GhostPay — Commercial License
Copyright (c) 2026 Jack Durand. All rights reserved.

1. GRANT
   The purchaser receives a non-exclusive, perpetual license to use, modify and
   self-host the GhostPay software ("the Software") according to the tier bought:

     SINGLE SHOP  — one production shop/storefront (one public endpoint).
     UNLIMITED    — any number of production shops owned by the purchaser.
     RESELLER     — as UNLIMITED, plus the right to rebrand, bundle and resell the
                    Software (or modified versions) to third parties, including
                    white-labelling without attribution.

2. UPDATES
   Free updates for 12 months from purchase (lifetime for RESELLER). New major
   versions may be sold separately after that period.

3. RESTRICTIONS
   - You may not resell the Software as-is in source form unless you hold RESELLER.
   - You may not remove or alter the license/copyright notes in the source headers.
   - One license per purchaser identity; sharing a purchased copy publicly
     ("here it is for free") is normal and permitted, reselling it is not.

4. SUPPORT
   Support is best-effort by the published contact channel: 12h target response.
   Full refund if the built-in self-test (`ghostpay.py selftest`) fails on the
   purchaser's machine and the issue is not resolved.

5. NO WARRANTY
   THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
   IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
   FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE
   AUTHORS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN
   ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION
   WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

6. THIRD PARTIES
   The BIP39 English word list (2048 words) embedded in the source is the one
   published in the Bitcoin BIPs repository (MIT licensed) and is included for
   mnemonic support. No other third-party code is bundled: the rest is standard
   library Python.

7. NOT FINANCIAL ADVICE
   Address derivation, rate conversion and explorer data are provided as a
   convenience. You (the licensee) are responsible for verifying that funds
   reached your wallet.
