Not legal advice This document is provided in good faith for transparency. It is not legal advice. Some jurisdictions do not allow certain exclusions or limitations of liability, so parts of the disclaimer below may not apply to you, and mandatory statutory rights are unaffected.

1. Privacy statement

1.1 The apps

All our apps are designed to work entirely on your own devices. The only exceptions are AI OS Controller when you choose a cloud AI, and ExperimentApps Installer, which downloads apps from this website (see below).

  • The apps do not collect usage data, analytics or telemetry, and contain no advertising or tracking libraries.
  • The apps do not request any personal data and have no accounts, sign-up or login with us.
  • The apps use no cookies.
  • The apps are free: no payment, no in-app purchases, no advertising.
  • Data an app needs (such as scripts, settings, saved games or high scores) is stored only in that app's private storage on your device and is never uploaded to us.

Per app:

  • ExperimentApps Installer connects only to experimentapps.com, over HTTPS, to read the list of apps and download the APK you choose; these are ordinary requests to this website (see 1.2). It sends no data about you or your device. It stores only its settings and the signing-certificate fingerprints of the apps it installed, in its private storage on your device; downloaded APKs are deleted after installation.
  • FileDeck is a file manager. It requests the Internet permission only to connect to the network locations (NAS, SFTP, FTP, WebDAV, SMB) you add yourself, and only while you browse them. Files go directly between your device and those servers; we never receive them. Saved locations, passwords, keys and trusted server identities are stored encrypted on your device. The optional "All files access" permission is only active when you turn it on. The app has no background activity.
  • Keystroke Sender does not request internet access and cannot transmit your scripts or any other data off your device. It only sends keystrokes to the computer you connect it to.
  • LED Ticker does not request internet access. It uses NFC and Bluetooth only to link phones that you tap together, and only while the app is on screen. Your settings and quick picks are stored only in its private storage on your device.
  • Light Editor requests no permissions and has no internet access, so it cannot transmit your text or files off your device. It only opens and saves the files you pick in Android's file picker. Its settings, list of recent files and an unsaved draft are stored only in its private storage on your device; a file you share is copied temporarily to its private cache for the app you choose.
  • Media Viewer does not request internet access and cannot transmit your photos, videos or any other data off your device. It only reads the folders you choose (or, if you turn on the optional "All files access", shows the folders you add). It keeps a list of your collections and small thumbnails in its private storage and cache on your device.
  • NetScope requests the Internet permission because Android requires it to open any network connection, including connections to devices on your local network. It only communicates with the hosts you enter and your network's own DNS server, and never contacts us or any cloud service. Tool results are kept in memory; only scans you save and your port list are stored in its private storage on your device.
  • NetWarden runs a local VPN on your device to record and filter the network traffic of your apps. That traffic is passed on directly to its destination and is never sent to us or to any server of ours. The traffic log, block list and settings are stored only in its private storage on your device, and only leave it when you export them yourself.
  • Off requests no permissions and has no internet access. It uses the device admin "lock the screen" ability that you activate yourself, only to lock your device when you tap it, and stores no data.
  • Offline Recorder does not request internet access and cannot transmit your recordings or transcripts off your device. It uses the microphone only while you record. Recordings and transcripts are stored in the folder you choose; speech recognition runs entirely on the device.
  • PDF Viewer requests no permissions and has no internet access, so it cannot transmit your documents off your device. It only opens the file another app sends to it. Word, Excel and PowerPoint files are converted to PDF on your device. The document is copied to its private cache only while it is open and deleted when you close it; the app stores no settings, history or recent files.
  • Pocket NAS requests the Internet permission because Android requires it to open any network port, including one that only listens on your local network. The app never connects to the internet itself and, by default, refuses connections from outside your local network. Files are transferred directly between your own devices; we never receive them. The login password you set is stored encrypted on your device, and the activity log is kept in memory only.
  • SFTP Studio runs a file server on your device and connects to servers you choose. Files are transferred directly between your own devices, or between your device and the server you connect to; we never receive them. By default, the server refuses connections from outside your local network. Settings, passwords, keys and the server identity are stored encrypted on your device, and the activity log is kept in memory only.
  • SyncDeck copies files between the folders and servers you choose, also in the background and on a schedule you set. Files go directly between those locations; we never receive them. Settings, saved locations, passwords and keys are stored encrypted on your device, and its sync history and logs are kept only in its private storage on your device.
  • Tag Actions reads NFC tags and runs the actions you link to them. It stores your tags and settings in its private storage on your device. Data only leaves your device through actions you set up yourself: a text message (for example with a location link) to the contact you choose, or a web request to the address you enter. Each permission is only requested when you use an action that needs it. The app never sends anything to us.
  • Tether connects only to the VNC and SSH computers you add yourself. Your screen, keystrokes, clipboard and files go directly between your device and those computers; we never receive them. Connections, templates, passwords and keys are stored encrypted on your device, and the connection log is kept in memory only.
  • AI OS Controller (Windows) sends nothing to us. When you choose a cloud AI (Google Gemini or Anthropic Claude), your questions and the output of the commands you approve are sent to that provider, using your own API key, and are processed under that provider's terms and privacy policy. By default, sensitive values such as IP addresses, user names, passwords and serial numbers are masked before sending; masking is pattern based and cannot guarantee that every personal detail is found. With a local Ollama model, nothing leaves your computer. Settings, encrypted API keys and chat logs are stored only on your computer.
  • Disk Toolkit (Windows) has no network functions and sends nothing to anyone. The index files, duplicate reports and delete scripts it creates contain file names, paths, sizes, dates and checksums of the folders you index, and are stored only where you save them and in its data folder on your computer, together with its settings and logs.
  • 2048, Chess Puzzles, FreeCell, Hex Marbles, Hitori, Mahjong, Make Ten, Marble Maze, Nonogram, Number Match, Solitaire, Spider Solitaire, Sudoku, Tilt Pop and TriPeaks request no permissions at all, have no internet access and work fully offline.

