Privacy Policy
This policy describes how LFT Inc. handles information across its apps and this website. App-specific notes appear at the bottom of this page (or on each app's detail page).
Principles
LFT Inc. (“LFT,” “we,” “us”) respects your privacy across every app and service we ship (collectively, the “Services”). The Services are designed to use the minimum information necessary to provide their features, and to keep data on your device whenever possible.
Information we use
We collect only the minimum information needed to provide a feature. Most apps do not transmit any personally identifiable information to our servers. Where data is stored, it lives in one of the following:
- Your device’s local storage (each app’s sandbox)
- Platform-provided cloud services you opt into (Apple HealthKit, iCloud, Game Center, Google Play Games Services, etc.)
The specific types of information each app uses (camera, photos, health data, advertising identifiers, device identifiers, etc.) depend on the app’s nature. See “Per-app notes” at the bottom of this page for details.
Storage and transmission
- On-device storage: Each app’s data (settings, history, scores, analysis results, etc.) is stored only in the app’s local sandbox on your device.
- Platform services: When an app uses HealthKit, iCloud, Game Center, or Google Play Games Services, that data is governed by the respective platform’s privacy policy.
- Our servers: We do not operate our own analytics or tracking servers. The only data we receive on servers we control is what you submit through the contact form on this website.
Some apps communicate with third-party services to deliver their features (advertising networks, AI model distribution, external store links, etc.). See “Per-app notes” for specifics.
Sharing with third parties
We do not share your personal information with third parties except:
- With your consent
- Where required by law
- Where necessary to protect a person’s life, body, or property and consent cannot reasonably be obtained
When an app communicates with a third-party service, that data is governed by the respective service’s privacy policy.
Permissions
Each app requests OS-level permissions (camera, photos, HealthKit, notifications, location, etc.) only at the moment a feature requires them. You can change or revoke permissions at any time from your device’s Settings. If you decline, the affected feature will be unavailable.
Deleting data
- Where an app offers in-app controls to delete specific data, please use those.
- Removing the app from your device deletes all of that app’s local data.
- Data stored on platform services (HealthKit / Game Center / Google Play Games Services etc.) must be deleted from the corresponding platform app.
Cookies and tracking
This website (lft-farm.com) stores display preferences (your dark-mode state and your cookie-consent choice) in your browser’s storage (localStorage) rather than in cookies. This information is not sent to our servers and is not used to identify you personally. We do not set any first-party cookies of our own for these purposes; cookies are used only by the analytics described below, and only if you have consented.
Analytics (Google Analytics 4)
To understand how the site is used and to improve our content, this website uses Google Analytics 4 (GA4), an analytics service provided by Google LLC.
- Information collected: pages viewed (page views), referrer information (the linking site, search keywords, etc.), browser / OS / device type, screen size, an approximate location (country / region level) derived from your IP address, and on-site navigation and engagement. GA4 is designed not to store IP addresses, and we cannot identify any specific individual from this data.
- Purpose: analyzing traffic trends, improving content and page navigation, and detecting issues.
- Where data is sent: Google LLC (USA). The handling of collected data is governed by Google’s Privacy Policy and How Google uses information from sites or apps that use its services.
- Consent (Consent Mode): This site uses Google Consent Mode v2, and analytics cookies are disabled (denied) by default. Standard, cookie-based analytics (using a persistent identifier) becomes active only if you choose “Accept” in the consent banner shown on your first visit. If you choose “Reject,” or while you have not chosen, no analytics cookies or persistent identifiers are used and you are not tracked across visits. Even in this state, however, Google may receive cookieless, anonymous signals (minimal, non-identifying information used for aggregate estimation). Your choice is stored in your browser and persists until you clear your browser data.
- How to opt out: Choosing “Reject” in the consent banner stops cookie-based analytics. To stop GA4 analytics data being sent to Google altogether, install the Google Analytics Opt-out Browser Add-on or block requests to
googletagmanager.comandgoogle-analytics.com(where measurement data is sent) — for example, with a browser extension.
