This Cookie Policy explains how Integralcalculator.info may use cookies, sessions, local storage, and similar browser technologies. These technologies help the website remember information, protect forms, maintain sessions, measure usage, support advertising where enabled, and store visitor choices such as policy acceptance.
What Cookies Are
Cookies are small text files placed by a website or third-party service in your browser. Local storage is a browser feature that can store small pieces of data on your device. Similar technologies may include pixels, scripts, session identifiers, and security tokens. Some are necessary for the site to work, while others support measurement or advertising.
Essential Cookies and Storage
Essential technologies may be used for PHP sessions, login state, CSRF protection, form security, calculator request handling, consent preferences, account activation, password reset, Premium flows, and general site operation. Without these, parts of the website may not function correctly.
Security Cookies
Security tools may use cookies or browser signals to reduce spam, fake registrations, automated abuse, brute-force attempts, and suspicious form submissions. For example, if Cloudflare Turnstile or similar protection is enabled, it may process browser signals to verify that requests are legitimate.
Preference Cookies
Preference storage may remember choices such as policy acceptance, interface state, language-related display settings, or similar convenience options. The Terms, Privacy, and Cookie acceptance modal uses local browser storage so visitors are not repeatedly asked to accept the same notice on every page view.
Analytics Cookies
If analytics tools are enabled, cookies or scripts may help measure page views, traffic sources, device categories, popular calculators, guide usage, and site performance. This information helps us understand whether pages are useful, find technical issues, and improve the educational experience.
Advertising Cookies
If advertising is enabled, advertising partners such as Google may use cookies or similar technologies to serve ads, limit repeated ads, measure ad performance, detect invalid traffic, and personalize ads where allowed. Advertising behavior may depend on your region, browser settings, consent choices, and the advertising provider policies.
Advertising Controls
Where advertising partners provide controls, you may be able to adjust ad personalization, reset advertising identifiers, use browser privacy settings, or choose provider opt-out tools. These controls may not remove every advertisement, but they can affect personalization, measurement, and repeated ad delivery. Some choices are stored by the browser or advertising provider, not by Integralcalculator.info.
Payment and Account Cookies
If Premium or account features are enabled, payment providers and account flows may use cookies or sessions to keep checkout, redirect verification, login, and account status working. Payment card or wallet details should be handled by the payment provider, not directly by this website.
Third-Party Services
Third-party providers may set or read cookies when their services are active. These may include analytics, advertising, security, email, payment, hosting, or embedded-service providers. Their own cookie and privacy policies may apply.
How Long Cookies Last
Session cookies usually expire when the browser is closed or after a short period. Persistent cookies or local storage may remain longer so preferences, consent choices, login state, or security settings can be remembered. You can clear them through your browser settings.
Your Choices
You can block, delete, or limit cookies through your browser. You may also use browser privacy controls, ad personalization settings, or provider opt-out tools where available. Blocking essential cookies may affect login, forms, calculator requests, Premium checkout, contact messages, or consent storage.
Browser Settings and Shared Devices
Cookie controls are usually managed per browser and per device. If you use a shared computer, school device, library device, private browsing window, or browser that clears data automatically, the consent notice may appear again. Clearing cookies or local storage may also sign you out, remove saved preferences, or reset security and consent choices.
Do Not Track and Global Signals
Some browsers send privacy signals such as Do Not Track or global preference controls. Website and provider support for these signals can vary. Where technically feasible and legally required, tools may respect recognized preference signals, but essential cookies may still be used to provide security, sessions, forms, and calculator access.
Consent Notice
When the consent modal appears, continuing requires acknowledging the Terms and Conditions, Privacy Policy, and this Cookie Policy. This acknowledgement is stored in your browser so the notice does not appear repeatedly on the same device and browser.
Updates and Contact
We may update this Cookie Policy when website features, analytics, advertising, account tools, payment flows, or security services change. Questions can be sent through the Contact Us page.
