1. What Are Cookies?

Cookies are small text files that a website stores on your browser or device when you visit it.

Cookies may allow a website to:

• operate securely;
• maintain a browsing session;
• remember language and privacy preferences;
• understand how visitors use the website;
• measure website performance;
• prevent fraud and abuse;
• display and measure advertisements.

Cookies usually contain an identifier and certain technical information. They do not normally contain the complete content of calculator entries, contact messages or documents.

2. Similar Technologies

In addition to cookies, Hesabla and authorized third parties may use similar technologies, including:

• local storage;
• session storage;
• software development tags;
• pixels and web beacons;
• scripts;
• device or browser identifiers;
• server-side identifiers;
• consent-management signals.

These technologies may store information on your device, access information already stored on your device or transmit limited technical information when a page or feature is used.

References to “cookies” in this Policy also include these similar technologies where appropriate.

3. First-Party and Third-Party Cookies

First-party cookies

First-party cookies are placed directly by Hesabla.com or on our behalf.

They may be used for website security, session management, language preferences, consent choices and other website functions.

Third-party cookies

Third-party cookies are placed or accessed by an organization other than Hesabla.

For example, third parties providing analytics, advertising, security, hosting or consent-management services may place or read cookies when their technology is active on our website.

Third-party cookies are governed by the privacy and cookie practices of the relevant third party in addition to this Cookie Policy.

4. Session and Persistent Cookies

Session cookies

Session cookies normally expire when you close your browser or after a short period of inactivity.

They may be used to maintain website functionality during a single visit.

Persistent cookies

Persistent cookies remain on your device for a defined period or until you remove them.

They may be used to remember preferences, recognize consent choices, measure recurring visits or support advertising and analytics.

The duration of a cookie depends on its purpose, configuration and provider.

5. Categories of Cookies We May Use

Strictly necessary cookies

Strictly necessary cookies support functions required for the website to operate safely and correctly.

They may be used for:

• website and server security;
• protecting forms against unauthorized or fraudulent submissions;
• maintaining a temporary session;
• load balancing and network management;
• recording privacy and consent choices;
• detecting technical errors or abuse;
• delivering a feature specifically requested by the user.

Because these technologies are necessary for basic website operation or for providing a service requested by the user, they may not always require consent where an applicable legal exemption exists.

Disabling them may cause parts of the website to stop working correctly.

Preference and functionality cookies

Preference cookies allow the website to remember choices you have made.

They may remember:

• selected language;
• display preferences;
• calculator settings;
• recently selected options;
• cookie and privacy preferences.

These cookies help provide a more convenient and consistent experience.

Where required by applicable law, optional preference cookies will be used only after consent.

Analytics and performance cookies

Analytics cookies help us understand how visitors interact with Hesabla.

They may provide aggregated or statistical information about:

• the number of visitors;
• pages and calculators visited;
• general traffic sources;
• approximate geographic regions;
• time spent on pages;
• interactions with buttons, links and website features;
• browser, device and operating-system categories;
• page loading performance;
• errors and technical problems.

We use this information to improve website performance, calculators, content, navigation and user experience.

Where required by law, analytics cookies will not be activated until the user has provided the relevant consent.

Advertising cookies

Advertising cookies may be used on selected pages where advertising is enabled, including article pages.

They may support:

• displaying advertisements;
• choosing contextual or personalized advertisements;
• limiting how often an advertisement is shown;
• measuring advertisement impressions and interactions;
• preventing invalid traffic, fraud and abuse;
• preparing advertising reports;
• measuring advertising effectiveness;
• remembering advertising privacy choices.

Advertising cookies may allow advertising providers to recognize a browser or device across different websites.

Where legally required, advertising cookies and personalized advertising will be activated only after the user has made the appropriate consent choice.

6. Technologies That May Be Used

The following table describes the general categories of technologies that may operate on Hesabla.com. The exact cookie names, providers and durations may change depending on our configuration and the services currently enabled.

Not every technology described in this table will necessarily be active during every visit.

The most current information about active vendors, purposes and cookie durations may also be shown through the Cookie Settings or Privacy Settings interface, where available.

7. Google Analytics

Hesabla may use Google Analytics to measure and understand website usage.

Depending on our configuration and your consent choice, Google Analytics may use cookies or related identifiers to distinguish visits, measure sessions and prepare statistical reports.

Google Analytics may process information such as:

• pages visited;
• approximate visit times and session duration;
• general referral source;
• interactions with website features;
• browser and device characteristics;
• approximate geographic region;
• analytics identifiers.

We use analytics information to understand general website usage and improve our services.

We do not intend to send values entered into Hesabla calculators to Google Analytics as information intended to identify a user or create an advertising profile.

Where consent is required, Google Analytics storage will be controlled by the choice made through our consent-management system.

Users may also use Google’s official Analytics opt-out browser tool where supported.

8. Google AdSense and Advertising Cookies

Hesabla may use Google AdSense to display advertisements on selected pages.

