1 What Are Cookies and Local Storage?
Cookies are small text data files placed on your computer, tablet, or smartphone when you visit web pages. They are widely utilized by websites to ensure standard operation, improve user efficiency, and store client preferences.
In addition to standard HTTP cookies, modern web applications utilize HTML5 Local Storage. Local Storage allows web applications to store information directly inside your browser without sending that data to remote servers on every network request.
2 How Time Addition Calculator Uses Cookies
At Time Addition Calculator, our core philosophy is privacy by architecture. Our sexagesimal arithmetic engines, time addition, and subtraction calculations execute 100% locally within your device's browser memory (client-side JavaScript).
We do not use tracking cookies to build advertising profiles, do not participate in cross-site tracking networks, and never sell personal information to third parties. We use cookies and local storage strictly to:
- Remember your cookie consent status so you are not repeatedly prompted on return visits.
- Preserve user interface preferences such as time display mode (HH:MM vs. HH:MM:SS) and active calculation rows.
- Ensure stable performance, fast asset delivery, and defense against malicious automated bot traffic.
3 Cookies & Storage Elements in Use
The table below outlines the specific storage items utilized on our website:
| Identifier | Type | Lifespan | Category | Purpose |
|---|---|---|---|---|
| tac_cookie_consent | Local Storage | Persistent | Essential | Remembers when a user has accepted the Cookie Consent banner to prevent recurring popups. |
| tac_time_format | Local Storage | Persistent | Functional | Preserves your preferred calculator format (e.g. HH:MM vs. HH:MM:SS) between browser sessions. |
| tac_calc_state | Session Memory | Session | Essential | Retains calculation rows in browser memory while the tab is active; never transmitted to our servers. |
4 How to Manage and Disable Cookies
You have full control over cookies and local storage. Most web browsers allow you to manage your cookie preferences through their configuration settings. You can instruct your browser to delete existing cookies, block new cookies, or alert you when cookies are set.
Instructions for managing cookies in common browsers:
- Google Chrome: Settings → Privacy and security → Cookies and other site data.
- Mozilla Firefox: Settings → Privacy & Security → Enhanced Tracking Protection & Cookies.
- Apple Safari: Preferences → Privacy → Manage Website Data.
- Microsoft Edge: Settings → Cookies and site permissions → Manage and delete cookies.
Note: Disabling local storage or cookies may reset your calculator interface preferences on each visit, but will not prevent you from using the calculation tools.
5 International Privacy Compliance (GDPR, ePrivacy, CCPA)
Our cookie implementation complies with the European Union General Data Protection Regulation (GDPR), the ePrivacy Directive (EU Cookie Law), and the California Consumer Privacy Act (CCPA). Because our service requires no user registration and conducts all calculations client-side without storing user telemetry, we adhere strictly to global data minimization principles.
6 Updates to This Cookies Policy
We may update this policy periodically to reflect changes in our technology, regulatory standards, or operational procedures. Any revisions will be reflected on this page with an updated "Last Updated" date.
