MettleKin Privacy

Developer and privacy contact

Y Corp Technologies develops MettleKin and is responsible for this app privacy policy. Privacy questions can be sent to mannykin333@gmail.com.

Privacy posture

Local-only with no account, tracking, analytics, ads, or developer-operated server. MettleKin stores the Crystallin profile and final-form preference, equipment choices, saved workout routines, active routine state, workout entries, motivational muscle points, optional calorie entries, and an optional user-chosen calorie target on the device. The app sends no user data to the developer. Device backups may include app data according to the user's Apple device settings.

Information collected by the app

MettleKin does not collect app data for Y Corp Technologies. There is no MettleKin account, authentication system, cloud profile, developer-operated backend, analytics, advertising, tracking, crash-reporting service, or remote diagnostics service.

Information stored on the device

The on-device save can contain the Crystallin profile and chosen final form, selected equipment, saved routines and active routine position, workout entries, fictional muscle points and unlocked stages, optional calorie entries, and an optional user-chosen calorie target. MettleKin uses these records only to restore the local experience, calculate motivational progress and freshness, continue routines, show history, and display optional fuel totals.

Permissions and Apple-protected resources

MettleKin requests no HealthKit, Apple Watch, location, contacts, calendar, photo library, camera, microphone, Bluetooth, motion, or notification access. It does not read Apple Health or other apps’ workout data.

Third parties, tracking, and advertising

The app includes no third-party analytics, advertising, tracking, social, authentication, cloud-storage, or generative-AI SDK. It does not track users across apps or websites, create advertising profiles, or sell app data.

Network, sharing, and disclosure

The core app makes no automatic network requests. MettleKin has no export or user-directed sharing workflow and sends no workout, routine, progress, or calorie record to Y Corp Technologies or another recipient. Public Support, Privacy, and Safety links open only when the user chooses them; visiting those pages is separate from the local app data described here.

Retention, deletion, and backup

Local records remain in the app container until the user deletes an entry, deletes a saved routine, uses the confirmed Erase all data action, or removes the app. Erase all data removes the primary local save and its in-container recovery copy. MettleKin does not provide cloud sync or export. Apple device backups may contain app data according to the user’s Apple backup settings and may retain an earlier copy after local deletion.

App Store purchase data

Apple processes the paid App Store transaction, Apple Account, billing, redownload, refund, and any Family Sharing information under Apple’s terms and privacy policy. MettleKin does not receive or store payment credentials or a purchase history in its local workout save.

Privacy choices and requests

Users can review and delete individual workout and fuel entries in the app, delete saved routines, or erase all local MettleKin data in Preferences. Because Y Corp Technologies does not receive the on-device records, it cannot access, correct, export, or delete a copy on the user’s behalf. Removing data from an Apple device backup is managed through the user’s Apple backup settings.

Children

MettleKin is intended for adults and is not a Kids Category app. It has no account, social feature, or developer data collection. A parent or guardian should decide whether its exercise and optional calorie-recording features are appropriate for a minor. See the safety boundary.

Security and international processing

On-device records are protected by the security features and settings of the user’s Apple device. Since the app sends no records to the developer, Y Corp Technologies does not internationally transfer or centrally process them. No storage system can be guaranteed completely secure; users should protect their device and Apple Account.

Website and support correspondence

The public Y Corp Technologies website has no account, contact form, analytics, advertising, or tracking script. Hosting and network providers may process ordinary technical request information to deliver and secure the site as described in the company website privacy policy. If a user emails mannykin333@gmail.com, the email service processes the message and attachments so Y Corp Technologies can answer. Do not send private workout, calorie, payment, or health information.

Changes

This policy will be updated before a material change to MettleKin data practices is released.

Users can optionally record positive calorie amounts and, if they choose their own target, see simple progress toward it.

Saved routines, workout entries, and calorie entries remain in local app storage with no MettleKin account, analytics, ads, or developer-operated server.
