Privacy Policy — HandyDude

4.1 Local AI

Package: com.ochandydude.localai — on-device LLM/VLM chat client.

• Chat content: your messages, prompts, generated answers, and chat history are processed and stored only on your device. We never see, collect, store, or transmit them, except when you explicitly choose to report a specific AI answer (see Content Reporting below).
• Photos and camera frames: images you attach for vision analysis are processed in memory on your device and are never transmitted to us.
• Voice input: speech recognition runs through the Android system's speech service; audio is not sent to us.

Permissions:

• Camera — optional, to attach photos for on-device vision analysis.
• Microphone / speech recognition — optional voice input, handled by the Android system's speech recognition service.
• Notifications — optional, used for download and status notifications.

Internet usage: the app uses a connection only for (a) downloading AI models from Hugging Face and the model catalog from dev.ochandydude.dev; (b) advertising; (c) in-app purchases and subscriptions; and (d) optional content reports you explicitly send. AI inference itself requires no internet connection once a model is downloaded.

Acceptable use and content reporting. The app may not be used to generate restricted content, including sexual content involving minors, non-consensual intimate imagery, instructions for weapons or explosives, self-harm instructions, extremist or terrorist material, and malware. The app applies automated safeguards to refuse such requests before generation and to withhold matching responses. If an AI answer appears problematic, you may report it using the flag icon shown on that answer. A report transmits only: the single answer you chose to report, the report category you selected, an optional comment you typed (up to 500 characters), the model name, and the app version. Nothing else leaves your device — no chat history, no other messages, no images, no audio, and no device or account identifiers. Reports are sent over HTTPS to dev.ochandydude.dev and used solely to improve content safety. If the device is offline, the report is queued locally and sent later; choosing Cancel keeps everything on the device.

Ads and billing: the free version may display AdMob ads (Section 3.1); Premium/Pro users see no ads at all. Optional Premium purchases and subscriptions use Google Play Billing (Section 3.2).

4.2 LocalClaw — Offline AI Agent

Package: com.ochandydude.localclaw — on-device AI agent that works with your files.

• Chats, prompts, and agent output: we never collect, store, transmit, or share your conversations, prompts, generated responses, notes, or files the agent works with. All processing occurs on your device's hardware.
• Agent actions and your files: LocalClaw can read, list, and write files only in locations you allow — its private sandbox or a workspace folder you explicitly select. Actions classified as risky always require your explicit approval inside the app before they run. File contents are processed on-device and are never transmitted to us.
• Internet usage: downloading AI models from Hugging Face; advertising; in-app purchases; and actions you explicitly ask the agent to perform — for example, cloning a Git repository into your chosen workspace folder. Network access is never required for the AI itself.
• AI-generated content: answers are generated by a language model running on your device and may be inaccurate. Generated content is not reviewed by us before it is shown to you.

Ads and billing: the free tier displays a banner ad on the model manager screen and offers an optional rewarded ad (Section 3.1). Premium users see no ads at all — neither Lifetime purchasers nor users with an active rewarded unlock. The optional Lifetime upgrade uses Google Play Billing; the app stores only an encrypted on-device flag, and purchase restore works through your Google account via Play (Section 3.2).

Audience: the app is intended for users aged 18 and older.

4.3 Secret AI: Offline Solver

Package: com.ochandydude.secretai — on-device AI chat in a disguised, PIN-protected shell.

• What stays on your device: chats, attached photos, your PIN, and settings. Chat history and attached photos live in the app's private sandbox, are excluded from Android backups, and are deleted when you delete them or uninstall. The PIN is stored only as a salted SHA-256 hash — never in plain text.
• AI model files are downloaded once from Hugging Face and then used fully offline; inference never uses the network.
• What leaves your device: model downloads (HTTPS requests to Hugging Face and to dev.ochandydude.dev for the model catalog — a static JSON file; these fetch only file bytes, no personal data is sent), ads on the free tier, and Play Billing purchase checks. Ads never appear in chats or on the cover/disguise screen.

Permissions:

• Camera — optional, only when you choose "Take photo" in a chat.
• Photos — via the Android system Photo Picker; the app gets access only to images you select.
• Notifications — download progress for model files.
• Internet — model downloads, ads, billing. All AI processing is local.

