GuessFast
Privacy Policy
Last updated: 7 November 2026
In short
GuessFast has no email sign-up and uses no GPS location; the game gives your device an anonymous ID through Firebase. Your daily scores appear on public leaderboards with your nickname and a country taken from your device region. The game shows Google AdMob ads and we request non-personalised ads. To delete your data you need to write to neuvikon@gmail.com; there is no delete button in the app.
Who is responsible
GuessFast is published by Neuvikon. Neuvikon is the data controller under the GDPR and Turkey's Law No. 6698 (KVKK).

What this covers
This policy covers GuessFast, published by Neuvikon for Android and iOS, and the Firebase infrastructure that holds its game data. The game has the Number, Estimate, Movie, Person and Higher or Lower games and online PvP.
What we process and why
| Data | Purpose | Legal basis | Kept for |
|---|---|---|---|
| Anonymous user ID generated by Firebase | Linking your scores, name and rating to the same player | GDPR Art. 6(1)(b): performance of a contract | Not deleted automatically; kept until you ask us to delete it |
| IP address and user agent | Security and abuse prevention during anonymous sign-in | GDPR Art. 6(1)(f): legitimate interest in protecting the game from abuse | Firebase keeps logged IP addresses for a few weeks |
| Nickname (approved name or temporary Guest_1234 name) | Showing you on leaderboards and in PvP, keeping names unique | GDPR Art. 6(1)(b): performance of a contract | Not deleted automatically; kept until you ask us to delete it |
| The nickname you request and its approval status | Reviewing names by hand before they are published | GDPR Art. 6(1)(f): legitimate interest in keeping leaderboards free of inappropriate names | An approved request becomes your name record. A rejected request is deleted; the rejected name stays in your player record until you see the notice |
| Daily round results: score, date, attempts, time, guesses and answers, per-game totals | Daily, weekly, monthly and overall leaderboards, streaks, daily summaries | GDPR Art. 6(1)(b): performance of a contract | Not deleted automatically; kept until you ask us to delete it |
| Country (from your device region setting). Older records may hold a city name | Showing a country label next to your name on leaderboards | GDPR Art. 6(1)(f): legitimate interest in giving leaderboards an international context | Kept with the score record until you ask us to delete it |
| PvP data: nickname, rating, match count, guesses, the secret number you set, room and matchmaking records | Running the match, matchmaking, calculating ratings and leagues, preventing cheating | GDPR Art. 6(1)(b): performance of a contract | Rating is kept until you ask us to delete it. Room and matchmaking records are not deleted automatically; a four-digit room code overwrites its room record when reused |
| Ad data collected by Google: advertising ID, IP address and the general location derived from it, ad interactions, diagnostics | Showing non-personalised ads, measuring ads, preventing fraud | GDPR Art. 6(1)(f): legitimate interest in funding a free game with ads | Google applies its own periods; see the Ads section below |
| Your email address and message when you write to us | Answering your support request | GDPR Art. 6(1)(f): legitimate interest in answering you | Up to 1 year after the matter closes |
| Details in a deletion or data rights request | Completing your request within the legal time limit | GDPR Art. 6(1)(c): legal obligation | Up to 1 year after the matter closes |
How data is collected
The anonymous ID is created automatically when you first open the game. You type the nickname yourself. When you finish a daily round, your result and your current country are saved automatically; the country is read from your device region setting. PvP data is created during a match. Google's ad software collects ad data automatically. Free play, XP, achievements and settings stay on your device and never reach us.
Do you have to provide it
A nickname is optional; without one you appear as Anonymous on leaderboards and under a generic player name in PvP. Daily rounds and PvP are optional too, and free play results are not written to leaderboards. The anonymous ID is created automatically at launch and the country label is written automatically in daily rounds; you cannot turn these off in the game. Notification permission and the iOS tracking permission are optional, and the game keeps working without them.
What we do not collect
- GPS or device location. Current versions do not ask for location permission.
- Email, phone number or password. The game has no sign-up that asks for them.
- Contacts, photos, camera or microphone data.
- In-game chat. Players see only nicknames, scores and match moves.
- Firebase Analytics and Crashlytics. This game does not use them.
- Payment details. The game has no in-app purchases.
