Privacy
Open Cap World — opencap.world. Last updated 28 September 2026.
The short version. There is no account, no sign-in and no profile. The game keeps your settings and scores on your own device. The only thing it sends us is your country and two numbers, with nothing attached that could point back at you. Google is involved at two specific moments — if you choose to watch an ad, and once, when you finish your first run, so that advertising we pay for can be measured — and at no other time. Both are described below.
What stays on your device
Saved in your browser's local storage, readable only by this site, and gone if you clear your browsing data:
- Your language, whether sound is muted, and whether the hint card is folded
- Your best score and your lifetime Freshness
- Which themes you have unlocked
- Freshness you earned while offline, waiting to be sent
None of this is transmitted to us and none of it is used to recognise you.
What we receive
When a run starts, the game asks for a one-time ticket: a random number and an expiry, signed by our server so it cannot be edited. When a run ends, the game sends that ticket back with a two-letter country code and, for each run being sent, the number of bottles opened, the Freshness earned and how many milliseconds it took. Nothing in it identifies you — no account, no cookie, no device id, no advertising id. (Google's own code, described below, is the one place a cookie can appear, and only in some countries.)
We store one row per country: the country code, a running total and the time it last changed. We also keep a list of tickets that have already been used, so the same run cannot be counted twice — each entry is only the ticket's random number and when it expires, and it is deleted after a day. There is no table of players, no table of runs and no request log, so there is nothing in it that could be traced back to a person — not as a matter of policy, but because the leaderboard genuinely does not need any of it to work.
How your country is worked out
Cloudflare, which hosts the site, tells the server which country the request came from. Your IP address reaches Cloudflare in the ordinary course of loading any web page, and Cloudflare processes it under their privacy policy — we neither store it nor log it. If Cloudflare cannot determine a country, the game falls back to your browser's language setting.
Advertising
Some themes can be unlocked by watching a rewarded ad. Those ads are served by Google (AdSense / H5 Games Ads).
Google's ad code is not loaded when you open the game. It is fetched only when you open the theme screen, which is the point at which you are heading towards an ad. Until then no request reaches Google at all.
Once loaded, Google may set cookies or read similar identifiers to serve and measure ads, including personalised ones. What Google collects and why is covered by How Google uses information from sites that use its services. You can manage personalised advertising at My Ad Center.
If you are in the EEA, the UK or Switzerland, a Google consent message will ask you before any of this happens, and your answer is passed to Google and its advertising partners.
Not every theme needs one. Themes are cosmetic and change nothing about how the game plays or scores. Some are unlocked by watching an ad; others are unlocked by playing — by opening a number of bottles, or by finding something — and those routes involve Google not at all. Each locked theme says which of the two it is.
Measuring our own advertising
When we pay to advertise this game elsewhere, we need to know whether the people who arrive actually play it. The first time you finish a run — once, ever, on this device — the game reports that to Google Ads. What is sent is that a run was finished. No score, no country, no identifier of any kind is attached, and nothing is sent on any later run.
This code is not loaded when you open the game either. It is fetched at that one moment and not before, so opening the game, reading this page, or playing without finishing reaches Google not at all.
Whether it stores anything depends on where you are. Before the tag runs it is told what it may do, and the answer is not the same for everybody:
- In the EEA, the UK and Switzerland: everything denied. The tag writes no advertising cookie and reads none. Nothing is stored on your device and no identifier is sent — the report arrives without one, and Google estimates rather than matches.
- Everywhere else: the tag may store and send an advertising identifier, which is what lets Google match the report to the ad that brought you. This is a cookie, and it is the one exception to "no cookie" elsewhere on this page.
Personalised advertising is denied in both cases, and so is analytics storage. Measuring whether an ad worked does not need either of them, and we do not ask for permissions the purpose does not require.
Where you are is decided by the same country Cloudflare gives our own server — the one your Freshness is added to. No separate lookup is made, and nothing new is collected to make this decision. If it cannot be worked out, everything is denied.
Your browser's request still reaches Google, which means Google sees your IP address in the ordinary way any request does; that is covered by How Google uses information from sites that use its services.
Children
This game is not directed at children and is not intended for anyone under 13 (or the equivalent age in your country). We do not knowingly collect information from children — and, since we collect no personal information from anyone, there is nothing held about a child to delete.
Your choices
- Clear everything we hold on your device: clear site data for opencap.world in your browser. Scores, themes and settings all go.
- Avoid Google entirely: do not open the theme screen, and leave before a run ends. The game is complete without the theme screen, and the themes that unlock through play stay available.
- Block it: any content blocker that stops
googletagmanager.comstops the conversion report and the cookie with it. The game neither detects that nor behaves differently because of it. - Your country's total: Freshness added to a country cannot be withdrawn, because nothing records that it was yours — it is a single shared number, not a list of contributions.
Changes
If this ever describes something different from what the game does, the game is the bug. The date at the top says when this was last revised.
