Your tasks, notes, diary, reminders and settings are stored only in your browser (chrome.storage.local) — never collected or sent anywhere. The one exception is the optional star reading: only if you choose to add your birthday, Peeka sends your birth date, time and city (and the city name you search) to its own server at api.peeka.com.cn, solely to calculate your reading. That data is kept on your device, is never sold, and is never shared with third parties — and it stays off until you add it. Peeka's use of data complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
