Privacy policy

Last updated: 15 November 2026 · Applies to Arlequin GameHub (including SaveHub, its save backup part) · This is a translation of the Spanish version, which prevails in case of doubt.

1. Who is responsible

Arlequin GameHub is a free program developed by aitor965 (Arlequin). SaveHub, the part that backs up and restores your saves, is included inside GameHub; the former standalone Arlequin SaveHub program is no longer distributed. For any privacy question you can write to arlequinsavehub@gmail.com.

2. Data handled on your computer

To do its job, GameHub reads and stores on your PC:

• The list of installed games reported by your launchers (Steam, Epic, GOG, etc.), their folders and your hours played.
• The save folders and, in games that use them, the Windows registry HKEY_CURRENT_USER keys where they keep the save.
• SaveHub's backups, in the folder you choose.
• Each game's graphics settings files (and, in Unity games, their registry keys), to show them on its page and, only if you ask with “Save”, change them. Before the first change a copy of the original is kept in GameHub's data folder, so it can go back to how it was.
• If you install GameHub's sensor service: while you play, which folders, files and registry keys the game itself writes (only their names, never their contents), to know where it keeps its saves and settings. It doesn't look at other programs or at other users of the computer.
• The images you choose as a game's cover, copied into GameHub's data folder.
• Your computer's specifications (section 3.2), for the Runs on my PC filter and the Your PC section.
• Settings, caches and logs, in GameHub's data folder (%APPDATA%\com.arlequin.gamehub; it opens from Options → Privacy and data → Your data).

None of this is sent to the developer or to any project server, except what's described in section 3 if you have Help improve Arlequin turned on.

2.1 Internet connections

Some features talk only to programs on your own PC, without going over the internet: the Discord status (shows your Discord friends "Arlequin GameHub" and the game you're playing; it's turned off in Options → When playing) and TeamSpeak (reads the server, channel and messages of the TeamSpeak you already have open).

The HUD also talks only to your PC: it reads Windows performance counters and, if you have them open, the sensors shared by HWiNFO (shared memory), LibreHardwareMonitor (its web server on your own computer, 127.0.0.1:8085) or MSI Afterburner (shared memory). Those readings are only used to show them on screen and for the graphics card connector warning: they're not stored or sent. The HUD, the crosshair and their settings are stored in GameHub's data folder.

3. Help improve Arlequin (optional)

You're asked at the end of the welcome window, with a Yes or a No (nothing is chosen in advance), and you can turn it on or off whenever you want in Options → Privacy and data. Nothing is sent before you've seen that window. On that same page you can choose one by one what you share (section 3.3).

3.1 Save paths

GameHub anonymously sends what it has learned and Arlequin's database doesn't know yet, to compare it with what other computers send and expand that database:

• Learned paths: the save folders you add by hand, the ones GameHub finds for games with no known path and the ones it sees the game itself write. They're sent as templates with placeholders (for example <winDocuments>/My Games/Game), never with your username or your computer's own folders; if a path can't be anonymised, it isn't sent.
• Games without a path: the name, store and store ID of installed games the database doesn't know or has no save path for.
• Where it keeps its settings: the settings folders and the HKEY_CURRENT_USER\Software keys where the game keeps its settings (only the folder name, as a template, or the key name, never their contents; if they contain your username or an account number, they aren't sent).
• What is inside each new path: the first time your installation sends a path, also an anonymous list of what it contains (at most 2 levels and 30 entries): the names of files and folders, with numbers and long codes replaced by # and words that are not technical or from the game replaced by * (for example, Pepe's save.sav is sent as *.sav), and their rounded size. Never the content of the files, your user name or your Steam account. It helps tell which files are saves, which are settings and which do not need to be copied.
• What you remove: the folders or keys you say don't belong to a game or that you don't want to back up, to check whether they should be removed from the database.
• Game servers you type in: if in a game with servers (such as Dofus) you choose “Other” and type a server the list does not have, the name of the game and of the server are sent once, to add it to the list. Nothing else.
• The GameHub version and a random installation identifier, used only to count how many different computers confirm the same data. It isn't linked to your name or your account. Each submission also carries this computer's ID (a short code taken from your PC's Windows identifier, impossible to turn back into the original), so that submissions from the same PC can be joined together if you reinstall GameHub.

