Third-party software notices
DRY Share is proprietary software, but it uses the open-source components and services listed below. Their licenses permit commercial use subject to their respective notice, source-availability, and other conditions. DRY Share does not claim ownership of these components.
Web app and PWA
MapLibre GL JS 5.7.1
The map view uses MapLibre GL JS, distributed under the BSD 3-Clause license and containing separately attributed portions under BSD and MIT terms. The complete copyright notices, conditions, and disclaimers are included in the vendored MapLibre license file.
OpenFreeMap and OpenStreetMap data
When a user explicitly loads the default map, DRY Share obtains map resources from OpenFreeMap. Attribution to OpenFreeMap, OpenMapTiles, and OpenStreetMap contributors is displayed in the map itself. OpenFreeMap is a hosted service rather than software included in DRY Share.
Backend and distribution images
PostgreSQL 17
DRY Share deployments use the PostgreSQL database management system. PostgreSQL is distributed under the PostgreSQL License:

Rust libraries
The DRY Share backend uses Rust libraries under permissive MIT, Apache-2.0, BSD, Unicode, Zlib, and compatible dual-license terms. The WebAuthn implementation includes files under the Mozilla Public License 2.0. The unmodified corresponding source is available from the webauthn-rs source repository; DRY Share modifications to MPL-covered files, if any, must be made available under MPL-2.0. A complete versioned component inventory is maintained with the release SBOM and repository licensing report.
Native Android and iOS apps
The native apps use React, React Native, Hermes, and react-native-safe-area-context. Their copyright and MIT license notices, together with the applicable AndroidX Apache-2.0 notices, are available inside each app under Security → Open-source notices.
The native client core uses UniFFI 0.30.0 under MPL-2.0. When a release includes that core, its corresponding source is available from the UniFFI 0.30.0 source tree; modifications to MPL-covered files must remain available under MPL-2.0.
Complete component inventory
Release images include a CycloneDX SBOM. The repository also contains a generated third-party license inventory covering the Rust and installed mobile JavaScript dependency graphs. Because operating-system packages and resolved Gradle/CocoaPods artifacts depend on the actual release build, the release SBOM remains the authoritative inventory for each shipped artifact.