Deletion: "Clear all chats" in Settings erases the local database immediately; uninstalling removes all data.

Ads and billing: the free tier shows AdMob ads (Section 3.1) — never inside chats or on the cover screen — and you can remove all ads by upgrading to Pro or by declining consent where offered. Pro purchases use Google Play Billing (Section 3.2); we only receive a purchase token confirming entitlement.

4.4 Offline AI Expert

Package: com.ochandydude.offlineaiexpert — on-device document Q&A / knowledge base.

• Your documents: documents you import (PDF, TXT, photos for OCR) are copied into the app's private internal storage and are processed only by on-device components (PDFBox, ML Kit Text Recognition, ONNX Runtime, llama.cpp). They are never uploaded anywhere. You can delete imported documents or wipe the whole knowledge base at any time in Settings > Clear Knowledge Base; deletion is permanent and removes the local copies, embeddings, and chat history.
• Network access is used for exactly three purposes: (a) a one-time AI engine download — the language model (~750 MB) and the embedding model + tokenizer (~135 MB) — over HTTPS from Hugging Face, after which the app works fully offline; (b) Google Play Billing purchases and "Restore Purchases" queries (the app only receives a purchase token and the localized price string); (c) ad serving on the free tier — no document content, prompts, or chat data is ever sent to the ad network. No other outbound requests are made; there is no app backend server.
• Backups: the app follows standard Android Auto Backup rules but explicitly excludes the downloaded AI models, imported document copies, and the vector database from backups.

Ads and billing: the free tier shows a small AdMob banner in Settings and offers an optional rewarded ad that unlocks PRO features for 24 hours (Section 3.1); buying PRO removes all ads permanently via Google Play Billing (Section 3.2).

4.5 Stella: Bedtime Stories

Package: com.ochandydude.stella — on-device AI bedtime stories with text-to-speech narration, made for families.

• Stories and profiles: story texts, character details, your child's name or age entered for personalization — all are processed and stored only on your device. We never see, collect, store, or transmit them.
• Narration uses your device's built-in Android Text-To-Speech engine; no audio leaves the device.
• Permissions: Notifications (optional, used for download and status notifications) is the only sensitive permission requested.
• Internet usage: downloading AI models from Hugging Face and the model catalog from dev.ochandydude.dev; advertising; in-app purchases and subscriptions. Story generation and narration require no internet connection once a model is downloaded.

Children: the app is designed to be safe for family use — all content is generated and stored on-device, we collect no personal information from anyone (including children), ads can be fully removed via the Pro upgrade, and a parental gate protects purchase and settings areas.

Ads and billing: the free version may display AdMob ads (Section 3.1); Pro users see no ads at all. Optional Pro purchases and subscriptions use Google Play Billing (Section 3.2).

4.6 HookTime (Fishing Forecast)

Package: com.ochandydude.hooktime — on-device fishing forecast with maps. Server-free by design: we operate no backend for this app, there are no user accounts, and all forecast computation happens on your device.

Location data. The app requests your location once during onboarding (and optionally later) for a single purpose: to find the nearest fishable water (sea shore or lake) and to pick the correct forecast point and time zone. Your coordinates are:

• processed on your device against the offline geographic dataset bundled with the app;
• stored only locally on your device (approximate forecast point and GPS fix);
• never sent to any server operated by us — we have none.

Third-party data providers. To compute forecasts and render maps, the app contacts the following free public services directly from your device: MET Norway (api.met.no) for weather forecasts; NOAA (nomads.ncep.noaa.gov, api.tidesandcurrents.noaa.gov) for wave model data and US tide predictions; OpenStreetMap tile servers (tile.openstreetmap.org) for base map tiles; Esri ArcGIS Online (server.arcgisonline.com) for ocean depth (bathymetry) basemap; and the Overpass API (overpass-api.de) for protected-area boundaries. Those requests necessarily include the coordinates of your forecast point and are made from your IP address; each provider may log requests under its own privacy policy. No personal identifiers are included, and we have no access to these requests.

