Privacy policy
Policy revision: 2026-10-14
Scope
This policy describes Ferrofluid Clock, its support website, and messages you voluntarily send to its developer. The clock does not require an account.
Local settings
Theme, color, language, time display and operating-mode preferences are stored locally on your device. Touch input controls the liquid animation locally. Deleting the app normally removes its local preferences; device backups are governed by your system settings.
This website
Our pages do not add advertising, analytics scripts, cookies or forms. The marketing pages load fonts from Google Fonts, which may receive technical request data such as your IP address and browser information. Hosting infrastructure may process IP address, browser information and request time to deliver and secure the website. That is separate from the app’s local clock operation.
Support correspondence
If you email us, we receive your email address and the message or attachments you choose to send. These are used to respond to your support or privacy request. Please do not send passwords or unnecessary sensitive information.
Retention and changes
Local preferences remain until reset or removed. Support correspondence is kept only as necessary to handle the request or meet applicable obligations. You may request deletion of correspondence through the contact below, subject to those obligations. Changes to this policy will appear on this page with an updated revision. Significant data-handling changes require a corresponding policy update.
