Questions

Can't find what you need? Write to us.

Is Nücum free?

Yes. The core is always free and has no ads. Sync between phone and Windows is free too. Coach, deep insights, unlimited plans, Smart Day and photos, video and voice in the journal open with Plus; Pro also opens the space scenes of focus mode (Cosmic, Orbit, Night sky, Northern lights, Moon phase). Both are one-time purchases. You can try Pro for 7 days without a card; nothing is charged when it ends and your data stays.

Which devices does it run on?

Android phones and Windows 10 or 11 (64-bit) computers. The Chrome extension is coming soon. There is no iPhone or Mac version for now.

How does sync between phone and computer work?

Your phone and Windows use the same Nücum account, for free: on every device where you sign in, your routines, focus records and journal are the same. Changes you make without internet are sent when the connection is back.

Where is my data stored?

The servers and the database are in Frankfurt, Germany. The connection between the app and the server is encrypted (HTTPS). We never use your content for ads, profiling or training AI models. Details are in the privacy policy.

Can I export my data?

Yes, all of it. Settings → Data → Export, as JSON, CSV or Excel.

How do I delete my account?

On the desktop: Settings → Connections and data → My account → Delete account; on the phone: Settings → Sync → Delete account. Without the app, use the account deletion page. Your content is permanently deleted within 30 days.

Can I get a refund?

Purchases are made through Google Play; payment and refunds follow Google Play's rules. Use Google Play's refund page first; if that does not solve it, write to us.

Why does Windows show a warning when I install?

Windows can show a SmartScreen warning for new apps that few people have downloaded yet. Choose More info → Run anyway to install. Rather not see a warning? Get it from the Microsoft Store.

What can the Chrome extension access?

Only what the focus screens need: focus sessions, the routine and activity list, its own look settings and a quick note. It has no access to your browsing history, open tabs or the sites you visit; it does not collect or send them.
