Summary
Nixo is an app that helps you quit nicotine (vapes, pouches, e-cigarettes) through progressive steps. What you enter is stored on your device only. Nixo uses no account, no password and no server of ours. The app also uses an anonymous usage analytics tool (PostHog), described below.
1. Who we are
Nixo is an iOS app published by an independent developer, Alexandre Paul. Contact: alexandre-paul@outlook.com.
2. Data you enter
You enter your daily intakes, your steps, your profile (product, price, starting pace) and the cravings you log.
This data stays on your device. It is not sent to any server, neither ours (we have none) nor a third party's. We never have access to it.
No account is required. We do not ask for your name, email address or phone number.
3. Location
Nixo does not request your location and accesses no location data.
4. Notifications
The app can send you reminders. These are local notifications, scheduled and shown by your device. No remote push is used, so no notification identifier is sent to any server. You can decline them at install time or turn them off later in iOS Settings.
5. Anonymous usage analytics (PostHog)
Nixo uses PostHog (EU hosting, eu.posthog.com) to understand how the app is used and improve it. The events sent are usage events: app opened, onboarding finished, subscription screen shown, purchase made.
What is never sent: the content you enter. The data described in section 2 does not leave your device and is not shared with PostHog.
These events are tied to a random technical identifier, specific to the installation, which cannot identify you and is not linked to any account. Legal basis: legitimate interest in improving the product (GDPR article 6(1)(f)). For any request about this data, write to alexandre-paul@outlook.com.
6. Purchases
Nixo offers an auto renewable subscription (monthly or yearly), with a free trial clearly shown before any commitment.
Payments are handled entirely by Apple. We neither see nor store your payment details. Apple only tells us whether the purchase is active.
7. Retention and deletion
Your data stays as long as you keep it. Deleting an item in the app deletes it for good. Uninstalling the app erases all local data.
8. Children
Nixo is not intended for children under 13 and knowingly collects no data about them.
9. Your rights
Because your content lives on your device, you keep direct control over it at all times (view, edit, delete). For the anonymous usage events described above, you can exercise your rights of access, rectification, erasure and objection by writing to alexandre-paul@outlook.com.
10. Changes
This policy may change. The last updated date at the top of this page applies.
