Understanding Cookies and Tracking Technologies

This Cookie Policy explains how Perigee Science Wire uses cookies, web beacons, pixels, and similar tracking technologies (collectively, "Cookies") on our website perigeescience.jp and related services. Cookies are small text files placed on your device when you visit our website. They help us recognize your device, remember your preferences, understand how you use our services, and improve your overall experience. This policy should be read in conjunction with our Privacy Policy, which provides additional information about how we collect and use your personal data.

Types of Cookies We Use

We use four main categories of cookies on our platform. Strictly necessary cookies are essential for the basic functionality of our website and cannot be disabled. These cookies enable core features such as security, authentication, session management, content delivery, and load balancing. Without these cookies, services you have requested cannot be provided. Performance and analytics cookies help us understand how visitors interact with our website by collecting information about pages visited, time spent on pages, click patterns, traffic sources, and technical errors. This data is aggregated and anonymized, allowing us to analyze trends, measure site effectiveness, and identify areas for improvement. Functional cookies remember your choices and preferences to provide enhanced, personalized features including language preferences, content recommendations, viewing history, and interface customization. Marketing and advertising cookies track your browsing activity to deliver relevant advertisements and promotional content. These cookies help us measure advertising campaign effectiveness, limit ad frequency, and understand which marketing channels are most effective.

Specific Cookies Used on Our Platform

Essential cookies include session identifiers (session_id) that maintain your login state and are deleted when you close your browser, security tokens (csrf_token) that protect against cross-site request forgery attacks and last for your session, and consent preferences (cookie_consent) that remember your cookie choices for 12 months. Performance cookies include analytics identifiers (_ga, _gat, _gid) provided by Google Analytics that track usage patterns and last for 2 years, performance monitoring (perf_track) that measures page load times and lasts for 24 hours. Functional cookies include user preferences (user_prefs) storing your language and display settings for 12 months, content history (content_viewed) tracking recently viewed articles for 30 days, and recommendation data (rec_data) powering personalized content suggestions for 6 months. Marketing cookies include advertising identifiers (ad_id) used for targeted advertising lasting 90 days, and campaign tracking (utm_source, utm_campaign) measuring marketing effectiveness for 30 days.

Third-Party Cookies

In addition to our own first-party cookies, we allow certain trusted third parties to place cookies on your device. Google Analytics provides web analytics services to help us understand site usage, user demographics, and traffic patterns. Their cookies typically last for 2 years. Payment processors such as Stripe use cookies to facilitate secure payment transactions and prevent fraud during checkout. Social media platforms may place cookies if you interact with embedded social sharing buttons, though we minimize use of such features. Content delivery networks use cookies to optimize content delivery and improve load times across geographic regions. Advertising partners may use cookies to deliver relevant advertisements based on your interests, though you can opt out of these through your browser settings or our preference center. All third-party cookies are subject to the privacy policies of their respective providers.

How We Use Cookie Data

We use information collected through cookies for several purposes. Essential operations include authenticating users, maintaining secure sessions, preventing fraud and abuse, and delivering requested services. We analyze aggregate usage data to improve content quality, optimize user interface and navigation, identify and fix technical issues, and develop new features based on user behavior. Personalization allows us to recommend relevant articles and research, remember your preferences across sessions, customize your experience based on past activity, and provide location-specific content where appropriate. Marketing activities include measuring campaign effectiveness, delivering relevant promotional content, understanding which channels drive traffic, and optimizing our marketing spend. All data processing complies with applicable privacy laws and our stated privacy commitments.

Cookie Duration and Persistence

Cookies can be classified by duration into session cookies and persistent cookies. Session cookies are temporary and deleted automatically when you close your browser. They enable essential functions like shopping cart management and form navigation. Persistent cookies remain on your device for a specified period or until manually deleted. They remember your preferences, login status, and behavioral patterns across visits. The duration of persistent cookies varies based on their purpose: essential security cookies may last for your session only, preference cookies typically last 12 months, analytics cookies may persist for up to 2 years, and marketing cookies generally last 30 to 90 days. You can delete cookies at any time through your browser settings, though this may affect site functionality and require you to re-enter preferences.

