Vapexit privacy policy

Last updated 31 July 2026

Vapexit is made by Serhii Alpieiev. This page describes what the iPhone app stores, who else touches it, and how to get it back or destroy it. It covers Vapexit only — Unbottle, the quit-drinking app from the same developer, is a separate app with its own storage, its own fields and its own policy, published on its own site.

The short version

What is stored

What you enter and log

Kept under your anonymous ID in Google Firestore:

All of it is health information about substance use, and it is treated as such: the storage is scoped to your anonymous ID, and the security rules deny any other signed-in user access to it.

What the app measures about itself

Usage events go to Amplitude and to Google Analytics for Firebase — which screens you open, which onboarding pages you complete, that a puff was logged, that a craving tool ran, whether a paywall was shown or dismissed. Some carry values from your history: a check-in sends the mood and craving ratings; onboarding sends your substance, product mode, goal, the band your dependence score fell in and how many reasons you wrote — never the reasons themselves and never the raw score.

Crashes

Firebase Crashlytics receives crash traces, your device model and iOS version, tied to the anonymous ID, so a crash can be fixed.

Purchases

Subscription state is handled by RevenueCat on top of Apple's own receipt. Apple takes the payment; card numbers never reach the app or the developer.

They act as processors on the developer's behalf and are not permitted to use your data for their own purposes. Data is stored on Google's and these providers' servers, which may be outside your own country.

Your data, in your hands

Settings → Data → Export my data writes your profile, every day and every logged event to JSON or CSV and hands the file to you. It is free, unlimited and covers your whole history, not a recent window — it is a complete copy, produced instantly, without asking anyone.

Settings → Data → Delete all my data destroys your profile, your days and your events. It cannot be undone, so export first if you want a copy. Your anonymous ID and your purchase record survive, so a subscription you paid for keeps working.

Deleting the app from your iPhone does not delete the stored copy, and reinstalling starts a new anonymous ID rather than reconnecting to the old one — so the old records become unreachable rather than deleted. Use Delete all my data first, or email support@vapexit.mriy.io and we will do it.

Because there is no account, a request by email cannot be matched to a particular person's records — which is a privacy feature, not an obstacle: the export and delete buttons in the app do the same job immediately, from the one device that can prove it is yours.

Children

Vapexit is not intended for anyone under 17, and it is rated accordingly on the App Store. It is not knowingly used to collect information from children.

Changes

If what the app collects changes, this page changes with it and the date at the top moves. A change that materially affects what is stored will be described here rather than quietly folded in.
