Learn More About TrueAppend

TrueAppend was created to save you time and money by reducing overhead and the costs associated with data appends.

Our data append service helps you enhance your constituents, donors, alumni, or patients using the most up-to-date data available in the industry.

We don't believe in charging according to traditional pricing models, which often require a high minimum number of records and include additional fees to export your data. Instead, TrueAppend provides the same exact service as any other provider at a fraction of the cost.

Our team of technologists, product managers, and client services personnel are here to help, and we aim to deliver simple, clean, and effective solutions.  From our first release to our current, we are constantly improving the product to help you get the most out of our services.

TrueAppend takes your privacy and data security seriously.

TrueAppend respects the privacy of everyone in our data universe.

All data uploaded to TrueAppend through https://app.trueappend.com is secured using 256-bit HTTPS TLS encryption, the same level as online banking. Uploaded data is physically separated, never commingled, and stored on an encrypted file system. The append process uses merged keys encrypted with a one-way, session-level, private hash that cannot be decrypted by any other users, process, or session. Once the append data is returned, all input is destroyed and your output keys are retained until you delete the file. We retain output keys to provide the update service so you can automatically receive notifications without having to re-process your file.
