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.
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.