The content of a save is never sent. It's sent at most once an hour and only if there's something new.

Game catalogue: to recognise games on other computers (for example, one installed in a folder where its store didn't record it), GameHub also sends the name, store, store ID, install folder name and executable name of the games in your stores, installed or not. It goes separately from the rest: each submission carries a new random identifier, not your installation's. It is only sent if you have the “Save and settings paths” metric turned on. Only what the database doesn't have yet and hasn't been sent before is sent, at most every 5 days or when you click Refresh, and never with a game open. Even so, it is not entirely anonymous: it leaves from your own connection (the server sees your IP address, as with any submission) and a full list of games can end up identifying a person. That is why it carries neither your installation identifier nor this computer's ID, and it is sent at a random time, between 10 minutes and 2 hours later, not right after the normal submission.

Console games (EmuHub): for the console games in EmuHub that GameHub recognises by their serial number or fingerprint and that have an official name, the console, serial number (or fingerprint), region and official name are also sent. Never the path or the file name, nor save folders or FPS.

Steam games on your account: Steam keeps on the PC the games of every account that has signed in on it and those of your Steam Family, without saying whose they are. To tell them apart, GameHub sends the SteamID of the active Steam account to my service (Google Apps Script), which asks Steam which games that account has and returns only the list of game numbers. Neither the SteamID nor the response is stored anywhere of mine; your GameHub keeps the list on your PC for one day. It only works if game details are public on your Steam profile.

Games found while you play: if you open a program that isn't in your library and looks like a game, GameHub recognises it on your computer (by its executable or its folder) or asks you whether it is one when you close it. That happens only on your PC; if you add it, it's treated like any other game in your library.

3.2 Your computer's hardware and FPS

GameHub looks at your computer's specifications for the Runs on my PC filter, which compares your computer with each game's minimum and recommended requirements (the Steam store's). The comparison is done on your computer. With Help improve Arlequin turned on, this data is also sent anonymously, to build hardware statistics of players:

• CPU: brand, model, cores and threads.
• Graphics card: brand, model, who made the card (Sapphire, ASUS...) and its model code, memory and, on NVIDIA cards, the power limit in watts.
• RAM: amount, type (DDR4, DDR5...), speed, number of modules, brand, module model and its factory CL latency.
• Operating system and its version.
• Drives: how many of each type there are (NVMe, SSD, hard drive) and their total capacity, and the brand, model and size of each one (for example “Samsung 990 PRO 2 TB”). Never their content or serial number.
• Type of computer (desktop, laptop or Steam Deck).
• Screens: resolution, refresh rate, brand and model, size in inches, which is the main one and the panel type if you set it (OLED, IPS, VA...).
• Peripherals: the model name your keyboard and mouse report to Windows (for example "Razer Basilisk V3"), and the brand and model of the controllers and wireless headsets (Bluetooth or USB receiver) that have been connected to that PC (for example "DualSense" or "SteelSeries Arctis 7"). Never their serial number.
• Internet connection: whether it's wired or Wi-Fi, the link speed and the result of a speed test (download, upload and ping) against Cloudflare's servers (speed.cloudflare.com). The test takes about 25 seconds (several connections at once, to measure fast connections properly) and is never run with a game open: 5 minutes after opening GameHub if the last one is more than 30 days old, or with the button in Options → Your PC.
• Country, according to Windows' regional settings (never from your IP address or your location).
• Virtual memory (Windows page file): how much there is and whether Windows manages it.
• Motherboard: brand and model, and its BIOS version and date (never its serial number).
• Whether GameHub was installed from the Microsoft Store or from this website.

