Privacy Policy

Puffdown · Effective November 12, 2026

Puffdown (“the app”) is built by Bohdan Kirov, an independent developer based in Ukraine, publishing as Solution Apps (“we”). This policy explains what data the app handles and why. Short version: your quitting data stays on your phone, we have no accounts, no ads and no tracking.

1. Data that stays on your device

Everything you enter — your plan (gradual or cold turkey), puffs per day, spending, nicotine strength, reasons for quitting, puff log, cravings, triggers and reminder settings — is stored locally on your device. It is not sent to us or to anyone else. We cannot see it, and we cannot recover it if you delete the app.

2. Purchases

Subscriptions and one-time purchases are processed by Apple. We never receive your name, email or payment details. To check whether you have Puffdown Plus, the app uses RevenueCat, which receives an anonymous app user ID, your purchase history for this app, and basic technical data (device model, OS version, app version, country/storefront, IP address). This is used only to unlock features, restore purchases and give us aggregate revenue statistics.

3. App updates

The app may download small updates from Expo’s update service (Expo privacy policy). The request contains technical data such as app version, platform and IP address, and no personal content.

4. Notifications

Reminders and milestone notifications are scheduled locally on your device. We do not use push servers and do not collect a push token.

5. What we don’t do

• No sign-up or account.
• No advertising, no ad SDKs.
• No analytics or tracking across apps or websites.
• We don’t sell or share personal data.
• We don’t access your Health app, contacts, photos or location.

6. Email

If you email us, we use your email address and message only to reply, and delete the conversation when it is no longer needed.

7. Your rights

Because we don’t hold your in-app data, you control it directly: use Settings → Start over or delete the app to erase it. For purchase data held by RevenueCat, or any other privacy request (access, deletion, objection — including under GDPR and CCPA), email privacy@solutionapps.app. We respond within 30 days.

8. Children

Puffdown is intended for adults (17+) and is not directed to children. We do not knowingly collect data from children.

9. Changes

If this policy changes, we will update this page and the effective date above.