We do not serve ads, and we do not use advertising or ad-targeting tracking cookies.
Children’s privacy
The Services are not primarily directed at children under 13 (or the equivalent age set by your jurisdiction). For apps that have been rated as family-friendly or educational by the app stores, those store-level age ratings apply.
Changes to this policy
We may update this policy in response to changes in law or services. Material changes will be announced on this page or in the affected app. The updated policy takes effect when posted on this page.
Governing law
This policy is governed by the laws of Japan. The Japanese-language version is authoritative; other-language versions are provided for reference. In case of any conflict, the Japanese version prevails.

Per-app notes
Each app may collect or use different information depending on its features. The following sections describe per-app specifics that supplement the common policy above.
10-Year Diary
Open app detail →Diary data (stored on-device)
Everything you record—diary text, attached photos (up to 3 per entry on the free plan), weather, mood, star ratings, custom numeric status, and automatically recorded location—is stored locally on your device and encrypted on-device. This data is never sent to our servers. You can protect your data with Face ID / Touch ID authentication and a password lock.
On-device AI
AI features such as emotion-based auto star rating and text summarization all run on-device (Apple Foundation Models / Google Gemma 4 / Shisa.AI). Your diary content and the AI analysis results are never transmitted externally.
Location
The app can automatically record location with your diary entries. Recorded location is stored on your device and is not sent externally.
Advertising & Premium plan
The free plan delivers Meta Audience Network banner ads through Unity LevelPlay bidding and mediation. The Premium plan (paid subscription) removes ads.
For ad delivery, measurement and fraud prevention, the ad SDKs may collect advertising identifiers, device information, ad impressions and interactions, product interactions, diagnostics and performance data. Advertising identifiers and ad data may be used for tracking across other companies’ apps and websites. On iOS, tracking occurs only with permission through App Tracking Transparency (ATT). Product interaction and performance data are declared not to be used for tracking. See the store privacy disclosures for purposes and data linkage.
Exporting & deleting data
You can export your diary data as a PDF. Deleting the app removes all data stored locally.
ClearSpace
Open app detail →We collect no data
ClearSpace does not collect, store on our servers, transmit, sell, or share any personal data or usage data. The app has no analytics, no tracking, and no third-party data-collection SDKs.
Everything happens on your Mac
- All scanning, analysis, and cleanup happen locally on your device. File contents, file names, paths, and scan results never leave your Mac.
- The app runs in the macOS App Sandbox and accesses files only to find and remove reclaimable disk space. Which locations are read depends on the cleanup categories you enable, and can include system and user caches and logs; temporary files; the Trash (including the iCloud Drive Trash); the Downloads, Desktop, and Documents folders and your Photos library; installed apps in
/Applications; your~/Libraryfolders; your Home folder (for the "large old files" and "system junk" categories); and any folders you explicitly add as Custom Rules. In these locations the app does not read file contents; it works only with the file metadata (names, paths, sizes, and dates) needed to identify reclaimable space. - The scan cache and cleanup history (which include the paths and sizes of affected files) are stored only on your Mac. Any CSV export you explicitly trigger is also saved as a file on your Mac. The app never transmits any of this information.
- Deletions go to the Trash, not permanent deletion, so files remain recoverable.
- Folders you add as Custom Rules are stored on your Mac as macOS security-scoped bookmarks and are used only to re-access those folders on your device.
- Your settings and preferences (selected categories, schedule, cleanup mode, language) are stored locally on your Mac and are not shared.
Required-reason API usage
To show disk usage and identify cleanup candidates, the app uses Apple "required-reason" APIs solely on-device: disk space (to display storage), file timestamps (to display file dates, filter old/large files, and keep the scan cache current), and user defaults (to store your settings). These are used only for the app's stated functionality and are never used for tracking.
