Caffeine · Last updated August 2026
Caffeine collects no data at all. Everything you enter stays on your device. There are no accounts, no analytics, no trackers, and nothing is sent to us or anyone else.
The drinks you log and your settings (how fast you clear caffeine, your sleep threshold, bedtime, appearance, and your saved drinks) are saved locally on your device so the app works and remembers your history. This information never leaves your device and is not accessible to us.
None. We do not collect, transmit, sell, or share any personal information. The app makes no network requests and contains no outside analytics or advertising code.
You can export your logged history as a CSV file at any time from Settings. Once you export or share that file, it is under your control.
Because everything is stored on your device, deleting the app removes all of its data.
The app collects no data from anyone, including children.
If this policy ever changes, the updated version will be posted on this page with a new date.
