In general, we collect information about the actions that you take on our website, and we use this information to provide our services to you. You can access most features without creating an account or providing us with personal information. We use Google Analytics, a web analytics tool, to help us analyze data on website traffic and page views. We take steps to protect the personal information you provide us, such as by limiting access to the information to trained staff and volunteers, and only sharing your information as needed to provide services to you. We also provide you with certain choices regarding your personal information, and we aim to honor your preferences.
Depending on how you use our website and its features, we may collect information about you (sometimes referred to as "personal information"). The type of personal information we collect from or about you may include: name, email address, location information, and any other information you choose to provide to us.

We may also collect information about you from third parties. In particular, if you have an OpenStreetMap (OSM) account, we may receive your user ID and display name for that account and information regarding your actions on OSM. Additionally, if you choose to authenticate using a social media account (e.g., Facebook or Google), we may collect, store, and use information you make available through that social media account. We treat any personal information we receive from these third parties consistent with this Privacy Policy.
When you use our website, we, or third parties operating on our behalf, use cookies and similar technologies to collect information about the features that you access and use, and about the browser and computer or device you use to access our website.

Missing Maps uses cookies to help us understand and remember your preferences and make our website more easily navigable and useful for you. We also use cookies to help us monitor and track how features are being used and evaluate the effectiveness of email campaigns.

We may also maintain and use information in de-identified or aggregated forms that do not identify you. We will retain your information for no longer than is necessary for the purposes for which it is processed.
For those visitors whose personal information is subject to EU data protection laws, the legal bases for processing your information as set out in this Privacy Policy are as follows: (1) The processing is necessary in order to fulfill our contractual commitments to you; (2) The processing is necessary for us to comply with a legal obligation; (3) We have a legitimate interest in processing your information – for example, to provide and update our services, to improve our services so that we can offer you an even better user experience, to safeguard our services, to communicate with you, to measure, gauge, and improve the effectiveness of our services, and better understand user retention and attrition, to monitor and prevent any problems with our services, and to personalize your experience; or (4) You have given us your consent – for example before we place certain cookies on your device and access and analyze them later on.
We may share information about you in limited circumstances for the purposes described in this Privacy Policy and with appropriate safeguards on your privacy and the security of your personal information. In particular:
We use appropriate administrative, technical, and physical measures designed to prevent unauthorized access, improper use or disclosure, unauthorized modification or unlawful destruction or accidental loss of personal information. Although we exercise reasonable care in providing secure transmission of information and storage of the information provided to us through our website, no method of transmission over the Internet, and no means of electronic or physical storage, is absolutely secure. Accordingly, we cannot ensure or warrant the security of any information you transmit to us.
Certain local laws establish rights for consumers who are subject to their protections. For example, the European Union's General Data Protection Regulation provides for the following rights for individuals whose data is collected in the EU:
While these rights are not absolute – e.g., we do not have to delete your data if we need the data for compliance with a legal obligation – and they are not legally required in every jurisdiction in which we collect data, Missing Maps wants to make it easy and straightforward for all our users to enjoy these rights. We provide you with several choices when it comes to information about you:
If you have any questions or otherwise would like to contact us about one of these rights, you can email info@hotosm.org to ask a question or request to exercise one of your rights. We will consider all requests and provide our response within the time period stated by applicable law. We may request you provide us with information necessary to confirm your identity before responding to your request – this is solely to protect you, and we will not use any of the information you provide us to confirm your identity for anything other than confirming your identity.
Our website may include links to third-party websites and services that are not owned or controlled by us, such as GitHub, social media platforms like Twitter, Facebook, and LinkedIn. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party websites or services. If you choose to use any third-party websites or services, the collection, use, and disclosure of your information on those websites will be subject to the privacy policies of these websites and services.
We encourage youth to volunteer with Missing Maps under the supervision of their parent or guardian, and are committed to protecting the privacy of children who use our website. We do not knowingly collect personal information from children under 16. However, depending on how you use our website, we may collect and use information about your child that you provide to us. Before we collect any such information, we will seek your permission. If we become aware we are processing the data of a child under the age of 16 without parental consent, we will take reasonable steps to delete such information as required under applicable laws. If you believe we might have personal information from or about a child under 16, please contact us at info@hotosm.org.
We may modify this Privacy Policy from time to time. All such changes will be reflected on this page and the date of revision will be noted at the top of the Privacy Policy. Please check the Policy periodically for updates.
