Euki App Cost: Is Free Really Free for Privacy?
TLDR
Euki is free, privacy-first, and stores data on your device — the same architectural approach as Floriva. The tradeoff is no cross-device sync, no iOS-Android parity beyond basics, and dependency on nonprofit grant funding with no guaranteed long-term roadmap. Floriva costs $2.99/mo and adds sync.

Hidden Costs You Won't See on the Pricing Page
- ⚠ No revenue model: Euki is nonprofit-funded, meaning features and maintenance depend on grant cycles, not sustainable recurring revenue
- ⚠ No cross-device sync: if you switch phones or lose your device, all historical data is gone
- ⚠ Available on iOS and Android but feature parity is not always maintained across platforms
- ⚠ No web access — phone-only
- ⚠ Limited prediction algorithm depth compared to apps with millions of training data points
Euki Is Genuinely Free and Genuinely Private
Euki does what few free apps manage: it charges nothing and still does not monetize user data. There is no ad tier, no data licensing, and no paid upgrade. It is funded by reproductive health nonprofits, uses on-device storage, and requires no account.
For users who need a free period tracker with real privacy guarantees, Euki is the most credible option in the market. We are not going to tell you Euki is bad — it is not.
The Funding Model Question
Euki’s strength is also its structural limitation. Nonprofit funding means Euki’s development timeline is driven by grant cycles, not user demand. When a grant ends, development can slow or stop. The app could fall behind on iOS and Android OS compatibility. Features that paying users would fund — like cross-device sync — are not priorities in a grant-funded model.
This is not a knock on Euki’s mission. It is a description of how nonprofit software projects work under resource constraints.
Several well-intentioned reproductive health apps have gone stale or inactive when nonprofit funding shifted. Users who built their tracking history in those apps lost continuity.
What $2.99/mo Adds
Floriva uses the same architectural privacy approach as Euki: data stays on your device, no account required, nothing on a server to subpoena. The $2.99/mo subscription funds:
- Encrypted cross-device sync (your data, readable only on your devices)
- Active iOS and Android development
- Long-term product continuity
If $0 is the constraint, Euki is a solid choice. If $2.99/mo is manageable, Floriva adds sync and a sustainable product roadmap.

Is Euki actually private?
Yes. Euki stores data on your device with no server-side storage. No account is required. The International Planned Parenthood Federation and other reproductive health nonprofits fund it specifically because of the privacy architecture. The data never leaves your phone.
What is the risk of using a free nonprofit app for period tracking?
The risk is continuity, not privacy. Nonprofit apps depend on grants. If funding is not renewed, development stops. Unlike a subscription-funded product, there is no direct revenue signal to prioritize feature work or maintain the app through OS updates. This is not a theoretical risk — several reproductive health apps have gone inactive when funding ended.
How does Floriva differ from Euki?
Both store data on-device and require no account. Floriva adds encrypted cross-device sync and is funded by subscriptions rather than grants, which provides a more direct incentive to maintain and improve the product. Floriva costs $2.99/mo.
Tired of paying for an app that sells your data?
