We built it so we can't see your data.

Flo settled with the FTC in 2021 for sharing period and pregnancy data with Facebook and Google without user consent. A $56M class action followed in 2025. We built an app where data sharing is architecturally impossible — not just against our policy.

No account required
Open the app and start tracking. No email, no password, ever.
No data transmitted
Nothing leaves your phone. The app has no network calls for your data.
No analytics or crash reporting
We included no SDKs that phone home. Zero.
No third-party SDKs
No Firebase, no Sentry, no Amplitude. Nothing.
Deletion is permanent
Delete the app, your data is gone. No cloud copy to worry about.

Everything you need. Nothing you don't.

Three core features. No subscriptions. No upsells. Just a well-made tool that does one thing well.

Cycle calendar

Colour-coded period days, fertile window, and predicted next period. Updates automatically as you log. Navigate back through months to review your history.

Daily log

Log flow, symptoms, pain level, mood, and notes. Opens in one tap. Auto-saves when you close — no "save" button required.

Insights

Average cycle length, period length, regularity score, and symptom frequency. All calculated from your local data — no AI, no server.

Common questions

Is my data really private?

Yes. Vela has no server, no account system, and makes no network calls for your data. We cannot access your data because it never leaves your phone. This is verified by the app's architecture, not just our privacy policy.

What happens if I lose my phone or get a new one?

In v1.0, your data is tied to your device. If you have iCloud backup enabled and Vela is included, it will restore. If not, the data is lost. Encrypted optional backup is on our roadmap for v1.1.

Does it work without internet?

Completely. Vela works with no internet connection, ever.

What if I want to delete my data?

Delete the app. Your data is deleted with it. There is no cloud copy, nothing to contact us about.

Is there a free trial?

No. We believe you should pay once or not at all. Apple's and Google's standard refund policies apply if the app doesn't work for you.
