distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:

2.7. Conditions

Sections 3.1, 3.2, 3.3, 3.4, and 4 are conditions of the licenses
granted in Section 2.1.

3. Responsibilities
-------------------

3.1. Distribution of Source Form

All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.

3.2. Distribution of Executable Form

If You distribute Covered Software in Executable Form then:

(a) such Covered Software must also be made available in Source Code
    Form, as described in Section 3.1, and You must inform recipients of
    the Executable Form how they can obtain a copy of such Source Code
    Form by reasonable means in a timely manner, at a charge no more
    than the cost of distribution to the recipient; and

(b) You may distribute such Executable Form under the terms of this
    License, or sublicense it under different terms, provided that the
    license for the Executable Form does not attempt to limit or alter
    the recipients' rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).

3.4. Notices

You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.

4. Protecting privacy
---------------------

4.1. Protecting Personal Information

Personal Information is not subject to ownership, by either You or the
Subject. Instead, privacy is a fundamental human right. Determining if
and how Personal Information is Processed is an essential part of
privacy. This clause aims to guarantee that You respect this
fundamental human right.

You must ensure that Personal Information is Adequately Encrypted
wherever possible.

This clause 4 does not apply if and in so far as You are the Subject.

4.2. Processing Adequately Encrypted Personal Information

You may Process Personal Information by means of Covered Software, or
by means of a Larger Work, without obtaining the prior authorization of
clause 4.3, only if and in so far as necessary for providing Your
service to the Subject, and provided that this Personal Information is
Adequately Encrypted. In all other cases, the terms of clause 4.3
apply.

4.3. Processing Unencrypted Personal Information

You may not Process Unencrypted Personal Information by means of
Covered Software or by means of a Larger Work, unless You obtain prior
authorization from the Subject. You will ensure that such authorization
is always:

(a) For a specific period of time;

(b) For a specific, pre-determined, communicated and unchangeable
    purpose;

(c) Based on clear and understandable information about the specific
    period of time and the specific purpose;

(d) Based on a separate agreement, and not concealed in general terms
    and conditions or click through agreements;

(e) Accompanied by an offer to fairly compensate the Subject for the
    value derived from Processing Personal Information that is not
    Adequately Encrypted, which value must be validated in hindsight;

The specific period of time listed under clause 4.3 (a) may be an
unlimited period of time only if and in so far as the Personal
Information is a Static Data Set. If the Personal Information is not a
Static Data Set, the specific period of time may not be longer than two
years, which term may be extended for another period of two years. Such
extension may not occur automatically, and requires renewed
authorization in accordance with this clause 4.3.

The terms of this clause 4.3 apply to Processing Adequately Encrypted
Personal Information for other purposes than the purposes described in
clause 4.2 as well.

4.4. Requirements for third party access

If You want to provide access to Personal Information to a third party,
then You must ensure that the Subject is a party to the transaction
(whether that transaction is for a fee, or not) with regard to their
Personal Information, so that the Subject can authorize that access.

The criteria for authorization listed in clause 4.3 apply in full.

In addition, you must ensure that the third party complies with the
obligations of clause 4.3 and 4.4, even if the third party does not use
Covered Software or a Larger Work to Process the acquired Personal
Information.

This Clause does not apply if and in so far as the Subject initiates
the process of providing access to such third party, for instance by
sending a limited Static Data Set to a recipient of their choice.

4.5. Revoking authorization

If a Subject does not extend the authorization previously given, You
will delete all their Personal Information and after deletion You must
send proof of deletion to the Subject and subsequently delete such
proof.

4.6. Control by Subject

You must ensure that a Subject has full control over their Personal
Information. This includes allowing the Subject to download all their
Personal Information in a format regularly used for such Personal
Information. The Subject is at all times responsible for safekeeping of
the encryption keys.

4.7 Restrictions for Processing Aggregate Information

If you want to Process Personal Information to generate Aggregate
Information, the terms of clause 4.3 apply. In addition:

You may only Process Personal Information to generate Aggregate
Information if and in so far as it’s reasonable to assume that the
chance of extracting Personal Information from the Aggregate
Information is negligible.

Creating Aggregate Information may not serve the purpose of obtaining
more Personal Information about a Subject or extracting Personal
Information from such Aggregate Information. Furthermore, You must do
everything in Your power to prevent anyone, including Yourself, from
trying to extract Personal Information about a Subject from Your
Aggregate Information or Your Inferences.

If you want to provide access to or sell  Aggregate Information to a
third party, You must ensure that the terms of clause 4.7 (b) and (c)
apply in all material respects to such third party, even if the third
party does not use Covered Software or a Larger Work to Process the
Aggregate Information

Provided You comply with the terms of this clause 4.7, you may use
Aggregate Information to generate Inferences.

4.8 General Restrictions on Processing Personal Information

You may not Process Personal Information by means of Covered Software
or by means of a Larger Work, if the purpose of such Processing is:

(a) Surveillance;

(b) Tracking;

(c) Influencing or recording political views;

(d) identifying, or obtaining information about, other persons than the
    Subject.

5. Inability to Comply Due to Statute or Regulation
---------------------------------------------------

If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.

6. Termination
--------------

6.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.

6.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.

6.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.
