Privacy Updated September 4, 2026
I can't see your logs.
Nobody can.
No account, no sign-up, and no way for me to read what you log.
I made Gnash to help people use less nicotine, and that's a private thing. So I built it to know as little about you as possible. Here's the whole picture, in plain words.
Straight answers
- Can you see my logs?
- No. There's no account, and the app has no way to send them to me.
- Can anyone learn from Gnash that I use nicotine?
- Not from me. I never have that information, so I can't share it, sell it, or hand it over.
- Can I delete everything?
- Yes. One button in Settings, and it takes the iCloud copy with it.
- Why should I believe this?
- Try Gnash in Airplane Mode: logging, the timer, the Moodballs, all of it works. And Gnash's page on the App Store carries a privacy label that says the same as this page.
The details
It keeps what you log. Nothing about who you are.
Your breaks, when they started and ended, how they felt, the notes you write, and the plan you set. A few settings, like your theme. Nothing about who you are: Gnash never asks for your name or email, and there is nothing to sign up for.
It lives on your phone, and in your iCloud.
On your phone, and in your own iCloud, so your logs follow you to a new phone. The iCloud copy sits in your private storage, encrypted by Apple, in a space I have no way into. There is no Gnash server with your logs on it.
You can turn iCloud sync off in Settings. Then everything stays on the phone.
Three things leave your phone. Only these.
-
The Lock Screen timerThe moment your break ends, so the screen flips on time.
When a break starts, the app tells a tiny server I run when the break will reach its goal, plus a one-off key iOS gives it for that timer. At the goal, the server asks Apple to refresh your Lock Screen, then forgets what it had. The key can't be traced to you or your logs. Offline when the break starts? Nothing is sent, and the Lock Screen catches up on its own.
-
Feedback you sendYour message, and your email only if you add it.
Your message and the app version go to a service that forwards them to my inbox. Nothing else is attached.

Gnash ProA purchase, handled by Apple.
Apple handles the purchase, like any other. The app learns you're Pro. I never see your payment details.
Nothing else from the app. No analytics, no ads, no trackers, nothing sold or shared.
Apple separately shows me anonymous numbers, like download counts, and crash reports from people who chose to share them in their iPhone settings. That's Apple's collection, under Apple's policy, and I can't switch it off.
One button deletes everything.
Settings has a button that wipes everything: your logs, your plan, and your settings. With sync on, the deletion reaches your iCloud copy too. Export first if you want to keep a copy.
If you turned sync off at some point, an older copy may still be in your iCloud. You can remove it yourself: Settings, your name at the top, iCloud, Manage Storage, Gnash. Apple's guide walks through it.
A few other things.
Motion
The Moodballs roll when you tilt or shake your phone. That uses the motion sensor in the moment, on the phone. Nothing is recorded.
Age
Gnash is for adults who use nicotine and want less of it. It's rated 17+ because it talks about smoking, vaping and snus, not because of anything it collects.
If any of this changes
The date at the top changes, and the app tells you in What's New.
Questions
Email hello@gnash.app. I read every one.
For the curious: the feedback service is Formspree, the timer server runs on Cloudflare, and the iCloud storage is Apple's CloudKit.