Children
ClearSpace is a general-purpose utility and is not directed at children. It collects no data from anyone, including children.
Dine & Wine
Open app detail →Camera & photo library
The app requests access to your camera and photo library so you can take or select photos of your food. Captured or selected photos are processed only on your device and are never sent to an external server.
AI processing
The app's AI features (dish recognition and wine-pairing suggestions) all run on-device. Photo data and AI analysis results are never transmitted externally.
AI model download
The first time you use the app, an AI model file (Gemma 4, provided by Google LLC) is downloaded via Hugging Face, which involves internet communication. During the download, your IP address and communication metadata are sent to Hugging Face. Hugging Face's handling of data follows its own privacy policy (https://huggingface.co/privacy). No other personal information is transmitted.
Local data
The following data is stored locally on your device. The developer does not have access to it.
- Analysis history (thumbnails of food photos, analysis results, timestamps) — up to the 50 most recent entries
- AI model files
- App settings
You can delete the analysis history and AI model files individually from the app's settings screen.
Shopping links
The app provides links to Amazon, Rakuten Ichiba, and Yahoo! Shopping as a reference for purchasing wine. These links contain affiliate IDs. The handling of data on the linked services follows each service's own privacy policy.
Third-party services
The app's main features (AI analysis and wine-pairing suggestions) are completed entirely on-device, but communication with third-party services occurs in the following cases.
- Hugging Face (when downloading the AI model): your IP address is sent
- Amazon / Rakuten Ichiba / Yahoo! Shopping (when you tap a shopping link): an external browser opens and each service's terms apply
Neon Nexus
Open app detail →Advertising information
The iOS app delivers banner ads from Meta Audience Network and ironSource Ads through Unity LevelPlay bidding and mediation.
For ad delivery, measurement and fraud prevention, the ad SDKs may collect advertising identifiers, device information, ad impressions and interactions, product interactions, diagnostics and performance data. Advertising identifiers and ad data may be used for tracking across other companies’ apps and websites. On iOS, tracking occurs only with permission through App Tracking Transparency (ATT). Product interaction and performance data are declared not to be used for tracking. See the store privacy disclosures for purposes and data linkage.
Android version 1.0.2 distributed on Google Play still includes the Google Mobile Ads (AdMob) SDK. A stop in ad delivery does not remove the SDK, which may collect advertising identifiers, device information and ad interaction data. This version requests non-personalized ads. See Google’s privacy policy.
Leaderboards
The app provides leaderboard features using Game Center (iOS) and Google Play Games Services (Android). Leaderboard score data is managed through each platform's services.
Game data
Your game progress and scores are stored locally on your device. The developer does not have access to this data.
Third-party services
To the extent necessary to provide the advertising and leaderboard features above, information is sent to the following third-party services.
- Google LLC (AdMob: Android, Google Play Games Services)
- Meta Platforms, Inc. (Meta Audience Network: iOS)
- Unity (Unity LevelPlay / ironSource Ads: iOS)
- Apple Inc. (Game Center)
We do not provide personal information to any third parties other than these.
Speed Test Reflexes
Open app detail →Measurement data
Your reflex measurement results (scores for each mode) are stored on your device. The app does not collect personally identifiable information such as your name or email address.
Rankings (Game Center / Google Play Games)
If you are signed in to Game Center (iOS version) or Google Play Games (Android version), your best score in Measure mode (single attempt) is submitted automatically for the world ranking. This data is handled in accordance with each platform's policy (Apple: https://www.apple.com/legal/privacy/ / Google: https://policies.google.com/privacy). If you are not signed in, your scores are never sent externally.
Advertising (Meta Audience Network / Unity LevelPlay)
The free version displays Meta Audience Network banner ads. From version 3.0.2, ad delivery uses Unity LevelPlay bidding and mediation. For ad delivery, measurement, fraud prevention and ad quality analysis, the SDKs may collect advertising identifiers, device information, ad impressions and interactions, and diagnostic and performance information. On Android, LevelPlay also collects and shares approximate location derived from information such as the IP address. The app does not request permission to obtain your precise location.
