These terms govern your use of the Birdy Android application ("the App") provided by AlbIT AB (org. no. 559593-7607, Solna, Sweden) ("we", "us").
1. Age requirement
You must be at least 13 years old to use Birdy.
2. License
We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your personal, non-commercial use. You may not:
- Redistribute the App itself outside of the Google Play Store distribution.
- Reverse-engineer the App except where permitted by mandatory law.
- Use the App to scrape, harvest, or aggregate data from third-party services.
Third-party content and components in the App (species photos, species texts, the machine-learning models, fonts and open-source libraries) are licensed to you under their own licenses, listed in section 4 and in the App under Settings → About. Nothing in these terms limits the rights those licenses give you, and the restrictions above do not apply to that content.
3. AI classification is approximate
Birdy uses machine-learning classifiers to suggest bird species from images and audio. Classifications are approximate and may be wrong. Birdy is an educational and field-journaling tool, not a substitute for a trained ornithologist, a published field guide, or expert identification when accurate identification matters (e.g., legal hunting, sensitive surveys, conservation work).
4. Content sources and licenses
The App combines our own work with content and components from others, most of them under open licenses:
- Species texts. The description and migration texts are summaries that an AI model (Claude, from Anthropic) wrote from the Wikipedia articles about each species, in Swedish and English. They are adaptations of Wikipedia text and are shared under the Creative Commons Attribution-ShareAlike 4.0 license (CC BY-SA 4.0).
- Photos. The species photos come from Wikimedia Commons. Each one is in the public domain, dedicated to it under CC0, or licensed under CC BY or CC BY-SA (version 2.0, 3.0 or 4.0) by its author. We resize and convert the photos and do not otherwise change them; each photo remains under its own license.
- Species list and names. The selection of species and the English names follow the Western Palearctic list (VP11) of BirdLife Sweden's taxonomic committee, checked against the IOC World Bird List v14.1 (F. Gill, D. Donsker & P. Rasmussen, eds.), licensed under CC BY 3.0. Most Swedish names come from Wikidata, which is in the public domain (CC0), and some from BirdLife Sweden's official list. The global red-list category (IUCN) also comes from Wikidata.
- Photo identification. The AIY Birds V1 model, © Google, licensed under the Apache License 2.0.
- Sound identification. The BirdNET-Lite model by the K. Lisa Yang Center for Conservation Bioacoustics, Cornell Lab of Ornithology, Cornell University, licensed under CC BY-NC-SA 4.0 (Attribution-NonCommercial-ShareAlike). Birdy uses the model unchanged. Sound identification is free for all users and is never part of Premium.
- Map. Map tiles © MapTiler, map data © OpenStreetMap contributors (Open Database License).
- Fonts. DM Serif Display and Caveat, licensed under the SIL Open Font License 1.1.
- Open-source libraries. Kotlin, Compose Multiplatform, AndroidX, TensorFlow Lite and other libraries, most of them under the Apache License 2.0.
The App shows the credits for photos, texts, models and libraries, with their licenses, under Settings → About.
5. Premium purchases
Premium features (the personal finds map, PDF export of your field journal, season statistics and seven premium field badges) are sold via Google Play Billing as either:
- An annual subscription that renews automatically each year at the price shown in Google Play. You can cancel at any time in Google Play (Play Store → Payments & subscriptions → Subscriptions); Premium then stays active until the end of the period you have paid for and does not renew.
- A lifetime one-time purchase, which is non-recurring.
Refunds follow Google Play's refund policy. Audio-identification is not behind a paywall and remains free for all users.
6. No warranty
The App is provided "as is" without warranties of any kind, either express or implied, including but not limited to fitness for a particular purpose, accuracy, or non-infringement. To the extent permitted by law, we disclaim all warranties.
7. Limitation of liability
To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, special, consequential, or exemplary damages arising from your use of the App. Nothing in these terms limits liability that cannot be limited under mandatory consumer law.
8. Termination
We may terminate or suspend access to the App at any time, with or without notice, if you violate these terms. You may stop using the App at any time by uninstalling it.
9. Governing law
These terms are governed by Swedish law. Disputes are subject to the exclusive jurisdiction of the courts of Stockholm, Sweden, except where mandatory consumer law gives you the right to bring claims in your local court.
10. Changes
We may update these terms from time to time. Material changes will be noted in release notes. The "Last updated" date above reflects the current version.
