Privacy by design

Your records stay yours.

This policy covers iPhone, iPad, and Mac apps published by Luke Kevin McLaughlin, including Calibrate: Fitness & Calories. Calibrate works without advertising, tracking, or a developer-operated account or backend.

No advertising
No third-party analytics
No developer health-data server

Calibrate: Fitness & Calories (build 4)

Calibrate stores the profile choices, goals, meal and workout entries, body measurements, calorie and nutrition targets, calibration history, and settings that you create in the app's private local container on your device. The developer does not operate an account system or cloud database for Calibrate and does not receive a copy of these records.

Optional Apple Health access

You can choose to let Calibrate read supported fitness and body measurements from Apple Health. Access is optional and limited to the categories you approve in Apple's permission sheet. Health information is used in the app to populate your dashboard and records; it is not sent to the developer. You can change access at any time in the Health app or system settings.

Processing on your device

Meal-photo analysis, nutrition-label text recognition, and supported exercise-form processing run on your device. Calibrate does not upload those photos, label images, or camera frames to a developer server.

User-requested lookups

Calibrate makes limited, real-time network requests when you choose features that need current public information. A food barcode can be sent to Open Food Facts for a product lookup. Nearby-place search terms and the location context required for the search are handled by Apple Maps and related Apple services. When you select a restaurant source, the app can request information from that restaurant's public website.

The developer does not retain these requests. Open Food Facts, Apple, the selected restaurant website, and their network providers may receive ordinary request data such as the query, IP address, and technical connection information under their own privacy terms. Calibrate does not include Apple Health records, meal photos, label images, or exercise camera frames in these lookup requests.

Subscriptions

Monthly and annual Calibrate Pro subscriptions are offered through Apple's StoreKit. Calibrate checks Apple's verified purchase and entitlement information to unlock Pro features and respond to renewals, expirations, cancellations, and restored purchases. Apple processes the transaction; the developer does not receive your complete payment-card details.

Calibrate contains no advertising SDK and no third-party analytics SDK. It does not track you across other companies' apps or websites, and it does not send app records to a developer backend.

Information handled by the apps

Learning apps store progress, settings, and saved work locally. Health apps can store profile details, health observations, journal entries, medication and dose records, appointments, care tasks, experiments, and other records that you choose to enter.

Some health apps can also use images that you select and read supported sleep, step-count, active-energy, and body-mass samples from Apple Health. Apple Health access is optional, limited to the categories you approve, and requested only when you start an import.

Storage, collection, and sharing

App records are stored in the app's private local container on your device. They are not transmitted to or stored on a server operated by the developer. The apps contain no advertising SDK and no third-party analytics SDK. The developer does not sell personal data, track you across other companies' apps or websites, or use health information for advertising.

If you explicitly export a backup, report, image, or other record, you choose where it is sent. Information you export is then handled by the destination and its privacy terms. Local notification reminders are scheduled through the operating system when you enable them.

Blitzer direct file transfers

Blitzer discovers nearby Macs, iPhones, and iPads on the local network and transfers files directly to the device you select. Discovery can expose a device name, general device model, app-generated opaque identifier, protocol version, and supported connection type to other nearby Blitzer devices while discovery is active. This information is not sent to a Blitzer-operated server.

A transfer processes the files and folders you select together with the names, relative paths, sizes, timestamps, and verification hashes needed to deliver them safely. That information is sent over the encrypted peer-to-peer connection only after pairing and receiver approval. The developer does not receive, relay, or store transferred files.

Blitzer keeps preferences, transfer history, recovery state, trusted-device fingerprints, and an installation-specific cryptographic identity locally. Private identity material is protected in Keychain. Apple processes the optional Blitzer Pro Lifetime purchase; Blitzer reads the verified StoreKit entitlement on the device and operates no purchase or account server.

Subscriptions and Apple services

Optional subscriptions and purchases are processed by Apple under Apple's terms and privacy policy. An app reads verified StoreKit entitlement status to unlock purchased features; the developer does not receive your complete payment-card details.

Apple processes Apple Health permissions and App Store transactions as the provider of those platform services. You can review Apple Health permissions in the Health app or device settings and manage subscriptions in your Apple Account settings.

Your choices

  • Decline or revoke optional Apple Health and notification permissions.
  • Export a portable backup or report when an app offers that feature.
  • Erase the app's local records from its settings.
  • Delete the app to remove its local container, subject to operating-system backup behaviour.

Support requests

The support form asks for your name, reply email, app, device type, operating-system version, and issue description. This information is sent through the website service and its email-delivery provider so the developer can receive and answer your request. It may also appear in restricted service logs used to ensure a request is not lost if email delivery fails.

Support information is used only to investigate and respond to your request and to maintain necessary correspondence. Do not include health records, payment-card details, passwords, or other sensitive information. You can request deletion of a support conversation by submitting a follow-up request from the same email address, subject to records that must be retained for security or legal obligations.

Children's learning apps: Monster Lunchbox, Oops! Engineering, Little Creature Orchestra, Pocket Rainforest, Color Rescue, The Sentence Machine and Word Witch

Monster Lunchbox is a math game for children, published in the App Store Kids category. It is built so that no personal information about a child is ever collected, stored by the developer, or shared.

