Last Updated: October 14, 2022


This Privacy Policy (“Policy”) describes how Overflow App Inc. (“Overflow,” “we,” “us,” or “our”) collects, uses, protects, and shares your personal information on our website, online platforms, and any other websites that link to this Privacy Policy (collectively, “the Services”).

This Policy does not apply to the personal information processed, maintained, or otherwise managed by Overflow solely for the benefit of, on the behalf of, or under the exclusive direction or control of our business customers in Overflow’s capacity as a service provider in the context of our Overflow for Corporations service. We have no direct relationship with the individuals whose personal information we process on behalf of our business customers. To learn more about the processing of your personal information in that context, please consult the relevant business customer’s privacy policy.

Personal Information We Collect

Information you provide to us:

  • Account information. When you register for our Services, we collect your first and last name, password, email address, billing address, phone number, and any additional information you provide in order to create an Overflow account.
  • Organization Account Creation. If you create an account on behalf of a non-profit, we will collect your name, email, telephone number, job title, and certain additional information applicable to the non-profit for which you are creating the account, like the employer or tax identification number, the organization’s data brokerage account and financial information, ZIP code, size, mission of the non-profit and any information you provide in order to create an Overflow account.
  • Donor Information.  As a donor or a financial advisor on behalf of a donor, you may provide us various information related to the contributions that the donor may make to third parties through Overflow, including but not limited to details regarding your contributions, tax documentation, and other related information.
  • Financial Information. When you submit a non-cash contribution through Overflow, you provide us and our service providers with your name, email address, physical address, phone number, brokerage, brokerage number (which we encrypt when storing in our database), securities portfolio information for any brokerage accounts you link to the Services, the amounts and recipients of your contributions, date of settlements, and any other personal information and financial details required to initiate a stock contribution. To process certain contributions we may need to help you create accounts with third party brokerages. Doing so may require us to collect additional information like your social security number, Government-issued photo ID, date of birth & questions about your sources of income, including name of employer and employment status. Please note, however, that we collect that information solely to help establish your account with the third party brokerage.
    • For cash contributions, our payment processors will collect the financial information necessary to process your payments, such as your financial account information, payment card number, and authentication details. We do not maintain payment card information on our servers.
    • For contributions made by cryptocurrencies, we will collect the information necessary to process your contribution, including the amount and recipient of your contribution.
  • Communications with Overflow. When you contact us via a contact form, email, text message, helpdesk, or by any other method, we may collect your name, email address, phone number, mailing address, company, professional title or role, transaction information about your contributions, and the contents and nature of your correspondence with us.  We may also solicit details surrounding your specific transaction.
  • Marketing data. When you sign up to receive notifications or marketing from us, you may provide us with information such as your name, phone number, email address, company and title/role. We may also collect information concerning your preferences for receiving our marketing communications, and details about your engagement with marketing communications that we send to you.

Automatic data collection. We and our service providers may automatically log information about you, your computer or mobile device, and your interaction over time with our website and the Services, such as:

  • Device data, such as your computer’s or mobile device’s operating system type and version, manufacturer and model, browser type and version, screen resolution, device type (e.g., phone, tablet), IP address, unique identifiers (including identifiers used for advertising purposes), language settings, mobile device carrier, and general location information such as city, state or geographic area.
  • Online activity data, such as pages or screens you viewed, how long you spent on a page or screen, the website you visited before browsing to the website, navigation paths between pages or screens, information about your activity on a page or screen (including button clicks, hovering over elements, typing into input fields), access times, and duration of access, and whether you have opened our marketing emails or clicked links within them.

We use the following tools for automatic data collection:

  • Google Analytics, a web analytics service provided by Google LLC (“Google”). Google Analytics uses cookies to help us analyze how users use the website and enhance your experience when you use the website. For more information on how Google uses this information, click here.
  • Local storage technologies handle authentication in a number of our client-side applications. We store a JWT (JSON Web Token), which is an encrypted secret that uniquely identifies a user in the local storage of the browser.
  • HTTP-only cookies are cookies that are not accessible via client-side scripting and are used for user authentication. They are only accessible via server-side. Note that similar to local storage, we will store a JWT in an HTTP-only cookie.
  • Session storage technologies, which is used similar to local storage except only stores data for the duration of a user's session. This helps maintain form values if a user refreshes the page, so they don't lose any progress. Note, when a user closes the tab they are on, the session storage of the browser is automatically cleared.
  • Web beacons, also known as pixel tags or clear GIFs, which are used to demonstrate that a webpage or email was accessed or opened, or that certain content was viewed or clicked.

Information we collect from third party sources. We may also collect personal information from non-profit organizations, service providers, social media platforms, and other third party public sources.
