms. Please check
the effective date above to determine if there have been any changes since you
have last reviewed these Terms.

Services
--------

We will try to transfer funds that we hold in escrow for our users to any
legal recipient to the best of our ability and within the limitations of the
law and our implementation. However, the Services offered today are highly
experimental and the set of recipients of funds is severely restricted.  The
Taler Wallet can be loaded by exchanging fiat currencies against electronic
coins. We are providing this exchange service. Once your Taler Wallet is
loaded with electronic coins they can be spent for purchases if the seller is
accepting Taler as a means of payment. We are not guaranteeing that any seller
is accepting Taler at all or a particular seller.  The seller or recipient of
deposits of electronic coins must specify the target account, as per the
design of the Taler protocol. They are responsible for following the protocol
and specifying the correct bank account, and are solely liable for any losses
that may arise from specifying the wrong account. We will allow the government
to link wire transfers to the underlying contract hash. It is the
responsibility of recipients to preserve the full contracts and to pay
whatever taxes and charges may be applicable. Technical issues may lead to
situations where we are unable to make transfers at all or lead to incorrect
transfers that cannot be reversed. We will only refuse to execute transfers if
the transfers are prohibited by a competent legal authority and we are ordered
to do so.

Fees
----

You agree to pay the fees for exchanges and withdrawals completed via the
Taler Wallet ("Fees") as defined by us, which we may change from time to
time. With the exception of wire transfer fees, Taler transaction fees are set
for any electronic coin at the time of withdrawal and fixed throughout the
validity period of the respective electronic coin. Your wallet should obtain
and display applicable fees when withdrawing funds. Fees for coins obtained as
change may differ from the fees applicable to the original coin. Wire transfer
fees that are independent from electronic coins may change annually.  You
authorize us to charge or deduct applicable fees owed in connection with
deposits, exchanges and withdrawals following the rules of the Taler protocol.
We reserve the right to provide different types of rewards to users either in
the form of discount for our Services or in any other form at our discretion
and without prior notice to you.

Eligibility
-----------

To be eligible to use our Services, you must be able to form legally binding
contracts or have the permission of your legal guardian. By using our
Services, you represent and warrant that you meet all eligibility requirements
that we outline in these Terms.

Financial self-responsibility
-----------------------------

You will be responsible for maintaining the availability, integrity and
confidentiality of the data stored in your wallet. When you setup a Taler
Wallet, you are strongly advised to follow the precautionary measures offered
by the software to minimize the chances to losse access to or control over
your Wallet data. We will not be liable for any loss or damage arising from
your failure to comply with this paragraph.

-------------------------

The Taler Wallet is released under the terms of the GNU General Public License
(GNU GPL). You have the right to access, use, and share the Taler Wallet, in
modified or unmodified form. However, the GPL is a strong copyleft license,
which means that any derivative works must be distributed under the same
license terms as the original software. If you have any questions, you should
review the GNU GPL’s full terms and conditions at

payments using the Taler protocol, assuming your use is compatible with an
official release from the GNU Project that is not older than two years.

Your use of our services
------------------------

When using our Services, you agree to not take any action that intentionally
imposes an unreasonable load on our infrastructure. If you find security
problems in our Services, you agree to first report them to
security@taler-systems.com and grant us the right to publish your report. We
warrant that we will ourselves publicly disclose any issues reported within 3
months, and that we will not prosecute anyone reporting security issues if
they did not exploit the issue beyond a proof-of-concept, and followed the
above responsible disclosure practice.

Limitation of liability & disclaimer of warranties
--------------------------------------------------

action regarding: Failures, disruptions, errors, or delays in processing that
you may experience while using our Services; The risk of failure of hardware,

    Third Party Content contained in or accessed through our Services.

Any other terms, conditions, warranties, or representations associated with
such content, are solely between you and such organizations and/or
individuals.

Limitation of liability
-----------------------

To the fullest extent permitted by applicable law, in no event will we or any
of our officers, directors, representatives, agents, servants, counsel,
employees, consultants, lawyers, and other personnel authorized to act,
acting, or purporting to act on our behalf (collectively the “Taler Parties”)
be liable to you under contract, tort, strict liability, negligence, or any
other legal or equitable theory, for:

    or consequential damages of any kind whatsoever resulting from:

       Wallet software or that may be transmitted to or through our services by
       any third party (regardless of the source of origination), or

(b) any direct damages.

These limitations apply regardless of legal theory, whether based on tort,
strict liability, breach of contract, breach of warranty, or any other legal
theory, and whether or not we were advised of the possibility of such
damages. Some jurisdictions do not allow the exclusion or limitation of
liability for consequential or incidental damages, so the above limitation may
not apply to you.
