Cookies are small text files that a website stores on your browser or device. They help a website remember information about your visit, such as your login status, preferences, or settings.
This Cookie Policy also covers similar technologies, including:
localStorage, sessionStorage, and IndexedDB;For simplicity, this policy refers to all of these technologies as “cookies and similar technologies.”
MEPTools.com uses, or may use, cookies and similar technologies to:
The consent mechanism on MEPTools.com is Google's certified Consent Management Platform (AdSense Privacy & messaging, IAB TCF v2.2 + Google Consent Mode v2).
The consent message is shown to users in the EEA, UK, Switzerland, UAE, and Saudi Arabia, where prior consent is required. In other regions, non-essential technologies may operate without a prompt, subject to local law.
Consent choices are applied through Google Consent Mode, which governs analytics and advertising storage. Browser Do Not Track / Global Privacy Control signals are honored as a signal to deny non-essential storage.
You can change or withdraw your choice at any time via the "Cookie Settings" control in the site footer (where the consent message is available), or through browser/device controls.
Rejecting or withdrawing consent for non-essential cookies will not disable strictly necessary technologies that are required to operate MEPTools.com, authenticate users, maintain security, process payments, prevent abuse, or provide services requested by the user.
Consent choices are stored by the CMP client-side; clearing browser storage or switching device/browser resets them.
The table below is category-based. Exact cookie, storage, SDK, or identifier names may change as browsers, operating systems, and third-party providers update their services.
| Category | Purpose | Examples of providers or technologies | Consent / control | Retention |
|---|---|---|---|---|
| Strictly necessary | Required to operate MEPTools.com, authenticate users, protect accounts, process payments, maintain security, prevent abuse, remember required consent choices, and provide services requested by the user. | Firebase Hosting, Firebase Authentication, Firestore, Google Cloud, Stripe, essential security, hosting, and consent technologies. | Always active because the service cannot operate properly without them. | Usually session-based or retained only for as long as necessary for account, security, legal, payment, fraud-prevention, or service operation purposes. |
| Functional / preferences | Used to remember choices such as dark/light mode, language, region, units, last selected tool settings, saved inputs, and other user interface preferences. | MEPTools.com browser storage, Firebase-related storage, localStorage, sessionStorage, IndexedDB. | User-controlled where the consent mechanism provides this option or where required by law. | Up to 6 months, unless you clear your browser/app storage earlier or the setting is replaced. |
| Analytics | Used to understand how users interact with MEPTools.com, which pages or tools are used, and how the service can be improved. | Firebase Analytics and related Google services, where enabled. | Governed by Google Consent Mode: denied by default in the EEA/UK/Switzerland/UAE/Saudi Arabia until the CMP records consent; granted by default elsewhere, subject to the same controls. | Retention depends on the provider settings, analytics configuration, and consent status. |
| Performance / diagnostics | Used to identify errors, crashes, latency, failed requests, and technical reliability issues. | Sentry, Firebase, Google Cloud logs, and similar diagnostic tools. | Strictly necessary for reliability and security — not consent-gated. | Retention depends on the provider settings, diagnostic configuration, and legal needs. |
| Advertising / marketing | Used to deliver, measure, limit, or personalize ads and promotional campaigns, including web and mobile advertising. | Google Ads, Google AdMob, Google advertising identifiers, conversion tracking, pixels, SDKs, and related Google advertising technologies. | Used only after consent where consent is required. Ad personalization depends on user choices, region, platform settings, and applicable requirements. | Retention depends on the provider, campaign settings, user device settings, applicable advertising controls, and consent status. |

Because these technologies are required to provide the service you request, disabling them may prevent parts of MEPTools.com from working.
MEPTools.com may use browser or app storage to remember your preferences and improve your experience. This may include:

Error and crash monitoring (Sentry) is treated as strictly necessary for reliability and security, and is not consent-gated. Some essential security, fraud-prevention, infrastructure, and operational logs are likewise required to protect and operate MEPTools.com. If MEPTools.com later adds non-essential diagnostics that rely on cookies, identifiers, SDKs, or similar technologies, those would be controlled through consent where consent is required.

localStorage, sessionStorage, IndexedDB, and cached site data;Blocking or deleting cookies and similar technologies may affect login, saved preferences, tool settings, subscriptions, payment flows, analytics, diagnostics, advertising, and other parts of MEPTools.com.

Mobile devices may also allow you to reset or restrict advertising identifiers and app tracking settings.
Because browser and device controls are controlled by third parties, MEPTools.com cannot guarantee that all functions will continue to work if you disable cookies, storage, identifiers, or app tracking features.
Cookie, tracking, advertising, and consent requirements vary by country, region, platform, and provider.
Some jurisdictions require prior consent before non-essential cookies, local storage, mobile identifiers, analytics, advertising, personalization, or similar technologies are used. Some advertising platforms may also require specific consent notices, consent signals, certified consent management platforms, or regional privacy messages before ads can be served or personalized.
MEPTools.com may configure the consent mechanism differently by region, app platform, provider requirement, or legal requirement. This may include additional consent options, advertising partner lists, privacy messages, or controls for users in regions with specific requirements.
We may update this Cookie Policy from time to time to reflect changes in our services, technologies, providers, consent mechanism, legal requirements, platform policies, or business operations.
When we make material changes to this Cookie Policy, we will update the version and effectiveDate fields shown at the top of this page.