Managing Your Cookie Preferences

You have several options to control how cookies are used on your device. Our cookie banner appears when you first visit our site, allowing you to accept all cookies, reject non-essential cookies, or customize your preferences by category. You can change your preferences at any time by accessing the cookie settings link in the footer of any page. Your browser settings provide additional control over cookies. Most browsers allow you to block all cookies, accept only first-party cookies, delete cookies on exit, or receive notifications before cookies are set. Instructions vary by browser, but settings are typically found in the privacy or security section. Be aware that blocking all cookies may prevent you from using certain website features and logging into your account. Industry opt-out tools like the Digital Advertising Alliance's opt-out page or the Network Advertising Initiative's opt-out tool allow you to opt out of interest-based advertising from participating companies. Mobile device settings provide options to limit ad tracking through device-level privacy controls.

Consent and Legal Basis

Our use of cookies is based on several legal grounds. Essential cookies are placed based on our legitimate interest in providing the services you request and ensuring website security. For non-essential cookies, we rely on your explicit consent obtained through our cookie banner. You can withdraw consent at any time by adjusting your cookie preferences, though this will not affect the lawfulness of processing before withdrawal. For users in the European Economic Area, United Kingdom, and other jurisdictions with strict cookie laws, we obtain opt-in consent before placing non-essential cookies. In other jurisdictions, we provide clear notice and opt-out mechanisms. We periodically review and update our consent mechanisms to ensure compliance with evolving regulations. Your cookie choices are stored locally on your device and respected across your sessions until you clear your browser data or change your preferences.

Cookies and Personal Data

Some cookies may collect or process personal data, particularly when combined with other information we hold about you. When cookies contain personal data, that data is protected in accordance with our Privacy Policy and applicable data protection laws. Personal data collected through cookies may include your IP address, unique device identifiers, browsing history on our site, search queries and content interactions, and inferred interests and demographics. We implement appropriate security measures to protect cookie data, including encryption of sensitive information, regular security assessments, access controls limiting who can view data, and retention policies ensuring data is not kept longer than necessary. If you create an account, we may associate cookie data with your account to provide personalized services and improve your experience. You have the same rights regarding cookie data as other personal data, including rights to access, correction, deletion, and portability where applicable.

Cookies for Logged-Out Users

Even if you are not logged into an account, we use certain cookies to provide functionality and analyze usage. Essential cookies enable basic website operations for all visitors, while analytics cookies help us understand aggregate traffic patterns without identifying individual users. We may use cookies to remember your cookie consent preferences, language and regional settings, and recently viewed content to enable features like "recently read" sections. Marketing cookies may track your interactions to deliver relevant advertisements, though you can opt out of these at any time. For logged-out users, we minimize data collection and rely primarily on aggregated, anonymized data for analytics and improvement purposes. Creating an account provides enhanced features and more personalized content but is not required to use our free services.

Do Not Track Signals

Some browsers support "Do Not Track" (DNT) signals that request websites not track your browsing activity. Currently, there is no universal standard for how websites should respond to DNT signals. At present, our website does not respond to DNT signals due to the lack of industry consensus. However, we provide robust cookie controls through our preference center that allow you to limit tracking regardless of browser settings. You can opt out of non-essential cookies, manage third-party advertising cookies, and adjust your preferences at any time. We support initiatives to develop clear DNT standards and will update our practices if consensus emerges. In the meantime, we encourage you to use our cookie controls and browser settings to manage your privacy preferences effectively.

Updates to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in our use of cookies, legal requirements, or best practices. When we make material changes, we will notify you by posting a prominent notice on our website, updating the "Last Updated" date at the top of this policy, or in some cases, sending an email notification to registered users. We encourage you to review this policy periodically to stay informed about how we use cookies. Significant changes affecting your rights or expanding data collection will be accompanied by requests for renewed consent where required by law. Your continued use of our services after changes are posted constitutes acceptance of the updated Cookie Policy, except where new consent is specifically required.

International Data Transfers Through Cookies

Some cookies and tracking technologies may result in your data being transferred to countries outside your jurisdiction. We ensure appropriate safeguards are in place for such transfers, including using service providers that comply with international data protection frameworks, implementing Standard Contractual Clauses where required, and ensuring adequate security measures protect data in transit and storage. Third-party cookie providers may process data in the United States or other countries. We select partners carefully and require them to maintain appropriate data protection standards. If you have concerns about international data transfers, you can limit non-essential cookies through our preference center, though this may affect certain features and personalization.

Children's Privacy and Cookies

Our services are not directed to children under 16, and we do not knowingly collect information from children through cookies or other means. If you are under 16, please do not use our website or accept cookies without parental or guardian supervision. Educational institutions using our services for students under 16 are responsible for obtaining necessary consents and managing cookie preferences appropriately. We do not use cookies to target advertising to children or to build profiles of child users. If we become aware that we have collected data through cookies from a child under 16 without proper consent, we will take steps to delete such data promptly.