What the app collects

Nothing. Monster Lunchbox has no accounts, no sign-in, no names or birthdays, no advertising, no analytics or crash-reporting SDKs, and no third-party code. It does not use the camera, microphone, location, contacts, or photos, and it never sends gameplay or progress to the developer or anyone else. Children cannot message, share, or contact anyone from the app.

What stays on the device

Each of the six chefs is a cartoon monster, not a named person. The app keeps each chef's finished orders, stickers, and difficulty level, plus household settings such as sound and play time, in its private local container on the device. A grown-up can erase any chef's progress in the grown-ups' area, and deleting the app removes everything. Narration is recorded audio included in the app; nothing is generated or sent anywhere while your child plays.

Lunch Club and links

The optional Lunch Club subscription, the restore and manage buttons, and the links to this policy and to app support are inside the grown-ups' area, which asks for a number written in words before it opens. Apple processes Lunch Club purchases and family sharing under Apple's terms; the app only reads Apple's verified entitlement on the device, and the developer never receives payment details.

Oops! Engineering

Oops! Engineering is a building game about simple machines, also published in the Kids category, and it follows the same rules: it collects nothing, has no accounts, advertising, analytics or third-party code, and never sends anything off the device. Each of up to four inventors is shown as a helmet color, not a name. The app keeps each inventor's bolts, challenge builds, Daily Fix-It stamps and saved workshop inventions, plus household settings, in its private local container. A grown-up can reset or remove an inventor in the grown-ups' area, and deleting the app removes everything. The optional Inventor Pass subscription, restore and manage buttons, and the links to this policy and to support are inside the grown-ups' area, which asks a multiplication question before it opens. Apple handles the purchase; the app only reads Apple's verified entitlement on the device.

Little Creature Orchestra

Little Creature Orchestra is a music game for children in the Kids category, where a mouse conductor named Tempo guides a band of woodland creatures. It collects nothing: there are no accounts or names, no advertising, analytics or third-party code, and it never listens through the microphone or sends anything off the device. Songs, the song in progress, stars, Encore levels, concert ticket stubs and settings are kept in the app's private local container. "Reset stars" in the grown-ups' area clears stars and Encore levels, and deleting the app removes everything. Song names are picked from word buttons, so nothing personal is typed. Tempo's voice is recorded audio included in the app. The optional Season Ticket subscription, its restore and manage buttons, and the links to this policy and to support sit behind a stage-door question (a short arithmetic question played on piano keys). Apple handles the purchase; the app only reads Apple's verified entitlement on the device.

Pocket Rainforest

Pocket Rainforest is a rainforest science game for children in the Kids category. It collects nothing: there are no accounts, no advertising, analytics or third-party code, and it never sends anything off the device. Field sites (including the names a child types for them), discoveries, journal notes, Field Season badges and settings are kept in the app's private local container. A field site can be deleted from the station screen, and deleting the app removes everything. The narration is recorded audio included in the app. The weekly Field Season event is chosen from the device's calendar date on the device itself; nothing is downloaded. The optional Pocket Rainforest Plus subscription, its restore and manage buttons, and the links to this policy and to support sit behind a grown-ups' multiplication question. Apple handles the purchase; the app only reads Apple's verified entitlement on the device.

Color Rescue

Color Rescue is a color-mixing, shape and shade game for children in the Kids category. It collects nothing: there are no accounts, no advertising, analytics or third-party code, and it never sends anything off the device. Rescued pictures, paintings made in the paint studio, swatches collected from the weekly Color of the Week and settings are kept in the app's private local container. A grown-up can delete or export a painting from the grown-ups' area; "Reset rescued pictures" clears progress, and deleting the app removes everything. A painting leaves the device only if a grown-up exports it. The narrator's voice is recorded audio included in the app. The weekly color is chosen from the device's calendar date on the device itself; nothing is downloaded. The optional Color Rescue Unlimited subscription, its restore and manage buttons, and the links to this policy and to support sit behind a grown-ups' addition question. Apple handles the purchase; the app only reads Apple's verified entitlement on the device.

The Sentence Machine

The Sentence Machine is a sentence-building game for children in the Kids category. It collects nothing: there are no accounts, no advertising, analytics or third-party code, and it never sends anything off the device. Players (up to six, each a picture and a number), finished challenges, saved Workshop scenes, Weekly Edition progress and its archive, and settings are kept in the app's private local storage on the device. A grown-up can reset a player's progress in the grown-ups' area, and deleting the app removes everything. The narrator's voice is recorded audio included in the app. The Weekly Edition story is chosen from the device's calendar date on the device itself; nothing is downloaded. The optional Press Pass subscription, its restore and manage buttons, and the links to this policy and to support sit behind a grown-ups' check (typing a number written in words). Apple handles the purchase; the app only reads Apple's verified entitlement on the device.

Word Witch

Word Witch (Word Witch: Spelling Spells on the App Store) is a spelling game for children in the Kids category.

A grown-up can reset progress or remove a player in the grown-ups' area, and deleting the app removes everything. The narrator's voice is recorded audio included in the app. The Weekly Spell is chosen from the device's calendar date on the device itself; nothing is downloaded. The optional Word Witch Plus subscription, its restore and manage buttons, and the links to this policy and to support sit behind a grown-ups' check (a multiplication question). Apple handles the purchase; the app only reads Apple's verified entitlement on the device.
