2. Information We Collect
Account information. When you register, we collect information such as your email address, display name, and preferences (e.g. language, timezone). Your display name can be anything you choose — it does not need to be your real name.
Password. Your password is securely hashed using industry-standard algorithms. We never store passwords in plain text.
Usage data. We collect basic usage data to improve the Service.
Contributions. Content you submit to the Service (corrections, additions, photographs) is stored and associated with your account.
3. How We Use Your Information
We use your information to operate and improve the Service, including account authentication, email verification, contribution attribution, and any other purposes related to the Service.
4. Information Sharing
We may share your information when required by law, with service providers who assist in operating the Service, or as otherwise described in this policy.
5. Data Security
We protect your data using HTTPS encryption, password hashing, and access controls. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security. We are not responsible for data breaches resulting from circumstances beyond our reasonable control.
6. Your Responsibilities
You are responsible for the information you provide to the Service. We recommend not using your real name as your display name if you wish to remain anonymous. You are responsible for maintaining the security of your account credentials. Do not share your password with others.
7. Data Retention and Deletion
You may request deletion of your account and personal data by contacting us at [email protected]. Deletion requests are processed within 90 days. Contributions you have made may remain on the Service in anonymized form as part of the community dataset.
8. Cookies
We use cookies for authentication, session management, and to improve the Service. Third-party services integrated into the Service may also set cookies.
9. Children's Privacy
The Service is not directed at children under the age of 16. We do not knowingly collect personal information from children under 16. If you believe a child has provided us with personal data, please contact us so we can remove it.
