Privacy Policy

SifirPro: Multiplication Arcade ("SifirPro", "the game", "we", "us") is a free multiplication practice game for children, families and anyone who wants to get faster at times tables. It is created by FOONE MANIKA / SPEKTRA and published at www.sifirpro.app.

We built SifirPro to be safe for children. It has no user accounts, no advertising, no purchases and no messaging between players. This policy explains, in plain language, exactly what information the game handles and what it does not.

When you play, the game stores the following in our hosted database:

• Nickname — a short display name you type in yourself. You choose it freely; it does not have to relate to your real identity.
• Country — chosen by you from a list, so leaderboards can be filtered by country. You may leave it as "Not specified".
• Age group — one of four broad ranges (6–8, 9–10, 11–12, 13+). This only sets the difficulty of the times tables you are given. We do not collect a date of birth or an exact age.
• Game results — for each completed run: score, number of correct and missed answers, accuracy, best streak, which times tables appeared, how long the run lasted, the game mode, the Daily Challenge date where relevant, and the date and time the run was saved.

Your nickname, country and age group are also saved in your own browser's local storage on your device, so you do not have to type them again next time. You can clear this at any time by clearing your browser data for this site.

Like any website, our hosting provider processes standard technical request information (such as IP address and browser user agent) in order to deliver pages and protect the service. We do not use this to build player profiles, and we do not run any analytics or tracking product.

Ordinary gameplay never asks for, and the game does not store:

• a real full name
• a school name or class name
• a home address or postal address
• precise or approximate device location (there is no GPS or location permission)
• a phone number, email address or password
• contacts, calendar or microphone access
• profile photos or any uploaded images or files
• payment or card details

There are no user accounts and no sign-in. You do not need to create an account, verify an email address or connect a social profile to play.

We use the information described in Section 2 only to:

• run the game and generate questions at a suitable difficulty;
• calculate your score, accuracy and streaks;
• show public leaderboards for today, this week, this month and all time;
• let leaderboards be filtered worldwide or by country;
• show you your own statistics and progress;
• operate the shared Daily Challenge fairly;
• keep the game working properly and prevent abuse of the leaderboards.

We do not sell, rent or trade personal information. We do not use it for advertising, profiling or marketing, and we do not create behavioural profiles of players.

SifirPro is designed for a family and school-age audience, and it is designed to protect children's privacy. We follow the applicable laws of the places where the game is available, and we make no claim of certification under any specific programme.

• The game deliberately asks for as little as possible: a made-up nickname, a country and a broad age group.
• Children are told, right where they type it, never to use their real full name and never to include personal details such as a school, address, phone number or email in a nickname.
• There is no chat, no messaging, no friend list and no way to contact other players.
• There is no advertising, no tracking and nothing to buy.

Parents and guardians are welcome to sit with their child while the player is created, and may request deletion of any record at any time (see Section 9).

When a run is saved, the following becomes publicly visible on our leaderboards:

• the nickname you chose;
• the country flag and code you chose (unless set to "Not specified");
• the score and accuracy of the run;
• how many games are counted in that leaderboard window, and the rank.

Nothing else is published. No school, no class, no age, no location beyond the country you picked, and no photo. Age group is used only for difficulty and to help us understand how the game is used; it is not shown on any public leaderboard.

Because nicknames are not reserved or verified, more than one player may use the same nickname. Please choose a nickname that does not identify you.

SifirPro is currently free and there is no payment processing of any kind in the game. There are no subscriptions, no in-app purchases, no advertising, no cash prizes and no real-money competition or gambling-style mechanics. We do not collect or store payment information.

If a paid feature is ever introduced in the future, this policy and the store listing will be updated to describe it clearly before it becomes available.

We keep outside services to the minimum needed to run the game:

• Lovable Cloud — hosts the website and the database where nicknames, countries, age groups and game results are stored.
• Google Fonts — delivers the game's display font. Your browser requests the font file from Google's servers when a page loads.

We do not use Firebase Analytics, AdMob or any other advertising network, Google Sign-In or other social login, PayPal, FPX, Stripe or any payment processor, and no analytics or attribution SDK.

Game results are kept so that leaderboards and personal statistics work over time. We keep them until they are no longer needed or until deletion is requested.

How to request deletion. A player, parent or guardian may ask us to delete records for a nickname. Please send the request through the support contact available at www.sifirpro.app and include the nickname and country shown on the leaderboard so we can find the right records. We will remove the matching records from the leaderboards and the database.

You can also remove the copy stored on your own device at any time by clearing your browser data for this site, or by changing your nickname, country or age group in the game.

Authorized support staff can delete records by nickname, country, age group, game mode, or all records at once.

Historical school records. Earlier versions of this game were used by a single school and stored a pupil's entered name together with a class label. Those older records are no longer used by the game, are not shown to players anywhere, and are visible only to authorized support staff. They may be deleted on request in the same way.

All traffic to the game is encrypted with HTTPS. Game results can only be written through a validated server function with server-side checks — the app on your device cannot write arbitrary data or declare its own score. Private management tools are password-protected, use a signed, encrypted, HTTP-only session cookie, and never expose private records to players.

No system can be guaranteed perfectly secure, but because the game holds so little information about players, the impact of any incident is deliberately kept small.

SifirPro is available worldwide and the English-language interface is the same everywhere. The website and database are operated through our hosting provider's infrastructure, which may be located in a country other than your own, so the limited information described in Section 2 may be processed outside your country of residence.

We may update this policy when the game changes. The effective date at the top will be updated, and material changes — particularly any change to what is collected, or the introduction of a paid feature — will be described here before they take effect.

For privacy questions, deletion requests or anything else about SifirPro: Multiplication Arcade, please use the support contact available at www.sifirpro.app. The game is published by FOONE MANIKA / SPEKTRA.
