Publicly available information

We may use publicly available sources to keep your records up to date and check for changes of address and undertake data cleaning activity. This allows us to better direct our resources and efforts, manage supporter relationships and ensure data remains accurate, up to date and compliant. We may obtain this publicly available information directly or from third parties or other trusted source lists deemed reliable in the relevant country. We may also use trusted third-party providers to undertake data cleaning activities on our behalf.

When administering legacy gifts, we may occasionally be required to collect information relating to non-professional (lay) executors who are administering estates in which we have a legacy entitlement. Executors may provide their details to us themselves or, where appropriate, we may access the probate registries in order to obtain their details as listed within a deceased’s will. We may also receive this information from third parties who undertake searches of probate registries on our behalf.

We may collect information about you from publicly available sources to help us understand more about you as an individual and your ability to provide financial support for our charitable programs and activities; including, by carrying out wealth screening, a process which uses trusted third-party partners to automate some of this work. We may use information gathered from public sources alongside the information you provide to undertake analysis of who might be willing to financially support HSI and to understand the preferences of our supporters about events, communication and services. By doing this, we can focus conversations we have with you about fundraising in the most effective way, and ensure that we provide you with an experience as a donor or potential donor which is appropriate for you.

Ways information about you is used

We may use the information you voluntarily provided to contact you regarding animal-related issues we feel you may be interested in, to keep you updated regarding HSI’s programs, and to extend an invitation to you to support our programs. We may also directly upload voluntarily provided information into third-party platforms that have provided us with assurances that they process personal information under suitable data protection arrangements and security controls, such as Facebook and Google, in order to serve content-specific advertisements. We participate in Facebook’s “Custom Audiences” and “Lookalike Audiences” which enables us to display advertisements to our existing or potential supporters via Facebook or to suppress certain HSI advertisements from our existing supporters’ Facebook feeds (e.g. an advertisement directed at signing a petition when you have already signed it). In order to do this, we provide supporter name, email address, city, zip and telephone number to Facebook to enable them to determine if you are a registered account holder with Facebook. Your data is sent in an encrypted format that is deleted by Facebook if it does not match with a Facebook account. Before the data is uploaded by Facebook for the matching process, the information is hashed and will be unidentifiable at an individual level. Hashing is a type of cryptographic security method that turns your identifiers into randomized code and cannot be reversed. Depending on your settings our advertisements may then appear when you access Facebook and on your Facebook feed, as well as on other third-party websites and applications. For more information please read the Facebook Business page about Custom Audiences and Facebook’s Data Policy.

We may use your device’s physical location to provide you with personalized location-based services and content.

We may also send information to the people whose e-mail addresses you provide when forwarding HSI electronic content. When we do so, our sole intent is to enlarge our family of informed animal advocates and organizational supporters. Every recipient of our electronic communications can quickly and easily “opt out” of future such communications by following the instructions on any electronic communication we send.

From time to time, we may make the information you have voluntarily given to us (excluding credit card information and text messaging originator opt-in data and consent, neither of which will be disclosed to third parties), available to third parties for marketing purposes, including HSI’s affiliate organizations or sponsors and licensees that provide special programs or services we think you might find interesting or beneficial. HSI uses very strict standards in determining which reputable companies become sponsors and licensees, to ensure that such organizations are committed to the protection of visitors’ privacy and committed to the goals of HSI. If your volunteered personal information will be used in any manner other than as stated above, such use shall be specifically posted. If you wish to update or remove your information, or if you do not wish your information to be shared with affiliated third parties, please e-mail us at You may also unsubscribe at any time in every issue of our newsletters.


From time to time, HSI may link to other websites not affiliated with HSI. HSI attempts to link only to those websites which also respect a visitor’s privacy and the goals of HSI. However, HSI cannot be responsible for the content or policies of third-party websites. Please check with these third-party organizations or companies for their specific privacy policies. If you find inoperable links or are concerned about any of the sites that HSI currently links to, please inform HSI by contacting us at


HSI uses generally accepted, industry-standard security systems, software, and encryption technologies — Secure Sockets Layer (SSL) — for the secure transfer of personal and financial data and to protect against unauthorized access to HSI servers, equipment, and other components of our online presence. This includes using industry-standard security systems to protect credit card processing information. Our web servers are hosted off-site at multiple, physically secure facilities with limited access.