1.2 This website

This website sets no tracking or advertising cookies and does not profile visitors. Your browser may make standard requests to load the pages, and our hosting provider may process technical server log data (such as IP addresses) for security and to keep the site running, in line with their own policies.

1.3 The contact form

When you use the contact form, you voluntarily provide your email address, optionally your name, and your message. We use this information for one purpose only: to read and reply to your question. We do not use it for marketing, we do not add you to any mailing list, and we do not sell or share it with third parties for their own purposes. The message is delivered to us by email and retained only as long as reasonably needed to handle your request. You may ask us to delete your message and details at any time via the contact form.


2. Acceptable use

Our apps are general-purpose utilities and games, shared for learning and fun. By using them you agree that:

  • You will only use Keystroke Sender on computers, devices and systems that you own or are explicitly authorised to operate.
  • You will only share files with Pocket NAS that you are entitled to share, only on networks you trust, and that you are responsible for who you give access to.
  • You will only connect FileDeck, SFTP Studio and SyncDeck to servers and devices you own or are authorised to use, only share and copy files you are entitled to share, and you are responsible for who you give access to an SFTP Studio server.
  • You will only use NetScope to scan and analyse networks and devices that you own or are explicitly authorised to analyse.
  • You will only use Tag Actions to send messages, share a location or send web requests with the knowledge and consent of the people involved, and only to devices and services you own or are authorised to control. Any costs charged by your provider (for example for text messages) are your own.
  • You will only use Tether and AI OS Controller on computers that you own or are explicitly authorised to operate, and you will read every command before you approve it in AI OS Controller.
  • You will only index drives and delete files with Disk Toolkit that you own or are authorised to manage, and you will check the files you marked before you run a delete script.
  • You will only use NetWarden to monitor devices and traffic that you own or are authorised to examine.
  • You will only record people with Offline Recorder with their knowledge and consent, where the law requires it.
  • When you use a cloud AI in AI OS Controller, you comply with that provider's terms, and any costs charged by the provider for API use are your own.
  • You are solely responsible for complying with all applicable laws and regulations, workplace and organisational policies, and any third-party terms of service.
  • You will not use the apps for any unlawful, harmful, fraudulent or unauthorised purpose, or to gain access to systems or data without permission.

You are fully responsible for the scripts you create and run, the files and folders you share, copy, sync or delete, the networks you scan or monitor, the commands you approve, the delete scripts you run, the apps you install, and their effects on any system or data.


3. Disclaimer & limitation of liability

3.1 Provided "as is"

The apps and this website are provided "as is" and "as available", for learning and experimentation, without any warranty of any kind, whether express or implied. To the maximum extent permitted by applicable law, we disclaim all warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, reliability, and uninterrupted or error-free operation.

