> Euki is the only app Mozilla recommends without reservations. "Euki is special," Wodinsky* says.

> Unlike the other apps on this list, Mozilla says Euki keeps all your health information stored on your device, without even sending it to the company's servers.

> You don't even need to make an account, so you can stay completely anonymous. Euki also offers a "decoy" feature that shows fake, harmless information if someone gets your phone and tries to snoop.

It's not mentioned in the article.

Like Euki it's local-only. I don't know how they compare as far as features but it's cool that there are two good apps out there.

Although the article doesn't accuse us of doing anything improper, we weren't contacted for comment, so I'd like to clarify our role.

We are customer data infrastructure, not a data broker. We do not buy, sell or monetize the customer data that passes through our systems.

Our role is analogous to infrastructure: customers choose what data to send, and RudderStack routes that data to the destinations they configure (analytics tools, data warehouses, marketing platforms, etc.). The customer owns the data and decides where it goes; RudderStack does not repurpose it for its own business.

Infrastructure providers like us should be held to high standards for security and privacy, but we should not be confused with companies that collect or monetize end-user data.

The one downside is that they do days since last period as days since the end of your last period, not days since the start, unlike literally every woman and gynecologist ever.
