Cookie Policy

1. What Are Cookies & Local Web Storage?

A cookie is a compact alphanumeric data file composed of text characters that a web server transmits to your client web browser (such as Google Chrome, Mozilla Firefox, Apple Safari, or Microsoft Edge) when you load a digital page. Your browser stores this file locally on your device’s storage drive and returns it in HTTP request headers during subsequent visits to that website.

Cookies are classified by lifespan:

Session Cookies: Transient files held solely in your device’s volatile memory during an active browsing session. They are automatically destroyed the moment you close your web browser software.
Persistent Cookies: Stored on your hard drive across multiple browsing sessions, remaining active until their defined calendar expiration date arrives or until you manually clear them through browser settings.

In addition to traditional cookies, modern browsers support HTML5 LocalStorage and SessionStorage. These client-side repositories permit web applications to save data locally within your browser sandbox without continuously transmitting the payload over every HTTP network packet.

2. Why We Utilize Cookies on TempMail Asia

TempMail asia does not require passwords, credit cards, or account profiles. Because we operate without permanent database accounts, cookies serve as our primary mechanism to provide a seamless user experience. Specifically, cookies allow our servers to:

Remember which temporary disposable address you are currently utilizing so that an accidental browser reload does not immediately erase your active inbox.
Defend interactive web forms (such as contact messages) against cross-site request forgery (CSRF) exploits.
Measure overall aggregate site traffic velocity, popular technical articles, and regional device compatibility through privacy-focused analytics.
Permit authorized advertising partners, including Google AdSense, to display non-intrusive advertisements that fund our continuous high-throughput server costs.

3. Four Core Categories of Cookies Employed

The cookies and local storage tokens deployed across TempMail asia fall into four functional categories:

Category 1: Strictly Necessary

These cookies are essential for the fundamental operation of our disposable email web application. Without them, the site cannot preserve your active temporary email address across page reloads or protect form endpoints from cross-site request forgery. They do not store personally identifiable data.

Category 2: Functional & Preferences

These cookies preserve your interface customization choices, such as dark/light UI color schemes, sound alert toggles when new emails arrive, or language preferences. They enhance usability without tracking your activity across third-party websites.

Category 3: Analytics & Performance

We utilize Google Analytics 4 with IP anonymization enabled. These cookies collect aggregated, anonymous telemetry—such as pages visited, bounce rates, and browser screen dimensions—enabling us to optimize server performance and editorial content.

Category 4: Advertising & Targeting

Placed by Google AdSense and certified programmatic ad exchanges, these cookies track browsing habits across the internet to serve contextual or personalized advertisements and prevent ad fatigue through frequency capping.

4. Google AdSense & DoubleClick DART Cookies

Google is an authorized third-party vendor on TempMail asia. Google utilizes cookies, including the DoubleClick DART cookie, to serve advertisements to visitors based on their visit to our site and other locations across the internet.

Key Information Regarding Google AdSense Cookies:

Behavioral & Contextual Targeting: The DART cookie allows Google and its partner advertising networks to serve advertisements based upon browsing history, topic relevance, and geographic region.
Non-Personal Telemetry: DART cookies track interaction metrics, browser configuration, and ad views; they DO NOT record personal identifiers such as your legal name, physical address, credit card numbers, or telephone details.
Ad Personalization Opt-Out: You may opt out of personalized Google advertising at any time by configuring your preferences at https://adssettings.google.com/.
Third-Party Vendor Disclosures: For comprehensive details on how Google handles data collected across partner websites, please consult https://policies.google.com/technologies/partner-sites.

6. Third-Party Ad Vendors & Programmatic Networks

Third-party advertising partners and demand-side platforms participating in Google’s certified ad exchange may also place cookies, web beacons, or tracking pixels on your device when an ad unit renders on our pages. These technologies help ad vendors determine how often an advertisement is displayed, measure click-through rates, and detect fraudulent automated bot traffic.

We do not control the lifespan or specific scripts deployed by third-party ad networks once executed in your browser sandbox. We encourage you to review the privacy and cookie policies of individual ad networks to understand their data governance practices.

7. How to Manage & Block Cookies in Browsers

Every modern web browser provides comprehensive controls permitting you to view, manage, restrict, or purge stored cookies and local storage tokens. Below are instructions for popular browsers:

Navigate to Settings > Privacy and Security > Third-party cookies. From here, you can choose to "Block third-party cookies", clear existing cookies, or configure site-specific permissions.

Open Settings > Privacy & Security. Under Enhanced Tracking Protection, select "Strict" or configure "Custom" to block cross-site cookies, cryptominers, and tracking cookies.

On macOS, go to Safari > Preferences > Privacy and enable "Prevent cross-site tracking" and "Block all cookies". On iPhone/iPad, open Settings > Safari and toggle "Prevent Cross-Site Tracking".

Navigate to Settings > Cookies and site permissions > Manage and delete cookies and site data. Toggle "Block third-party cookies" to prevent cross-site advertising trackers.

9. Impact of Disabling Cookies on Site Functions

While you maintain the complete right to block or delete cookies, please be aware of the following technical consequences on TempMail asia:

Mailbox Reset on Page Refresh: If you disable first-party cookies, our application will not be able to store your generated mailbox handle (tm_active_email). Consequently, if you reload the page or navigate away, a new random email address will be created, and your previous temporary inbox will become inaccessible.
Form Validation Failures: Disabling session cookies may interfere with CSRF security tokens required to submit contact messages or feedback forms.
Non-Personalized Ads: Blocking third-party advertising cookies does not eliminate advertisements; instead, you will continue to see generic, non-personalized contextual ads.

10. Web Beacons & Tracking Pixel Neutralization

Many third-party marketing services, newsletters, and verification senders embed transparent 1x1 GIF tracking pixels inside HTML emails to track when, where, and on what device you read incoming messages.

As part of our commitment to digital privacy defense, TempMail asia operates an automated email sanitization pipeline that intercepts and disarms external tracking beacons, strips remote tracking parameters, and cleans inline stylesheets before rendering received emails in your browser. This prevents third-party senders from tracking your browser environment through correspondence delivered to our service.

11. Do Not Track (DNT) & GPC Signals

Some browsers transmit "Do Not Track" (DNT) signals to websites. Because there is currently no universal industry standard for DNT signal compliance, TempMail asia does not alter its automated processing behavior upon detecting a DNT header.

However, we actively respect the Global Privacy Control (GPC) standard. When your browser transmits a verified GPC header, our third-party advertising tags are instructed to restrict data sharing for cross-context behavioral advertising pursuant to California and European privacy regulations.
