Privacy Policy
Updated October 27, 2026, before the app launch
Your weather belongs to you. Nimbu collects no data. No account, no ads, no in-app analytics, no tracking across apps. Nimbu has no server.
What stays on your iPhone
| Data | Why | Where |
|---|---|---|
| Emotions you name, date, exercises done, your Nimb's stage | Keep your notebook and your Nimb alive | Your iPhone |
| Sleep, heart rate and heart rate variability, steps, read from Health with your consent | Compute your fatigue forecast | Computed on your iPhone, never copied elsewhere |
| Subscription status | Unlock paid content | Your Apple account |
Health data
Nimbu reads Health data only if you allow it, one data type at a time. This data never leaves your iPhone, is never used for advertising and is never sold or shared. You can turn off access in Settings, Health, Data Access & Devices.
Payments
Apple will collect subscription payments. Nimbu will never see your card details or your identity.
Deleting your data
Deleting the app erases your notebook from the iPhone. Your Health data stays in the Health app, under your control.
If you write to us
When you write to [email protected], we keep your message and address to answer you, and for three years at most after our last exchange. You can ask to access, correct or delete them at the same address. You may also contact the French data protection authority (cnil.fr).
Waiting list
If you ask to be notified at launch, we keep your email address in a Brevo list (Sendinblue SAS, France) to write to you on launch day. We delete it on request, and at the latest six months after launch. Legal basis: your consent.
Minimum age
Nimbu is meant for adults.
