+This directory contains the privacy policy (template) for exchange
+operators.
+
+
+Dependencies
+============
+
+Generating a new Privacy Policy requires Sphinx, LaTeX with babel
+packages for all supported languages.  On Debian, you should
+at least install:
+
+$ apt install python3-sphinx sphinx-intl texlive-lang-german texlive-lang-english
+
+(NOTE: List may be incomplete.)
+
+
+Updating the Privacy Policy
+===========================
+
+The master file with the Privacy Policy is 'pp.rst'.
+
+If you make substantial changes, you MUST change the "PP_VERSION"
+in contrib/Makefile.am to the new Etag.
+
+To begin the translation into other languages after editing the master
+file, run
+
+$ make gettext
+
+to generate the master PO file. Then, run
+
+$ sphinx-intl update -p _build/locale/ -l de -l fr -l it
+
+to update the PO files for the various languages (extend the list of
+languages as necessary). The PO files for the translators are kept
+at locale/$LANG/LC_MESSAGES/pp.po for the language $LANG.
+
+Once all PO files have been updated with new translations, run
+
+$ make update-pp
+
+in the "contrib/" directory to generate all of the formats.  The
+respective make rule calls the '../update-pp.sh' script in the
+contrib/ directory, which calls the 'Makefile' in the pp/
+directory for the various supported languages and file formats
+and then moves the generated files to the target directory
+('contrib/pp/$LANG/$VERSION.$FORMAT')
+
+
+Adding a new language
+=====================
+
+To add a new language $LANG, add $LANG to "PP_LANGUAGES" in
+'contrib/Makefile.am' and run
+
+$ sphinx-intl update -p _build/gettext -l $LANG
+
+to generate the PO template.

-<h2>OVERVIEW</h2>
-
-<p>Your
-privacy is important to us. We follow a few fundamental principles:
-We don’t ask you for personally identifiable information (defined
-below). That being said, your contact information, such as your phone
-number, social media handle, or email address (depending on how you
-contact us), may be collected when you communicate with us, for
-example to report a bug or other error related to the Taler Wallet.
-We don’t share your information with third parties except when
-strictly required to deliver you our Services and products, or to
-comply with the law. If you have any questions or concerns about this
-policy, please reach out to us at privacy@taler-systems.net.
-</p>
-
-<h2>HOW YOU ACCEPT THIS POLICY</h2>
-
-<p>By
-using our Services or visiting our sites, you agree to the use,
-disclosure, and procedures outlined in this Privacy Policy.
-</p>
-
-<h2>WHAT PERSONAL INFORMATION DO WE COLLECT FROM OUR USERS?</h2>
-
-<p>The
-information we collect from you falls into two categories: (i)
-personally identifiable information (i.e., data that could
-potentially identify you as an individual) (“Personal
-Information”), and (ii) non-personally identifiable information
-(i.e., information that cannot be used to identify who you are)
-(“Non-Personal Information”). This Privacy Policy covers both
-categories and will tell you how we might collect and use each type.
-</p>
-<p>We
-do our best to not collect any Personal Information from Taler Wallet
-users.  We believe that the Taler Wallet never transmits personal
-information to our services without at least clear implied consent,
-and we only process and retain information with a strict business
-need.  That being said, when using our Services, we inherently have
-  to collect the following information:
-</p>
-<p>
-<ul>
-	<li>Bank
-	account details necessary when receiving funds from you to top-up
-	your wallet or to transfer funds to you when you are being paid via
-	Taler.  At the current experimental stage, only the pseudonym and
-	password you entered in the bank demonstrator is stored.</p>
-	<li>The
-	amounts being withdrawn or deposited, with associated unique
-	transaction identifiers and cryptographic signatures authorizing the
-	transaction. Note that for purchases, we cannot identify the buyer
-	from the collected data, so when you spend money, we only receive
-	non-personal information.</p>
-	<li>When
-	you contact us. We may collect certain information if you choose to
-	contact us, for example to report a bug or other error with the
-	Taler Wallet. This may include contact information such as your
-	name, email address or phone number depending on the method you
-	choose to contact us. </p>

+Privacy Policy
+==============

+Last Updated: 11.12.2019

+This Privacy Policy describes the policies and procedures of Taler Systems SA
+(“we,” “our,” or “us”) pertaining to the collection, use, and disclosure of
+your information on our sites and related mobile applications and products we
+offer (the “Services” or “Taler Wallet”). This Privacy Statement applies to
+your personal data when you use our Services, and does not apply to online
+websites or services that we do not own or control.
+
+
+Overview
+--------
+
+Your privacy is important to us. We follow a few fundamental principles: We
+don’t ask you for personally identifiable information (defined below). That
+being said, your contact information, such as your phone number, social media
+handle, or email address (depending on how you contact us), may be collected
+when you communicate with us, for example to report a bug or other error
+related to the Taler Wallet. We don’t share your information with third

+products, or to comply with the law. If you have any questions or concerns
+about this policy, please reach out to us at privacy@taler-systems.net.
+
+
+How you accept this policy
+--------------------------
+
+By using our Services or visiting our sites, you agree to the use, disclosure,
+and procedures outlined in this Privacy Policy.
+
+
+What personal information do we collect from our users?
+-------------------------------------------------------
+
+The information we collect from you falls into two categories: (i) personally
+identifiable information (i.e., data that could potentially identify you as an
+individual) (“Personal Information”), and (ii) non-personally identifiable
+information (i.e., information that cannot be used to identify who you are)
+(“Non-Personal Information”). This Privacy Policy covers both categories and
+will tell you how we might collect and use each type.
+
+We do our best to not collect any Personal Information from Taler Wallet
+users. We believe that the Taler Wallet never transmits personal information
+to our services without at least clear implied consent, and we only process
+and retain information with a strict business need. That being said, when
+using our Services, we inherently have to collect the following information:
+
+   * Bank account details necessary when receiving funds from you to top-up your wallet or to transfer funds to you when you are being paid via Taler. At the current experimental stage, only the pseudonym and password you entered in the bank demonstrator is stored.
+
+   * The amounts being withdrawn or deposited, with associated unique transaction identifiers and cryptographic signatures authorizing the transaction. Note that for purchases, we cannot identify the buyer from the collected data, so when you spend money, we only receive non-personal information.
