Privacy
In short: your progress, settings and badges stay in your browser. Visit statistics only run if you allow them. We never ask for your microphone, camera or location.
Data controller
Bumba Teknoloji Limited Şirketi, Ataşehir, Istanbul. For questions and data protection (KVKK) requests: bilgi@bumbagroup.com.
What stays in your browser
The items below are kept in your browser's local storage (localStorage). They belong to this site, are never sent to a server and stay until you delete them. In the cookie banner they are in the "Necessary" group; the legal basis is legitimate interest under KVKK art. 5/2-f: the data does not leave your device, and you can see and delete it.
| Key | What it holds | Why |
|---|---|---|
bumba-cerez | Your cookie choice and the policy version | So we don't ask again on every page |
akis-tema | Your Night or Paper theme choice | To remember your theme |
akis-dil | Your Turkish or English choice | To remember your language |
akis-ayarlar | Your sound settings: headphones or speakers, head profile, volume, delay, camera, play without sight | To play the game's sound the way you set it |
akis-kuyu | Your badges and the counters needed to work them out | To show your badges and progress |
Badges
The badges you earn are stored only in this browser, under the "akis-kuyu" key: the badge's id and the day you earned it (no time). The counters some badges need are kept there too: the sound memories you found, how many days in a row you played and the last day you played. No activity log, name or email is kept.
This data is first-party, never sent to a server and kept until you delete it. To delete it, use "Delete badges" on the Badges screen in the game, or clear this site's data in your browser. The legal basis is KVKK art. 5/2-f; no consent is needed. Your badges are not shown to anyone else.
If you allowed statistics, the first time you earn a badge we count which badge it was, with the same browser, device, country and city details as a page visit. No name, email or progress is sent.
Visit statistics (Umami)
If you choose "Accept" in the cookie banner, or turn statistics on in the preferences, we count visits with Umami. Umami runs on our own server (istatistik.bumba.tr) and uses no cookies. If you don't allow it, Umami never loads.
Umami processes your browser, device type, language, and the country and city derived from your IP address; the IP address itself is not stored. Visits are linked to a pseudonymous session, which is why we don't call this data anonymous.
What is counted: the pages you visit, joining the mailing list, searching the site (the number of results, not what you typed), changing language or theme, finishing a labyrinth (only the labyrinth's id) and earning a badge (only the badge's id).
The legal basis is your explicit consent. You can change your choice at any time with the "Cookie preferences" link at the bottom of every page. Our full cookie policy: https://bumbagroup.com/cerez-politikasi?dil=en
Mailing list
The mailing list form in the footer goes to Bumba Group's shared list service. Before you join it shows the privacy notice in a window, and only sends when you choose "I accept". The notice: https://bumbagroup.com/liste/aydinlatma?dil=en
Other sources
The Bumba Games badge in the footer and the mailing list notice load from bumbagroup.com, so your IP address reaches that server too. The font and all of the game's files come from our own server. There are no other outside sources.
Microphone, camera, location
The site and the game never ask for microphone, camera or location access.
Your rights
To use your rights under KVKK art. 11 (to ask what we hold, correct it, delete it or object), write to bilgi@bumbagroup.com. What is kept in your browser you can delete yourself, right away.
