Privacy Policy for MACHINA: Know Your Ride

Summary

• We do not collect, sell, or share your personal data.
• We do not use advertising or third-party analytics SDKs.
• We do not require an account or login.
• Your maintenance records never leave your device, except where you explicitly back them up yourself.

Data You Create

All content you enter — motorcycles, service logs, parts, mileage, fuel logs, maintenance schedules, notification preferences, and any motorcycle photo you add — is stored locally on your device in an on-device database. We have no servers that receive, store, or process this data. We cannot see it.

If you delete the app, this data is deleted with it. Back up anything you want to keep before uninstalling.

Notifications

MACHINA schedules local notifications on your device to remind you about upcoming or overdue maintenance. These are generated and delivered entirely on-device. We do not operate a push-notification server, and we do not collect a push token or any device identifier for notifications. You can disable notifications at any time in your device's system settings.

Third-Party Services

MACHINA is built with the Expo platform. To deliver app updates and ensure stability, the following Expo services may automatically collect limited technical and diagnostic information:

• Expo Updates (EAS Update) — when the app checks for over-the-air updates, Expo's servers may receive your device's IP address, platform, app version, and update/runtime identifiers. This is used solely to serve the correct update.
• Expo Application Services (EAS) — used to build and distribute the app; may process related diagnostic data.

This information is handled under Expo's privacy policy: https://expo.dev/privacy

We do not control and are not responsible for Expo’s data practices. We do not receive personal data from these services.

Photos

You can optionally add a photo to a motorcycle. To let you choose one, MACHINA requests access to your photo library. Depending on the access you grant:

• Full access — MACHINA lists your photos inside the app so you can browse and pick one. This listing happens entirely on your device; we never receive it.
• Limited access (iOS "Selected Photos") — MACHINA can only see the specific photos you choose to share with it, and shows just those for selection. You can change this selection at any time from the app or your device settings.

In all cases, reading your library is done only to display photos for you to pick. We do not read photo location/EXIF metadata. The photo you select is copied into the app’s local on-device storage and shown in the app. It is never uploaded, transmitted, or shared — it stays on your device and is deleted when you remove the photo or uninstall the app.

Saving share cards

MACHINA can generate shareable image cards from your stats. If you choose to save one, the app requests permission to add photos to your library and writes the image there. The card is created on your device; we never receive or transmit it.

Sharing

You can share a generated card or your stats using the standard iOS share sheet. What you share, and with whom, is entirely your choice and handled by iOS — MACHINA does not receive, store, or route shared content, and there is no MACHINA server involved.

Permissions

The app may request these device permissions:

• Notifications — to deliver local maintenance reminders.
• Photo Library — only when you choose to add a motorcycle photo, so you can select an image. You may grant full or limited ("Selected Photos") access; either way the chosen photo stays on your device.
• Photo Library (Save) — only when you save a share card, to write the image to your library.

You may grant or revoke these permissions at any time in your device settings.

Data We Do Not Collect

We do not collect your name, email, contacts, location, advertising identifier, or usage analytics. Photos you add to a motorcycle stay on your device and are never collected or transmitted (see Photos above).

MACHINA reads your device's language and region setting on-device only, to choose a sensible default currency for displaying maintenance costs. This setting is never collected or transmitted, and you can override the currency in the app.

Children's Privacy

MACHINA is not directed at children under 13 and does not knowingly collect personal information from anyone.

Changes to This Policy

We may update this policy as the app evolves. Material changes will be reflected by updating the "Last updated" date above.
