privacy policy

Effective September 2, 2026.

what nil stores

nil stores what you give it. From onboarding: the substances you use, the prices you pay, your usage estimates, your quit plan and start date, the reasons you picked for quitting, and your dependency reading, which nil calls gravity. After that: the nicotine purchases you log, slips, pledges, cravings with their tags and any notes you add, and the times you asked to be reminded.

nil keeps all of it on your iPhone, in two places: the app's private storage, and a second area shared with its own widgets and Live Activity so they show the same data as the app. nil never sends any of it to a server.

If iCloud Backup is on, this data is included in your backup like any other app's data. iCloud backups are kept by Apple, and Apple's privacy policy governs them, not this one. A backup you make to your own computer stays on that computer, under your control, until you delete or replace it.

what nil does not do

• There is no account and nothing to sign in to.
• There is no server. nil does not send what you enter anywhere.
• There are no analytics, no advertising, no tracking and no third-party SDKs.
• The developer cannot see your data and does not sell it or share it with anyone.

paying for nil

Subscriptions are sold and billed by Apple through the App Store. nil never receives your payment details. nil asks Apple's StoreKit, on your device, whether your subscription is active. Your Apple Account and the purchase itself are covered by Apple's privacy policy.

notifications

Reminders are scheduled locally, on your device, by iOS. nil has no push server, so nothing leaves your phone to deliver them.

crash reports

If nil crashes, Apple may share a crash report with the developer, but only if you have turned on "Share With App Developers" in iOS Settings, under Privacy & Security, then Analytics & Improvements. Crash reports describe what the code was doing when it failed. They do not contain anything you entered in nil.

deleting your data

Open the profile screen in nil and choose "delete all my data". It removes everything the app stored. Deleting the app itself also removes its data from your iPhone. Copies inside an iCloud backup stay until that backup is replaced or deleted, and Apple manages those. A backup on your own computer is yours to delete.

your rights

Privacy laws give you rights over the data a company holds about you. The developer holds none of what you enter in nil; it is all on your device, under your control, and "delete all my data" on the profile screen is always there. Apart from the crash reports described above, which contain nothing you entered, the only personal data the developer ever receives is an email you choose to send to support. You can ask at the same address to have it deleted.

children

nil is for adults 18 and older. It is not directed at children. Whatever anyone enters, at any age, gets the same treatment: nil never sends it anywhere, so the developer never sees it.

this website

nilquit.com sets no cookies, runs no analytics and loads nothing from third parties. Its font is served from this site. The site is hosted on Cloudflare Pages, and Cloudflare may log IP addresses and similar connection details to run the service and keep it secure. Cloudflare's privacy policy explains what it keeps.

contact

Questions about this policy go to support@nilquit.com. If you email support, your message and your email address are used only to answer you. Mail to that address reaches the developer's inbox through Cloudflare's email routing, so the Cloudflare privacy policy linked above covers that step too. This policy is published by the person who makes nil, TODO(owner): legal name, called "the developer" throughout.

changes

If this policy changes, the new version is posted on this page with a new effective date. Before any future version of nil adds optional accounts or community features, this policy will be updated first, so you can read what changes before anything does.
