--------------------------------------------------------------------------------
THE SHORT VERSION (for convenience only; the full terms below control)

  - Cella is one product. A license is for one person, costs a one-time fee
    (US$149) and includes every 1.x update.
  - You can try Cella free for 14 days, starting when you first launch it.
  - When the trial ends without a license key, Cella keeps working as a
    viewer: you can open, view, search and print. Marking up, measuring and
    saving need a license key.
  - One license key activates Cella on one computer and one iPad that you
    personally use (the iPad app is forthcoming).
  - Don't share your license key, redistribute the app, or work around the
    licensing.
  - The app checks for updates and, when you activate a key, verifies it. It
    never sends your documents anywhere.
  - The software comes without warranties, to the extent the law allows.

1. WHO THIS AGREEMENT IS WITH

This End User License Agreement ("Agreement") is between you and Sorted
Solution LLC ("Sorted Solution", "we", "us"). "You" means the individual who
installs or uses the Software, or, if you accept this Agreement on behalf of an
organization, that organization and its authorized users. By installing or
using the Software you agree to this Agreement. If you don't agree, don't
install or use the Software.

2. DEFINITIONS

"Software" means the Cella application for macOS, Windows and Linux (and, when
we release it, for iPad), including its extensions, updates we provide, and its
documentation. "Trial" means the free evaluation period described in Section 5.
"View-Only Mode" means the Software's viewing features, which are opening,
viewing, searching and printing documents, and which remain usable without a
License Key after the Trial ends. "Licensed Features" means all other features
of the Software, which currently include marking up, measuring and saving.
"License Key" means the key we or our reseller issue to you when you buy a
Cella license. "Device" means a single computer, or a single installation of an
operating system on a computer (including a virtual machine), or a single iPad,
on which the Software is activated.

3. TRIAL AND VIEW-ONLY LICENSE

Subject to this Agreement, we grant you a free, non-exclusive,
non-transferable license to install the Software and to use it during the
Trial, and to use View-Only Mode after the Trial ends, for personal or
commercial purposes, without a License Key.

4. CELLA LICENSE

4.1 Grant. When you buy Cella and receive a License Key, we grant you a
perpetual (subject to Section 11), non-exclusive, non-transferable license to
use the Licensed Features on one (1) computer and one (1) iPad that you
personally use. The computer may run any supported operating system.

4.2 One person per license. Each License Key is for one named individual. An
organization must buy one License Key for each person who uses the Licensed
Features. A person may not share a License Key with, or let it be used by,
anyone else.

4.3 Activation. The Software activates a License Key on each Device by
contacting our licensing service. You can free up a Device slot by choosing
"Remove License" on that Device. We may limit how often slots are moved to
prevent abuse.

4.4 Price and payment. The price of Cella is shown at the time of purchase and
is a one-time fee, not a subscription. Purchases are processed by Lemon
Squeezy, which acts as the reseller and merchant of record; its terms of sale
apply to the purchase transaction, including taxes and payment methods.

4.5 Refunds. Because you can try the Software free for 14 days before buying
(Section 5), all sales are final and we don't offer refunds, except where the
law requires one. When a purchase is refunded or charged back, the License Key
is revoked.

5. FREE TRIAL

You may evaluate the Licensed Features free of charge for fourteen (14) days,
one time per person, starting when you first launch the Software. When the
Trial ends, the Software runs in View-Only Mode and the Licensed Features stop
working until you enter a valid License Key; your documents are not affected.
You may not reset, extend or restart the Trial by any means.

6. UPDATES AND VERSIONS

6.1 A Cella license includes all updates to the major version you bought
(for example, all 1.x releases). We may offer later major versions (for
example, 2.0) as a paid upgrade, which you are not required to buy.

6.2 The Software can check for, download and install updates. You can turn
automatic update checks off in the Software's settings. Updates are subject to
this Agreement unless they come with different terms.

6.3 We are not obliged to provide updates, support or any particular feature,
and we may change or discontinue features of future versions.

