What data do we collect, and how do we use it

Personal data

TreeSisters acts as the ‘controller’ of the personal data you provide to us. If you donate to us, we will usually collect basic personal data about you like your name, postal address, telephone number, email address and your bank details. We need this information to process your donation, GiftAid claims (if applicable), and to contact you about your donation.


When you join our mailing list, you provide permission for us to collect your name, country and email address. We use this personal data to contact you with newsletters, information and emails from TreeSisters. You may opt out of receiving any or all of these communications from us by clicking the ‘Unsubscribe’ link within the email or contacting our team at If you choose to withhold the requested information, we may not be able to provide you with certain services.


Sometimes we will request other information about you, such as your date of birth and gender. We will be very clear about why we are asking for such information; providing this data would be optional, and we would only do so with your specific consent and permission.


If you contact us through or communicate directly with a member of our team, we may store information about our interactions and relationship in our Customer Relationship Management tool, Salesforce. This is to support our team to help you quickly and efficiently. 


We may collect personal data from you in different circumstances, e.g. employment applications. Whenever we collect your personal data, we will provide the details of what we are collecting and storing, why, and for how long we will retain the information. 

Usage Data

We may also collect information on how our services are accessed and used. This Usage Data may include information such as your computer's Internet Protocol address (IP address), browser type, browser version, the pages of our Service that you visit, the time and date of your visit, the time spent on those pages, unique device identifiers and other diagnostic data. Data will be aggregated and the purpose of collecting and reviewing this data to allow us to improve our services and to detect, prevent and address technical issues.

Legitimate interests

Under data protection laws, there are a number of lawful reasons where we can use (or 'process') your personal information, including 'legitimate interests'. This means that we can process your personal information if we have a genuine and legitimate reason and we are not harming any of your rights and interests.


Some typical examples of when we might use the approach are for preventing fraud, maintaining the security of our system, data analytics, enhancing, modifying or improving our services, identifying usage trends and determining the effectiveness of our campaigns and fundraising.


Sharing or Transferring your information

We will never sell or rent your personal information to other organisations. We only disclose information to third parties or individuals when you have agreed that we may do so and in the following situations:


  • When we use other companies to support our operations or to provide services on our behalf, e.g. sending mail and emails, customer analysis, assessment and profiling, when using auditors/advisors or processing credit/debit card payments.

  • To enforce or apply our Terms and Conditions or if we believe that we need to do so to protect and defend the rights, property or personal safety of TreeSisters, our staff/volunteers/partners, our websites, and for other lawful purposes.

  • We may disclose aggregate statistics about our site visitors, supporters, and donors to describe our services and operations to prospective partners and other reputable third parties and for other lawful purposes, but these statistics won’t include any personally identifying information.

  • Your details may need to be shared if we run an event in partnership with other named organisations. We will be very clear about what will happen to your data when you register.

  • Under certain circumstances, TreeSisters may be required to disclose your Personal Data if required to do so by law or in response to valid requests by public authorities (e.g. a court or a government agency). 

Transfer of Data

The personal data we collect is processed by our team in the UK, supported by consultants in the US and France. Therefore, your information, including personal data, may be transferred to and maintained on computers located outside of your country, state, province, or other governmental jurisdiction where the data protection laws may differ from those of your jurisdiction. TreeSisters will always remain the ‘data controller’ and therefore UK data protection legislation and requirements will preside.

These third parties have access to your personal data only to perform these tasks on our behalf and are obligated not to disclose or use it for any other purpose.