Your sessions' FPS (separately optional): if you also turn on Measure FPS while you play (Options → Your PC), GameHub uses PresentMon, a free tool from Intel, to know how often the game draws a frame, without touching the game. When you close the game a summary of the session is stored on your computer and, with Help improve Arlequin turned on, it's sent: the game (name, store and store ID), the day, the minutes measured, average FPS, the median, the 1% low, stutters, what was limiting (the GPU or the CPU), the peak RAM, graphics memory and virtual memory used during the session, how many hardware errors Windows corrected while playing (WHEA: CPU, RAM or PCIe) and how many times the graphics driver hung and Windows recovered it, whether you were streaming with ReplayHub, the screen it was played on, the game's graphics settings (quality, resolution, upscaling, frame generation, ray tracing, VSync and FPS limit) and the CPU, graphics card and memory model it was played with. It's used to work out how many FPS each game gets depending on the hardware and whether they came from an unstable overclock.

The computer name, your username, serial numbers and any other hardware identifier are not sent. Hardware is sent the first time and then at most every 30 days (or when you click Refresh, if something has changed), and a single row is kept per installation, which is replaced if you change components.

3.3 Each metric separately

In Options → Privacy and data you can choose what you share: save and settings paths, hardware, screens, peripherals (keyboard, mouse, controllers and headsets), internet, country, sessions with FPS, BenchHub and AimHub. What you don't share isn't sent. You still see your own data in GameHub the same way (Your PC, your FPS and the "Runs on my PC" filter). What's worked out from community data (for example, FPS estimates with other players' sessions, comparisons or statistics) is only shown to those who share that same metric or have ArlequinPro.

3.4 Where it's stored and what it's used for

Submissions are stored in private files in the project's Drive (Google Apps Script) and in a private project database on Supabase (servers in the European Union, Ireland), read only by the developer. Only aggregated data, without identifiers, reaches the public repository: paths confirmed by several computers, hardware percentages (contribuciones/HARDWARE.md) and FPS medians grouped by game, graphics card, resolution and quality (contribuciones/FPS.md), never individual sessions. For the Statistics filters, the public database also carries an anonymous list of computers with the same grouped values (for example "32 GB", "27"", "600-1000 Mb/s"): without identifiers or country, sorted by content (not by computer) and with each value as it is, even if only one computer has it (they're hardware specifications that don't identify anyone); GameHub doesn't show the result of filters that leave fewer than 3 computers. This data is used in Arlequin's databases and products, current or future, including paid ones. Personal data is never sold or transferred.

You can turn the option off at any time and ask for your submissions to be deleted by writing to arlequinsavehub@gmail.com; to identify them, give the installation identifier found in contribuir.json, inside GameHub's data folder.

3.5 BenchHub and BenchLab (Hall of Fame)

BenchHub and BenchLab are GameHub's performance tests. If you share BenchHub in Options → Privacy and data, your clean BenchHub tests and your best BenchLab test are sent, only when they beat the ones you already sent: the results of each test (points, FPS, speeds, latencies, temperatures, power, measured MHz, the hardware errors Windows corrected during the test, WHEA, and the times the graphics driver hung), the parts it ran on (processor, graphics card, memory and motherboard model, its BIOS version, amount of RAM, whether it's a laptop and whether the test ran on Windows or Linux), the settings GameHub records on its own (power limits, voltages, clocks and RAM timings, graphics driver version and Windows options that affect performance, and whether the motherboard fans were on automatic or at what percentage) and the nickname you choose, which is optional (without one you show up as "Anonymous").

This is used to publish the Hall of Fame in the public database and on this website: each PC's best test, with its nickname, parts, results and settings, without any computer or installation identifier. Tests that don't add up (impossible or run with errors) are not published. You can change or remove your nickname at any time (it changes on all your tests) and ask for your tests to be deleted like any other submission.

