TransferTimeTokyo Updater - Third-Party Notices
===============================================

The updater executable and its packaging toolchain use CPython, PyInstaller,
PyInstaller hooks, Pillow, pypdf, cryptography, cffi, pycparser, tzdata, Tcl,
and Tk. The exact license texts collected from the pinned build environment are
included below THIRD_PARTY_LICENSES; LICENSE_INDEX.txt records their versions
and SHA-256 hashes. Runtime timetable data is downloaded directly by each user
and is not included in the executable or release ZIP.

Tokyo Metro printable timetables (personal profile only)
---------------------------------------------------------

The updater can retrieve printable station timetable PDFs published on Tokyo
Metro's official website for local personal use. It resolves the edition valid
for the target date, validates the station, line, direction, service-day
sections, and departure times, and caches validated edition metadata and PDFs
for 24 hours. A failed refresh does not replace the validated last-good cache.
This source is always personal-only and is rejected by the public profile.
Downloaded PDFs, extracted timetable data, caches, and generated timetable
PDBs are not included in release packages and must not be redistributed as part
of a public build. Publication on a website does not by itself grant additional
redistribution rights; users remain responsible for the source terms.

Public Transportation Open Data Center (ODPT)
----------------------------------------------

The updater can retrieve rail and bus data at runtime from the Public
Transportation Open Data Center. For GTFS-only bus datasets, it also reads
permitted ODPT CKAN dataset pages at a low rate and selects a currently valid
Basic/open official download resource. Dataset availability and the applicable
license are stated in the ODPT catalog. Data marked CC0 may be used under
CC0. Data marked CC BY 4.0 must retain the attribution required by its catalog
entry. Version 0.1.5 does not automatically extract dataset-specific attribution;
users must review and retain it when selecting a source. ODPT Basic License data
is fetched with each user's token and is not included or redistributed here.
ODPT Basic remains an optional alternative source for Tokyo Metro and requires
a token supplied by the user. The token is not stored in the PDB, log, or
release ZIP.

Tokyo Metropolitan Bureau of Transportation data exposed as CC BY 4.0 via
ODPT remains attributed to the Tokyo Metropolitan Bureau of Transportation
and the Public Transportation Open Data Center. Keep the applicable catalog
entry and fetch date with any publication; the updater does not record the
exact CKAN resource metadata automatically.

Public Transportation Open Data Challenge 2026
----------------------------------------------

Challenge-limited data is available only for development intended for entry
in the Public Transportation Open Data Challenge 2026 and only during its
license period. It is not a blanket personal-use license. The submission
deadline is 2027-01-11 23:59 JST and permission to use Challenge data ends on
2027-03-14. Challenge datasets are excluded from the updater's normal operator,
ODPT CKAN, and GTFS Data Repository automatic candidates. Challenge data,
caches, and reconstructable timetable PDBs are not included in this package
and must not be redistributed.

GTFS-JP and GTFS Data Repository
--------------------------------

The updater can discover currently valid Tokyo CC0/CC BY feeds through GTFS
Data Repository API v2, download a user-selected GTFS-JP URL, or read a local
ZIP at runtime. Repository feeds are re-resolved to the resource valid on each
update. Every feed keeps its own publisher and license; version 0.1.5 does not
record the complete dataset-specific attribution text in the PDB. No feed ZIP
is bundled here. Users must review the source metadata before use, and CC BY
feeds require the attribution stated by that feed. A catalog entry grants no
rights beyond its stated license.

JR East station timetables (personal profile only)
---------------------------------------------------

The updater can retrieve public station timetable HTML from JR East at a low
rate for local personal use. It follows the current weekday and weekend/holiday
pages from a stable station page and caches validated HTML for six hours. This
source is always personal-only, is rejected by the public profile, and is not
included in release packages or published timetable PDBs.

Cabinet Office national-holiday CSV
-----------------------------------

The updater can retrieve the Japanese national-holiday CSV directly from the
Cabinet Office. Source: Cabinet Office, Government of Japan, "National
Holidays" CSV. Cabinet Office website content is available under the Public
Data License 1.0 unless a different condition is stated on the source page.
The CSV is not bundled here.