Advertising identifiers and ad data may be linked to device identifiers and used for tracking across other companies’ apps or websites. On iOS, tracking requires your permission through App Tracking Transparency. Product interaction and performance data are declared as used for advertising and analytics, without cross-company tracking. Refer to each store’s privacy or Data Safety disclosures for the data collected or shared and its purposes.
The recipients and handling of this data are subject to Meta’s privacy policy and Unity’s privacy policy. You can permanently remove ads through a one-time in-app purchase; when the purchase is recognized, the app does not initialize the advertising SDKs. Local storage of measurement scores and the optional Game Center / Google Play Games ranking remain as described above.
Squid Shooting
Open app detail →In builds where advertising is enabled, this app (Squid Shooting) uses the Google Mobile Ads SDK. In that case, device identifiers, usage data, and approximate location may be collected and shared by ad providers for ad delivery, measurement, and fraud prevention. Builds without an ad unit ID configured do not display ads.
Game play data (progress, scores, and the like) is stored on your device and is never sent to LFT's servers. Only when you use Game Center are scores and similar data handled through Apple's Game Center (use is optional).
Ojisan Match
Open app detail →On-device trivia generation
The "today's anniversary" trivia that Ojisan Match shows after each game is generated entirely on-device using Apple Intelligence (FoundationModels). The inputs used for generation, and the generated results, are never transmitted to external servers.
Information collected for advertising
This app is offered for free and displays ads via Google AdMob. When the consent prompt is shown at launch and when ads are displayed, communication occurs through the UMP (User Messaging Platform), and the following information may be collected through AdMob. None of this information is linked to your identity, and none of it is used for tracking (App Tracking Transparency): this app does not adopt ATT and does not perform cross-site / cross-app tracking via the IDFA.
- Identifiers (device ID, etc.) — for third-party advertising
- Usage data (ad interactions, product interactions) — for third-party advertising
- Location (coarse, IP-based) — for third-party advertising
- Diagnostics (performance, crashes, etc.) — for analytics
Collected data is handled in accordance with the respective privacy policies of Google and the UMP. You can change your advertising consent settings at any time from within the app or in your device settings.
MyPiece
Open app detail →LFT FARM ("we") sets out below how user information is handled in the iOS app "MyPiece" (Japanese name: おもいでマイピース; the "App").
How your photos are handled (our core principle)
- The App processes the photos you select only on your device to create artwork and generate puzzles.
- Your photos and the converted results are never sent to our servers or anywhere else.
- Access to your photo library is limited to (1) reading a photo you select, (2) reading your library to pick one random photo for "surprise me," and (3) adding a finished artwork when you save it. In all cases photos are only read on your device and are never sent anywhere.
- Puzzles you create are stored only in on-device storage and are removed when you delete the App.
Information we collect
- We ourselves do not operate any server that collects or stores your personal information, photos, or usage data.
- The App has no account registration.
- The App does not display third-party ads, does not collect data for advertising purposes, and does not perform ad tracking. Accordingly, the App Store "App Privacy" label corresponds to "Data Not Collected".
On-device AI
- Subject recognition, difficulty suggestions, puzzle titling, and completion effects are performed by on-device AI (Gemma 4) running entirely on your device. AI features are optional, and you can play puzzles normally without enabling them.
- All AI processing is completed entirely on your device. The inputs (your photos) and generated results used by the AI are never sent to any external server, including our own.
- The App does not send or share your photos or any personal data with any third-party AI service, including cloud-based AI services such as OpenAI, Google, or Anthropic. The AI used for subject recognition calls no external API and runs solely on your device.