Leaderboards and other players
Your nickname, country, scores and PvP rating are public on leaderboards. These records can be read not only inside the game but also directly from the database, without signing in. A name awaiting approval also sits in your player record. Nicknames are reviewed by hand before they are published, and until then you play as a temporary Guest_1234 name.
In PvP your opponent sees your nickname, rating and guesses, and sees the number you set once the round ends. Other signed-in players can also technically read room records. The game has no chat.
Ads
The game shows Google AdMob banner, interstitial and rewarded ads. We send every ad request as non-personalised. Even for these ads, Google may use the advertising ID and IP address for frequency capping, measurement and fraud prevention, and may estimate general location from the IP address.
On iOS the game asks for Apple's tracking permission (ATT) at launch; if you refuse, the advertising ID is not shared. Apart from this, the app has no separate ad consent screen.

Notifications and Android permissions
Daily round and streak reminders are scheduled on your device, are not sent from our server, and we receive no notification token. Android has a run-at-startup permission so these reminders survive a phone restart.
Location, storage and draw-over-other-apps permissions may also appear in the Android package. They come from libraries we use and from the stock project template; the game does not ask you for them and does not use them.
City data from older versions
Older versions of the game from early 2026 took a city name from device location for leaderboards. Current versions use only the country from your region setting. Score records from that period may still hold a city name; write to us to have it deleted.
Who receives data
| Party | Role | Location |
|---|---|---|
| Firebase (Google Cloud) | Generates the anonymous ID, handles sign-in, and stores score, name and PvP data. | Authentication in the US; game data on Google Cloud servers outside Turkey |
| Google AdMob | Shows ads. Receives the advertising ID, IP address, ad interactions and diagnostics. | Global |
| Google Play | Distributes the game on Android and handles download records under its own policy. | Global |
| Apple App Store | Distributes the game on iOS and handles download records under its own policy. | Global |
| Google (Gmail) | Email service where support messages are stored. | Global |
We use these parties only for the purposes above and expect them to protect the data to the same or an equivalent standard as this policy. We do not sell your data. We may disclose information where a lawful request from an authority requires it.
International transfers
Anonymous sign-in is processed in Firebase data centres in the US. Score, name and PvP data sit on Google Cloud servers outside Turkey, and ad data and support email on Google's infrastructure abroad, so your data may leave your country. For users in Turkey this is a transfer abroad under KVKK Art. 9.
Security
Traffic between the game and Firebase and Google is encrypted. Database rules let each player write only their own scores and hide the number you set in PvP from your opponent until the round ends. Leaderboard data is public by design, so do not put personal details in your nickname.
Deleting your data
There is no delete button in the app. To delete your data, write to neuvikon@gmail.com with your nickname or Guest name and a day you played: you cannot see your anonymous ID in the game, so we find you by these details. We delete your scores, name, rating, room and matchmaking records and your anonymous account. Daily totals that carry no identity remain. Firebase clears deleted account data from its backups within up to 180 days. Uninstalling the game deletes only the data on your device, not the records on the server; if you reinstall, you get a new ID and the old records stay where they are. You can reset your advertising ID in your device settings.
Children
GuessFast is listed as 4+ on the App Store and PEGI 3 on Google Play, but these ratings only describe how suitable the content is. The game is not designed for children: it calls for general knowledge of films and famous people, and it has ranked PvP, public leaderboards and ads. We do not ask for age, so we do not know how old players are, and we do not aim to collect data from children. If a young child plays, make sure they do not use their real name as a nickname. If you are a parent and want your child's data deleted, write to us with the nickname and we will delete it.
Your rights
You may ask for access to your data, correction, erasure, restriction and portability, and you may object to processing based on legitimate interests. Where processing rests on consent, you may withdraw it at any time, without affecting earlier processing. Turkish users have the rights in KVKK Art. 11, listed on our data protection notice page.
Write to the address above with your name and request. It is free, and we answer within one month at the latest (30 days under KVKK). KVKK applications are made in Turkish.
Complaints
You can complain to us first. You may also complain to your local data protection authority (in the UK, the ICO) or, in Turkey, to the Personal Data Protection Board (KVKK).
Changes
When this text changes, the date at the top changes too. Significant changes are also announced in the product or its release notes. We do not respond to browser Do Not Track signals.
