Privacy
Your drinks are your business.
Last updated 7 October 2026
Caffeine vs Water is built so we never see your data. The app has no account, no ads, no analytics and no tracking. This page explains what the app and this website do with information.
The app
- Drinks and settings are stored on your iPhone, shared with the app's widgets, and synced to your Apple Watch directly. They are not sent to us or to any server.
- Apple Health is optional. If you allow it, the app saves the caffeine and water you log, reads your weight to set your water goal, and reads your sleep to set your bedtime and show caffeine-vs-sleep insights. Health data stays in Apple Health on your devices.
- Location is optional and only used for places in your routine, so arriving at your usual café can count your drink, and for finding cafés nearby. Places are watched on your iPhone, and your location isn't sent to us. Searching for nearby cafés uses Apple Maps, under Apple's privacy policy.
- Notifications are scheduled on your iPhone and Apple Watch.
- Purchases, when available, are handled by Apple. We don't receive your payment details.
Deleting the app deletes its data. Data you allowed into Apple Health stays there until you remove it in the Health app.
This website
- No cookies or tracking. The site doesn't set cookies or use tracking scripts. Fonts and images are served from this domain.
- Visit counts. To see which pages people read, we count visits with Cloudflare Web Analytics. It doesn't use cookies or fingerprinting and doesn't identify you.
- Beta sign-up. If you join the beta, we send your email address to Apple so TestFlight can email you an invite. We don't keep a copy, but as a tester your email shows in App Store Connect, and we may use it to ask for feedback and share updates. Email [email protected] to stop these emails. We note which page the form was on, to learn which pages help people find the app, but not your address. Apple handles it under Apple's privacy policy, and you can leave the beta any time in the TestFlight app.
- Bot check. The sign-up form uses Cloudflare Turnstile to stop automated sign-ups. It checks your browser, not who you are, and sets no tracking cookies.
- Hosting. The site is hosted on Cloudflare, which processes standard request data such as IP addresses to deliver and protect the site.
Children
The app isn't directed at children under 13, and we don't knowingly collect their information.
