# 1. What Are Cookies & Local Storage?
Cookies are small text files placed on your device (computer, tablet, or mobile phone) when you visit websites. They are widely used to enable websites to function properly, enhance security, and remember user preferences across sessions.
Local Storage is a modern web standard that allows web applications to store key-value data directly inside your browser. Unlike traditional cookies, data stored in Local Storage remains entirely on your device and is not automatically transmitted to servers with every network request.
# 2. How We Use Cookies & Storage Technologies
At Percent Off Calculator, privacy is built into our core architecture. We do not use invasive tracking, behavioral profiling, or cross-site advertising trackers. We use storage technologies strictly for:
- Saving your cookie consent choice so you are not prompted repeatedly on return visits.
- Preserving your language and interface settings for a seamless browsing experience.
- Monitoring anonymized technical metrics (such as page loading speed and CDN availability) to maintain high reliability.
# 3. Types of Cookies We Use

4. 100% Client-Side Calculation Guarantee
All discount calculations, price inputs, sales tax values, and percentage formulas execute exclusively inside your web browser's JavaScript runtime memory. No calculation inputs or personal financial figures are ever logged, sent, or stored on our servers.
# 5. How to Control and Manage Cookies
You have the right to accept, refuse, or remove cookies at any time through your browser settings. You can configure your browser to reject all cookies, notify you when a cookie is placed, or delete stored browsing data.
If you choose to disable cookies or clear Local Storage, your consent preference will be reset on your next visit, but all discount calculators will continue to function with full accuracy.
