Technologies ("Licensor"). By installing, copying, or otherwise using BillKaro
(the "Software"), Licensee agrees to be bound by the terms of this Agreement.
If Licensee does not agree, Licensee must NOT install or use the Software.

       executables, libraries, data files, documentation, updates, patches,
       and components distributed by Licensor.

       including product, customer, supplier, sale, and ledger records.


2. LICENSE GRANT

   Subject to the terms of this Agreement and payment of all applicable fees,
   Licensor grants Licensee a limited, non-exclusive, non-transferable,
   non-sublicensable, revocable license to install and use the Software on the
   number of devices permitted by the purchased License Key, solely for
   Licensee's internal retail business operations.


3. RESTRICTIONS

   Licensee shall not, and shall not permit any third party to:
   (a) copy, modify, adapt, translate, or create derivative works of the
       Software;
   (b) reverse-engineer, decompile, or disassemble the Software except to the
       extent expressly permitted by applicable law;

   (d) remove, alter, or obscure any proprietary or copyright notices in the
       Software;
   (e) use the Software in any manner that violates applicable laws,
       regulations, or third-party rights;
   (f) bypass, disable, or tamper with license verification, hardware
       binding, audit logging, or any other security mechanism in the Software.


4. OWNERSHIP

   The Software is licensed, not sold. Licensor retains all right, title, and
   interest in and to the Software, including all intellectual property rights
   therein. No rights are granted to Licensee other than those expressly stated
   in this Agreement.


5. DATA HANDLING AND PRIVACY CONSENT

   5.1 LOCAL OPERATION. The Software runs primarily offline on Licensee's
       device and stores Business Data in a local database.

   5.2 OPTIONAL DATA TRANSMISSION. Certain features may transmit Business
       Data outside Licensee's device, including but not limited to:
         (a) cloud database synchronization to a MySQL server,
         (b) automated daily / monthly business reports sent by email,
         (c) anonymized crash diagnostics returned to Licensor.

   5.3 EXPLICIT CONSENT REQUIRED. Each feature listed in clause 5.2 is OFF
       BY DEFAULT and will not transmit any data unless Licensee has given
       explicit, separate consent through the in-app Privacy & Consent screen,
       and has enabled that specific feature. Licensee may withdraw consent
       at any time; on next start of the Software, the relevant feature will
       cease to transmit data.

   5.4 LICENSEE OBLIGATIONS. Licensee is solely responsible for compliance
       with all applicable data-protection, privacy, tax, and record-keeping
       laws regarding any personal data of customers, employees, suppliers,
       or other individuals stored in or processed through the Software.
       Licensor processes Business Data only as a data processor on behalf of
       Licensee and only for features Licensee has expressly enabled.


6. LICENSE KEY AND HARDWARE BINDING

   The Software requires a valid License Key. License Keys are cryptographically
   bound to a hardware identifier of the device on which the Software is first
   activated. Licensee may request a key reissue subject to Licensor's
   reasonable verification procedures and any applicable reissue fee.


7. UPDATES

   Licensor may, at its sole discretion and without obligation, provide
   updates, patches, or new versions of the Software. Updates are subject to
   this Agreement unless they are accompanied by a separate license. Licensee
   acknowledges that updates may modify or remove features.


8. DISCLAIMER OF WARRANTIES

   THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY
   KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY WARRANTIES OF
   MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR
   ACCURACY. LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED,
   ERROR-FREE, OR FREE FROM HARMFUL COMPONENTS, OR THAT ANY DATA STORED IN OR
   TRANSMITTED BY THE SOFTWARE WILL BE SECURE OR NOT OTHERWISE LOST OR DAMAGED.


9. LIMITATION OF LIABILITY

   TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL
   LICENSOR BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL,
   EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUES, BUSINESS,
   DATA, USE, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT
   OR THE USE OF, OR INABILITY TO USE, THE SOFTWARE, EVEN IF LICENSOR HAS BEEN
   ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. LICENSOR'S TOTAL CUMULATIVE
   LIABILITY UNDER THIS AGREEMENT SHALL NOT EXCEED THE GREATER OF (i) THE
   AMOUNT PAID BY LICENSEE FOR THE LICENSE KEY IN THE TWELVE (12) MONTHS
   PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (ii) ONE THOUSAND
   PAKISTANI RUPEES (PKR 1,000).

    Licensee shall indemnify, defend, and hold harmless Licensor and its
    affiliates, officers, employees, and agents from and against any claim,
    loss, liability, damage, or expense (including reasonable legal fees)
    arising out of or relating to (a) Licensee's use of the Software in
    violation of this Agreement or any applicable law, (b) any Business Data
    or personal data processed through the Software, or (c) any third-party

    respect to the Software and supersedes all prior or contemporaneous
    understandings, whether written or oral.


15. SEVERABILITY
