These Terms of Service ("Terms") govern your use of Birder Diary for iOS ("the app") and its related online services (together, the "service"). By using the service, you agree to these Terms and the Privacy Policy.
You must be legally able to agree to these Terms. You may use Birder Diary for lawful purposes and must comply with applicable laws, regulations, and the rights of others.
The iOS app uses Sign in with Apple to help protect access. You are responsible for safeguarding your Apple account and device and for activity while signed in. Do not transfer, sell, or misuse access to the service, and contact us promptly if you believe your account or sign-in status is compromised.
You retain ownership of the photos, videos, notes, and other content you add. You are responsible for having the rights and permissions needed to use that content. You allow the app to process this content to the extent necessary to provide the features you request.
Species identification, regional, taxonomic, conservation-status, and other information provided by the service is for reference and may be incomplete, outdated, or inaccurate. Do not use it as the sole basis for scientific, medical, legal, emergency, navigation, conservation-enforcement, or other safety-critical decisions. You can review and correct your records.
The service offers free and membership features, and some features have usage limits. Specific benefits and limits are described in the app and on the purchase page. We will provide notice of changes as required by law and protect the benefits you have already purchased.
Purchases completed through Apple are also subject to Apple's applicable terms, billing, and refund rules. Non-waivable consumer rights prevail if they conflict with these Terms.
To keep the service safe and fair for everyone, please use its features responsibly. Do not interfere with the service, bypass authentication or usage limits, submit malicious or unlawful material, use automated means to overload or extract from the service, probe for vulnerabilities without permission, impersonate another person, or reverse engineer the service except where applicable law expressly permits it.
Intellectual property rights in the app and related content belong to us or the respective rights holders. Third-party content is subject to its own licenses, and these Terms do not restrict the rights granted to you under those licenses.
For third-party copyright and license information, see the Third-Party Notices.
Some features use operating-system, network, and related technical services. Their availability may depend on their own rules and network conditions. We are not responsible for independent third-party services beyond the extent required by applicable law.
We work to keep the service stable and reliable and may maintain and update it to improve features. Maintenance, network conditions, or other reasonable circumstances may cause temporary interruptions. We may also limit or suspend access when necessary to protect users and the service, address abuse, or comply with law.
You may sign out, uninstall the app, or otherwise stop using the service at any time. Uninstalling deletes the local diary and app data on that device, but the online account and related service records are not automatically deleted when the app is uninstalled. To request deletion of your online account and associated information, contact us as described in the Privacy Policy. Transaction, security, or audit records that must be retained by law may remain for the required period.
To the maximum extent permitted by law, the service is provided "as is" and "as available," without warranties of any kind, whether express, implied, or statutory. We do not warrant the accuracy of identification or location results, fitness for a particular purpose, or uninterrupted operation. Nothing in these Terms excludes warranties or rights that cannot lawfully be excluded.
To the maximum extent permitted by law, Birder Diary and its operators will not be liable for indirect, incidental, special, exemplary, or consequential damages, or for loss of data, profits, goodwill, or business opportunity arising from the service. This limitation does not apply where liability cannot legally be limited.
We may update these Terms as the service changes. We will post the revised Terms with a new last-updated date and provide additional notice where required. By continuing to use the service after revised Terms take effect, you agree to them to the extent permitted by law.
