Cookie Notice

“Cookies” are small text files placed on your device by the websites you visit. We also use closely related technologies — local storage, session storage, IndexedDB, software-development-kit identifiers, and pixel-style image requests. Throughout this notice, “cookies” covers all of these, unless the context says otherwise.

Cookies can be set by the website you are visiting (“first-party”) or by a third party loaded into the page (“third-party”). They can be deleted at the end of a session (“session cookies”) or persist for a defined period (“persistent cookies”).

We use a small set of cookies to deliver the Service, remember your preferences, and understand — at an aggregate, pseudonymous level — how the Website is used. We do not use advertising cookies, we do not run cross-site behavioral tracking, and we do not share information with third-party advertising networks.

1. Strictly necessary

These cookies are required for the Website to function. They authenticate signed-in users, secure forms against cross-site request forgery, balance traffic across servers, and remember whether you accepted the cookie banner. They cannot be turned off through the Website because the Service would not work without them. Examples: authentication session, CSRF token, load-balancing identifier.

2. Preferences

These cookies remember the choices you make so the Website behaves the way you expect on the next visit. Examples: locale (en-US, es-MX, ru-RU), reduced-motion preference, theme.

3. Analytics

These cookies collect aggregated, pseudonymous information about how visitors use the Website — pages visited, features clicked, errors encountered. We use this information only to fix what does not work and to prioritize what does. In the EU/EEA, the UK, and other jurisdictions where consent is required by law, analytics cookies are loaded only after you give consent. Provider: Google Firebase Analytics.

• Google LLC (Firebase Hosting, Firebase Authentication, Firebase Analytics) — for hosting, authentication, and pseudonymous analytics.
• Apple Inc. — when you sign in with Apple ID or download the iOS App.

Each provider operates under its own privacy policy. Where we share personal data with a provider, we do so under a written data-processing agreement and the safeguards described in our Privacy Policy.

EU/EEA, UK, and similar jurisdictions

If you visit the Website from the EU, the EEA, the UK, or another country with comparable rules, we ask for your consent before loading non-essential cookies. You can grant or refuse consent through the cookie banner shown on your first visit, and you can change your choice at any time through the cookie-preferences link in the footer.

United States and California

We do not “sell” personal information and we do not “share” it for cross-context behavioral advertising as those terms are defined in the California Consumer Privacy Act, as amended by the CPRA. We honor the Global Privacy Control browser signal where it is technically detected.

Russian Federation

Where Russian Federal Law No. 152-FZ applies, we treat the use of identifiers contained in cookies as the processing of personal data and we rely on the legal basis described in our Privacy Policy.

Browser and device controls

You can also use your browser settings to block or delete cookies. Most browsers let you do this from a “Privacy” or “Site settings” menu. Mobile operating systems offer similar controls — for example, Apple App Tracking Transparency on iOS. Blocking strictly necessary cookies will break the Website.

Most browsers offer a “Do Not Track” signal. There is currently no industry standard for what this signal means. Where we can detect the W3C Global Privacy Control signal, we treat it as a valid opt-out under the California CCPA/CPRA and we apply the corresponding preferences.

• Session cookies are deleted automatically when you close the browser.
• Authentication cookies typically last up to 30 days, or shorter if you sign out.
• Preference cookies last up to 12 months and are renewed when you visit again.
• Analytics cookies last up to 14 months.

We may update this Cookie Notice if we add or remove a cookie, change a provider, or update the legal framework around cookies. The “Last updated” date at the top reflects the version currently in force.
