Poff! is a breathing timer for everyday relaxation and general wellness, made by Zwizzly AS and available at poff.app and as an iPhone and Android app. There is no account, no sign‑up, and every breathing session works fully offline. This page explains how preferences and optional tips are handled.
What we don't collect
The app has no crash‑reporting SDK or advertising SDK. We don't track your breathing sessions. Your chosen mode, duration, visualizer, and custom pattern are stored only on your own device.
Optional tips
Every feature of Poff! is free. If you choose to leave an optional tip, it unlocks nothing — it's just a thank‑you. Tips are handled entirely by the platform you're on, and we never see or store your card details:
- iPhone and Android: tips are processed by RevenueCat and by Apple's App Store or Google Play, using an anonymous, random purchaser ID that Poff! does not link to your name or email. RevenueCat initializes when you open the Support sheet and processes purchase history for tip functionality and purchase analytics. It does not receive your breathing-session history.
- Web: tips are handled by a Stripe Payment Link, which takes you to a page hosted by Stripe. We don't receive your card details, and we don't run our own checkout or server for this.
Apple, Google, RevenueCat and Stripe each process purchase history for fraud prevention and their own legal and accounting requirements, under their own privacy policies.
Security, retention and deletion
Purchase data is transmitted using HTTPS encryption. We do not operate an account or breathing-session database. Preferences remain in your device's app or browser storage until you clear that storage; any device backups are controlled by your device's backup settings.
Purchase records are retained by the purchase providers to operate the tip service, handle purchase support, prevent fraud, and meet their legal and accounting obligations. Their privacy policies govern their own retention and deletion requirements.
For questions or requests about retention or deletion of data handled for Poff!, email eddie.holt@zwizzly.com. Because purchases use an anonymous identifier, a store order reference may be needed to identify a relevant record. Do not send card details. Deleting app storage does not delete purchase records held by Apple, Google, RevenueCat or Stripe; records that a provider must retain for legal obligations remain subject to that provider's policy.
Device data
Poff! doesn't collect or store any health data, and it doesn't connect to Health app / Health Connect at this time.