3.5.1 AimHub (Hall of Fame)

AimHub is the part of GameHub for warming up your aim; your runs are saved on your PC. If you share AimHub in Options → Privacy and data (with Help improve Arlequin turned on):

• When a run starts, GameHub asks Supabase for a run ticket: a number with the server's time and a signature, to check later that the run lasted as long as it says. Only the chosen mode and length are sent, and Supabase doesn't store anything per run.
• When it ends, if it's your best run in that mode and length, it sends: the mode, the length, the date, the results (score, hits, shots, accuracy, time on target or reaction times), the time for each target (in Tracking, the percentage of each second), whether the mouse had no acceleration, the ticket and your BenchHub nickname if you have one. The times are used to detect programs that aim by themselves.
• If you leave Share my setup ticked (ticked by default; you can untick it in AimHub), also: the game whose sensitivity you use and its value, the cm per turn, your mouse DPI, the vertical sensitivity, the field of view, your screen’s Hz (measured during the game) and your crosshair design (shape, colours and sizes, without its name).

The developer reviews runs before publishing them, so they take a while to appear. The AimHub Hall of Fame is published on Supabase, where GameHub reads it: each PC's best run in each mode and length, with its nickname, results, date and setup if shared (other users can copy it into their GameHub), and the list of scores without names so everyone can see their rank. Never a computer or installation identifier. Runs that don't add up aren't published. You can ask for your runs to be deleted like any other submission.

3.6 Tester codes

If you ask for a test code, GameHub creates a request file with this computer's ID: a short code worked out from the motherboard's network card (for older codes, from the Windows installation identifier), from which the original can't be recovered. That way the code keeps working if you reformat or change operating system. The request also includes fingerprints of your accounts (the Steam accounts that have signed in on that PC, up to 5, even if they belong to someone else in your home, and the Microsoft account you sign in to Windows with) and of your hardware (the processor, graphics card, motherboard, BIOS, RAM, drives, screen, mouse and keyboard models; never serial numbers): each one is a short code from which the account or the part can't be recovered, and it's only used for comparing. With them the code keeps working if you change your network card, as long as one of your accounts and your hardware match at the same time. It's only sent if you send that file yourself, and it's used so the code doesn't work on another PC. The code is checked without internet; GameHub only downloads the public list of revoked codes. If you have a code entered and Help improve Arlequin is on, submissions include a fingerprint of that code (not the code itself: it can't activate anything), to know which codes are still in use and to group the same PC as a single computer when its ID changes (for example, after reformatting); it's included even if the code no longer works on that PC.

Some gift PRO codes are tied to the first PC that activates them. When you activate one of these, and then once a day, GameHub sends Supabase (servers in the European Union) a fingerprint of the code (not the code) and the IDs of this computer described above, to tie it to your PC so it doesn't work on another one. It can't be activated without internet. Only that fingerprint, those IDs and the dates of activation and of the last check are stored.

3.7 Crash reports

With Help improve Arlequin turned on, if GameHub crashes a technical report is sent so it can be fixed:

• the error message and where in GameHub’s code it happened (a list of positions inside the program);
• which section of GameHub you had open (for example, Library or Options), whether it was in POTATO mode or running a BenchHub test, and how many minutes it had been open;
• the program’s last internal actions before the crash, such as “window opened” or “game closed”. They are fixed GameHub phrases, with no game names and nothing you have typed;
• the GameHub version, the Windows version, the date and the random installation identifier.

No screenshots are taken, and nothing you see, type or have on your PC is sent. Before sending it, your user folder and user name are removed from the text. If the option is off, crashes stay on your PC (20 at most) and are not sent.

3.8 Suggestions and problems

In Options → Privacy and data you can write a suggestion or a problem to the developer. It is sent right away, even with Help improve Arlequin turned off, because you send it yourself: the text you write, whether it is a suggestion or a problem, the language, the GameHub version and the random installation identifier. If you want a reply you can add your email or Discord (optional): it is only used to answer you. You can ask for it to be deleted by writing to arlequinsavehub@gmail.com.