7. RESTRICTIONS

Except as expressly allowed by this Agreement or by law that cannot be waived,
you may not:
  (a) sell, rent, lease, lend, sublicense or otherwise charge for the Software
      or a License Key, or transfer a License Key to someone else unless we
      approve the transfer in writing;
  (b) redistribute, mirror, bundle or repackage the Software — please send
      people to the official download page instead (distribution through
      package managers or repositories we publish or approve is allowed);
  (c) share, publish or generate License Keys, or remove, disable or work
      around the Software's licensing, Trial, View-Only Mode or activation;
  (d) reverse engineer, decompile or disassemble the Software, except to the
      extent applicable law expressly permits this despite this restriction;
  (e) remove or change any copyright, trademark or other notices; or
  (f) use the Software in violation of any law.

8. YOUR CONTENT

Your documents and files remain yours. The Software processes them on your
Device; we don't receive them.

9. THIRD-PARTY SOFTWARE AND SERVICES

9.1 The Software includes open-source components that are licensed to you
under their own licenses, listed in THIRD-PARTY-NOTICES.txt. Nothing in this
Agreement limits your rights under those licenses.

9.2 Third-party products you use with the Software — for example email apps,
word processors or PDF viewers — are provided by their own publishers under
their own terms. We are not responsible for them, and Cella is not affiliated
with or endorsed by their publishers unless stated.

10. PRIVACY

The Software does not collect or transmit the content of your documents. It
contacts our servers only to (a) check for updates, sending the app version,
license status and operating-system version, and (b) activate,
validate or remove a License Key, sending the key and a name for the Device.
Our payment provider receives the information you give it when you buy. See
our privacy policy at https://www.sortedsolution.com/privacy/ for details.

11. TERMINATION

This Agreement stays in effect until terminated. It ends automatically if you
materially breach it, and we may revoke a License Key used in breach of it
(including key sharing) or associated with a refunded or charged-back
purchase. When it ends you must stop using the Licensed Features and, for a breach
of Section 7, uninstall the Software. Sections 7 through 15 survive
termination.

12. DISCLAIMER OF WARRANTIES

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SOFTWARE IS PROVIDED "AS IS" AND
"AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. SORTED
SOLUTION DISCLAIMS ALL WARRANTIES AND CONDITIONS, EXPRESS OR IMPLIED,
INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
TITLE AND NON-INFRINGEMENT, AND ANY WARRANTY THAT THE SOFTWARE WILL BE
UNINTERRUPTED, ERROR-FREE OR COMPATIBLE WITH OTHER SOFTWARE, OR THAT
DOCUMENTS OR EXPORTS WILL BE FREE OF ERRORS.

13. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SORTED SOLUTION WILL NOT BE LIABLE
FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR
FOR ANY LOSS OF DATA, PROFITS, REVENUE OR BUSINESS, ARISING FROM OR RELATED TO
THE SOFTWARE OR THIS AGREEMENT, EVEN IF ADVISED OF THEIR POSSIBILITY. OUR
TOTAL LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU
PAID FOR CELLA IN THE TWELVE (12) MONTHS BEFORE THE CLAIM OR TEN US
DOLLARS (US$10).

14. CONSUMER RIGHTS

Some jurisdictions don't allow certain warranty exclusions or liability
limits, or give consumers rights that can't be changed by contract. Nothing in
this Agreement limits those rights; where they apply, the exclusions and
limits above apply only as far as the law allows.

15. GENERAL

15.1 Governing law. This Agreement is governed by the laws of the State of
Washington, USA, without regard to conflict-of-law rules, and the courts of
King County, Washington have exclusive jurisdiction, except where
consumer-protection law gives you the right to bring claims in your home
courts.
15.2 Export. You will comply with applicable export and sanctions laws.
15.3 Changes. We may update this Agreement for future versions of the
Software. The version that comes with a release applies to that release.
15.4 Entire agreement. This Agreement, together with the terms of sale that
apply to your purchase, is the entire agreement about the Software. If any
part is found unenforceable, the rest remains in effect. Our not enforcing a
provision is not a waiver.
15.5 Trademarks. "Cella" and "Sorted Solution" are
trademarks of Sorted Solution LLC.
15.6 Contact. Sorted Solution LLC, Bellevue, Washington, USA, hello@sortedsol.com.
