Quit vaping, one roast at a time
Every puff gets a reaction.
Puffkin is a grumpy little cloud who lives in your lungs. Log every puff, watch your daily limit shrink to zero, and get roasted the whole way. He roasts the habit, never you.

Support & FAQ
How it works
Count it. Shrink it. Quit it.
No account, no tracking. Your puffs stay on your phone.
See the damage. Then beat it.
Every day against its limit, your best day, your streak, and the money you’ve kept.
Roasts worth posting
Puffkin reacts to every puff. When he lands a good one, turn it into a story card in one tap.

Contact support
A real human reads every email.
puffkin@evtsoy.comWe usually reply within 2 business days.
- Your phone model and iOS / Android version
- The Puffkin version (You → bottom of the screen)
- What happened, and a screenshot if you have one
Please don't send payment card numbers. We never need them.
How do I cancel my subscription?
Subscriptions are billed by Apple or Google, so you cancel them there. Deleting the app does not cancel it.
- iPhone: Settings → your name → Subscriptions → Puffkin → Cancel Subscription. Apple's guide
- Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → Puffkin → Cancel. Google's guide
Cancel at least 24 hours before the trial or billing period ends to avoid the next charge. You keep access until the period ends.
Can I get a refund?
Refunds are handled by the store you paid through, under their rules. We can't issue them ourselves.
- Apple: Request a refund from Apple (reportaproblem.apple.com).
- Google Play: Google Play refund policies.
I paid but Puffkin is still locked
Open the paywall and tap Restore, or go to You → Restore purchases. Make sure you're signed in with the same Apple ID or Google account you paid with. Still stuck? Email us with the date of purchase. A screenshot of the store receipt helps, minus any card details.
I got a new phone. Where did my history go?
Puffkin has no account, and your puffs are stored only on your phone. They move to a new phone only through your device backup (iCloud, Google, or a computer backup), depending on your backup settings. Your subscription isn't tied to your data: tap Restore purchases on the new phone.
How do I delete my data?
In the app: You → Start over → Delete all my data. That erases your puffs, stats, plan and settings from your phone. Deleting the app also removes them. Device backups you made earlier may still contain a copy until they're replaced or deleted.
To delete emails you've sent us, write to puffkin@evtsoy.com. See the Privacy Policy for details.
Reminders aren't arriving
Check that notifications are allowed for Puffkin in your phone's settings, and that Focus or Do Not Disturb isn't hiding them. Then check You → Reminders. Reminders are scheduled on your phone, so a low-power or battery-saver mode can delay them.
The roasts are too much today
Turn on a go-easy day (Home or Plan) and Puffkin stops roasting until midnight. Or change his roast level to Mild in You → Puffkin. He roasts the habit, never you. If a line ever crosses that line, email us the text and we'll fix it.
Is Puffkin medical advice?
No. Puffkin is a tracking and motivation tool, not a medical device or treatment. Nicotine withdrawal can be hard. Talk to a doctor or pharmacist, especially if you're pregnant, have a health condition, or are thinking about nicotine replacement.
Free help: in the US, call 1-800-QUIT-NOW or see the CDC's quitting guide. In the UK, NHS Quit Smoking. Elsewhere, your doctor or local health service. In an emergency, call your local emergency number.
Puffkin is for adults (18+, or the legal age to buy nicotine where you live). It's a tracking and motivation tool, not medical advice, diagnosis or treatment. Talk to a doctor or a quitline for support.