AI model download (optional)
Only if you enable AI features (such as subject recognition) does the App download (receive) the AI model file (Gemma 4, provided by Google LLC) from Hugging Face to your device (you can also choose "Later" during onboarding). This transfer receives the AI model onto your device; it does not upload your photos or personal data. This download requires an internet connection, and your IP address and connection metadata are sent to Hugging Face. Hugging Face's handling of this data follows its privacy policy (https://huggingface.co/privacy). No other personal information or photos are sent. You can use the App without downloading the model, and once downloaded, AI processing runs offline.

Sushi Memory Match
Open app detail →These notes apply to the sushi memory game “Sushi Memory Match” (formerly “神経衰弱できるもん おすしやさん”; bundle ID: com.lftfarm.concentration). This is a separate app from Sushi Collection.
Local data
Scores, game records and settings are stored in NSUserDefaults. The app does not send these records to LFT servers. The analytics, advertising, Game Center and purchase services below separately transmit information to their providers.
Analytics (Firebase Analytics / Google)
Screen navigation, interaction events, device and app information, and app-instance identifiers are sent to Google to analyze usage and improve the app. See Firebase’s privacy information and Google’s privacy policy.
Advertising (Google AdMob) and consent
For banner delivery, measurement and fraud prevention, the Google Mobile Ads SDK may collect IP addresses (which may be used to estimate approximate location), device identifiers, ad impressions and interactions, and diagnostic and performance information. Use of IDFA and tracking across other companies’ apps or websites require permission through iOS App Tracking Transparency (ATT). Declining ATT may still allow processing of other information needed to serve ads.
Google’s User Messaging Platform (UMP) presents consent forms according to region and consent status. The advertising SDK starts only when ads can be requested. Google’s privacy policy applies to the recipients and handling of this data.
Rankings (Apple Game Center)
When you use Game Center, scores are sent to Apple. Your nickname and scores may be visible to other players on leaderboards. See Game Center & Privacy.
In-app purchases (Apple StoreKit)
Apple processes purchases of additional content and versus mode. The app checks purchase status; LFT does not obtain or store payment details such as credit card information. Apple’s privacy policy applies.

Corporate Slave Solitaire
Open app detail →Advertising information
The app is offered for free. The iOS version (as distributed on the App Store) displays ads using Meta Audience Network. The Android version currently does not display ads.
On first launch, the iOS version asks for your permission through App Tracking Transparency (ATT). Only if you allow it is the advertising identifier (IDFA) used to optimize ads across other companies' apps and websites (tracking). If you do not allow it, ads are still shown but no tracking takes place. Meta may collect the following information for ad delivery. None of it is linked to your identity.
- Identifiers (device ID, etc.) — for third-party advertising (used for tracking only if you allow it via ATT)
- Usage data (ad interactions, etc.) — for third-party advertising
- Diagnostics (performance, crashes, etc.) — for app functionality
Ad content is determined by the ad delivery service (Meta Audience Network), and the developer does not directly control it. Collected data is handled in accordance with Meta's privacy policy (https://www.facebook.com/privacy/policy/).
World ranking (Game Center / Google Play Games)
The app provides a world ranking feature through Apple's Game Center on iOS and Google Play Games Services on Android. When you use this feature, the following information is sent to and stored by those services and used to display the rankings.
- Player name and player ID (your Game Center / Play Games profile)
- Clear time (your fastest record)
Use of this feature is optional. If you do not sign in to Game Center or Play Games, this information is not sent. We do not store this information on our own servers. It is handled in accordance with the privacy policies of the service providers (Apple Inc. and Google LLC).
How to delete your world ranking data
We do not hold any world ranking data, so you can delete it from each service. Deleting it removes your Corporate Slave Solitaire clear times and ranking records (game data saved on your device is not deleted). The data is kept by each service until you delete it.
Android (Google Play Games)
- In the Google Play Store app, tap your profile icon at the top right, then open Settings → General → Play Games profile.