Third-party vendors, including Google, may use cookies or similar technologies to serve advertisements based on a user’s previous visits to Hesabla.com or other websites.

Google’s use of advertising cookies may allow Google and its advertising partners to serve advertisements based on visits to Hesabla and other websites on the Internet.

Depending on the user’s location, consent choice and advertising settings, advertisements may be:

• contextual advertisements;
• limited advertisements;
• non-personalized advertisements;
• personalized advertisements.

Users may control personalized advertising through Google’s advertising and privacy settings.

Where other authorized advertising vendors or networks are used, information about those providers and their purposes may be shown through the consent-management platform.

Advertising technologies may use cookies, browser identifiers, IP addresses, pixels and similar technical information for ad delivery, measurement, reporting and invalid-traffic prevention.

9. Consent Management

Where applicable law requires consent, Hesabla provides a cookie banner or consent-management interface before activating optional technologies.

The interface may allow users to:

• accept all optional cookies;
• reject optional cookies;
• make choices by cookie category;
• review advertising vendors and purposes;
• save their preferences;
• withdraw or change consent later.

Rejecting optional cookies should not prevent access to the main calculators and informational content, although certain optional or personalized functions may be limited.

Strictly necessary technologies may continue to operate because they are required for security, privacy management or basic website functionality.

10. Users in the EEA, United Kingdom and Switzerland

For users in the European Economic Area, the United Kingdom and Switzerland, Hesabla may use a Google-certified consent-management platform integrated with the IAB Europe Transparency and Consent Framework where required for Google advertising services.

The consent interface may provide information about:

• the purposes for which information is processed;
• the advertising and technology providers involved;
• whether information may be stored or accessed on a device;
• personalized and non-personalized advertising choices;
• measurement, security and fraud-prevention purposes;
• how consent can be withdrawn.

Optional analytics and advertising storage will be handled according to the user’s consent choice where required by applicable law.

11. Calculator Inputs and Cookies

Cookies are not intended to store the full content of values entered into Hesabla calculators.

A calculator may temporarily use browser or session storage where this is necessary to:

• preserve information while moving between calculation steps;
• restore a calculator after a page refresh;
• remember options chosen by the user;
• present the requested calculation result.

Unless a calculator clearly explains otherwise, these values are not intended to be used for behavioral advertising or to create an individual advertising profile.

Users should avoid entering information that directly identifies them unless a specific feature requires it.

12. Managing Your Cookie Choices

Where available, you can review or change your choices through the Cookie Settings or Privacy Settings link displayed on the website.

Withdrawing consent does not affect the lawfulness of processing that occurred before consent was withdrawn.

Changing your settings may:

• prevent new optional cookies from being placed;
• instruct supported technologies not to use certain storage;
• remove or replace some consent-related identifiers;
• change whether personalized advertising or analytics operates.

Previously stored cookies may remain on your device until they expire or are deleted through your browser settings.

13. Browser Controls

Most browsers allow you to inspect, block or delete cookies.

Browser settings may allow you to:

• delete existing cookies;
• block all cookies;
• block third-party cookies;
• allow cookies only from selected websites;
• receive a warning before a cookie is stored;
• clear cookies when the browser closes.

Blocking all cookies may affect website security, language preferences, forms and other functionality.

Browser controls are separate from Hesabla’s consent interface. For the most complete control, you may need to use both.

14. Third-Party Services

Third-party services may change their technologies, cookie names and retention periods independently.

Their processing is also governed by their own privacy and cookie documentation.

Potential third-party service categories include:

• analytics providers;
• advertising providers;
• hosting and content-delivery providers;
• security and fraud-prevention providers;
• consent-management providers;
• embedded media or external-content providers.

Hesabla does not control all cookies placed after you leave our website and visit an independent third-party page.

15. Cookie Retention

We aim to keep cookies and similar identifiers only for as long as reasonably necessary for their intended purpose.

Retention may depend on:

• whether the cookie is a session or persistent cookie;
• the selected consent choice;
• security and fraud-prevention needs;
• analytics configuration;
• advertising-provider settings;
• legal and compliance requirements.

Consent records may be retained for a reasonable period to remember user choices and demonstrate compliance.

A cookie may be renewed when you revisit the website, depending on its configuration.

16. Children’s Privacy

Hesabla provides general and educational tools that may be useful to younger users.

We do not intend to use calculator inputs to build advertising profiles about children.

Where age-specific privacy or consent requirements apply, advertising and optional tracking technologies should be configured accordingly.

A parent or legal guardian should assist a young user with privacy choices where required by applicable law.

17. Changes to This Cookie Policy

We may update this Cookie Policy when:

• we add or remove cookies;
• a calculator or website feature changes;
• we introduce a new analytics, advertising or security provider;
• providers change their technologies;
• legal or regulatory requirements change;
• our consent-management system changes.

The latest version will be published on this page with an updated effective date.

Where a material change affects an existing consent choice, we may display a new consent message or ask users to review their preferences again.