Notifications (optional, Android 13+): the app can alert you when a high-efficiency fishing day is coming. Alert computation runs on your device; no data leaves it for this feature.

Ads and billing: the free version can display AdMob interstitial ads when you voluntarily unlock additional forecast days or map layers (Section 3.1); Premium users see no ads at all. Premium — subscriptions (monthly or yearly) or a one-time lifetime unlock — uses Google Play Billing (Section 3.2).

Terms of Use for this app (informational-use and no-warranty terms, subscription details, third-party content attribution) are published separately at dev.ochandydude.dev/fishing-terms.html.

4.7 AI Morse Link

Package: com.ochandydude.morselink — optical (light-based) messaging between two phones.

• Messages: text you send or receive is transmitted optically (device flashlight to camera), end-to-end encrypted with a key derived from your pairing code. We operate no messaging servers; we never see, collect, store, or transmit message content. Messaging itself requires no internet, Wi-Fi, Bluetooth, or cellular connection.
• Camera frames: the camera is used only to measure light intensity for signal decoding. Frames are analyzed in memory on your device and are never recorded, stored, or transmitted.

Permissions:

• Camera — receives the optical signal (luminance sampling only, no recording).
• Flashlight — transmits the optical signal (no permission prompt needed on most devices; controlled via camera APIs).
• Microphone / speech recognition — optional voice input for message dictation, handled by the Android system's speech recognition service.
• Location — optional, used only inside the SOS beacon to embed your GPS coordinates into the locally broadcast optical message. Never sent to us.

Internet usage: downloading the optional AI compression model from Hugging Face and its catalog from dev.ochandydude.dev; advertising; the in-app purchase.

Ads and billing: the free version displays AdMob ads (Section 3.1); Premium users see no ads at all. The optional one-time Premium upgrade uses Google Play Billing (Section 3.2).

4.8 Cubrix: Block Puzzle Game

Package: com.ochandydude.cubrix — block puzzle game with an on-device AI companion.

Data stored locally on your device (via Android DataStore, never transmitted to our servers): game progress, high scores, and statistics (games played, lines cleared); unlocked in-game themes and inventory items (gems, power-up boosters); in-game preferences (sound effects, haptic vibration, daily notification toggles).

Third-party services used by this app:

• Google AdMob — rewarded video ads that provide free in-game perks (Section 3.1).
• Google Play Games Services — supports cloud achievements and global high-score leaderboards. When you sign in to Google Play Games, your public gamer profile and high scores are managed by Google under Google's Privacy Policy.
• Google Play Billing — all digital purchases (gem packs, premium themes) are processed by Google Play; we do not receive, store, or process any card or banking information (Section 3.2).

On-device AI companion: Cubrix includes an optional on-device AI companion (a trainable neural pet, player-vs-AI duels, and a decision log). The AI model is trained locally on your gameplay patterns on your own device. All AI training data, learned model weights, and related game statistics remain exclusively on your device and are never transmitted to our servers or to any third party. Clearing the app's data or uninstalling permanently removes the companion's learned data.

Local notifications: if enabled in settings, the app schedules local notifications to remind you of daily puzzle challenges, handled locally by Android WorkManager/AlarmManager without external telemetry or tracking.

4.9 OIG — Offline Image Generator

On-device image generation.

• Prompts and generated images: we never collect, store, transmit, or share your prompts, generated images, or source photos you transform. All processing occurs on your device's hardware.
• Internet usage: downloading AI model weights (GGUF files) from Hugging Face; advertising; in-app purchases. Once a model is downloaded, all generation features work entirely offline.
• Acceptable use and content reporting: the app prohibits generating restricted content, including sexually explicit or suggestive material, content exploiting minors, and content intended to harass or deceive. Prompts are screened on-device before generation, and the screening rules are periodically updated from our server (dev.ochandydude.dev). A content-reporting feature lets you flag generated images; reports are sent to our server (or queued locally when offline) and reviewed by the developer.

Ads and billing: the free tier is supported by AdMob ads (Section 3.1); upgrading to PRO removes all ads. PRO upgrades (subscriptions and one-time purchases) use Google Play Billing (Section 3.2).
