Cookie Policy

Version 2026-08 · Last updated 21 August 2026 · Effective 21 August 2026

Every cookie and similar technology Open Gym uses, what it does, and how long it lasts. Only the strictly necessary ones are set without asking you first.

1. What cookies are

A cookie is a small text file stored on your device by your browser. We also use comparable technologies — such as values held in your browser's local storage — and everything in this policy applies to those too.

Under Hungarian Act C of 2003 on electronic communications (§155) and the ePrivacy Directive, we may store strictly necessary cookies without consent, but we need your consent before setting any others. Where a cookie also involves processing personal data, the Privacy Policy explains that processing.

2. Strictly necessary cookies

These are required to operate the Platform and are set without consent. You cannot turn them off and still use the site.

Stripe sets its own cookies on its hosted checkout page for fraud prevention and payment security. Those are governed by Stripe's privacy policy.

3. Analytics cookies (consent required)

These are set only after you consent, and you can withdraw consent at any time.

In the native iOS and Android apps we do not track you. The apps load no advertising cookies or SDKs, do not follow you across other companies' apps or websites, and do not combine what we collect with data obtained from third parties for advertising. On the website, advertising cookies are used only if you allow them — see section 4. We never sell your data or share it with data brokers.

4. Advertising cookies (consent required, website only)

With your permission, the website uses advertising cookies to measure whether our ads worked — for example, whether someone who clicked an Open Gym ad on Google went on to sign up. They are never set in the native apps, never set before you choose, and we do not use them to show you ads on other sites based on your activity here.

If we add another advertising platform (such as Meta), it is listed here first and you are asked again before it runs.

6. Browser controls

Every major browser lets you block or delete cookies in its settings. Blocking strictly necessary cookies will break sign-in and the cart. You can also opt out of Google Analytics across all sites with Google's opt-out browser add-on.

7. Changes

We update this policy whenever we add or remove a cookie. The version and date at the top of the page tell you which version is current.
