FAQ

Is Sylvelle free?

Yes — completely free. No in-app purchases, no subscriptions, no paywalls. Donations are welcome but never required.

Do I need to create an account?

No account, no sign-up, no email. The app works fully without one. Your identity stays entirely on your device.

Does it need an internet connection?

No. Sylvelle is offline-first — everything runs locally on your device. The optional AI coach requires an internet connection only when you choose to use it.

Is my data private?

Yes. No analytics, no trackers, no cloud storage. Everything is AES-256 encrypted on your phone, protected by a passphrase you choose.

What if I lose my phone?

Your data is encrypted on-device. Without your passphrase, no one can read it — including us. We recommend keeping a secure backup of your passphrase.

Who is Sylvelle for?

Any woman who wants a structured, private companion for self-improvement — whether that's style, fitness, confidence, mindset, or all four. There's no single "right" starting point.

Is there a version for teens?

Yes. The Teen Edition (ages 13–17) is a separate build with extra safety guardrails: capped coaching intensity, mature content removed, and age-appropriate resources.

Is it Android only?

For now, yes. iOS is the next platform after the Android launch. Join the waitlist to be notified.

What is the optional AI coach?

An on-device-memory AI companion that brings the coaching grid to life in natural conversation. It requires your own API key (from a provider of your choice) and an internet connection. The engine delivers full value without it.

Is the source code open?

Not currently. Sylvelle is closed-source to protect the quality of its content and user experience.
