What is hashed data?

Hashed data refers to information that has undergone a one-way transformation using a hash function. This process takes something like an email address and turns it into a unique set of characters.

​
How hashing works

  • Consistency — The function always produces the same output for the same input. Each email address generates a distinct hash.
  • Irreversibility — It is impossible to reverse a hash back to the original email address.
We use “salted” hashes, combining the email address with a secret key before hashing. This makes it harder for outsiders to link hashes to emails.

​
How hashed data is used on the platform

When you view the Customer section, you may find a hashed record for an email address. We store hashed records in two cases:
  • When a client launches with us, we import their existing customer list.
  • When someone places an order with one of our clients.
In both cases, we only use the hashed data to indicate that the person has had a relationship with the brand and, as an existing customer, cannot claim a reward. We do not use hashed data for any other purpose.

Hashing vs encryption

  • Hashing — A one-way process that turns data into a unique string. Irreversible. No keys involved.
  • Encryption — A two-way process using a key to transform data. Reversible with the correct key.

​
Key takeaway

We store data in hashed form for security. The original email address cannot be recreated from its hash.
