Photo LedgerStreet maps and data credits
The app uses MapLibre Native for map rendering, OpenFreeMap street-map services and OpenMapTiles data/schema with OpenStreetMap contributors. These are different components, not satellite imagery or a Google Maps service.
Map data credit includes © OpenStreetMap contributors; OpenStreetMap data is available under the Open Database License (ODbL). Preserve the required map/service attributions when viewing or exporting map imagery, including the applicable OpenFreeMap and OpenMapTiles credits. A stamp template is not permission to remove them.
This web page does not replace map credits in the app or exported photos/reports. Review the OpenFreeMap terms and provider privacy information for its service. Other providers apply their own policies.
Map and application software licences
MapLibre Native is open-source software under its BSD 2-Clause licence. OpenMapTiles distinguishes its software/schema/style licences from the OpenStreetMap data licence; see its project and licensing information rather than assuming one licence covers every layer.
The app is built with Flutter and third-party packages, each subject to its own notices. Open Settings → About and licenses to reach the app’s licence information. These website links supplement, rather than replace, notices distributed with the app.
Bundled fonts
Photo Ledger bundles Noto Sans, Noto Devanagari and Noto Bengali fonts and their applicable SIL Open Font License 1.1 notices. The font files and copyright/license texts remain subject to their own terms. Read the bundled notices and the SIL Open Font License information.
The Matrixbreach website has separate typography: DM Sans and IBM Plex Mono loaded from Google Fonts. Their web requests are described in Privacy Policy.
Interface translation attribution
Some bundled interface translations were generated during development with Google Translate. The app retains the applicable Powered by Google Translate attribution. These translations are drafts and may contain mistakes.
This does not mean photos, addresses or notes are sent to translation services while you use the app. Language text is bundled. Google Translate is a separate provider; no affiliation or endorsement is implied.
App artwork and provider identity
Matrixbreach’s approved Survey Lens V4B artwork is used for this product. Its illustrated rooftop thumbnail and sample address are brand artwork, not a live map, a personal capture or a configured satellite service. No trademark registration or completed legal clearance is asserted.
Product and provider names identify their respective products/services. Matrixbreach does not claim affiliation with Susamp, Google, OpenStreetMap or the other referenced providers. For credit questions contact connect@matrixbreach.com.