3.9 Uninstall survey

When you uninstall GameHub, the uninstaller may ask why you are leaving. It is optional: if you do not choose a reason, nothing is sent. If you choose one, it sends the reason, the text you write (optional, up to 500 characters), the language, the GameHub version, the random installation identifier and the device identifier. It is only used to improve GameHub and to know which devices no longer have it. The device identifier is only included if Help improve Arlequin was turned on.

4. Use of Google data (Google Drive)

Connecting the cloud is optional and is done in SaveHub → Cloud. GameHub uses the registered application Arlequin SaveHub for this, which is the name you'll see on Google's, Microsoft's and Dropbox's permissions screen. With Google Drive it requests the permission https://www.googleapis.com/auth/drive.file, which only gives access to the files and folders created by the application itself (the Arlequin GameHub folder in your Drive). It can't see or change the rest of your Google Drive.

• Storage: the access token is stored only on your PC, in nube.json inside GameHub's data folder. It isn't sent to the developer or to third parties.
• No sharing or selling: Google data is not shared, sold or transferred to anyone, is not used for advertising and is not used to train artificial intelligence models. A clip is only shared if you upload it, and with whoever has its link.
• No human access: nobody on the project has access to your account, your files or your token.

Only one cloud can be connected at a time. To change clouds, disconnect the current one in SaveHub → Cloud. For clips you can connect a separate cloud, in the ReplayHub clip settings. On OneDrive and Dropbox clips are saved in the application folder, with no link.

5. Use of Microsoft data (OneDrive)

If you connect OneDrive, GameHub signs in with the Microsoft identity platform and requests these permissions:

The access token is stored only on your PC (nube.json). You can revoke access at account.live.com/consent/Manage (personal accounts) or from your organisation's portal (work or school accounts).

6. Use of Dropbox data

The application is registered with Dropbox with “App folder” access: it can only use the Apps/Arlequin SaveHub folder in your Dropbox (GameHub uses the GameHub subfolder) and can't see or change the rest of your files.

The access token is stored only on your PC (nube.json). You can revoke access at dropbox.com/account/connected_apps.

As with Google: Microsoft and Dropbox data is not shared, sold or transferred to anyone, is not used for advertising or to train artificial intelligence models, and nobody on the project has access to your account, your files or your tokens.

Backup of your options and play history

With any of the three clouds connected, GameHub also stores in its folder configuracion.json (your options, including each game’s launch options, its graphics profiles and settings, LootHub and SocialHub) and historial.json (what you have played: hours, AimHub and BenchHub), so you can recover them on another PC or after reinstalling. These files are only in your cloud: the developer has no access to them.

7. How to withdraw access and delete your data

• In GameHub, SaveHub → Cloud → Disconnect: deletes the token from your PC.
• You can revoke access at any time: Google at myaccount.google.com/permissions, Microsoft at account.live.com/consent/Manage and Dropbox at dropbox.com/account/connected_apps.
• The backups you uploaded stay in your cloud until you delete them.
• To delete all local data, uninstall GameHub, delete its data folder (%APPDATA%\com.arlequin.gamehub) and your backup folder.
• To delete what you've shared with Help improve Arlequin, follow section 3.4.

8. This website

arlequinsavehub.com is a static information website: it doesn't use cookies, forms or analytics. It only remembers in your browser the language you choose in the language selector. The hosting provider (Cloudflare) may log technical access data, such as the IP address, under its own terms. In addition, the pages load the font from Google Fonts (Google can see your IP address), the home page and the Hall of Fame read public figures from Supabase, and the Hall of Fame and Statistics load the sql.js library from cdnjs (Cloudflare), also under their own terms.

9. Minors

GameHub isn't specifically aimed at minors and doesn't collect anyone's personal data. The use of Google Drive, OneDrive, Dropbox, Discord and Steam is subject to each service's age requirements.

10. Changes to this policy

If this policy changes, it will be published here with a new update date and mentioned in the release notes of the corresponding version.