3.2 Use at your own risk

Your use of the apps is entirely at your own risk. Keystroke Sender sends keystrokes and mouse actions to other devices and can, if misused or through unexpected behaviour, cause unintended actions, disruption, data loss or damage on a target system. Pocket NAS reads, writes, renames and deletes files on the storage you share and makes it reachable over a network; errors, misconfiguration, hardware failure or interrupted transfers can lead to data loss or unintended access. Pocket NAS is not a backup solution. FileDeck, Media Viewer, SFTP Studio and SyncDeck can copy, move, overwrite and permanently delete files on your device and on connected drives and servers; SyncDeck deletes files in a destination when they are deleted at the source in the Echo and Synchronize modes, and a synced copy is no guarantee that your data can be recovered. SFTP Studio makes the folders you share reachable over a network. NetScope sends network probes, such as pings and port scans, which can trigger security systems or be against the rules of a network you do not manage. Tag Actions changes settings on your device and can send text messages and web requests; a misconfigured tag can, for example, silence your alarms, send a message you didn't intend, or switch a connected device. Tether gives full control over the computers you connect to; commands and key combinations you send take effect immediately. AI OS Controller runs commands suggested by an AI, which can be wrong; its risk check is a heuristic safety net, not a sandbox, and an approved command can change settings, stop services or delete data. NetWarden can block network traffic, which can stop other apps (including messaging or emergency-related apps) from working. Light Editor overwrites the original file when you save, and changes to configuration files or scripts take effect wherever those files are used. Disk Toolkit reports files as duplicates based on the criteria you choose, which does not guarantee that they are identical, and its delete scripts permanently delete files unless you use the Recycle Bin option. PDF Viewer shows converted Office files as a preview that can differ from the original. ExperimentApps Installer installs, updates and uninstalls apps on your device after your confirmation; turning off its development checks weakens the protection against tampered files. Off relies on your device to lock it; whether biometrics are disabled for the next unlock depends on your device. LED Ticker can show bright, flashing effects that may affect people with photosensitivity. Transcripts made by Offline Recorder can contain errors. You are responsible for taking suitable precautions, such as testing safely, using strong passwords and backing up important data.

3.3 Limitation of liability

To the maximum extent permitted by applicable law, ExperimentApps and anyone involved in creating or distributing the apps shall not be liable for any direct, indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits, revenue, goodwill or business, arising out of or in connection with your use of, or inability to use, the apps or this website — even if advised of the possibility of such damages.

To the extent liability cannot lawfully be excluded, it shall be limited to the greatest extent permitted by law. Nothing in this disclaimer excludes or limits any liability that cannot be excluded or limited under applicable law — for example, in some jurisdictions, liability for intent or gross negligence, or for death or personal injury caused by negligence. Because the apps are provided free of charge, no refund or monetary remedy is available.

3.4 No claims against the developers

By downloading, installing or using any of the apps you acknowledge and agree that you use it on your own responsibility and at your own risk, and, to the maximum extent permitted by applicable law, you waive any claim against the developers of ExperimentApps arising from their use. You further agree to hold the developers harmless from any third-party claim resulting from your use of the apps, the scripts you run, the files you share or sync, the networks you scan or monitor, or the commands you approve.

3.5 Third-party hardware and software

The apps work together with third-party hardware (such as CH9329 adapters, InputStick dongles, USB drives, hubs, routers, NAS devices, NFC tags, Bluetooth devices and smart-home devices), third-party software and services (such as WebDAV, SFTP, FTP and SMB servers and clients, VNC and SSH servers, AI services such as Google Gemini, Anthropic Claude and Ollama, the .NET runtime, Vosk speech models, web hosting providers, web browsers, VPN services and smart-home platforms) and third-party operating systems. We are not affiliated with, and make no warranties about, any of these products, and we are not responsible for their availability, behaviour, quality or safety.

3.6 Availability & changes

We may change, suspend or discontinue any of the apps, this website, or any feature or download at any time, without notice or liability. We may also update this document from time to time; the current version always applies.


4. Governing law

These terms and any dispute arising from the use of the apps or this website are governed by the laws of the Netherlands, without prejudice to any mandatory consumer-protection rights you may have in your country of residence.
